to  Jcreech  re:  problem B...BWS promises 4 clubs+  for the  1C, 1D; 1major auction.   Please look it up,  and ruin my day  or several of them  if I am wrong   :P

Hi Jock,

You may be right because the subsection I read is confusing.  Now I may be misreading this, so I am putting the quote for all to see and help me misinterpret:

Under H. After Our Minor-Suit Opening in the subsection on Opener's Rebids:
Quote
(b) with 4-4-3-2 too weak to open one notrump and lacking four-card support, rebid in a four-card suit at the one-level when possible, except with 4=4=2=3 (bid one notrump);

There are two parts to this, and I just noticed that the first part separates the shape elements with "-" and the second part with "=".  I now suspect the "-" can place the shape elements with any of the suits, while the "=" keeps the shape element with the location in the series (i.e., the first element is spades, the second hearts, and so forth.  So 4=4=2=3 would be a possible form of 4-4-3-2.

That being said, the second part would apply for auctions that begin 1 !C-1 !D, and if partner held 4=4=2=3, would rebid 1NT, so a rebid of 1 !H shows at least four clubs, as Jock said. 

However, the first part, read quickly, suggests that with 4=4=2=3, that opener would rebid 1 !H without a raise of diamonds, but is really aimed at auctions that begin 1 minor - 1 !H, so that when opener holds four spades and fewer than 4 hearts, the rebid is 1 !S.  I think this could have been written more clearly.

Nonetheless, the diamond suit, Burns' first law notwithstanding, has a strong potential as a source of tricks, and as many panelists has said over the years, "it is where I live."  I am going to stick with 2 !D as my initial choice, though Jock's arguments have increased my likelihood of switching before submission.

My initial thoughts:

Problem A:  3 !C  Seems like the best description; it shows nearly half my hand in terms of suit, and my values. My other choice was the inverted raise promising at least one more diamond or something worse.  I could trot out 1 NT, but with nothing higher than a nine, that begs disaster from my side.

Problem B:  2 !D  Best description again.  That diamond suit looks like six, and partner has only promised four hearts and three clubs if 4-4-2-3; the percentages suggest that partner has more clubs, but I would rather play in diamonds opposite a stiff or void than clubs opposite xxx.

Problem C:  3 !S  This is close; if we were red, I would regard the try as automatic, but white at imps, pushing for game is not as important.  With opener sitting behind me, I think it is worth the try for game. 

Problem D:  3 NT  The values are about right, the stop (with potential for a second stop) is right, the question is whether we have the tricks.

Problem E:  2 !D  This is why I like playing weak NT; I bid my NT and follow partner's lead.  On this auction, I have a decent suit to rebid, but tend to promise more length.  Partner's negative double just forced me to rebid a five-bagger when a Moysian is not particularly good (especially in hearts where I would be ruffing with an honor).

Problem F:  Pass  This definitely feels like an underbid, but where am I headed.  I need help for a notrump stopper.  In spades, the wrong hand is tapped.  If partner has three or four diamonds, that would be good, but difficult to get to except with a negative double and you are more likely to hear spades than diamonds.  And clubs, you need partner to have at least five. If partner has a good hand, we will have another chance to bid; he is clearly short in hearts.

Problem G:  2 NT  What I really want is 3 !D forcing for one-round, then if partner rebids hearts, I can bid notrump.  2NT and 3NT are both possibilities, but I really do not want to hear partner bidding 4 !H next.

Problem H:  !D J  Trying dummy's second suit.  It sounds like declarer has the club control, so maybe the king is well placed, and my trump length may give some problems, but I don't want to advertise.  A heart looks wrong with LHO bidding the suit and I don't know if the top honors are together or split yet.  That leaves diamonds, the sequence is also suggestive.

Sorry, between computer problems and burn out, I am struggling to participate in MSC  Below are my initial thoughts and final answers:

SOLUTIONS FOR:
James Creech
Fredericksburg VA 22407
U.S.A.

PROBLEM A: 3 Notrump  Taking the hint.  If my values were spread out more, I might want to choose between an invitation or a splinter.  With the concentration in spades, but with a side ace, I think preemptive feels right, plus the bonus of some defense.
PROBLEM B: 3 Clubs  We are already in a game force, so I think we keep it low and point to my extra length and concentration of values.
PROBLEM C: Pass  Torn between RKC, a control bid and a forcing pass.  The forcing pass seems more flexible, and I am worried about no 1st or 2nd round control in the unbid clubs.
PROBLEM D: 2 Notrump  I was torn between two game tries; 2NT showing the outside stops and an alternative place to play, or 3C, looking for some help.  2NT seemed more flexible because partner could pass or bid 3 !H depending on the character of his hand.
PROBLEM E: 3 Clubs  Using the hint.  I'm taking a move forward, and while 3 !C does not show a spade fit, it also does not deny one.  Therefore, I can show the spade fit next, while showing partner where I have my values.
PROBLEM F: Double  This time I am counting on equal-level conversion, so if partner bids diamonds, I can bid hearts to show two places to play without showing extra strength.
PROBLEM G: 3 Diamonds  Partner jumped, so I feel I am too good to pass, but don't like my other alternatives.  Why didn't I just overcall 1NT and get my hand off my chest in round one?
PROBLEM H: Heart 5  It sounds like a 5-3 fit with dummy coming down with a singleton.  I don't have great trump, but I really don't expect to pickle partner's holding.  Let us get some children off the street.

