June MSC SUMMARY (Part 2) – Danny Kleinman, Director

Problem D  2 !S  (YleeXotee, JCreech, Hoki)

Matchpoints  Neither side vulnerable
You, South, hold:

♠ J 9 3    A K J    A K Q 10 4   ♣ J 7

SOUTH   WEST   NORTH   EAST
  ——       1 ♠       Pass      Pass
Double*   Pass     2        Pass
   ?         
*BWS: 2 NT would have shown 18-19 HCP

What call do you make?

The opponent's opened 1 !S, and you balanced with a double.  Partner bid 2 !H and the auction is back to you.  You have 19 HCPs that you were unwilling to balance 2 NT originally due to the Jxx stopper, but this 19 has both flaws (unsupported jacks) and the diamond suit makes the hand rate somewhat better.

3    40   BWP 1 Panelist   BWS 9% IAC No solvers
Robert Wolff "Best of several choices, two other being two notrump and pass."

2 NT   30   BWP No Panelists   BWS 3% IAC No solvers 
No Panelist or IAC solver chose this option, but it reasonably ought to be on the table.  At your first turn, you could have bid 2 NT immediately to show these values, but did not.  What would be different at this turn?  First, you are not raising hearts, so the reopening double was not based on four hearts.  Second, without four hearts, to suggest notrump at this turn also indicates less than a full stop - so this should warn partner off with two or three small.  In other words, if notrump is wrong, partner should be able to work it out, though my partner never seems to.

Pass   50   BWP 7%   BWS 9% IAC 1 solver
There are a lot of losers for partner to cover, so there are pessimists finding a pass.  WackoJack has a fairly complete analysis: "Yes, a nasty problem.  Optimistically: West opened with 12 East has 3.  So partner has 6. Maybe:   !S Axx.  !H Qxxxx,  !D xx,  !C xxx. That just about makes 4 !H a good contract.  BUt only just.  Pessimistically:  West opened with 15, East has 3.  So partner has 3.  Maybe:  !S xxx  !H Qxxxx,  !D Jx,  !C xxx.   You lose 5 tricks off the top.  So at match points it is tempting to pass."  Irina Levitina is "Going for a plus.  Too many losers make it too risky to bid."  BluBayou: "If we raise to 3 !H , they may grab 5 off the top as discussed above, on top of that, partner may not realize that his 5-6 count  is what we need for game  (Qxxxx + club king, or diamond jack?)"  Marty Bergen thinks "Anything could be right.  I considered two notrump, which was perfect except for one very large flaw."

2 ♠   100   BWP 52%   BWS 45% IAC 43%
An interesting new rule emerged.  Joel Wooldridge:  "This matches a rule of mine: a takeout double followed by a cue-bid most often shows three-card support for advancer's suit and about 18 high-card points.  Other hand-types are possible, but this is what partner should assume, as it's the most common."  Clearly other subscribe to this rule.  For example, Brian Platnick describes the bid:  "The most-likely hand for cue-bidding here is extras with three-card support."  Similarly, Phillip Alder writes: "Surely this cue-bi, which typically shows a strong hand with three-card support for partner's major, will win in a landslide."  Zia:  "Two spades implies fewer than four hearts, most likely three."  Others are less certain.  JCreech is awaiting further developments:  "A nebulous cue-bid.  I want to show support, but leave room for more description.  This cue takes up the least space, and maybe I will hear something I like."  As are Hoki: "in the hope of coping with any continuation (3D over 3C should show heart support)" and Jeff Alexander "I hope partner will know what to do."

3    80   BWP 37%   BWS 33% IAC 43%
The last real option is to bid the fine diamond suit.  My tendency when faced with this sort of situation is to overcall, then double on the next round, but then I am not usually starring at 19 HCPs along with a diamond suit this nice.  Masse24 writes:  "Really tough problem. 2 Spades is tempting, to elicit more information, but that’s a game-force and I’m just a bit short on values. 3 Hearts (my second choice) with only three is also tempting. But 3 Diamonds gets my values across and leaves the door open for partner to continue with a few values."  Frank Stewart thinks "Maybe a slight underbid, but the black jacks may be wasted, and I see no alternative."  Bart Bramley focuses on the number of hearts: "To the point.  Implies three hearts, else I should have bid three diamonds initially."






Problem E  4 !D  (BluBayou, Hoki, JCreech)

Matchpoints  Neither side vulnerable
You, South, hold:

♠ A J 2    A Q 6 4 3 2    —   ♣ A K J 6

SOUTH   WEST   NORTH   EAST
  1        Pass       1 ♠       Pass
  3 ♣       Pass       4 ♣       Pass
   ?         
What call do you make?

You have a big hand and have elicited support for your second suit, as well as three-card support for partner's first-bid suit.  I agree that you have first-round control in all of the suits, along with your 19 HCPs, but is this enough to force to slam opposite a hand that really hasn't shown any strength beyond the 5-6 needed to make a one-over-one response.  However, Marty Bergen doesn't like the presented auction:  "To say that I object to the way-beyond-absurd one-heart opening would be the understatement of the century."

5 ♠   30   BWP 1 Panelist   BWS 0% IAC No solvers
Forcing the issue and providing the maximum choice, Bart Bramley thinks the bid "Logical choice of slams.  In my world, South guaranteed at least four clubs and denied four spades, so partner should make the right decision.  I might miss a good seven, but I want to bring spades into the picture, and four spades wouldn't be forcing."

5    50   BWP 11%   BWS 2% IAC No solvers
Also forcing the issue, but with what meaning?    Robb Gordon thinks "This hand is a poster child for Exclusion Key-Card."  But is it Exclusion or is it a splinter?  Four diamonds is not a jump, so it is not typically a splinter.  And one thing it does not do is show support for spades, yet Billy Eisenberg claims it "Should convey the gist of my hand."  What it does do is commit our side to a slam in clubs without any certainty that we have the values to be there, much less an eight-card or better fit.  This feels like trying to reach the seven-level without being certain we want to be at the six-level.

6 ♣   50   BWP 11%   BWS 5% IAC No solvers
I consider this to be a more honest approach.  Jeff Alexander says "Four spades would show four-card support and might end the auction.  Maybe North has: ♠ Kxxx    x    xxx   ♣ Q10xxx, and we'll get lucky."  Kit Woolsey gambles:  "I'm not going to stop in five clubs when we might have an eight-card major-suit fit found by the field.  Six clubs probably has play whatever partner has and I don't see any sensible way to find out if there is a better contract."  Joel Wooldridge "I treat raises of minor-suit jump-shifts very seriously.  For four clubs, I expect North to have either a fifth club or slammish values.  With anything less, he might have take a three heart preference on a doubleton or punted with four diamonds. ... if I bid six directly, partner can infer that I wasn't merely trying for six, and he may be able to bid seven himself."  Joel, it is good to have agreements of that sort, but are they applicable to BW2017 without additional discussion?

4 ♠   70   BWP 26%   BWS 22% IAC 57%
Masse24 has good questions as he makes this choice:  "This one confuses me a bit. I think 4 Diamonds will be the popular solver choice, but it doesn’t feel right. Can 4 Spades be interpreted as shaping out? Can it be passed? It is Matchpoints."  Frank Stewart says "This sequence describes the hand reasonably well."  Carl Hudecek thinks "Partner had a chance to control-bid or to show heart preference at the three-level.  He didn't, so I go lightly with four spades, which shows some spade support."  Drew Casen shapes out:  "Didn't I already say I have a game-force with at least five hearts and four clubs?  Now partner will know 12 of my cards, and any further move will be up to him."  Doub and Wildavsky's plan is "If partner bids five clubs, we'll bid again, so he won't worry that we lack a diamond control."  Eric Kokish believes that "In the unlikely event that North has the heart king, he will love it.  If partner has short hearts. he will love the spade king and a fifth club."  Jeff Rubens: "Strong controls and clubs, yes; but the queen of hearts is only a medium-value slam-level card, so I won't push too hard."  One thing is certain, these experts do not generally think that the bid necessarily shows a fourth spade.

4    100   BWP 48%   BWS 62% IAC 43%
BluBayou: "Most MSC panelists have no objection to a phony jump-shift on this auction.  They and I have to pay the piper this time:  slam in clubs is so likely that we cannot support spades right now; we must confirm our fit and cue in diamonds.  There is a fair chance that spades and clubs both make the same tricks, and that we won't be able to get back to the major :( . .....   I regret that I have to give up on patterning out  with delayed spade support and  that not doing so  may hyrt a lot."  Kevin Bathurst says "I'll start control-bidding and hope that partner can show second-round heart control at the five-level on the way. I'll reach at least six clubs, hoping that we can find a way to feel confident about seven."  Nick L'Ecuyer feels it "Must be the right way to start.  Let's see what partner does."  Zia admits "We need cooperation from partner to determine the right level.  (1) Will his four hearts next suggest a place to play? (2) Are we sure that he has the queen of clubs?  (3) Might he have marked time with three diamonds if he didn't?  Too many questions, too few answers."  Nonetheless, David Berkowitz feels that "Partner's not bidding three diamonds is quite encouraging."  And Brian Platnick points out that "Except in a regular partnership with elaborate agreements, this is a very-difficult auction.  Would partner's four hearts or four spades next be an offer to play?  I would assume yes, so four notrump will be partner's only slam=try over four diamonds."  Then there are those who just cannot bear to hear partner pass 4 !SJCreech: "To show shape or to cue-bid?  I think I will cue-bid rather than imply the shortness.  Since I hope to be slamming, I won't like bidding 4 !S and then hear pass."  Phillip Alder: "If I knew partner wouldn't pass, I would bid four spades; but he probably would pass.  So I will control-bid and hope for the best."  Hoki: "a cue bid with maybe 4S to come (over 4H)"





Problem F  4 !H  (BluBayou, Masse24)

Imps  East-West vulnerable
You, South, hold:

♠ J 7 5 4    Q J 10 7 5    Q   ♣ 10 9 8

SOUTH   WEST   NORTH   EAST

   ?         
What call do you make?

I find this auction confusing.  Partner opens 1 !D, then bids a second suit at the one-level which does not necessarily show extras.  Some of the Panel have even suggested that 1 !S should be passed.  Marty Bergen, for example wrote:  "Although two spades may have worked out well, I object to it.  With this collection of quacks, even when vul., to pass one spade was clear."  Then when I raise that second suit, he raises my first suit.  Is this a true raise, a game try, or something else?  The Panel clearly behaves as though the hearts are natural, but are they?  For some Panelists, it isn't even clear that 3 !H is forcing.

3 ♠   40   BWP 7%   BWS 31%  IAC 43%
I think that JCreech is expressing the fears and hope of the hand: "I am tempted to pass, but then is partner bidding out their shape or cue-bidding.  I'll retreat to our 4-4, and hopefully showing a hand that is weak."  Jeff Rubens admits "The bidding has improved the hand, but I'm not sure it was worth two spades in the first place."  While Arthur Robinson just says "I assume three hearts is forcing."

4 ♠   40   BWP 7%   BWS 19% IAC No solvers
Although certain that partner has both majors, Kevin Bathurst at the end makes a guess: "This hand sure grew up fast.  I might have passed one spade, but now I must bid game.  If partner has good diamonds, spades may be better; but if he has good controls, hearts may be easier to manange except perhaps on a trump lead.  I'll guess spades."

4    100    BWP 67%   BWS 29% IAC 29%
A majority of the Panel are certain that 3 !H was offering an alternative strain.  Carl Hudecek thinks "With partner probably void of clubs, I'd rather ruff clubs with hearts I don't need for tricks than let the defenders force partner to ruff with useful spades."  David Berkowitz finds it "Easy to see South's spades going on North's diamonds."  Similarly, Jeff Alexander believes "Game should have a play in hearts, as spades may go on diamonds."  Nick L'Ecuyer bases he decision on the relative strength of his two suits: "Game can make.  Looks as if partner has a decent 4=3=5=1.  With stronger spades, I would bid four spades."  As does, Doub and Wildavsky: "Pass was a standout over one spade, but having raised we've hit the jackpot.  We'll choose the stronger suit for trumps."  Masse24: "We belong in Hearts since Club ruffs need to be taken in the short hand. Even if we only get one ruff I can envision game, so I will accept. Partner should have a 4=3=5=1 hand with 16 (or possibly 17) HCP. Maybe a hand like: !S KQ93 - !H K94 - !D AKJT7 - !C 2 ???  Can that hand make game? I hope so."  Robb Gordan: "The five-three fit will be better than the four-four.  If dummy gets tapped and trups split badly, partner won't be able to use all the hearts in a spade game."  Phillip Alder will "Take the ruffs in the shorter-trump hand.  I do not expect to need discards on the long hearts, and the spades are weak."  Eric Kokish: "Suddenly an excellent hand, but not good enough for four clubs."  Kit Woolsey says "This piece of junk just became a lot more valuable.  If partner has the 4=3=5=1 shape he has portrayed, four hearts figures to be better than four spades."  BluBayou is "Expecting a dummy equivalent to AKxx, Kxx, AKxxx, x to go with our 'measly'   Jxxx, QJTxx, Q, Txx!  The panel may say "THAT  is a jump-shift to 2 !S , so pray hard, Blu!", but  I'm standing firm."  Drew Casen is reluctantly drug along: "I would have passed one spade, and I'd also pass three hearts if not vulnerable at imps."

Pass   60   BWP 19%   BWS 20% IAC 29%
This last group believe partner's heart bid, but are satisfied either with the final strain, or at least not terribly discontented.  Whether they view 3 !H as forcing is not clear, but if they do, it doesn't matter.  Robert Wolff  is simply done:  "Which I might have done last turn but didn't lest West enter in clubs."  Hoki writes:  "haven't I already bid my hand (if not overbid it, lol)"  Brian Platnick thinks the strain has improved: "Presumably, partner is 4=3=5=1 with extras but short of a jump-shift.  Hearts may play better than spades." 



This ends Part 2.  Hopefully you find something interesting or thought provoking.  Until the lasr part is ready, please join in nrxt month's problem set.