Problem A:  3NT  I have had some of Hoki's concerns about 3NT and had just about pulled the trigger on 4 !H, when I took a moment to construct a minimum where partner might have bid as they have in the problem:  ♠ x   ♥ QJxxx   ♦ KTx   ♣ AKQx.  I think partner could have a bit more, but I think KT8x should be sufficient to tie up the spades long enough to scramble nine tricks.
 
Problem B  2 !D It is tempting to splinter on this, but the purpose of a splinter is to show fit (check) and highlight the side suits (no check).  There is one side-suit that is also of splinter length.  So I will show partner where I live before I show the fit.

Problem C 4 !C  Really torn on this one, more because of the options not available.  If partner had started with one heart, I would have had the impossible spade to show the big club fit.  Now I only seem to have various levels of club raises, and how high is largely a guess.  I have wonderful controls, but limited values, and a lot of clubs.  I have no presumption that 4 !C is forcing, but it should be invitational

Problem D  Double I have roughly invitational values and not so distributional that I could not bear to hear partner pass.  But the real point is that partner could have four spades, two hearts or a willingness to play in 3NT if balanced.  At matchpoints I feel we need to compete here.

Problem E  3 !C  I with Hoki, in that I am not certain that I want push the opponent's into game.  The advantage of 3 !C is that it helps partner with the lead if they play in the presumed heart contract and it hasn't necessarily given up on spades.  I guess what I am saying is that it is a more flexible bid, with distinct immediate advantages.

Problem F 3 !D  Torn between going low with 3 !D amd high with a Western cue.  At IMPs not-vulnerable, I will aim low and hope the Panel is not hungry for a game.

Problem G  Double  I can always leap about in diamonds later, but we may have a heart fit.  And knowledge of the double fit may be critical before the end.

Problem H !S A  This is such a terrible lot to lead from, I can only think about the invitation via clubs (btw my best suit), so the key may be to find out and knockout the side entry.  So I am leading the spade ace to look at dummy and figure out what to attack next.

BWS section E  "Competition After Our Minor Suit Opening":
After our minor-suit opening and an overcall:(a) a double is negative through three spades.
So, how does that allow a double of 3S to win the quizz, with  xxxx, Kx, KJx, AKxx, huhh??   And why did 11 panelists  choose this?  Granted, the other 3 or 4 possible answers are  yukk

I agree with you, Jock.  The winning bid on Problem E was off the wall.  I would have felt much better with the shape bending 4 !C, that appeared as second.

However, I am having a hard time squaring the weird winning response on Problem E with the repudiation of Hamman on Problem B.  Although I agree with 4 !D, and reluctantly tried to hit the field, I was shocked to see only one Panelist going with 3 NT.

Here are my submitted answers.  One change from the inital guesses; appropriately telegraphed.


SOLUTIONS FOR:
James Creech
Fredericksburg VA 22407
U.S.A.

PROBLEM A: 4 Notrump
PROBLEM B: 3 Notrump  As soon as I mentioned Hamman in my initial guesses I knew in my heart that I would bid 3 NT, despite the high probability the the opps would attack my weakness.
PROBLEM C: 3 Notrump
PROBLEM D: Pass
PROBLEM E: 4 Spades
PROBLEM F: (f)
PROBLEM G: 5 Diamonds
PROBLEM H: Spade 9

My big question on Problem G is where is the spade raise from East?  If partner is short in spades and I only have the stiff king, why wasn't there a courtesy bump?  I feel certain that partner has too many points to pass, and not good enough spades to bid 3NT, so Todd's "almost guantee" that partner holds four hearts is not my gut feeling on the hand.  My gut is saying AKx or AQJ with a bad split looming and the spade ruffs coming in the long hand.

July MSC SUMMARY (Part 3) – David Berkowitz, Director

Problem F  3 NT  (BabsG, JCreech, Masse24, WackoJack, YleeXotee, BluBayou, Hoki, CCR3, VeredK)

Matchpoints  North-South vulnerable
You, South, hold:

♠ J    A 10 9 4    Q J 5   ♣ J 9 6 5 4

SOUTH   WEST   NORTH   EAST
  ——      ——       2 ♣        2
  Pass*      3       3 ♠       Pass
   ?         
*BWS: denies double-negative strength

What call do you make?

Partner has announced a moose, and the opponents throwing up a minor barrage in diamonds.  Of course, partner's suit is your singleton jack in spades, you have a stop in diamonds and length in the round suits (including the heart ace).  How should you approach this promising collection?

3 NT   100   BWP 56%   BWS 78%  IAC 100%
In a problem with the majority is across the board, Iain Sime is right on the money: "Hamman's Law.  If three notrump is where the matchpoints are, we need to bid it now."  Where is Todd?  Masse24 "I've shown values with my initial pass. This is sort of an interesting call since it conveys the nature of my hand. Partner is clearly short in diamonds, so will likely make another call. But if he passes, that's okay."  He is making the bid without giving the credit.  Robert Wolff: "Most descriptive bid available, although the hand is somewhat heavy."  Bart Bramley: "Obvious?"  DickHy thinks "For the 2 !C, partner could be balanced 22-24 (with Kx or xx) in diamonds.  That’s unlikely as E would then be ATxxx and W xxx, which seem rather meagre holdings for their bidding even if they are white v red.  Partner’s probably unbalanced and a tad stronger.  However, this is an opportunity to show my stops in the other suits.  Partner can still carry on."  JCreech is "Showing stoppers and some decent general values, but not much of a spade fit.  I wish I had a second spade, but perhaps I can borrow one from one of the round suits."  Danny Kleinman: "Anther fast ball down the middle."  Hoki worries a bit: "If my earlier pass shows at least something, then this does not have to end the auction."  But Zia is with him:  "I hope this won't end the auction."  Gary Cohler also has concerns:  "A little heavy, but there are some wasted values.  This keeps the auction low and might allow partner to show a side four-card suit.  If he bids four spades, I will control-bid hearts."  Wackojack "First thoughts were that I am too strong to bid 3NT. Say partner has ♠ AKQ10xx, Kxx, x, ♣ AKQ.  Then would we miss the ♣ or ♠ slam?  OTOH this is match point pairs and perhaps we should go for the certain 3NT +1 or +2."  Alan Sontag: "Partner has a chance to bid another suit or perhaps to cue-bid."  Now we start to feel the certainty that the auction is not over.  Eric Rodwell thinks "It is possible at these colors that partner has two low diamonds.  WHat other bid is more descriptive?  The hand lacks the values and the diamond holding for four notrump..  If North pulls, I'll be better placed."  John Carruthers argues that "We might make slam in spades (or clubs); if so, I hope partner will bid on.  We'll be away to the races if he bids four clubs."  And Sami Kehela believes "It's odds-on that North will remove, and we will then proceed to more-profitable ventures."

Where else might we go, if not notrump?

4 ♣   60   BWP 15%   BWS 10% IAC No solvers
One option is to bid your length.  Phillip Alder's assessment: "No doubt three notrump will enjoy popularity with the panel, but could lose in either of two ways; We go down there or we miss a slam."  Kit Woolsey thinks there is "No reason not to bid the five-card suit.  We could belong in clubs or have a slam in any of three strains.  Kerri and Steve Sanborn points to the more general strength: "Even with three low diamonds, this hand would be strong than a double negative."  And Larry Cohen finds the hand "Too strong for three notrump (I love the spade jack).  Wrong hand for four diamonds (whether or not that shows a diamond control)."

4    80   BWP 11%   BWS 1% IAC No solvers
Another is to bid your four-card major.  Ron Gerard: "Forcing. ... If partner retreats to four spades, I'll raise.  If North has clubs, I expect him to bid that suit next."  Bruce Rogoff feels the bid is "Forward-going for spades, not a suit that I could have introduced at the two-level."  More convincing to me, Jason Feldman says "With an ace and the jack of trumps, I owe partner more than a game bid."

4 NT   50   BWP 7%   BWS 0% IAC No solvers
You could stick to the popular strain, but suggest a bit in reserve.  Barry Bragin reasoning makes sense: "Natural; with spade support, I would cue-bid."  As does Eric Kokish: "If North is short in diamonds, we can finish in spades or clubs, but there is no bid over three spades that gets the strength across.  Saying that the diamond queen-jack are worthless would be presumptuous."

4 ♠   70   BWP 11%   BWS 7% IAC No solvers
Or you could raise with your Jackleton (to borrow from an earlier Panelist).  Billy Eisenberg thinks it "More comfortable than three notrump with only a single stopper."  Jeff Rubens points out that "The diamond quacks don't rate to be worth much on offense; if those are discounted, this is at worst a mild underbid, and even nonvulnerable interference suggests bad breaks."  Steve Gardner: "If three notrump is in the ballpark where fans gather to witness another October demise, I'll play it safe and avoid getting called out at the plate."

I'm with Adam Grossack who did bid 3NT:  "One working card and slow diamonds."  If all partner needs is one card from us, we will hear from him again, but let's show the slow stopper and give partner the maximum room to describe his hand if he wants to bid on.




Problem G  3 !D  (Hoki)

Matchpoints  East-West vulnerable
You, South, hold:

♠ 6    J 5 2    A K Q 4 3   ♣ A K Q 10

SOUTH   WEST   NORTH   EAST
  ——       2        Pass      Pass
   ?*         
*BWS: four of a minor = that minor plus spades (forcing); 4 = spades plus a minor

What call do you make?