June MSC SUMMARY (Part 1) – Danny Kleinman, Director

Problem A  4 !D (VeredK, BluBayou)

Imps  Both sides vulnerable
You, South, hold:

♠ K 4 2    A K Q 6    —   ♣ Q J 7 6 3 2

SOUTH   WEST   NORTH   EAST
  1 ♣       2 NT*     3 ♣     Pass
   ?         
*red suits; any strength

What call do you make?

You opened 1 !C with six, when you could have easily only had three, the opponents show both red suits, and partner raises.  Partner had the ability to show a stronger club raise through unusual vs. unusual, so he is clearly limited by the decision to not use a cue-bid. According to BWS2017, North is limited to less than a game-invitational raise of clubs.
 
5 ♣   50   Bridge World Panel (BWP) 11%   Bridge World solvers (BWS) 20 Intermediate/Advanced Club (IAC) 57%
The low road was not a popular approach by the panel, but it was the majority choice of IAC.  Hoki says "although I did toy with that fancy idea of trying a 4D splinter bid (but rejected that idea as being too much pie-in-the-sky stuff when it is not even certain that we can make game)"  Similarly, JCreech doesn't "... see much chance for a slam, so I will holster the cue-bids and just bid the club game."  Masse24 thinks it "Should have play. An exploratory splinter, or even 3 !H (my second choice) accomplishes what? What sort of perfecto does partner need for slam to be decent?"  David Berkowitz argues "No call seems appropriate, so I will try to buy the contract.  Feels like partner is 3=1=4=5, but who knows how to reach slam opposite ace-king-fifth in clubs?  At least I've shut out four diamonds."  And Robert Wolff will "... probably bid six if pushed but I can hope that an opponent doubles five clubs."

3    70   BWP 30%   BWS 36% IAC 1 solver
It is not clear how best to start the cue-bidding process.  The heart bidders thinks it show a concentration of values.  Doub and Wildavsky says "Bidding where we live.  We can't yet picture partenr's hand well, so we'll show ours."  similarly, Drew Casen: "I like to bid where I live.  If partner bids three notrump, I will probably settle for five clubs.  If partner does not bid three notrump, I will look for six clubs."  Frank Stewart is "Heading for six clubs if I can receive just a little cooperation from partner.  Over four clubs, I will try four diamonds."  Jeff Alexander thinks that "If partner doesn't bid three notrump, slam is in the picture.  Partner figures to have fewer than five cards in the majors."  Kevin Bathurst feels "Slam may be excellent if partner if partner has the spade ace and a high club honor, but more likely he's loaded in diamonds.  I won't pass three notrump, which could fail if we have only one stopper in diamonds or spades so I'll keep looking for a club slam."  Irinia Levitina "If partner bids three notrump or four clubs, I'll bid five clubs.  If he bids three spades or jumps to five clubs (showing strong clubs), I'll bid six clubs."  Typically, with the opponents showing two suits, a cue-bid shows a stopper in the bid suit and is seeking a stop in the other suit; it seems like 3 !H is placing the emphasis on the wrong suit, seeking wastage rather than useful controls.

4    100   BWP 52%   BWS 23%  IAC 29%
By the barest of majorities, the Panel has slam in their eyes via a splinter.  BluBayou discussed the limits imposed with a simple raise under BWS2017 before saying: "I guess that rules out partner having Axx,  xx, Qxxx, AKxx for our  Kxx, AKQx, --, QJxxxx (or even similar with five trumps)?  So shall we bid the simple cuebid of 3 !H  hoping to hear 3 !S  OR 3NT (Will be ugly if we don't have running clubs)?  No--  I will remove the temptation to land in 3NT and stay with the knee-jerk SPLINTER."  Kit Woolsey is "Showing diamond shortness and slam interest.  If Partner control-bids four spades, I'll bid slam.  If partner has both top clubs, he can work out that he has the right cards."  Eric Kokish thinks "With two key cards, North won't stop short of slam, which might still take some luck if those cards are the ace and king of clubs."  Carl Hudecek believes "Partner will interpret this as a cue-bid slam-try.  He can control-bid the sueful ace of spades, or sign off in five clubs with a hand like: ♠ Jxx   xx    xxx   ♣ AKxxx."  Marty Bergen: "A splinter, not an-ask.  Slam is on the horizon."  Billy Eisenberg is "Hoping for a spade control-bid."  Nick L'Ecuyer: "I don't need much to make six clubs, so I'll try for it. Partner won't control-bid hearts but may well control-bid spades.  I'll bid six clubs over any sign of life."  Zia says "A four-spade bid from partner will turn me on."  Jeff Rubens: "I'll bid six clubs over four spades."  I like Robb Gordon's thoughts best: "I don't need much for slam and want to elicit information below five clubs."  Coupled with Bart Bramley's: "Should get partner to focus on the right things.  ... I will bid slam over any positive move."  Which leads to Ron Smith's "We could have a slam on a good day."

My problem with most slam tries with this hand is whether North would be showing a first-round or second-round control.  When dealing with a minor, it is easy to get too high.  In those situations, I find it better to bid the game that is almost certain to make, than to stretch for a slam that might risk turning a plus into a minus position at imps. 



Problem B  1 NT  (CCR3, Hoki, YleeXotee, JCreech, Masse24)

Imps  Neither side vulnerable
You, South, hold:

♠ Q 8 6 4    A 10    K J 6 2   ♣ 10 5 4

SOUTH   WEST   NORTH   EAST
  ——       1 ♣        1       Pass
   ?         
What call do you make?

LHO opened 1 !C, partner overcalled 1 !H, RHO passed and you have 10 HCPs in a semi-balanced hand with no stopper in the opponent's suit, and only doubleton support for partner.  Not a lot of outstanding choices. Robb Gordon summarizes nicely: "A typical Master Solvers' Club dilemma:  bid notrump without a stopper, raise on a doubleton, or bid one spade with only four."
 
Pass   30   BWP 1 Panelist   BWS 5% IAC No solvers
The alternative that did not occur to most, but upon reflection, has a lot to offer is the simple pass.  Carl Hudecek thinks "The auction isn't over yet.  East's pass has made the auction more difficult for me."  In these days of negative doubles, the virtually automatic reopening double makes pass a standout.  Wouldn't you be willing to take your chances with 1 !H doubled if passed back to you?  And if it isn't, then you may have a better option available to you.

1 NT   100   BWP 74%   BWS 4% IAC 71%
A strong majority of the Panel and IAC show their shape and good values.  Although the points may be toward the top, the important thing is to show the shape and not worry about stoppers.  Bart Bramley considers the bid to be "Closest to what I have. One notrump should be safe, and three notrump is our most-likely game on the evidence so far.  Still time to find other strains.  Pass, one spade, and heart raises all pale in comparison."  JCreech argues "I am a maximum for my bidding, but then a minimum for my stopper.  I don't want to introduce a four-card suit, even at the one-level.  I will settle for my least of evils/ best of descriptions."  Phillip Alder: "I would prefer a better suit to bid one spade on four.  I also would prefer better clubs for one notrump, but the hand is too strong to pass."    Masse24: "Ten third is stopperish. Keeps things alive if partner has more to say."  Zia: "some prefer one spade, but I'd like four better spades when I have this club stopper."  Eric Kokish argues "It's just the one-level - lots of time to look for a better strain."  Hoki is "second-guessing the panellists who normally don't give a stuff about piffling things like stoppers (at the table I'd probably agree with 1S)"

1 ♠   50   BWP 15%   BWS 32% IAC 1 solver
Hating to bid 1 NT without a stopper, something to try bidding 1 !SMarty Bergen says "I believe strongly that after partner overcalls, advancer's new-suit bid at the one-level should be forcing with four or more cards in the suit."  Kevin Bathurst: "If this may be based on as few as four.  I prefer it to one notrump, my close secnd choice, which may fail when West has genuine clubs."  Nick L'Ecuyer is "Keeping everything in the picture.  A fifth spade would be nice but I don't have one."  Marty clearly feels that an advancer should bid similar to a responder, but the moderator, Danny Kleinman, thinks the advancer's bid is "... non-forcing, (so) a one-spade advance should deliver a decent five-card suit or better.  One spade keeps one spade in the picture, and that may be the final contract if North has a garden variety one-heart overcall with a balanced hand, e.g.:  ♠ Kx    KJ98x    xxx   ♣ AQx."

2    40   BWP 7%   BWS 12% IAC No solvers
And then speaking for those who would raise.  Joel Wooldridge writes "One notrump and two hearts look good.  I prefer two hearts with no club stopper."  I have seen worse doubleton raises than A10-tight.

2 ♣   0   BWP No Panelists   NWS 3% IAC 1 solver
I will present one more option; the nebulous cue-bid.  To tell the truth, similar to the "Pass," this has more merit than the polling indicates.  BluBayou "We have everything we need for a cue-advance of pard's 2 clubs, except a third trump.  I am doing this anyway:"  If you had a third heart, this would probably be a standout first or second choice.  It gives partner a chance to show a second suit or a stopper, if inclined toward notrump.  The problem is that it is also an aggressive bid with no sure fit or stopper.  I am certain that the Panel also looked at vulnerability and were not being pushy with our side white.





Problem C  2 !D  (Masse24, JCreech, YleeXotee, Hoki, CCR3, VeredK)

Imps  East-West vulnerable
You, South, hold:

♠ A Q J 10    Q 8    Q J 10 8 5   ♣ 4 2

SOUTH   WEST   NORTH   EAST
  ——       1         2 ♣      Pass
   ?*         
*BWS: new-suit bids nonforcing

What call do you make?

Partner has overcalled opener's 1 !H with 2 !C, so you, if you bid, would be the advancer.  You have 12 HCPs, doubleton support for partner, and both remaining suits, including five decent diamonds.  The hint indicates that all new suit bids are nonforcing, so a cue-bid is the only forcing bid.  Is this hand worth forcing with?  And surely a new suit would show at least constructive values; opposite what constitutes an overcall these days, what do you need to show a new suit?

3 ♣   30   BWP 1 Panelist   BWS 0% IAC No solvers
Let's start with the truly awful.  Jeff Rubens says he "Can't bring myself to pass with all these honors, however queeny."  Doubleton support and 12 HCPs?  It seems a bit much for a courtesy raise Jeff, but perhaps you have seen more terrible overcalls than I have.

2    40   BWP 7%   BWS 19% IAC 1 solver
How about making a forcing bid?  You do have 12 HCPs, and cue-bids in response to an overcall are more often of a nebulous nature - make a one-round force now and clarify whether it is a raise or something else later.  Brian Platnick thinks "North may expect better clubs or a slightly stronger hand, but this is superior to two diamonds."  BluBayou is only thinking in terms of a raise:  "We have everything we need for a cue-advance of pard's 2 clubs, except a third trump.  I am doing this anyway:"  The only thing keeping me from the cue-bid is what is my next bid?

Two diamonds feels as though it is a bit wimpy.  Phillip Alder makes a pitch for the non-systemic approach: "I prefer to use a new-suit advance as forcing, so that a cue-bid guarantees support for partner's suit.  But if partner passes two diamonds, I doubt that we will have missed game."  Kit Woolsey remarks:  "I was surprised that the BWS voters made new-suit advances of two-level overcalls nonforcing, but if partner passes two diamonds we probably won't be missing anything."  Robert Wolff says "And await developments.  I hope I'm not left here; but if I am, two diamonds may turn out well enough, especially at imps, where playing in the lower-scoring strain matters little.  I'll bid spades next in the unlikely event that I can do so conveniently."  Bart Bramley feels that "With no known fit and no sure heart stopper, game is a long way off.  Take it slowly and hope that something good happens, which could include all pass."  JCreech argues "I may be a bit heavy for my bid, but it is the best description.  I can tolerate partner's suit and I want to make a constructive move.  This satisfies those desires without going crazy."  Irina Levitina thinks that "Even if it is not forcing, it still must be constructive."  Similarly, Hoki says "forward-going but non-forcing constructive in standard is fine"  Carl Hudecek: "The downside to two diamonds is that part may lead diamonds if West buys the contract, but I'm willing to take that risk.  This hand is too strong to pass partner's two-level overcall."  Doub and Wildavsky: "Not forcing, but nothing compels partner to pass."  Kevin Bathurst is "Resisting the temptations to treat my four strong spades as though I had five and to bid two notrump to protect the doubleton queen, but I may be able to do that later."  Masse24 makes a prediction:  "Unanimous?"  Todd, you were close, but there was even a dissenter among the IAC.

2 NT   50   BWP 15%   BWS 9% IAC No solvers
Except for one missing element, this would have been my choice.  With more than the constructive values of a new suit and stoppers in both unbid suits, this bid seems ideal until you get to a stopper in the opponent's suit.  Even there, you have a partial stop with Qx, and even the best location for that partial stopper if you bid the notrump first, but I would not like to be in a notrump contract with Qx opposite air.  Eric Kokish writes: "This hand suggests suit play, but two diamonds and two spades are length-short and high-card heavy.  If the heart queen is worth something it's in notrump.  We can get out of notrump if that looks better to North."  I'm afraid that once you have promised a heart stop, partner will take you at your word.  I agree with Jeff Alexander: "If we belong in notrump, I should declare.  I don't see how cue-bidding two hearts would help."  But I am not raising my hand without encouragement from partner, unlike Zia, who wants to "Grab it while it's hot."


This ends Part 1 of this month's summary.  Despite two very concentrated votes, I found some of the minority selections particularly intriguing.  I hope you found something of interest as well.  Once you finish, think about going to the current month's problem set.  Who knows, maybe we will see Ken Berg triumphant return, or Curls  (who we haven't seen since she has turned into a Yellow) participate.  Anyway, any and all who do participate are welcome; the more the merrier.

Initial thoughts.

Problem A:  ?  I don't like my options at this point.  Partner punted in such a way that I have trouble showing both my fine suit, my extras, as well as a solid fit for the other major and great controls.  Too much to show, and no room to show it.

Problem B:  3 !C  Despite my balanced shape, I think it is right to show support.  Except for the !S Q, the values are generally better for suit contracts.  If we belong in NT, it should be from partner's side of the table.

Problem C:  3 !S  A punt.  I am still not certain about the strain, and I don't want to bypass 3NT when that is a possibility.  Second choice is 3NT based on Hamman's Law.

Problem D:  3 !C  I am torn between 3 !C and Pass.  I think the values are close to Pass, but I fear the long clubs and stiff !D K.  I will feel better doubling 3 !S, if given a chance.

Problem E:  3 !C  I think just freely bidding at the three-level implies extra values.  Perhaps not quite as good as this, but close.

Problem F:  3 NT  Showing stoppers and some decent general values, but not much of a spade fit.  I wishh I had a second spade, but perhaps I can borrow one from one of the round suits.

Problem G:  3 !H  Is it asking for a stopper or a minor two-suiter?  The hints all include spades, so a simple cue might hit my two suits.  Otherwise, all I can think of is double and pull spades to clubs to show the other two suits.  Time enough to mull this a while longer.

Problem H:  !C 6  When partner bids, I like to respect the effort by leading the suit.  It also helps that the no-trumper is between my lead and partner's suit.  The safe lead feels like the !D K - the outstanding diamonds might be split 1-1 or 2-0, but it might be good to get rid of the ace early.

SOLUTIONS FOR:
James Creech

Fredericksburg VA 22407
U.S.A.

PROBLEM A: 5 Clubs  I don't see much chance for a slam, so I will holster the cue-bids and just bid the club game.

PROBLEM B: 1 Notrump  I am a maximum for my bidding, but then a minimum for my stopper.  I don't want to introduce a four-card suit, even at the one-level.  I will settle for my least of evils/ best of descriptions.

PROBLEM C: 2 Diamonds  I may be a bit heavy for my bid, but it is the best description.  I can tolerate partner's suit and I want to make a constructive move.  This satisfies those desires without going crazy.

PROBLEM D: 2 Spades  A nebulous cue-bid.  I want to show support, but leave room for more description.  This cue takes up the least space, and maybe I will hear something I like.

PROBLEM E: 4 Diamonds  To show shape or to cue-bid?  I think I will cue-bid rather than imply the shortness.  Since I hope to be slamming, I won't like bidding 4 !S and then hear pass.

PROBLEM F: 3 Spades  I am tempted to pass, but then is partner bidding out their shape or cue-bidding.  I'll retreat to our 4-4, and hopefully showing a hand that is weak.

PROBLEM G: 1 Diamond  I was tempted to bid 1 NT, but it feels bigger than its HCPs.  Also bidding 1 !D gives us a better shot to find a major, and deceptively discourages a diamond lead if I bid the NT.

PROBLEM H: Spade 8  I think the double is steering me away from the heart lead, but what should I lead?  I doubt that partner is ruffing clubs, but he might have the spade ace.  As the saying goes, I cannot have a singleton if I did not make it my opening lead.

On problem F, where we were asked to raise 1 heart or not raise it  with  KJx, Kxx, AKxxx,  98, ZIA's comment"If you don't know by now that this the winning bid, it's probably too late." infuriated me. Then I noticed  the 72% agreement from the panel which changed my mood to merely  'depressed'.  I have played about 400,000 bridge hands since 1963,  and raising hearts with this hand is not even on my  "let's have a little fun" list,  so I guess it's well and truly  too late for me :o

Blu, I too have not fully embraced raising on three. I rarely do it. And although I know Spiral and know 3344, I do not advertise it 'cuz my three card raises are so few and far between. When I do raise with three I generally limit them to when I have a stiff somewhere.

This panel result has me thinking that I need to rethink. Sigh . . .

I found Pratap Rajadhyaksha's comment the most illuminating: "Either one notrump or two hearts could be right for a partscore, but two hearts will encourage partner to look for game and shows a sound opening bid (as I could have passed one heart).  As many would have upgraded to a strong notrump, a one-notrump rebid seems a bit feeble." 

Personally, I would have opened 1 NT with this hand - two suits with tenaces, 14 HCP plus a five-bagger headed by the ace-king speaks volumes to me for an upgrade.  Having chosen to open 1 !D (perforce by MSC), the question is how to respond given that you are already bidding differently than you would like.  Rather than complain or scream misclick, you make the best of the situation.  Under those circumstances, 1NT sounds like an 11-13 with a poor heart fit, while 2 !H sounds like a 13-14 with a good heart fit.  Now the question is, can partner take a joke?  You have also promised four-card support, but have actually raised with less, assuming that the doubleton club with be a decent ruffing value in a possible Moysian fit.

Eric Kokish called this problem "A style tester.  The one-notrump bidders are following their systemic preference."  When I provided my answer, I did not think about the issues that Pratap raised, and just followed my original plan of rebidding 1 NT.  On reconsideration, I see that having made a bad initial choice, there is some need to try to catch up.  I only looked at the problem from my own holding, not how partner might be viewing my holding given my choices of bids.

As I said as commentator "Opening 1 NT solves, with this hand, so many problems off the top, that I cannot imagine having this problem at the table."  And that made all the difference.

May MSC SUMMARY (Part 3)– Bart Bramley, Director


Problem G  (c4) 1 ♣; then, after, (Pass) - 1 - (Pass) - ?, 2 (JCreech, BabsG, YleeXotee, Masse24, BluBayou, CCR3, VeredK)

Imps  Both sides vulnerable
You, South, hold:

♠ K 4 3    3    A Q 10 4   ♣ A K 6 4 3

SOUTH   WEST   NORTH   EAST
   ?         
What is your plan?

(a) 1 NT
(b) 1
(c) 1 ♣; then, after (Pass) - 1 - (Pass) - ?
    (c1) 1 ♠
    (c2) 1 NT
    (c3) 2 ♣
    (c4) 2
    (c5) 2 NT

The question raised by the moderator, Bart Bramley, was "Is this another 'style tester'?  The question before the panel was: 'Is this enough to reverse?'"

c4 (1 ♣; then, after, (Pass) - 1 - (Pass) - ?, 2 )   100   BWP 52%   BWS 59%  IAC 100%
The answer emerging from both the Panel and the solvers is "yes."  All three groups provided a majority for the reverse into diamonds, but other than IAC, the majority was joined by substantial minority positions.  BluBayou declares:  "The die has been cast! If we aren't reversing after partner's normal response, we shouldn't have opened one club."  But Jock, you cast the die for clubs; you had other openings available.  Mark Feldman admits to the sequence: "Having opened one club, I would be quite content to reverse."  Ross Grabel is "Not uneasy about this.  The hand has the values to open one club vs. one diamond."  Robert Wolff says to "Just bid naturally and recognize a minimum; natural has advantages."  Steve Beatty: "With a control-rich, five-loser 16-count and two reasonable suits, this is a model reverse."  Kit Woolsey: "With all these prime values, I'm willing to risk a reverse.  Sometimes the auction doesn't go as shown, and then it will have been best that I opened in my longest suit."  JCreech: "I see no reason to distort my shape.  I wish I had some better spot-cards, but this hand has primes, so I am willing to reverse on this 16."  Sartag Hans: "After half a lifetime of waiting for 'pure' six-four-type hands for reverses, I've joined the herd of 'show the strength and the basic shape with a five-four reverse.'"  JoAnna Stansby: "Short only a jack for an otherwise-perfect description, and the good controls everywhere make up for it."  Pratap Rajadhyaksha considers it "A bit light for a reverse, but I like the other alternatives less."  Kevin Rosenberg agrees "This is a bit light to reverse, but it is least of all evils."  Jeff Alexander: "Minimum.  Without the spade king, I'd open one diamond."  Joe Grue: "Hits the bottom of the reverse range."  Zia, though, says "This is a good 16-count.  I'm an optimist and will make a goodish approach.  The diamond ten is not chopped liver."  I like the point Masse24 makes: "The ugly reverse. Also strongly considered the 'if I can only get past this round' 1 !S. But the point shy reverse is the lesser lie. It also has the advantage of being more likely to get us to the right strain."

b (1 )   90   BWP 34%   BWS 23%  IAC No solvers
The most substantial alternative vote from the Panel, was to not reverse by distorting the shape of the hand; bid the four-card diamond suit first, so the five-card club suit could be shown without reversing.  Among the solvers, there were no IAC votes, but nearly a quarter of the BW solvers liked this approach.  Danny Kleinman considers the hand "Just a hair below the threshold for one club then two diamonds.  Add two black tens and I would say 'just a hair above.'"  David Berkowitz claims the gerontological excuse: "Too old to change now.  To open one club and not anticipate a one-heart response would be very shortsighted."  Mike Passell: "No auction looks promising after opening one club.  After one diamond - one heart - two clubs - two diamonds, I will upgrade to two notrump."  Don Stack asks "Will we miss game after a two club rebid?  Probably not.  As long as the shorter diamonds make a decent four-card suit, this usually works well."  Allan Graves: "I almost never prepare an auction in the minors, but when I have enough strength to bid around with a strong two-of-a-major raise and too little for a pushy reverse and the diamonds are decent, the I say okay."  Eric Kokish says "... I'd rather bid the long suits without admitting to reversing values."  Billy Eisenberg regards this approach "The least evil."  Augie Boehm writes:  "Without the wire, I might well open one club and hope for competition or a one-spade response that would elevate the hand into reverse territory."  Augie regards this problem as telegraphing what will happen, I think he is taking the wrong approach to the problem.  To me, the problem is anticipating the worst-case scenario, and trying to cater to the best solution.  That is Carl Hudecek's approach: "I prefer to solve a rebid problem early, so not one club.  Don't ask me what I would do if partner responds one spade."

c3 (1 ♣; then, after, (Pass) - 1 - (Pass) - ?, 2 ♣)   60   BWP 7%   BWS 6%  IAC No solvers
The third choice was to avoid the reverse by bidding and rebidding the clubs; a common approach understood to show an unbalanced hand that may not have a sixth club.  Hemant Lall thinks "With 16 HCP, I want partner to keep the bidding open over two clubs with 9-10 HCP.  I suspect he will have more hands with which to give a courtesy raise to three clubs if I open and rebid clubs than if I open one diamond and rebid two clubs.  Over three clubs, I will bid three notrump."  Jeff Rubens says "The advantage of (c) is that the single-most-likely scenario will often not occur.  (c3) is a guess with the excuse of demotion for the misfit and the absent sixth club."  The moderator points out that "We would bid the same way with 11 HCP and six clubs, right?  Sure partner may give those panelists another chance, but they're pretty much on their own, because North will never figure out what they hold.  And how will they reach diamonds opposite four or five of them?  Consider this North hand:  ♠ QJx    Axxx    Jxxxx   ♣ x.  Good luck!  They land in two clubs when six diamonds is on a finesse and normal splits."

c1 (1 ♣; then, after, (Pass) - 1 - (Pass) - ?, 1 ♠)   50   BWP 1 Panelist   BWS 6%  IAC No solvers
The fourth choice was too avoid the reverse by clearly distorting the shape; choosing to bid the spade fragment rather than upgrading the hand to a reverse, or suggesting a balanced hand by rebidding 1NT.  Phil Clayton is reluctant: "I don't love it, but I dislike the other options more.  If partner raises, I will have an easy two notrump.  If partner bids one notrump or two clubs, two diamonds will complete the picture."  The moderator commented "Unnecessarily bidding a three-card spade suit is the 'suicide bombing' option.  Two diamonds may complete a picture, but it's not a pretty one."

a (1 NT)   50   BWP 1 Panelist   BWS 1%  IAC No solvers
The fifth choice is a repudiation of the ACBL restriction of the opening of 1 NT with a small singleton.
Phillip Alder "I do not like this with a low singleton, but I strongly dislike opening one diamond, and the rebid problem after partner's one heart response is even worse."



Problem H  !D A  (None)

What is your opening lead?

You opened and partner was not helpful as the opponents ran roughshod over you to bid 3 NT.  LHO doubled and bid hearts.  RHO bid 1 !S when forced to respond, but jumped to 3 NT at his next opportunity.

In general, I would place RHO with spade length and club values, and LHO with extra strength and hearts.  Beyond that, the placing of values and length are in the minds of the opening leaders.

A   100   BWP 55%   BWS 26%  IAC No solvers
Hemant Lall feels "The best shot to beat the contract and not to give up a trick.  East is probably 4=2=3=4 or 4=2=2=5, and the diamond king rates to be in the dummy - maybe doubleton when partner has jack-fifth or -sixth.  Or, if king-third is in dummy, we may be able to set up partner's diamond and hope that he gets in with a heart."  Kit Woolsey believes "Our future might be in diamonds; but, since declarer appears to have at most four spades and three hearts, his future might be in diamonds.  By leading the ace, I can see the dummy and partner's signal, an those should tell me how to continue."  Steve Beatty goes for the last suit standing: "The other three suits look worse."  David Berkowitz: "LHO has hearts and a good hand.  RHO has the blacks.  Maybe that leaves partner with some diamonds.  Leading the ace, I can see what aI should have led at trick one."  Pratap Rajadhyaksha: "Must attack before the heart ace is dislodged. ... I lead the ace rather than the queen, because we may spear something at trick one, and it allows me to look at dummy.  A beat seems unlikely on the auction, but we may be able to stop some overtricks."  Carl Hudecek reminds us that "Partner couldn't bid over one club doubled, so he is probably broke.  I'm not optimistic about beating three notrump, so I take a look."  Zia finds it "A narrow choice between ace and queen.  I've seen bare kings and other friendly layouts."  Ross Grabel: "Preferable to the queen as I can see dummy and also get partner's reaction."  JoAnna Stansby may have the best reason identified: "Partner would have raised clubs in some fashion with five.  At least I'll get to see dummy and know what to do next." 