This such a powerful hand, but the concentration of values in two suits makes it uncertain what direction to take.  Then add into the equation that the opponents preempted in your Jxx suit and you are sitting in the balancing seat.  As expected with an MSC problem, the solution is not obvious, nor satisfactory.
 
3    100   BWP 48%   BWS 29% IAC One solver
The top choice for the Panel seems like a give-up; a simple overcall in the balance seat just does not feel like it communicates the power of the hand.  Perhaps that is why Hoki, the only IAC solver to make the choice said: "Hmmm, no comment."  The comments from the Panel are not much more useful than to say there was a fear of a misfit, their best suits were minors, and going low was the best shot to make a plus.  To me, the best analysis for the winning choice was John Carruthers': "I'm usually more of an optimist, but for three notrump I need not only a half-stop in hearts but also big help in spades.  At least the game I may miss is nonvulnerable."  Bart Bramley: "Pass is too deep for me.  Anything at the four-level could be too high.  When in doubt, bid the long suit."  Carl Hudecek thinks "The hand has enough to pass two hearts at this scoring and vulnerability, but I'll go with the field."  Billy Eisenberg makes the bid "Despite the fact that it looks so cowardly."  Danny Kleinman doesn't see a problem: "A third fastball down the middle.  Has Hoyt Wilhelm retired from his job as Problem Setter."  Jeff Rubens: "Unlikely as it may seem, this may be too high."  Similarly, Jason Feldman: "We may not be able to make more on a misfit.  As East didn't raise, I don't like the chance of finding heart shortness with partner."  Barry Bragin: "My imaginary coin flipped to low."  Chip Martel is "Going low with no sensible bid to find a good game."  Robert Wolff: "Very heavy, but four notrump would be a huge gamble and risk playing in the wrong minor."  Iain Sime sums it up reasonably well: "Guessing and hoping that somebody bids."

3 NT   70   BWP 33%   BWS 8% IAC No solvers
Holding Jxx in the opponent's suit makes 3 NT an attractive likely game, but to bid it directly takes, to me, a leap of faith that partner has the right cards.  Bruce Rogoff describes what is needed: "All I need is some diamond length with a few major suit scraps (or even three low hearts and a high spade).  I can't think of any other sequence that will take us there intelligently."  Larry Cohen expresses my fear, but in a nice way:  "It would be fun to score minus 450 the hard way opposite, say, ♠ Q10    10xx    J10xx   ♣ Jxxx, after West leads a low heart to East's singleton king and East shifts to a low spade from ace-seventh."  Alan Sontag thinks it "Right form of scoring for a flight of fancy.  At least I will have a good story no matter which side makes three notrump."  Kit Woolsey says "Sometimes, one must gamble.  This looks to be one of those times.  Three notrump is very likely to be where we belong, and there is no sensible way to find out anything."  Gary Cohler: "Who knows?  Everything is flawed, so take a shot for the matchpoints.  Nobody has solid hearts any more."  Although Masse24 chose differently, he made these arguments for 3 NT: "I've shown values with my initial pass. This is sort of an interesting call since it conveys the nature of my hand. Partner is clearly short in diamonds, so will likely make another call. But if he passes, that's okay."  Zia: "Imperfect?  Pluperfect?  Never could get those right."  Eric Rodwell: "No heart raise makes me hopeful of buying an okay dummy.  Therre is substantially too much strength for three diamonds.  Double would be too likely to generate a later four-spade correction (and converting that to five diamonds might not work well)."  Kerri and Steve Sanborn: "The modern game."  The last word to Steve Gardner: "Time to put an end to my rather-dull habits."

3    40   BWP 7%   BWS 28%  IAC 44%
If 3 NT is a legitimate goal, then why is the cue-bid asking for heart help given such short shrift in the scoring?  True, you need help with more than just hearts, but hearts are the devil the whole table is aware of, while spades it the devil you are hoping to keep hidden.  Ron Gerard is "Asking for a stopper.  I'm tempted to pass and to play for hundreds, but I had this vision of partner's holding:  ♠ Axxxx    x    J10xx   ♣ xxx.  If North advances three spades, I will bid four diamonds."  Masse24: "Too strong to pass. Not right to double. That leaves this ambiguous cuebid. Hopefully, we can agree on a suit."  WackoJack: "I think shows the minors.  Problem:  What if partner then bids 3♠? I think I will bid 3NT and hold my breath."  JCreech: "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."