Q   90   BWP 34%   BWS 20%  IAC 57%
JCreech: "I hate to say this, but my strongest inclination right now is to lead the !D Q, like last month, hoping to hit Jxxxx with partner."  Masse24 is also "Hoping for length and a Jack from partner."  Kevin Rosenberg thinks "The queen might be more effective than the ace (maybe declarer will have king-ten-low and fail to duck when partner has jack-fifth).  It might have more deceptive value.  I'll be sorry if dummy has stiff king."  Phillip Alder: "If we can defeat the contract, this looks like the suit to lead.  If partner lacks the king, surely it will be in the West hand.  No other lead has any appeal."  Billy Eisenberg "At least as good as anything else and may produce a home run."  Allan Graves: "With no good lead, let's attack and force a duck with king-third to hold declarer to four."  Don Stack: "It appears that leading any other suit would produce tricks for the opponents."  While Mike Passell may have the best reason: "Looks like a time to be desparate."

♠ 2   60   BWP 7%   BWS 14%  1 solver
Phil Clayton feels "Any non-spade could easily blow a trick and would be too committal. ... North will be weak, so I am not too concerned about camouflaging my spade holding."  Augie Boehm: "It wouldn't be a great surprise to find partner with four spades, or at least three, since the opponents didn't bother to explore a spade fit."

4   50   BWP 1 Panelist   BWS 2%  IAC No solvers
Robert Wolff echos the uncertainty of his choice: "In the land of the blind, the one-eyed man is king; this opening lead belongs in that category."

♠ 9, 8   10   BWP No Panelists   BWS 30%  IAC 29%
About 30% of the solvers made this selection, but no Panelists.  Phil Clayton discussed why he did not choose a high spade to show his disinterest: "I cannot afford to lead the nine or eight and crash partner's two honors doubleton (or even honor-seven-doubleton)."

I feel Sami Kehela has the right idea: "Just an uneducated guess." regardless of what lead was chosen this month.


Meanwhile, this concludes this month's MSC summary.  I hope you found something interesting, or at least entertaining in this summary.  Please join next month's contest (and when you do, tell us why you chose what you chose - you may find yourself quoted in the next summary).

May MSC SUMMARY (Part 2)– Bart Bramley, Director



Problem D  Pass  (YleeXotee, BabsG, JCreech, Masse24, VeredK, CCR3)

What call do you make?

Partner's bidding on this hand indicates length in hearts and less than 9 HCPs.  So what do you do?  You have a good hand with stoppers in the unbids, so do you try to improve the contract, do you yield to the rules of misfit hands and pass, or, with a very nice six-bagger, insist on playing in diamonds?

Pass   100   BWP 66% BWS 53%  IAC 88%
The majority stance across the board is to pass. Pratap Rajadhyaksha asks "What's the problem?  Pard has shown 6-9 HCP with six-plus hearts.  With aces and kings, I put down the dummy."  David Berkowitz says "Even thinking would be an overbid; stay out of trouble if possible."  Allan Graves thinks "Partner should not have a good hand for three notrump."  Zia: "Sounds like three=six in the majors.  It may be prudent to exit stage left."  JCreech:  "Partner's bidding typically shows a weak hand with long hearts and no fit for my diamonds.  Time to quit trying for better."  Danny Kleinman reminds us that "The second-best place to play a misfit is usually in the long suit of the weaker partner."  The moderator, Bart Bramley, continues Danny's thought:  "...  the first-best place is on defense, but that ship has sailed."  JoAnna Stansby: "When each hand has a six-card suit, the suit headed by ace-king should come down in dummy."  Joe Grue points out "Partner is severely limited by failure to bid two hearts earlier."  Augie Boehm "North has described six weak hearts and limited values.  One-suit negative doubles are unpopular, but partner seems to have managed one."  YleeXotee:  "I went around in circles on this one. but finally as I had noticed in an aside, why wouldn't p bid 2h to start if they wanted to force. The error in my thinking was that 2h was a "new" suit. technically, its a rebid of the 4 hearts already shown."  Masse24 provides the final word:  "The law of Holes applies here. 'If you find yourself in a hole, stop digging.'"

2 NT   70   BWP 14%   BWS 29%  IAC 1 solver
Some show their side-suit stoppers.  Phil Clayton argues "Partner didn't bid three hearts initially so doesn't have seven.  If partner has a weak 3=1=6=3, he should have passed two diamonds. ♠ xx    AQxxxx    Qxx   ♣ xx is possible, and I am not giving up on three notrump, even though I am probably lookin for lightening in a bottle."  Eric Kokish: "Could get us to three clubs when we belong there, but in any event caters to everything except two hearts."  Jeff Rubens says "Having failed to bid one notrump, I am indicating six diamonds and fewer than four clubs, most likely 3=1=6=3.  I am underbidding the diamonds by the ten-nine, but there isn't room to do everything."  Kit Woolsey: "Partner should not have only long hearts.  Two notrump give a very good description."  Phil's vision holds the most promise in my mind, but I'm inclined to make the bid when I am looking for magic (against far superior opponents, or clearly down in a match), but should I really count on a diamond fit?.

3 ♣   60   BWP 7%   BWS 2%  IAC No solvers
Some bid the unshown suit.  Carl Hudecek expects "... partner to hold several cards in the minors."  Jeff Alexander thinks "Partner has either clubs or a decent hand."  The moderator has concerns:  "If partner has clubs, that makes one of us.  Raising the level to play in a tenuous three=four fit seems questionable."  Personally, I am worried that if I bid clubs, partner will pass, and I am playing in a 3=3 fit.

3    70   BWP 14%   BWS 13%  IAC No solvers
Some return to diamonds; the suit is better than advertised thus far.  Robert Wolff considers the bid "Dangerous, but percentage; somewhat dependent on partner's tendencies."  Sartag Hans: "With long hearts, many Norths tend to bid two hearts fairly light over one spade.  The chance of game is minuscule.  Playing in diamonds will protect the black kings and should be worth an extra trick at least."  Ross Grabel concludes:  "I'm not sure I see the problem here."




Problem E  1 NT (CCR3, VeredK, Masse24, JCreech, YleeXotee, BluBayou)

The moderator "... expected a three-way battle among one spade, one notrump, and two hearts; pass was not on my radar."

1 NT   100   BWP 69%   BWS 44%  IAC 86%
The runaway choice is what I would consider the standard response; three-card support and the lower end of a raise of partner's suit.  Sami Kehela: "Clear: (i) hearts too flimsy to raise, particularly in a weak hand; (ii) 4-3-3-3 distribution."  Don Stack: "Do not want partner to bid over a raise to two hearts.  I will bid two hearts over two of a minor.  If North tries three hearts, pass is probably correct."  Phillip Alder: "Throwing up a small smokescreen seems like a good idea."  Jeff Alexander: "Standard nowadays."  Ross Grabel: "The first order of business is to put the brakes on while allowing for partner to hold a near game-force."  Mike Passell: "Too weak for two hearts, one spade would be silly."  JoAnna Stansby: "Bidding two hearts will often push us too high."  David Berkowitz: "Not enough for a modern two hearts, and I'm certainly not bidding the robust spade suit."  Similarly, JCreech says "Without a ruffing value, I don't see a good reason to raise the hearts directly.  With crappy spades, I will not bid 1 !S; I don't want to encourage partner to re-evaluate any spade holding."  Kit Woolsey: "A raise might encourage partner to drive too high.  If North passes one notrump, that might be as good a spot as two hearts."  Joe Grue: "Too weak to raise with three low; maybe I'd raise with king-jack-third."  Phil Clayton: "I cannot bring myself to raise on this dreck.  If partner passes, I will be happy to play for seven tricks instead of eight."  Augie Boehm: "Too strong to pass, too weak to raise.  If our auction dies at two hearts, the opponents may be reluctant to balance, since they will likely assume that we lack a true heart fit."  BluBayuou describes this differently:  "TEN  LTC "LOOSERS"? Surely it is time to trot out the "cheating raise"---via semiforcing 1NT + plus heart preference.  Obviously BWS doesn't use constructive raises or this would be a quizz with exactly ONE answer"  However, Masse24 clarifies the nature of direct raises:  "Follows system (Constructive raises). The four-card spade suit is a red herring. The thing that concerns me is that two or three 1 !S responses will dilute the 1NT responses. I’m also concerned that a handful of panelists will eschew the system in favor of the preemptive value of 2 !H."

Two Panelists choose to support with support.  Robert Wolff says "Again very close vs. pass; I choose aggressive."  While Arthur Robinson reminisces:  "I lasted 10 years with Bob Jordan by raising him." 

Pass   80   BWP 24%   BWS 3%  IAC No solvers
Although it is hard to envision in this world of light openings and aggressive action that experts would think to pass 6 HCPs and three-card support, it is not crazy.  Old-time valuations, would have subtracted a point based on the 4=3=3=3 shape and the KnR for this hand is even less (4.3).  IAC did not vote this way, so let's see the arguments posed.  Allan Graves points out that "The auction isn't over and rates to be below two hearts on the next round."  Jeff Rubens: "Out of fashion, but in the modern game there is too much focus on high-card points to the exclusion of quality of support, nature of honors, and shape."  Mark Feldman feels that "At this vulnerability, there is no reason to bid."  Billy Eisenberg: "Maybe it's close."  Carl Hudecek thinks there is "Not enough stuff to raise."  Danny Kleinman says the "Flat shape and weak three-card support put this hand below the normal threshold for a raise; if the queen were in hearts, I would eke out one."  Hemant Lall choice is conditional:  "Matchpoints, I pass.  As both opponents have passed, if I bid partner may drive to a game likely to fail."


1 ♠   30   BWP No Panelists   BWS 13%  IAC No solvers
What about the spade suit?  You hold four, and you want to avoid the direct heart raise, that sounds like a reason to bid the spades.  No one on the Panel bit, though some discussed the option while choosing to bid 1 NT.  Kevin Rosenberg says "Generally, I respond one notrump rather than one spade with three hearts in a hand too weak to raise (especially with four weak spades).  Eric Kokish: "North might raise one spade with three, so I'll steer toward two hearts modestly."  Steve Beatty: "Even if partner has four spades, one spade may not work out with my poor spade holding and secondary honors in partner's short suits."  Pratap Rajadhyaksha: "I don't want to bid one spade lest pard raise with three.  Another ad for Flannery, Bart?"  CAUTIONnone of the above opinions were in support of 1 !S as a response, the discussion was entirely why 1 !S was not a good choice.




Problem F  2 !H (BabsG)

Matchpoints  East-West vulnerable
You, South, hold:

What call do you make?

You opened 1 !D, [partner is a passed hand and responded 1 !H,  so what is the best description of your hand?  You are semi-balanced, so 1 NT is a possibility; your have three-card support and a ruffing value, so 2 !H is also a possibility; and you also have a 14 count that could be promising, or maybe not, so perhaps passing partner might be the way to go.

The Panel was heavily invested in raising with only three, though there was also a substantial minority of BW solvers that joined in as well.  Kit Woolsey describes the hand as "A bit too strong to pass and suit-oriented enough to prefer two hearts to one notrump."  Phil Clayton considers the bid "Fairly automatic with a weak doubleton club and values that mostly aren't positional.  I agree with one diamond at matchpoints, although I would have opened one notrump at imps."  Hemant Lall: "The best shot to find the right strain and level, especially important in matchpoints."  Don Stack:  "This is the only type of balanced hand that should offer a three-card raise:  A worthless doubleton and three trumps headed by an honor.  This will not play terribly even opposite four low cards - or will it?"  Ross Grabel "Three strong trumps and shortness in a side suit, although I wish the clubs and spades were reversed."  Jeff Rubens: "Habits of a lifetime."  Pratap Rajadhyaksha "Either one notrump or two hearts could be right for a partscore, but two hearts will encourage partner to look for game and shows a sound opening bid (as I could have passed one heart).  As many would have upgraded to a strong notrump, a one-notrump rebid seems a bit feeble."  I must admit that I was not thinking about how a NT rebid might sound to a passed-hand partner in the face of third-seat upgrades to a strong NT opener, despite the fact that I would have opened 1NT at the table.  Billy Eisenberg: "More encouraging and forward-going than one notrump."  Sartaj Hans thinks "We might easily make a game in hearts, so I must encourage partner to act aggressively with five hearts."  Eric Kokish views it as "A style tester.  The one-notrump bidders are following their systemic preference."  As Sami Kehela begs the BW staff: "Please provide us with more such problems instead of torturing us.Zia, though, provides the final zinger: "If you don't know by now that this the winning bid, it's probably too late."

1 NT   70   BWP 17%   BWS 57%  IAC 86%
Majorities of the IAC and the BW solver votes went with 1 NT.  It certainly shows the shape and describes the hand, if partner were not a passed hand.  Mike Passell says "I can't think of an alternative."  David Berkowitz follows his original plan: "I have a weak notrump, so I show it.  I would have opened one notrump had partner not been a passed hand."  Augie Boehm: "Either pass or two hearts would be too committal.  Opposite a sound opener, game is still a lively option."  BluBayou sounds like he agrees:  "Maybe MAYBE I could raise one SPADE to two, but  not one heart."  Kevin Rosenberg, clearly does not like the original choice, but follows his style: "I would have opened one notrump.  I don't raise on a balanced hand with three-card support."  JCreech:  "I am torn between 1 NT, raise partner and pass.  I am minimum opposite a passed hand, but I also have a maximum, full-values for my minimum.  I do not want to encourage the opponents to enter the fray with the pass, and I don't want to encourage partner too much with a raise (particularly if he only has four), so I split the difference with the very descriptive 1 NT."

Pass   60   BWP 10%   BWS 3%  IAC No solvers
Some think it is right to bail with a balanced minimum opposite a passed hand.  Carl Hudecek "If partner were not a passed hand, I would raise to two; here, I want to avoid one notrump with good heart support and two low clubs."  JoAnna Stansby is "Planning to bid two hearts if the opponents balance." 


I don't often comment on the problem; you take the problem as it is presented and make your decision.  But then I think it is right to open this hand 1 NT in third seat (and much of the time in any seat).  Although I did not calculate the KnR until this write-up, it is 14.95; how much better do you want the hand to be for an upgrade?  Joe Grue makes a good point:  "I would not have opened one diamond with this nice 14-HCP hand unless my range were 16-18 HCP or 12-14 HCP."  Opening 1 NT solves, with this hand, so many problems off the top, that I cannot imagine having this problem at the table.  Masse24 echos the thought:  "Why didn’t I open 1NT?"



This concludes Part 2.  One more to go, and I will get to it when I have time.  Hope you are finding the discussion useful, and please do not avoid participating in next month's problems.  We love to see the regulars, the return of old friends (KenBerg, we see you lurking), and the addition of new ones.  Please join in the fun.

May MSC SUMMARY (Part 1)– Bart Bramley, Director

Problem A  3 !H  (Masse24, JCreech, BabsG, YleeXotee, BluBayou, CCR3, VeredK)

Imps  Both sides vulnerable
You, South, hold:

♠ A J    Q 9 8 6 4 3    Q J 7   ♣ A 8

SOUTH   WEST   NORTH   EAST
  ——      ——      ——       1 ♣
  1        1 ♠        2        Double*
   ?         
*three spades

What call do you make?

With 14 HCPs and six hearts, you have a nice hand, but your primes are in short suits, and you have soft values in the diamonds.  How good is your hand, really?  At the table, given that it is imps, I might try bidding game, gambling that partner's values are working in concert with mine.  But this is MSC, so thinking through the strengths and weaknesses of the hand are important.  Everyone is bidding, which lends itself to a partscore and competing, but the right values from partner could make game a laydown, which suggests making a game try.

3    100   Bridge World Panel (BWP) 34%   Bridge World solvers (BWS) 59%  Intermediate-Advanced Club (IAC) 100%
IAC is all in with 3 !H, while the BW solvers make it their majority choice and the Panel, their plurality choice.  Most view this action as purely a competive action.  Masse24 thinks to "Jam their auction. Unanimous?" but his prediction only works for the IAC solvers.  Kit Woolsey: "I will want to compete to three hearts, and this isn't worth a game-try, so I don't see Plan B."  Jeff Rubens is "Hoping to profit from unresolved ambiguities in the East-West bidding."  Billy Eisenberg: "Bidding my limit before the opponents have a chance to discover what they can make."  Ross Grabell: "To make it uncomfortable fot he other side to compete."  Pratap Rajadhyaksha thinks "I will need to bid this eventually, so I might as well impede the opponents.  Game is remote with flat shape, slow values, and no cue-bid from partner."  Kevin Rosenberg struggled:  "Almost all the decent games I can construct give North a hnd worth a cue-bid."  I agree with JoAnna Stansby: "Too many losers for a game try."  Resulting in Sartaj Hans' observation: "After a game-try, North would too often accept when game has no play.  Three hearts will miss some close games but avoid a lot of hopeless contracts."  Danny Kleinman: "Just enough extra to have hope for game.  In-and-Out valuation and all that jazz."  Taking a simplistic view, BluBayou "Binary choice!  -- Follow the LAW, and reraise or don't do so and let 2 !S ride and likely buy it.  Right now, count me IN ..."  While JCreech responded: "I don't know where Jock gets off thinking there are only two options, I can see two cue-bids available for the aggressive, in addition to the two he identified.  Would I choose one of the cue-bids?  Probably not.  Are they unreasonable?  No.  You only need nine HCPs from partner to have a reasonable shot at the heart game (less with the unlikely singleton or void in diamonds).  Nonetheless, I find solice in the LAW.  Pass is too weak and the cue-bid too strong, while 3 !H is just right."

Pass   60   BWP 7%   BWS 7%  IAC No solvers
Those passing have given up on game entirely, but not necessarily competing.  Arguing for the wait-and-see approach, Augie Boehm says "The heart tricks seem too slow for notrump.  I'll listen before deciding about competing to three hearts; our nine-card heart fit lacks ruffing potential."  Carl Hudecek writes "If two spades comes around, I'll bid three hearts; but game looks hopeless, and freely bidding three hearts would be forward going."  However, Carl's view of 3 !H seems old fashioned.

2 NT   70   BWP 10%   BWS 1% IAC No solvers
Showing their black-suit stoppers and offering an alternative strain are the two notrump bidders.  Does it hurt to put partner on notice that a double of 3 !S may be the best place to play this hand?  Phil Clayton feels the "Game is too likely merely to reraise."  Hemant Lall points out that "Partner can have useful cards in all four suits; two notrump puts that message across."  While Eric Kokish feels that "It will be good to be able to double three spades with partner involved.  A redouble would be too much, pass or three hearts too little."

3    80   BWP 21%   BWS 12% IAC No solvers
Some viewed 3 !D as the best game-try alternative.  Phillip Alder thinks the bid: "On the aggressive side, but we are vulnerable at imps."  Allan Graves: "Usually, partner will not be strong enough to bid more than three hearts.  If the opponents bid on, a diamond lead from the king would be good."  David Berkowitz says to " Announce that we own the deal before things get out of hand.  If we sell to three spades, so be it."  Steve Beatty feels he "Can't redouble with an extra heart and secondary honors in long suits.  Vulnerable at imps, partnerships usually invite aggressively and accept conservatively so maybe we won't get too high."  The moderator, Bart Bramley, points out that "The trouble with three diamonds is that it is misdescriptive, implying a two-suiter, or at least a suit-oriented hand.  Partner, with a top card in each red suit, will often drive to game when there is no play."  I'm not so sure about all of Bart's analysis, but the hand is versatile - aces and heart length for a suit contract, as well as QJx of diamonds, AJ of spades and values in all suits suitable for notrump.

Redouble   90   BWP 21%   BWS 10% IAC No solvers
For me, the problem with 3 !D was that it put the focus on only diamonds, when I would also like to know something of trump quality; it was too one-dimensional.  An alternative is redouble, and if I were inclined to make a game try, I think redouble is the one I would make.  Robert Wolff describes it as "Informing partner that I have an excellent overcall, just under the values for bidding game."  Similarly, Mike Passell says "To involve partner.  If he starts doubling, I will be happy."  Sami Kehela: "Strong hand; general values."  Jeff Alexander: "To convey that this may be our deal (against today's light openings and responses).  We might have game opposite a couple of kings and a queen."  Joe Grue sums it up nicely: "To make it possible to find game; three diamonds is not what the hand is about. Three notrump is far more likely than four hearts to be our game, and I will be happy if we buy the contract in three hearts."




Problem B  3 !H  (VeredK, CCR3, Blubayou, YleeXotee, BabsG, JCreech, Masse24)

Imps  East-West vulnerable
You, South, hold:

♠ J 10 9 7 2    9 6 3 2    10 7 3 2   ♣ —

SOUTH   WEST   NORTH   EAST
  ——      ——       1          1 ♠
   ?         
What call do you make?

You have length in both partner's and RHO's suits, the opponents are vulnerable while you are not, and you have 1 HCP and a void.  Does this give you the liberty to mess with what appears to be the opponent's auction?

Pass   70   BWP 14%   BWS 15% IAC No solvers
There were naysayers.  Danny Kleinman: "Ain't go nothin' but shape, and for all I know partner may have lots of stuff in clubs.  No reason to try to obstruct opponents who may be headed for spades."  Jeff Rubens: "Current biggest worry is partner; I don't want North to think that I have or might have high-card values."  Allan Graves: "I don't want to encourage partner to bid except voluntarily.  North should allow for this hand if short in spades."  This call describes your HCPs, but little else; there is a lot of playing strength in that one measly point.

2    60   BWP 7%   BWS 8% IAC No solvers
Chiming in timidly.  Robert Wolff says "If I do not support now, I'm likely to regret it later."  Sami Kehela is "Joining in, against my better nature."  What I don't like about this bid is that partner will expect values, not shape, which can turn into wrong expectations later.

3    100   BWP 55%   BWS 60%  IAC 100%
Another IAC unanimous vote, coupled this time with majorities from both the Bridge World Panel and solvers.  BluBayou writes: "A favorite quote i heard long ago goes 'If your weak jump raises don't terrify you a bit, you're not doing them right.'  If you combine the votes for 'pass', 2 !H  and 4 !H  together, the panel should still be at 21-6  or something in favor of the jump-raise ..."  Phil Clayton "Gives our opponents just enough rope without hanging partner.  Steve Beaty think it is "Right on playing strength and forces East-West to begin looking for a minor at the four-level."  Zia: "Should be enough.  Should be enough.  Four would be a bit over the top, and there is no reason to thing that the opponents' clubs are not breaking badly."  Joe Grue: "I'm content trying to stop the opponents from reaching three notrump easily."  Mike Passell says: "Perfect hand.  Makes it difficult to find a fit, which is a good idea."  Kit Woolsey describes the bid as a "Classic preempt to the level I think we should compete.  If partner bids game, I might or might not have the right cards, but there is no way to find out.  JCreech: "The LAW guides me ... Let's get to our proper level as quickly as possible.  This may result in the opponents continuing to imprudently bidding spades, but it will also make it more difficult for the opponents to find an alternative strain."  Kevin Rosenberg: "Too attractive to resist."  Phillip Alder: "No doubt there will be four-heart bidders influenced by the void."  Masse24: "I was all over the place on this one. Considered 2 !H and 4 !H too. But 4 !H was too hot. And 2 !H was too cold. 3 !H was juuuuust right."

4    90   BWP 24%   BWS 17% IAC No solvers
Going for the gusto, some bid game directly.  Joanna Stansby is "Counting my void plus the vulnerability as a fifth trump.  The opponents will have problems finding their best spot."  David Berkowitz: "Do not know who can make what, but I won't wait to find out.  Maybe I can coax an injudicious four spades out of the opponents, or maybe I can keep them out of clubs.  It won't always go double all pass."  Eric Kokish says "One either believes a jump-raise is acceptable or worries about doing too much if the opponents complete."  Sartag Hans: "Hands with voids and a fit play exceptionally well.  Nonvulnerability increase our downside protection.  The opponents' vulnerability provides an extra edge in the hope they misjudge."  Hemant Lall argues that the bid is "Better than three, because it gives the opponents less room to explore.  On a good day, they will double four hearts, and partner may make it with as little as: ♠ x    AKxxxx    Axx   ♣ xxx, for a double-game swing.  Also, we may beat four spades when five clubs is cold."  Pratap Rajadhyaksha: "The book bid is probably three hearts, but that would allow West to double, perhaps enabling the opponents to get together in clubs.  I am reasonably confident that partner can take at least seven tricks and prefer to force the opponents to make the last guess when possible."  Roy Welland: "Overbidding as usual."






Problem C  4 !D  (BluBayou, CCR3, Masse24, BabsG)

Imps  Neither side vulnerable
You, South, hold:

♠ K 6 5 3 2    7 3 2    K J 10 7 5   ♣ —

SOUTH   WEST   NORTH   EAST
  Pass      1 ♣        2 ♠        3 ♣
   ?         
What call do you make?

Another big fit, but a better hand.  Again, there are multiple ways to describe the hand, but much depends on how optimistic you are. And BTW, the opponents have already established a fit.
 
3 ♠   50   BWP 7%   BWS 4% IAC No solvers
A simple raise doesn't strike me as doing much.  It doesn't describe the big fit, it doesn't explore whether there is a double fit, and it doesn't obstruct the opponents much.  As a top choice, it feels more like a cow flop.  Jeff Rubens: "I don't see how giving partner information rates to help:  He can't be short in hearts and is not likely to be void of clubs, so he won't turn up with a boatload of diamonds."  Working toward life balance, Roy Welland says this time:  "Maybe underbidding could work sometimes."

4 ♠   80   BWP 24%   BWS 55%  IAC 43%
4 !S wold be the classic preemptive strategy.  You bid to your side's maximum level immediately and leave the opponents the last guess.  Danny Kleinman writes "I have no idea who can make what.  The opponents might have no idea either.  Let them guess at the five-level, and let them guess now."  Phillip Alder: "I usually like to make a fit-showing jump in this position, but that would give extra wiggle room to the opponents."  Robert Wolff: "Yes, I'm underplaying the offensive potential but, at this moment, I need to show support and await further developments."  Jeff Alexander asks "Where are the hearts?  I'll defend against five clubs, since five spades may be too expensive."  Hemant Lall: "The alternative is four diamonds, but giving descriptive information will help the opponents more than partner."  JCreech: "I typically like to blast to the level I want to be at immediately.  I may come to regret not bidding to the implied level of the LAW, but the 5-level is frequently daunting.  I will gamble that game will suffice."  JoAnna Stansby says "Partner's preempt can be a poker bid opposite a passed hand.  If I were unpassed, I would bid five spades to take away a key-card ask."  Augie Boehm: "I may have a guess over five clubs, but sometimes four spades will buy the contract."  YleeXotee is "wondering a bit about system, and Todd makes an argument for the fit jump. but over a weak overcall? I like 4S as the simple answer, but what will I do over 5c??"

3    70   BWP 21%   BWS 11% IAC No solvers
Partner only overcalled, but sometimes overcalls can be quite good.  Bidding diamonds should show spade support, but how high should you be bidding the diamonds, if you do.  Carl Hudecek is "Preparing a defense if the opponents by the contract.  I will keep raising spades to the four-level, then leave the rest to partner."  Allan Graves: "I would like diamonds led when the smoke clears."  Don Stack: "Do not want to bid four spades and push the opponents into five clubs.  If the bidding  ends at three diamonds, we will have stolen the deal."  Sami Kehela feels the bid "Necessary, although the possibility exists that I may not make it."