Double   50   BWP 11%   BWS 22%  IAC 22%
If spades is the flaw with a cue-bid asking for a heart stop, it is more of am issue for double.  At least when asking for a stopper, you can  be certain that if partner bid spades, they have a lot of spades.  If they bid spades after a double, they may be trying to keep the auction low with only three.  DickHy has a sensible plan for most situations.  "I’ll bid 3 !D over 2 !C or try not to go nuts over 3 !C.  I’ll break a 2N Lebensohl transfer with 3 !D.  If partner was intending to continue 3 !H (showing 4c spades and a heart stop), he can bid 3N."  While Sami Kehela is hoping that "Having passed over two hearts, partner is unlikely to offer a punishing four spades, perhaps leaving us room to alight in an acceptable trump suit."  And Adam Grossack thinks "Partner is unlikely to escalate to four spades, so I can correct to notrump."







Problem H  !C 6  (YleeXotee, WackoJack, VeredK, JCreech, Masse24, Hoki)

Imps  Both sides vulnerable
You, South, hold:

♠ 9 7    5 3    K Q J 8 6 5 2   ♣ 6 5

  Pass      Pass      Pass
What is your opening lead?

LHO opened your seven-bagger, partner overcalled in clubs, and RHO made a negative double.  LHO now bid notrump while RHO insisted on a major.  With no four-card major, I think dummy will come down with something like 0=3=5=5 or 1=3=5=4.  With 11 or 12 diamonds, between dummy and my hand, a diamond lead is probably just a waste of tempo.  You are also unlikely to ever be on lead again, so either you lead a trump or partner's clubs.

3 5   50   BWP 18% BWS 18%  IAC 22%
If partner had not bid, this would be a no-brainer; Barry Bragin: "On a preference auction, lead a trump.  East might shed a club on the diamond ace, but cutting down spade ruffs in dummy is more likely to pay dividends."  Going with their general bridge instincts are:  Steve Gardner: "I hope that partner can play the ace and another trump."  Billy Eisenberg: "Partner is likely to have four-plus spades, so I'll try to protect his holding."  Eric Kokish: "The auction suggests that dummy will be short in declarer's main suit, so with the minors locked up (sort of) this feels right."

♣ 6   100   BWP 81% BWS 69%  IAC 67%
But partner did bid!  Jeff Rubens says "When in doubt, I have a strong bias toward leading partner's suit."  Similarly, JCreech: "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."  Larry Cohen: "I suppose I'll need to wait to find out why I shouldn't woodenly lead partner's suit."  Ron Gerard: "I can hear the post-mortem: Would you have led a club if I had bid diamonds?  I don't mastermind on opening lead."  Kerri and Steve Sanborn "Don't want to explain later to partner why there was an endplay after a diamond lead."  Carl Hudecek: "Partner bid clubs.  This is my only chance to put a club through."  Bruce Rogoff thinks "East has suggested a weakish six-five, but he was willing to risk partner's passing the double, which suggests a doubleton club."  Kit Woolsey: "East figures to be six-five.  A club through dummy may be necessary."  Adam Grossack says "I'm a simple man.  I'll lead through the dummy's clubs."  John Carruthers: "East who has shown 10-plus cards in the majors, is much more likely to be void of diamonds than North, who has shown six-plus cards in clubs.  I could lead a trump, but leading a club is unlikely to impact our ability to cut down spade ruffs."  Jason Feldman sees it as "The only chance to put a club through, but it wouldn't surprise if a trump worked best."  Masse24 "I'm not imaginative enough to come up with something better." but then Todd never saw a lead problem he has liked.  Though Danny Kleinman has the best reason to lead something other than partner's suit: "But if I hope to dump my current partner, the diamond king." 



This ends the discussion for the July MSC problems.  I hope you found it thought provoking.

We are a bit more than a week out of having the next set of answers due, so please partake.  As some are wont to say "Come on in, the water's fine."  All participants are welcome, and despite the Panel's opinions, there are seldom any truly wrong answers; in most instances, you will find at least some in the Panel or at least some percentage of the solvers that will agree with your choice unless you severely misread the problem.

What call do you make?

Partner is clearly short in spades, but is that a good enough reason to pass his double?  The AQ of hearts and the five spades will certainly work on defense, but the !D K is far less certain given that LHO opened the suit.  There are offensive possibilities as well, but everything depends on fit, and how you proceed will matter.  However, that is also one reason why it is incumbent on you to act with a good hand and a void in the opponent's suit; the chance that partner will choose to defend in their best suit works against them making a reopening double.  How best to continue?