4    100   BWP 48%   BWS 18%  IAC 57%
As Masse24 pointed out "'Over a bid by responder, a jump, below-game, new-suit advance is a fit-jump.' Should aid partner if a 5-level decision must be made."  Similarly, Kevin Rosenberg "This might help our partnership judge whether to bid on over five or six clubs.  I plan to bid five spades if partner passes a five-level decision to me.  Bid more with voids generally; here, it's especially important to bid four diamonds so that partner can judge to bid six spades later."  Zia: "We may need to make a solo judgment later, breaking discipline."  Sartaj Hans is "Hoping to encourage partner to bid when we have a double fit."  Steve Beatty says "I hope that partner guesses my intentions correctly.  I want to bid five spades, but I am willing to give up pressure to suggest the lead if we are outbid.  Four diamonds might push us to a good slam on some days."  Billy Eisenberg describes the bid: "Lead directing, showing spades and diamonds."  Pratap Rajadhyaksha: "Directs the lead without committing to the five-level.  Pard can be relatively wide-ranging opposite a passed hand and will be able to make an intelligent decision."  Mark Feldman: "Opposite a passed hand, partner's possible holdings are numerous, and a fit-showing jump is not primarily lead-directing."  Ross Grabel thinks it "May help in getting the best lead or in guaging how high to compete."  Kit Woolsey: "Slam isn't in the picture.  If the opponents bid over four spades, I can hope that partner will know what to do."  Phil Clayton: "Partner probably has at least three hearts, so our high-level prospects are poor, and I do not expect to compete to the five-level.  However, a diamond lead might be the key to beating five clubs ..."  Joe Grue: "Partner can have a decent hand (opening strength is possible).  I want to stress that I have a ton of shape and big fit, so North can be in charge of competing.  I also want a diamond lead."  BluBayou "If we were not a passed hand, any number of spades from 3 to 6 --  plus 3 or 4 Diamonds would be in the running, but it would be presumptuous to imagine that the opps have a club or heart slam when partner jumps in 3rd seat.  Let's give what I hope is taken as a fit-jump and be glad we don't have a follow-up about what to bid on round 3."


This ends Part 1 of the May MSC summary.  I will return as time permits.  I hope you find something useful here, and will take some time to participate in the June problem set (now open on a different thread).

April MSC SUMMARY (Part 3)– Kit Woolsey, Director


Problem G  3 !H  (VeeRee, CCR3, YleeXotee, BluBayou, VeredK, WackoJack, JCreech, Masse24)

What call do you make?

You have shown your 5=5 in the minors, while partner has shown hearts. game-forcing values, and what may be reluctant preference for one of your suits.  You have to make a bid, but what to the choices mean at this stage in the auction?
 
3    100   BWP 54%   BWS 55% IAC 73%
A majority of both Panelists and solvers went with 3 !H.  Some clearly were wearing their rose-colored glasses; considering the 3 !D preference as more than a reluctant choice.  Danny Kleinman says "The sky's the limit.  Six diamonds is tempting but would be premature.  I hope that partner will know how confused I will be if he control-bids three spades with anything but the ace."  David Berkowitz thinks "With a beauty for diamonds, I will continue in that direction unless North bids three notrump, which I can comfortably pass."  Eric Stoltz: "Leaves in easy opportunity for partner to show spade values."  Masse24 "Control. At least that's how I intend it. I hope it's not taken as !H Hx."  CCR3 "How convenient. Cue bid next suit up the line with this 2 suiter. Slam possible."  WackoJack "Control agreeing diamonds.  It cannot be natural support"  The moderator, Kit Woolsey, asks "Why has partner shown great diamond support?  What if he is punting to get more information?  Suppose North holds, e.g.:  ♠ Qxx    K10xxxx    Ax   ♣ Kx and was reluctant to bid three hearts for fear of being raised on a singleton honor.  He can't bid higher than three diamonds to find out whether or not South has a doubleton heart."  Others show more caution.  Nik Demirev thinks "My job is to show the better major (breaking ties up the line) to evaluate if three notrump is playable."  John Diamond:  "Temporarily ambiguous but sufficient for now."  Zach Grossack is "Bidding where I live.  Opposite a diamond fit, this is a slam-positive holding, so I will show something useful in hearts."  Steve Robinson:  "Shows a heart control and denies a spade control.  I need a spade control for slam."  Or a softer spade control, such as Qxx or better, for 3 NT.  Daniel Korbel "Does not show a singleton spade."  Larry Robbins:  "Need not show two hearts, just a grope for the best strain, especially to investigate three notrump.  Three spades would indicate something in spades."  DickHy "We’re lacking a spade stop otherwise partner, who seems to have five hearts, would have bid 3N over 3 !C.  With two useless spades I’m hesitant about raising the temperature with a heart cue bid.  However, could North have Ax KQxxx Axxx Qx, having rejecting Ax as a stop?  Neither East nor West made a 1 !S overcall (one might hold Kxxx and the other Qxxxx), which seems to place North with a high spade honour.  3 !H would give North a chance to show Ax in spades (he won’t cue with Kx in spades), so perhaps it’s worth the detour, just in case 6 !D is on the horizon."  JCreech "Bid my outside control, and hope that nine-trick game is a viable alternative.  I really want to bid 4 !C to continue shape description, but decided to keep 3 NT available"  YleeXotee "flipping coins on this one too. I really thought about 4h. but 3h has to be ok too as control showing, I already did not show three hearts I think, but not supporting after the 2s bid. 3s is tempting too, but I couldn't talk myself into that one being a panel bid."  BluBayou "show  !H A--'nuff said."

3 ♠   90   BWP 36%   BWS 23% IAC  1 solver
Avoiding the appearance of finality of a 3 NT bid, some choose 3 !S as a mark-time bid.  Brian Glubok thinks it "The only punt available.  Three hearts would show a doubleton."  Carl Hudecek feels his bid "Suggests 3=0=5=5, but I want to try to reach a diamond slam, so three notrump instead would be too final."  Billy Eisenberg: "As we are below three notrump, this asks for a stopper."  Zia: "A fragment in BWS style."  Howard Weinstein says "I have significant extras, but not enough to force to slam or to commit to diamonds.  I will suggest my shape and hope for guidance.  I will pass three notrump or try hard for slam after anything else."  Bart Branley points out that this is the "Last chance for three notrump.  Three hearts should show at least two."  But I fear that Robert Wolff's assessment is most apt:  "Nothing else fits, so I invite partner to make the mistake."

Phillip Alder chooses to spurn the chance for NT and distorts his shape at the same time:  "The good news is nice trumps and two aces, the bad news is weak clubs and two spade losers.  I try to convey that message."  The moderator's opinion is the bid actually conveys "The message that partner will receive is that one of your low spades is a low diamond."  Hoki "would love to bid 4 as a control bid, but is it?"

Other panelists also spurn the chance for NT, but distorts the shape differently.  Rozanne and Bill Pollack:  "We will have an easy four hearts over four diamonds.  Our intermediates are nonexistent, but the good prime cards cover us."  Karen McCallum rejects all the other choices:  "A heart bid would suggest honor-low.  Three spades would become a control bid when I remove three notrump.  Four diamonds would squeeze the auction.  Four clubs allows four diamonds - four hearts"

What call do you make?

Got intrigued with Jock's comment, and now I see what he means.  You gave up the simple description on the first round of bidding due to only a partial stopper.  Now you have to decide between a cue-bid, that I think is a bit strong given five black losers, a raise with only three pieces, when partner could only have four, and bidding the diamonds and hoping that if hearts are right, partner will rebid them (or that you will get a chance to show the support later).

Right now, I am definitely headed toward a red-suit bid, but which one?  My inclination is toward the hearts.  I may not be happy ruffing a club with the jack, but it is better than ruffing with the queen (and maybe partner has the queen).

Problem D - I am likely wrong here, but I don't think 2h is passable. X and then a new suit. if p and I are misfit, they should have passed 2d. They must have X to show hearts, but have a bigger hand with at least 5+ hearts after all. I feel like I have system questions all over this month. I am considering 2nt and 3nt straight out.  (but then again, 2h straight out should be forcing for at least one round, so why choose the X route)


I may have knee-jerked a bit here.  Unless I am playing negative free-bids, a negative double followed by a new suit typically shows a long suit with less than a game-forcing hand.  I did not put it into the context of imps and that with a misfit, partner should have bailed first.  Nonetheless, what is partner doing?  Despite Joe's declaration that "...I don't think 2h is passable," I still think it is, or partner would have chosen a different route to describe his hand.  2 !H may be invitational, it may be descriptive, but it is definitely unclear within partnership understandings.  I am now asking myself if I should take another bid, and if so, which one.

April MSC SUMMARY (Part 2)– Kit Woolsey, Director



Problem D  2 !S  (Veredk, VeeRee, CCR3, BluBayou, YleeXotee, WackoJack, BabsG)

Imps  North-South vulnerable
You, South, hold:

♠ 2    A 9 8 5 2    A 6 4 3 2   ♣ A 4

SOUTH   WEST   NORTH   EAST
  ——      ——      Pass      1 ♠
   ?*         
*BWS: 2 ♠ = hearts and a minor; any biddable strength

What call do you make?

The opponents have opened, you are red and they are not, and you have a two-suiter with 12 HCPs all in aces and spaces.  And by-the-way, the opponents bid spades, which raises the level automatically if you decide to act.  Bridge is fun, right?

Pass   60   BWP 11%   BWS 12% IAC 1 solver
The easiest action is inaction.  Despite substantil distribution, the spot cards are largely horrible.  So you can pass to say this hand is not worth taking direct action.  Besides, maybe the opponents will also bid clubs, to make finding a fit easier.  Danny Kleinman point to "Thin suits and adverse vulnerability induce me to pass, but if I could unambiguously show hearts and diamonds (say with a cue-bid), I would.  Mark Cohen: "I hope to be able to compete later.  A cue-bid would commit you to the three-level opposite a passed North hand.  After two hearts - (pass) - pass - (double), I'd feel nauseous."  DickHy thinks "At best this is a 20/20 hand and I love my partner.  I’m not gonna dump him at the 3-level in a (ropey) 5 – 3 (probably 2 knowing my luck) fit with an emaciated hand.  Especially when red v white.  Besides, I don’t know how the spades are distributed yet."

Double   70   BWP 14%   BWS 8% IAC 27%
To compete at a lower level, you could double and hope that partner does not bid clubs.  John Diamond is willing: "Only if we are unlucky enough to land in a four-two club fit does this rate to work out very poorly."  Rozanne and Bill Pollack think "Two spades could produce a phone number.  We chickens say its not worth the risk.  Two hearts would be easier to nail.  Double hides the fifth heart (although we sort of have only four), but it keeps us at a lower level, and safety is paramount here."  Hoki "and pass 2♣ which I doubt will be left in (but can bid 2♦ if doubled?)"  Finn Kolesnik: "At unfavorable vulnerability with a weak suit, overcalling two hearts is very unattractive.  Two spades requires slightly better suits.  Double is least descriptive but safer and more flexible.  I won't cry if partner bids clubs; and when we have no big fit, the opponents will probably out-compete us."  Masse24 feels the bid is "A bit out there but it's flexible. I have the values, but that's all. And I'm only short one club. We're vulnerable and overcalling at the two level on an Ace-empty suit is not my choice. Same with pushing us to the three-level with nothing but shape."  Larry Robbins says "The long suits are a bit anemic for a vulnerable cue-bid.  Two hearts should be based on a six or a strong five."  JCreech "This vulnerability scares me to force us to the three-level.  I hope partner will treat this as an equal-level conversion if I pull clubs to diamonds."


2    80   BWP 25%   BWS 12% IAC No solvers
It seems like the best reason to overcall is that it is a safer action. As Fred Stewart describes it:  "Can't pass, a double would bury the heart suit, and two spades would be too rich."  Billy Eisenberg is pithy:  "Reluctantly."  Brian Glubok: "I prefer to keep the diamonds in reserve, perhaps LHO has a lot of them and wants to bid the suit."  Eric Kokish: "Ugly, so a cue-bid might be the right idea.  If there were an easy way into the auction later, I could understand a pass."  Daniel Korbel says "The hand does not justify driving to the three-level.  Even two hearts is in considerable jeopardy.  With both minors, partner can double two or three spades."  Robert Wolff thinks "The intermediates are too shabby to drive to the three-level, although if it went two spades back to me, I would probably bid three diamonds."

2 ♠   100   BWP 50%   BWS 68% IAC 64%
Despite all of the defects of the hand and the fact that the two-suit takeout is ambiguous regarding the second suit, the Panel and solvers both prefer the cue-bid to other options.  BluBayou writes: "This bucket of loosers  is what Michaels' cue was meant for, IMO.  Hoping to bid 2 suits one at a time is a poster child for  "making the last mistake".  MAKE them catch you after a SINGLE intervention if they can.  Remind your partner that the bid that means "show my your minor"  is TWO NOTRUMP,  not three clubs; Then it's possible  to come to a safe port,  should he mave 6+ clubs without any red support"  Bart Bramley: "I'm a big believer in showing two-suiters wholesale.  If LHO is about to bid a lot of spades, I'll be happy with my choice.  Two hearts would overstate the suit.  If LHO bids three or four spades, I'll risk a double."  Steve Robinson says "Find the fit first and worry about level later."    YleeXotee is "not passing up a hint, plus its what I would really do at the table"  To John Carruthers its "Like opening one notrump, we ought to do this whenever possible.  Here no other call is more descriptive."  Karen McCallum: "After decades of looking for (and not finding) reasons not to use two-suited bids, I'm back to telling partner about 10 cards in my hand whenever I can."  David Berkowitz: "This hand is not about hearts only."  WackoJack: "No other bid"  Zach Grossack: "Even for someone who is conservative regarding vulnerable, two-suited overcalls, this hand is too strong to pass, and other actions would be distortions."  Nik Demirev thinks "Acting immediately has competitive advantages if the opponents reach three spades or higher quickly."  Howard Weinstein: "Poor texture could lead to a disaster, but it is important to get both suits involved whenever possible."  CCR3: "Reluctantly. Toiled over this one. Could be right just as well as in deep trouble."  Or as Sami Kehela writes, "Don't blame me if we concede a large penalty."  Phillip Alder: "Even with the dice loaded against this action."  And Zia has his battle cry: "Purity be damned!  I want to win."




Problem E  2 !C  (BabsG, VeeRee, JCreech, Hoki, CCR3, Masse24, WackoJack, VeredsK, YleeXotee, Blubayou)

What call do you make?

You have opened and bid two suits to show where your length is, while partner has bid your void and suggested notrump in his two turns to bid.  You do have a bit in reserve, but there would be true extras if partner had not bid hearts.  What's your next move?  Run to your six-bagger to slow things down with your misfit, raise notrump with your void and concerns about transportation, bid the fourth suit because partner has implied the suit, or something else altogether.

2    90   BWP 36%   BWS 25%  IAC No solvers
The strongest action taken was to bid the fourth suit; but it doesn't sound like such a strong action by listening to the Panelists.  Danny Kleinman is "Torn between two clubs and three clubs.  If I can get by - er, I mean - if I can torture a three-club preference from partner, I'll bid five."  Howard Weinstein says "While partner may visualize 4=1=3=5, this avoids the underbid of two clubs and distortion of three clubs."  John Carruthers: "At the risk of ambiguity with 4=0=4=5.  If raised, I'll try to limp back to clubs."  Karen McCallum believes "If partner knows about the heart shortness, he's likely to make the right decision."  While David Berkowitz simply "Shows 12 cards of my shape with extras."

3 ♣   80   BWP 25%   BWS 19%  IAC No solvers
The jump in clubs shows the extra length and values.  Finn Kolesnik thinks "Partner had a reason to bid notrump.  If clubs come in, we should have good prospects in three notrump, and three clubs should be safe enough opposite two-low or a stiff honor."  Sami Kehela qualifies Finn's assessment:  "A very powerful hand if North has a decent club fit.  This is the way to announce that."  But my question is, will partner be expecting a better club suit, or understand that he needs to bring club honors to the party?  Billy Eisenberg "Imperfect, but this is too strong for two clubs."  Nik Demirev feels "If partner bids, he can show location of strength, and I can make a strain decision."  I thought by jumping in clubs, you were throwing the strain decision to partner.  Nonetheless, I agree with Robert Wolff that "Raising notrump is not close."  And Brian Glubok may have the best point:  "Whatever happens, I'll be in a reasonably-strong position to blame partner."

2 ♣   100   BWP 39%   BWS 47%  IAC  91%
The anemic club suit has a plurality of the Panel and BWS solvers pulling in their horns; as for the IAC, nearly everyone was on board with taking the low road.  JCreech lays out the situation well: "The void in partner's suit and the jack-sixth length suggest to me be conservative.  This is another hand where if partner can take another move, I will likely bid a game."  Carl Hudecek "Let's play in a strain where we can make something."  Steve Robinson says "We need partner to hold a club fit to be able to make game.  A three-club jump requires stronger clubs."  Masse24: "Do not like my heart void. Not worth 2NT. Almost worth 3 !C, but my suit quality and void in partner's suit convince me to go low."  Eric Kokish thinks "Knowledge of a six-card suit will sometimes encourage North to raise.  After  shape-showing two diamonds, it might be tough to get back to clubs, as North will often love diamonds."  YleeXotee is "showing the crummy clubs again but at least there are 6 of them"  Fred Stewart is "Going low with a crummy suit.  A game-try would be begging to reach a poor-play three notrump opposite some pretty-good North hands."  Larry Robbins: "This will usually be better spot than one notrump.  If the opponents can run five hearts, declarer will be hard pressed for pitches off this dummy."  Eric Stoltz "The clubs are too weak to do more at this point."  CCR3: "Showing length in view of the heart void."  Daniel Korbel: "If partner has a little bit, I hope to learn about it."  WackoJack: "Considered 2N and rejected it."  Hoki "can’t stomach being stuck in NT"  But BluBayou thinks "Leaving in  1NT  can't be hideous,  but 2 !C , 2, !D [size=78%] or 2[/size] !S  should be fine too.  The trouble is  when I hear 2 diamonds, after my retreat to 2 clubs, I am gonna raise it.  That could get embarrassing.  But I have learned that the 6-9 point-range for pard's 1NT rebid turns out to be 10 points really often."

What call do you make?

It doesn't take much for this hand to make slam, but then partner could have a very nice hand that simply doesn't fit and you get overboard.  How best to describe this distributional monster?  Make a demand bid to clarify your strength early, or take your chances by opening at the one-level to give you more opportunities to clarify your shape.

2 ♣   70   BWS 18%   BWS 17%  IAC 1 solver
For those who fear their opening bid passed out, we have 2 !CZach Grossack: "I can't stand the thought of one spade passed out when we can make six clubs.  I plan to bid spades, spades, clubs, then six clubs (unless at some point partner supports a black suit, in which case I will use an exclusion-key-card-ask)."  Rozanne and Bill Pollack: "To open a two-suiter with two clubs, the hand must be very big."  Fred Stewart: "Yes, there will be a lot of bidding, but I'm unafraid of any level to which I might be pushed."  Nik Demirev: "Normally, I'd prefer opening one spade with this shape, but here there are special conditions.  When North has two spades, four spades is likely best; clubs will generally be better when North has more clubs than spades, not playing in a black suit could be right only in rare cases, hard to diagnose below three notrump.  I hope to bid spades once, then clubs twice."  I found Daniel Korbel's reason interesting: "Zia has been imploring me to open two clubs more often.  If I opened one spade and he saw the answer, I would be in big trouble."  And where is Zia?  Not among the 2 !C bidders, though he does express a strong opinion about how the hand should be opened.  Yet I found DickHy to have the most persuasive reason: "Yeah, the purist voice in my ear is purring 'one spade, honey.'   Who’s got time for pure bridge??"

1 ♣   90   BWS 36%   BWS 9%  IAC 36%
So if you open one of a suit, which one do you choose?  Clubs are solid; if partner is void, you can still pick up the suit if they break 4=3, and that is the worst case scenario.  Even if the clubs were not so solid, the correct order for bidding touching suits is the top suit; with spades and clubs, the top suit is clubs.  Let's hear from the man who famously says, if you don't open a major suit, you cannot hold at least five in the suit:  Steve Robinson "I want to set clubs as trump, since the suit plays opposite a void; it will be difficult to do this if I don't open one club."  Similarly, Robert Wolff "I would not have thought that I would open a lower-ranking suit with equal length in spades, but I was wrong.  For slam, clubs will likely be better than spades."  Masse24 considers the bid "Risky. Banking on red suit calls at a high level allowing me to stick in a spade bid to give partner a choice. 'Normal' is of course opening 1 !S."  Interestingly enough, Jeff Rubens makes the bid citing "Safety first; publicity last."  Larry Robbins points out that "I can easily bid spades over red suits.  I don't want to open one spade and then need to guess which suit to bid over four hearts."  Carl Hudecek "Leaves maximum room for numerous spade bids.  I hope to jump to two spades, then to bid three spades, then to bid four spades."  David Berkowitz says "If I open one spade, no matter how many times I bid clubs thereafter, partner won't think in terms of six solid clubs."  YleeXotee "flipped a coin on this. the OLD school is a 1c bid, but the new school is 1s bid, but maybe this is the kind of hand that made old school right."  JCreech: "I would be inclined at the table to bid clubs first, but even with Panel, the clubs feel like a card or two longer than the spades."  Danny Kleinman brings up his esoteric rules: "Be wary of omnibus two-club openings on freak hands, and be wary of bidding spades before clubs with black two-suiters."  And Zia draws upon his rubber-bridge experience: "This will separate the bridge players from the pigeons.  This hand has a seven-card suit."

1 ♠   100   BWS 46%   BWS 74%  IAC 55%
Despite all the arguments for opening 1 !C, a majority of the solvers and a plurality of the Panel opt to open 1 !S.  Let's start with a Brian Glubok channeling: "I can hear Al Roth asking, 'Where do you get these problems?'"  I like Howard Weinstein's thoughts. "Usually, I would open two clubs if we might be cold for slam if partner passed a one-bid, but I also have a guideline that if slam may be poor or worse if partner has an opening hand, avoid opening two clubs.  Here, North could have a hand similar to South's and probably there would be no slam." but they seem as applicable to opening 1 !C as it does 1 !S.  The big argument for opening 1 !S is that partner will be thinking that the clubs are longer.  John Diamond "If I start with one club, partner will wind up thinking my hand is five=six."  Eric Kokish "Those who like one club to keep bidding spades at more-convenient levels later have a good case, but after a third spade bid they will have portrayed six+seven, not such a small thing."  Karen McCallum thinks there is "Plenty of time to get this right.  I'm hoping for an exclusion-key-card=ask sequence, and starting low will increase the chance of that (unless the opponents will keep quiet and partner will raise spades."  However, many of the IAC solvers are more focused on explaining why they are opening at the one-level, and not 2 !CCCR3: "Avoiding 2 C with 2 suits. Looks like a great hand but only 16 points.  Lots of points around the table. I'll get another chance to bid."  WackoJack: "It will not be passed out"  Hoki: "'normal' (dare I say that?)"  John Carruthers discusses some of the unique issues this hand presents: "It is rare to open a two-loser hand at the one-level.  The sixth spade steers me away from one club.  There is no chance of all pass.  The biggest downside is the possible difficulty in describing the hand later, but that would not be alleviated by a two-club opening."  While BluBayou likes to tie current hands to similar ones from the recent past:  "Last month's companion board ( Problem E)  was  AKQxxx, ---, K, AKJTxx.   There probably won't be serious objection from the panel  with the assigned 2 !C   opening with this 21-count,  but there will be with the o-so-similar 16-count here."



This ends Part 2.  I will be back with Part 3 when I have time.  Meanwhile, do not forget to submit your answers to next month's MSC.  I know I am missing one answer, but I will finish up after Part 3 is complete.

What call do you make?

You have opened, LHO overcalled and partner made an invitational NT call.  Your values are on the low end of an opening bid, but you do have a singleton queen in the opponent's suit to help bolster partner's stopper, and you have a nice six-bagger, but unless partner has help for your suit, it is unlikely to run without giving up the lead.  Do you accept the invitation, and if not, you have some non-forcing options. The last consideration is that this is matchpoints, where a plus can be worth more than being in a risky game.

Certainly the quickest way to turn down an invitation is to pass.  If the NT partial makes, it will score better than diamonds, but it clearly gives up on the game bonus.  Eric Stoltz votes strain over level: "Playing in exactly two notrump is rarely right at imps, but at matchpoints being in the most-productive strain often pays big dividends.  There is no need to press for a close game if you are in the winning strain."  Jeff Rubens agrees: "If we can make three notrump, it might not be necessary to bid it to obtain a good score; and we might be able to make only eight tricks at notrump."  Finn Kolesnik indicates that "Passing is a sensible option ... given matchpoint scoring and the possibility of being set many tricks in three notrump.  At matchpoints, I wouldn't consider playing in diamonds with a source of tricks such as the one I have."

Bidding one of the two hints drew a majority of the solvers.  Although it does not give up on the game bonus, there is a question on whether partner will take the bid as constructive, looking for some diamond help to try being in game.  Larry Robbins argues: "Even with a double spade-stopper, we may fare best in three diamonds.  Partner will usually pass, but with a perfect minimum, say:  ♠ AJxx    xxx    Qx   ♣ Axxx, North  may trot out three notrump.  Yes, it is matchpoints, but three diamonds is more likely to produce a plus score."  SImilarly, JCreech thinks "The !S Q makes it tempting to bid 3 NT, but I am worried about where the tricks may come from.  With fitting diamonds, partner can retry for 3 NT by bidding hearts, spades or NT."  DickHy: "Partner has 11/12 (1N would have been 6-10) and something like Axxx KJx xx QJxx.  Where do we want to be?  If partner has the spade T or 9, 3N might be decent, as he can win the opening spade trick x-Q-K-A knowing that West can’t run the suit.  Without a good spade spot, West, after winning the opening spade lead with the K can carry on with the suit (if he has an outside entry) or can switch … to a heart across partner’s holding.  That looks gloomy.  At least if it comes down to a heart guess, partner is more likely to get it right than I am.  At matchpoints is choosing a fairly certain part-score better than opting for a fraught game?  I hope you wizards will tell me.  Meanwhile, I can chew over whether it’s better to pass 2N or play 3 !D in a 6-2 fit. "  Some have serious concerns about playing in NT.  Karen McCallum feels that "Usually three notrump will have no hope, and matchpoints is about frequency.  Passing is out of the question.  Reaching two notrump with a six-card minor is dancing on the head of a pin."  CCR3 wants "to ward off NT noting the singleton spade and three small hearts."  Daniel Korbel writes: "At imps, a blind raise to three notrump; but notrump could be in danger in hearts or spades, so it is not a good matchpoint risk."  Danny Kleinman is "Taking our (likely) plus score.  The values are meager, and we're not sure how good our spade queen will prove to be.  There's also the considerable possibility of a heart attack once lefty gets in."  Carl Hudecek: "I don't consider that an opening bid, since the suit is a minor.  Partner has spade values.  We are short of HCP for three notrump, possibly with as few as 23.  Partner can move on with an in-context perfecto such as:  ♠ KJx    K10x xxxx   ♣ Axx."  YleeXotee "considered pass in hopes that diamonds will run, but why not just make them trump in a partial"  WackoJack "Reckon just good enough to bid 3N at imps.  However, at MP just 3D"  Masse24 "My Hamman-o-meter dinged once, then stopped. Although the panel is aggressive, I don't feel it's quite worth the 3NT gamble."  Hoki choice is based on being "... consistent with my philosophy that bridge is bridge and poker is poker"  Blubayou guesses the Panel will choose differently than his choice:  "So, the two horse race was a battle between correcting to diamonds and RAISING notrump!  So far this is a tight battle.  The panel  will go for the game bonus, counting on 3NT being cold  or sneaking home by a less than double-dummy  opening lead"

Jock correcly predicted that the majority of Panelists would turn to Hamman's rule, and bid the NT game; they were reluctant to name names.  Brian Glubok said "No need to invoke Hamman's Law; just bid three notrump and collect the game bonus."  Sami Kehela: "BWS: Trying for game by partnership agreement."  Fred Stewart: "I anticipate two spade tricks, and we don't need a heck of a lot for nine."  John Carruthers: "I have two more tricks than I might have had and a bolstering spade queen - plus my natural optimism."  Mark Cohen disagrees with Hudecek's valuation: "This holding is a lot better than 12 HCP with no special source of tricks."  As does David Berkowitz: "The spade queen is a full value in notrump."  Eric Kokish: "Even at matchpoints, and even though there are lots of ways for three notrump to fail when the spade queen is working.  Prime values and a trick source are too attractive to sign off."  Bart Bramley thinks "We could have nine runners after a spade lead."  Phillip Alder points out that there is "No way to invite game."  Zach Grossack is "Happy to bid game with a clear source of tricks and a potentially-quite-helpful queen of spades."  John Diamond feels "The good six-card suit is sufficient to try this."  Nik Demirev summarizes the choice well: "At matchpoints, partner would be careful not to overbid, so it is easy to visualize a lot of North hands with a double spade stopper or providing nine fast tricks after we get the lead."