4 ♣   100   BWP 41% BWS 17% IAC One solver
A jump in clubs may an optimistic view of the offensive values. Steve Gardner says "Partner's shape is pretty much known, but where are his high cards?  I can easily hit a dead minimum:  ♠ x    Kxxx    Axxx   ♣ Qxxx, or maybe I will hit the daily double:  ♠ -    10xxx    Axxx   ♣ Axxxx.  Four clubs ain't exactly science, but it does give partner an out." Exactly!  The temptation to pass abounds.  Robert Wolff: "Pass will be the majority choice, but it would be partner-baiting."  Phillip Alder: "At matchpoints, I would think about passing but probably would reject it."  Chip Martel: "Partner can have a stiff spade (e.g., West/East are 3=4=5=1/4=3=3=3), usually will have none (and fewer than five hearts) so there are great prospects in clubs (possibly even slam).  But North might be 1=4=5=3, so I can't drive to game."  Ron Gerard: "Wimp of the Month Award.  For my own money, I might pass, but with teammates in the picture what is the chance of even plus 300 vs. only a partial?  More likely it would be plus 100 vs. a club game (when declarer scrambles six trumps and a winner or five trumps and two winners)."  Gary Cohler: "Tempting to pass - if partner has a spade, it could be bloody; however, the opponents might make or be down one when we can make five or six clubs.  Four clubs seems middle-of-the-road."  Nonetheless, Bruce Rogoff: thinks it is "The value bid for clubs.  Partner's club length is very important.  I'll bid six clubs over four spades or cooperate over four diamonds.  Passing does not appeal, as long, strong clubs opposite might produce a disaster.  Notrump looks foolish, as we might be off the whole diamond suit.  Imagine:  ♠ -    KJxx    xxxx   ♣ AKxxx."  However, BluBayou has his rose-colored glasses on:  "My May First shot of leaving in the double of 2 spades is hereby cancelled!.  Take out a deck of cards and give partner 9-10 pts , void in spades and four (five??) hearts and 9 minor cards--preferably  4 diamonds and 5 clubs. ( My first effort gave our side a slam in clubs, when Lefty happened to be dealt  Kx in clubs! ). Meanwhile, the opps  had an easy ride to 7 tricks in their 2 spades.  Really, pard is bound to have very decent clubs since his hearts are Kxxx or worse and he has zero spades."  And Barry Bragin: "I don't want to make it easy for West to show his six-card diamond suit with 3=3=6=1."

Not giving any leeway to pard.  Carl Hudecek thinks "Partner passed one diamond with spade shortness, and it behooves me to bid a rounded suit.  I visualize the likes of 0=4=5=4."
Zia "Don't like defending when partner is void.  I half expect a raise, but that might require five clubs opposite, and North is more likely to be 0=4=5=4."  John Carruthers "Can't construct a hand for partner that would not provide a play for this."  Iain Sime feels "Partner is probably void of spades.  I have a badly-placed kingleton and (most importantly), a fit.  We might make a minor-suit game with three losers if West leads a spade."  Sami Kehela: "Passing may not yield enough, and obviously three clubs would be too little.  We may well have a slam."

Flexing his muscles, Adam Grossack bids "To force to game and perhaps more in clubs.  I hope partner has a spade void."

Is it wimpy or sensible to bid 3 !C?  It is matchpoints, after all, where going plus is often king.  Kit Woolsey says "Partner almost certainly have at least four clubs; so passing the double would be too greedy when we have a comfortable plus score available.  I may get a shot at a higher level, but the hand looks too junky to move toward game."  Jeff Rubens thinks it "More likely to make than two notrump; doesn't lose as much as passing when wrong; the downside of underbidding game prospects is small when we have a misfit, a weak long suit and apparently-awkward entry situation at notrump."  Masse24 feels "Partner has some sort of 0=4=5=4 opening hand or close. Not going to punish him for the prebalance."  JCreech finds "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."  While Danny Kleinman says "Shift-directing, to tell myself which suit to shift to after the king of diamonds holds trick one in three spades doubled.  I see neither game for our side nor a sufficiently large penalty against two spades doubled."

Pass   70   BWP 19% BWS 24%  IAC 56%
Rolling the dice.  Kerri and Steve Sanborn: "Reopening doubles can be interesting.  You win some, you lose some, and some get passed out.  If LHO is supposed to have four spades, passing would have less going for it.  On the flip side, picture partner with 1=4=5=3 and decent values."  Hoki: "They do say that trump leads are mandatory against doubled suit partscores. With partner passing in the direct seat I don't expect that our side can make game - and the hand does meet the rule of nine.Bart Bramley thinks it "Could be down a lot when we have no game (or would pick the wrong game).  For example, give partner: ♠ x    Kxxx    Axxx   ♣ Axxx and LHO 3=4=5=1."  Eric Rodwell feels the "Defense looks promising, especially if the opponents have only seven trumps.  It is not certain that pard has four clubs - he might have opening-bid values with four hearts and primary diamonds."  Eric Kokish: "The big club fit and golden red honors suggest that our potential is quite high, especially if North has no spades, but how we could approach five clubs or six clubs without giving up on three notrump is complex.  On defense, we might get 300 when the wrong game would fail our way."  WackoJackthinks "Partner has likely 1444 distribution, say ♠ x, KJxx, Axxx, ♣ AQxx.  If as good as this we will take 2♠ + likely 3, +2♦ + 1♣ = +500 more than game our way.  If less then we will still get more than the possible part score."  Larry Cohen "If we have a game, we might collect enough to make up for it.  We could have a club slam but also could have no game and score 300."

DickHy says "This looks to be a 20/20 hand.  What’s better, declaring 3 !C or defending 2 !S x?"  Of course, this presumes that partner has a spade stack and would pass the double, but that is also a risk when you double with a void in the opponent's suit.  And perhaps others are valuing the hand and the choices differently, but I do believe that this is a 20/20 hand at the table; so what is your poison?

A free-bid at the three-level is not chopped liver.  And the natural new-suit bid draws a tie for the plurality of Panelists.  Larry Cohen feels the "Need to get the clubs into the game before West jumps to four spades.  We could easily have a club game or slam (consider ♠ Jxx    x    Axxx   ♣ Kxxxx)."  Similarly, Masse24 is "Clearly showing extras. The quality of the club suit is such that I prefer to show it rather than double."  Gary Cohler "Could double, but I'd like to get my suits in.  I can bid four notrump over four spades if necessary."  JCreech: "I think just freely bidding at the three-level implies extra values.  Perhaps not quite as good as this, but close."  Zia is "Preparing for the inevitable spade raise.  I can later double or bid four notrump to set up a force.  Four hearts now would require bidding five clubs later."  Robert Wolff is "Hoping to be able to bid four hearts next."

If 3 !C feels a bit of an overbid, 3 !H feels a bit of an underbid, but how can you argue with a nearly solid six-bagger.  As BluBayou puts it, "A stretchy jump-rebid to 3 !H  becomes a very comfortable  non-jump, when opp intervene, If you're needing to bid a third time then  "hearts, hearts, clubs"  is better than some alternative."  Bruce Rogoff says "Some number of spades will come back, but how many?  ... this will clearly work out best if I'm able to bid four clubs next.  If East-West bounce to four spades, I'll risk a double and hope."  Danny Kleinman thinks "Clubs can wait until the five-level; I don't expect to buy the contract any cheaper."

Double   90   BWP 26%   BWS 37%  IAC 44%
The most flexible bid, but fraught with risk.  Nonetheless, we should not forget that this problem comes with a hint.  It is here we find the plurality of solvers plus a tie for the plurality of Panelists.  Phillip Alder "You led the witness.  If partner passes, maybe we will get 500.  If he tries three diamonds, I will, rightly or wrongly, continue with three hearts."  Steve Gardner says "Easy, because I want to describe a hand where I'm able to play in any of three suits.  If possible, I will later compete with four hearts (or, should the opponents jam the auction, with four notrump)."  Iain Sime points out that "With a strong hand and no clear direction, one conserves space."  WackoJack thinks "We could only have an 8 card fit.  Partner could have a 3244 distribution; say ♠Qxx, xx, Qxx, ♣Kxxx.  If I double could we still get to 4?  I think so.  Partner will bid 3♣ and I will rebid 3.   And partner will raise to 4 with a doubleton.  I note that opps having a 10 card ♠ fit and we having an 8 card ♣ or ♥ fit then total tricks = 10.  So if we can make 4 then opps should go 2 off in 4♠ and so we have a 500 penalty which is more than our nv +420 in 4."  Ron Gerard: "To prepare for the spade raise.  I will bid the minimum number of hearts next.  If I were to bid the hearts now, I would not be as well placed when three spades came around to me."  Barry Bragin is "Driving to game with a four-loser hand.  I will correct partner's three-diamond bid to four hearts, trusting North to bid on with 3=0=5=5 or similar. ... Doubling now sets the stage for partner to compete (or, double) if West preempts."  Eric Kokish writes: "West will raise with support, so worrying about a penalty pass by North is not worth the trouble.  Hearts often won't break well, so jumping to four hearts could be silly while six clubs could be excellent."  Kerri and Steve Sanborn: "We would be surprised if LHO and partner passed.  If LHO will raise spades, we want to encourage partner to chirp freely." 

3 ♠   70   BWP 19%   BWS 3% IAC No solvers
Some tried the cue-bid in an overt attempt to get to notrump from partner's side.  Bart Bramley feels the hand "Too risky to double.  Three spades aims directly at the two most likely games, with a shot at clubs if partner bids the suit."  Sammi Kehela: "This is a hand of quality, worth a slight overbid."  Eric Rodwell: "Short spades (likely void, since no double) and extras.  If East-West bid four spades, pard's pass won't be forcing, so he will need to act with values or appropriate shape."  John Carruthers says "I'll aim for clubs or hearts, depending on partner's call."  Kit Woolsey "We could belong in clubs, but with this heart suit it looks better to describe the hand-type with three spades.  Partner can bid three notrump, four hearts, or even four of a minor, all of which will likely work well."

4    60   BWP 15%   BWS 7% IAC No solvers
To me, this was a surprise from the Panel, though if this were asked of the BBO general set of players, I would expect a majority; a fine six-bagger in a competitive auction - jump to game in that suit, maybe even open 4 !H.  However, the thinking of the Panelists making this choice are similar (just a level higher) to the arguments for bidding 3 !HCarl Hudecek says "Over the opponents' four spades.  I will bid five clubs (because of the vulnerability)."  Chip Martel thinks "Partner might interpret three spades as 0=5=4=4.  If North does not double four spades, I will bid four notrump."  To Jeff Rubens, the bid "Rates to be right on average if West doesn't bid, and it's a reasonable description of the hand if he does."  For Billy Eisenberg the bid is "A standout.  I will be comfortable with whatever comes next."