Problem B  3 !C (CCR3, BluBayou, YleeXotee, Masse24)

Imps  Neither side vulnerable
You, South, hold:

♠ —    A J 5    10 9 7 6 4 2   ♣ A K 9 8

SOUTH   WEST   NORTH   EAST

*BWS: as if West had passed (2 ♠ would have
been a strong diamond raise)
†four spades

What call do you make?
 
East opened 1 !C in third seat and you overcalled with a 10-sixth suit, but 12 nice points in your shorter suits plus a void in spades.  West now bid 1 !S, while partner cue-bid clubs and East raised the spades.  The implication of the cue-bid is that it shows a fit for your diamonds, but for some reason, the hint only talks about what a spade bid would have shown, had West had not already bid the suit.  I prefer to think in terms of there being two suits that can be used as cue-bids; clubs being cheaper and spades as more expensive (those characterizations should apply to both North and South, but what are their implications?  Do they convey differing levels of strength, or do they show stoppers, and is any of this affected by North being a passed hand?

Since 2 !C promises support, and you hold six, perhaps it is worth a 1-2-3-stop-like auction.  Fred Stewart "Three clubs might lead to an ugly three notrump.  A pass would be nonforcing."  And you think 3 !D is forcing?  At least 3 !C would help partner understand that there is a double fit.

5    70   BWP 11%   BWS 8% IAC 27%
Working from similar logic, DickHy writes "According to BWS [C(b)] a passed hand cue-bid guarantees a fit.  I guess in this auction 2 !D could show a fit but a weak hand, 2 !C a decent raise (6-9) and 2 !S (10/11) a good one.  Partner looks to have 4 spades.  With nice spades and Qxx in diamonds, say, he might have bid 1N.  Ergo (these Italian drugs are graaaaaaaaaaaaaaaate), he has paltry spades and Axxx in diamonds. Carpe diem!"  John Diamond says, "Might as well bid it immediately."  JCreech: "Not sure what 2 !C means.  As a passed hand, I think it is showing a good passed hand with a fit.  I'm not sure who can make what, but I don't want to guess when the opponents bid 4 !S, but I think I will get a plus if they bid 5 !S."  Larry Robbins has other concerns: "I won't pass three notrump.  We could have a slam, but it will be difficult to bid, even if I cue-bid (which might help the opponents find a sacrifice)."

3 ♠   60   BWP 7%   BWS 10% IAC 27%
Some cue-bid.  Nik Demirev considers how the auction will proceed:  "Followed by a control-bid, depending on the auction.  Four-card support will make five diamonds a decent contract, and slam, even a grand slam, is possible.  Stopping short of five diamonds is not ideal at imps, even though that contrct may fail."  WackoJack feels "That tells partner game interest"  While John Carruthers says "I'm up for whatever North intends."

4 ♠   70   BWP 11%   BWS 4% IAC No solvers
Although a cue-bid uses a lot of space, a jump-cue eats twice as much, but is quite descriptive.  As Karen McCallum puts it: "For a slam-try opposite a passed hand, partner should expect a spade void and aces."  Eric Kokish: "Our maximum might be a high partial, but it's far more likely to be a slam."  Phillip Alder says "I will be happy to play in five diamonds, and we might will have a slam."

3 ♣   100   BWP 61%   BWS 44% IAC 36%
A majority of the Panel and a plurality of the solvers cose to use the cheaper available cue-bid:  3 !CBluBayou "The hint sent me running to the OKB system notes!   IT made me think that both cuebids show "strong diamond raises", which is odd.  But no.  Turns out that 2 !C  has two legs.  It can be the usual invite+ in diamonds, but also a really strong hand  (in context)  coming in a different suit.   With that possibility in mind,  I see no haarm in bidding my club suit, in case partner has a 1H opener which will be lovely,  or even a club-heart two-suiter--even lovelier.  I really expect we are headed for 4 or 5 hearts or 5 clubs."  Jock, where are we headed here?  Masse24 says "Game try. Who knows which game."  Some think the bid shows clubs.  Mark Cohen: "Most flexible opposite a passed hand; encouraging with club values.  I will not pass three notrump."  Danny Kleinman: "Bidding 'em where they is.  If the opponents buy the contrct in spades, I can hope that partner will lead clubs."  Daniel Korbel: "If partner can hold four diamonds, we could have a slam.  May as well show my second suit on the way to five diamonds." Well, I guess it could; often when you have a choice of two cue-bids, the one bid is often a "tell" rather than an "ask."  Robert Wolff describes the bid as a "General forward-going action.  The hand may be worth only three diamonds, but I plan to drive higher."  Jeff Rubens:  "The diamonds are too weak to drive to five diamonds, so I will consult partner."  Finn Kolesnik: "Three notrump or five diamonds might have good play; this keeps both in the picture.  I will pass if North bids three diamonds or compete to four diamonds if the opponents bid three spades."  Steve Robinson: "With plenty of defense against spades, there is no need to jump to five diamonds.  Partner will know that I am short in spades; he will be aggressive with strong diamonds."  Zach Grossack: "I will force to some game but will need convincing that it should not to be in diamonds.  The poor quality of the suit makes the hand oriented for a suit contract, and a slam is possible.  For now, I show a concentration in clubs."  Rozanne and Bill Pollack: "If partner has four diamonds (very likely but not certain), we have quite the duke.  Will try to be somewhat descriptive, but it will not be surprising if it's four spades or eight spades by the time the auction comes back."  Nonetheless, David Berkowitz warns that the auction may not be over for the opponents:  "Must anticipate more spade bidding.  Not interested in notrump, but this is a mighty nice hand if partner has strong diamonds."





Problem C  1 NT (DickHy, Hoki, CCR3, Masse24, JCreech, BabsG, WackoJack, YleeXotee, VeeRee, VeredK)

What call do you make?

This hand is very much like Problem D from last month; the differences being when the overcall occurs in the auction and which seat is balancing. This time, you opened 1 !D which was passed to East, who balanced 1 !H.   The concern about right-siding the contract with respect to hearts is essentially gone; your AQ is sitting over the heart bidder.  Nonetheless, partner still has few points, as he did not respond to your opening bid.  And the Panel splits on this hand considerably differently; last month, nearly the whole Panel went with the 1NT rebid, none doubled, and we solvers were stunned to see 1 !S as the primary alternative to 1NT; this time, those same three options are more evenly split.

1 NT   100   BWP 39%   BWS 60% IAC 91%
A majority of the solvers return to the tried-and-true, as well as a plurality of the Panel.  DickHy said:  "At the table I’d bang this out with nary a second thought. "  Masse24: "A bit of a tease? So similar to last week's "WTP unanimous?" problem. But it's different."  JCreech: "The right values and right-siding the hand still outweigh bidding or asking partner to bid the spades"  CCR3: "perfectly describes values and can tolerate the heart lead."  YleeXotee: "seems normal"  Wackojack: "That is what I have"  Larry Robbins: "Where we want to land opposite a flat hand, such as 3=4=3=3, where North might bid two diamonds if I doubled.  One spade should be more distributional.  One notrump loses the club suit but is the contract most likely to make."  Eric Kokish: "An opportunity to offer a clear description should not be discarded in favor of a safer double at this vulnerability.  We could buy 2 or 3 HCP and be in the best contract."  Daniel Korbel: "Sure, double could work out better, but when I am supposed to bid one notrump, it's very important to do so (e.g., opposite a balanced hand with scattered bits, where I'd rather not watch partner struggle in two clubs)."  Finn Kolesnik: "Double is possible, but the holding doesn't look suit-oriented.  One notrump might suffer extra undertricks, but nonvulnerable at imps this is not scary."  Phillip Alder: "Double will do well when North has four spades, but I will not feel happy if partner bids two clubs, even though that might be the best spot."  Zia: "Mild danger.  Greater temptation."

1 ♠   80   BWP 25%   BWS 9% IAC  No solvers
1 !S was a solver surprise last month; this month, not such a surprise and more popular with both the Panel and solvers than last month.  What's the attraction?  Bart Bramley thinks "A suit should be safer than notrump, and spades is my best suit.  With 2=4=2=5, partner might try clubs on the way to two diamonds.  If I doubled, partner might pick diamonds with three than spades with a weak four."  John Carruthers is "Hoping for a trick or two more than in notrump."  Nik  Demirev: "Introducing spades may help us compete if the opponents bid more hearts."  Carl Hudecek: "Partner can't hold that much, so I compete quietly."  Jeff Rubens: "Any positive action risks reaching the wrong strain, but this stays low and is a likely plus."  which leads us to Danny Kleinman's rule: "What I should have bid last turn.  I've seen too many balanced nineteeners get passed in one of a minor when opening in a strong four-card major would have found a fit (perhaps even a raise and a game).  Rule of 19:  With a balanced 19-or-so high-card points, open in a strong four-card major if you have one."

Last month, it was like the Panel did not know that a takeout double existed; this month, it is very nearly the top choice.  Brian Glubok is very confident that double will be the Panel's choice:  "No comment will be helpful, because double will inevitably prove the unanimous choice."  Fred Stewart thinks "A notrump bid would be fraught with risk, as there is no source of tricks."  Zach Grossack: "No reason to bid one notrump when our goal is to compete effectively."  John Diamond believes double is "Best for reaching the right strain."  Concern about the spade suit is still paramount for some of the Panel.  Karen McCallum sees "No point in bidding one spade; partner won't be on lead.  If North has long clubs, I want him to feel free to bid the suit.  One notrump is more descriptive, but partner won't care, so why wrn the opponents to stay low or help them with the play?"  Eric Stoltz: "One notrump would not bring spades into the picture; bidding one spade would misdescribe diamonds; double better shows all-around values."  Rozanne and Bill Pollack is in "No rush for notrump, and we can't afford to lose a spade fit.  We reject one spade with a flat hand and lots of extras.  We need a sign of life opposite to make a game."  Steve Robinson "I want to bring spades into the picture.  If I were to bid one notrump, partner would pass with four spades.  Opposite a weak hand, we'll do better in a trump suit, even if only a seven-card fit.  I'd bid one spade if I had only two clubs."  BluBayou has his own special take on this: "They're having a little joke here-- this is last month's  problem D with the heart noise coming from righty instead of lefty!  March problem D had a stunning 25 votes to  become declarer.  Will a majority be sucked in by the heart  AQ even though  "right-siding" is not an issue anymore? It depends on whether or not after doubling, we are willing to lie down for partner's runout to 2 of either minor.   It is IMPS,  so I am OK with being dummy  to 2 clubs or playing 2  diamonds"



This ends Part 1 of the summary.  I hope you found something interesting or useful in it.  Todd has opened up the discussion for next month's problems.  Please start thinking about your answers and contribute.

Here are my initial thoughts:

Problem A:  3 !H  I don't know where Jock gets off thinking there are only two options, I can see two cue-bids available for the aggressive, in addition to the two he identified.  Would I choose one of the cue-bids?  Probably not.  Are they unreasonable?  No.  You only need nine HCPs from partner to have a reasonable shot at the heart game (less with the unlikely singleton or void in diamonds).  Nonetheless, I find solice in the LAW.  Pass is too weak and the cue-bid too strong, while 3 !H is just right.

Problem B:  3 !H  The LAW guides me again.  Let's get to our proper level as quickly as possible.  This may result in the opponents continuing to imprudently bidding spades, but it will also make it more difficult for the opponents to find an alternative strain.

Problem C:  4 !S  I typically like to blast to the level I want to be at immediately.  I may come to regret not bidding to the implied level of the LAW, but the 5-level is frequently daunting.  I will gamble that game will suffice.

Problem D:  Pass.  Partner's bidding typically shows a weak hand with long hearts and no fit for my diamonds.  Time to quit trying for better.

Problem E:  2 !H  The semi-forcing 1 NT is my bugaboo with this hand.  Although I am not distraught to play in NT with this hand, I'd much rather be in the 8-card heart fit and leave partner's hand hidden.  I raise; support with support.

Problem F:  1 NT  I am torn between 1 NT, raise partner and pass.  I am minimum opposite a passed hand, but I also have a maximum, full-values for my minimum.  I do not want to encourage the opponents to enter the fray with the pass, and I don't want to encourage partner too much with a raise (particularly if he only has four), so I split the difference with the very descriptive 1 NT.

Problem G:  c4 (open 1 !C, then reverse into 2 !D)  I see no reason to distort my shape.  I wish I had some better spot-cards, but this hand has primes, so I am willing to reverse on this 16.

Problem H:  ?  Pulling a Jock here - Still trying to work this one out.  A spade may pickle partner's holding and thereby the entire suit.  A heart doesn't feel like it will help, being the suit of a hand that doubled and bid, though declarer doesn't seem to have a fit.  Diamonds are my best holding, but they may not be well placed for a lead with the NT bidder on my right; I probably should wait on the suit.  And declarer should definitely have some clubs, and despite my opening bid, I do not.  I'm beginning to think that Hideous Hog's lead advice to Rueful Rabbit may be best - 7th from either the right or left.  I hate to say this, but my strongest inclination right now is to lead the !D Q, like last month, hoping to hit Jxxxx with partner.