This ends Part 2.  Again, I hope there was something of interest or use to you in this discussion.  Nonetheless, I want to remind everyone that we are nearly 2/3's through the month, and we need to hear from the IAC solvers on how they view the new problems.  All are welcome, and if you explain your thinking a bit, it helps everyone.

Problem A 5 !D  (CCR3, BluBayou, Hoki)

Imps  Neither side vulnerable

What call do you make?

You have 17 HCPs with nearly perfect shape for a takeout double when RHO opens 3 !D.  However, partner threw the ball back into your court by cue-bidding 4 !D showing at least two places to play.  You do have both majors and he has at least one, so you have several options available. 

5    100   Bridge World Panel (BWP) 48%   Bridge World solvers (BWS) 38%  Intermediate-Advanced Club (IAC) 1 solver
Nearly half of the Panel threw the ball back to partner.  As Hoki puts it:  "The plan is to settle for slam in the suit of partner's choice."  Robert Wolff describes one variation: "Then bid six diamonds over five of a major as a general grand-slam-try. ... Few partnerships have discussed what six diamonds means here."  While Bart Bramley describes another:  "Driving to slam.  Will raise a major to six.  We lack the tools to reach seven or to avoid six."  And Chip Martel offers a third: "May drive us too high, but four of a major could miss a good slam.  I will pass five of a major."  Maybe a slam is not automatic after all.  Oh well, back to the slammers.  Bruce Rogoff feels the hand is "A little too strong to settle for game.  The risk of going down at the five-level is far lower than the likelihood of missing a cold slam by going low."  Kit Woolsey: "Picture North with e.g.: ♠ Jxxx    AKxx    xx   ♣ Kxx, where playing slam in the four-four fit is critical.  This sort of layout is very likely; I will raise five hearts to six."  Gary Cohler: "Hate to hang partner, but the right 10-count produces a slam,  Might need to reach hearts if we need a club pitch."  Aye, that's the rub; as Iain Sime says "If partner stretched to find a fit, five hearts may prove tenuous, but North would often pass four hearts and miss a slam."  Nonetheless, several point to the extras that need to be shown.  Eric Kokish: "Too strong for four hearts; four spades would deny four-plus hearts."  Kerri and Steve Sanborn: "North was willing to commit to the four-level, so it is important to show the extras."  BluBayou: "A simple jump to  5 !S  looked fine to me at first, but why shouldn't that show an even bigger hand  with two diamond losers??"

4 NT   40   BWP 1 Panelist   BWS 5%  IAC 22%
Some take the bull by the horns.  Sami Kehela describes "A cunning strategem designe to determine how many aces partner holds."  WackoJack says "I would like to ask partner how many Aces.  If 2 then I ask for kings.  How do I do that? I think 4NT must be asking for aces.  So 4NT."  While DickHy is concerned about the meaning of the bid:  "4 !D shows both majors, so we’re playing in spades.  4 !S seems wimpish, as I would have bid the same with KQxxx in spades, but how is slam best investigated?  5 !D or 5N seem blind shots. What would 4N be?  If it’s Blackwood, I can bid 5 !S, 6 !S, 5N after 5 !C, 5 !D, and 5 !H respectively.  That seems ok.  If 4N is summat else, I'll get a kicking -- two actually, one from myself too"

4 ♠   80   BWP 26%   BWS 28%  IAC 33%
What is partner showing with his 4 !D cue-bid?  Some throw out some possible hands to demonstrate the variety that partner may have.  Danny Kleinman: "With significant extras and an unexpectedly good suit, I'm tempted to do more.  But North might hold, e.g.: ♠ xxxx    xxxx    Axx   ♣ KQ."  John Carruthers: "Not smart enough to distinguish between: ♠ Jxxx    AK10x    xx   ♣ Kxx and: ♠ Jxxxx    AK10xx    x   ♣ xx.  Very tricky to reach hearts."  As Zia points out: "Underbid?  Misbid?  Maybe both, but a plus score.  Four diamonds is wide-range."  JCreech settles for the obvious: "Too many things to show, so I will show that I have a fine suit and that I have extras.  Anything beyond that partner will have to ask."  Masse24 feels "Partner may simply have a choice of games for his 4 !D call. I've already shown extras by doubling at the three level. While I do have a bit more, I'm going to allow partner to make the slam move."  Phillip Alder argues that the bid "Could cost a slam, but perhaps partner overbid to ensure finding the right fit."  Eric Rodwell agrees "We could have a good slam, but partner might bid on.  He could be stretching to find the best game with four-four majors and an 8-count or even have 3=3=2=5 and about a 10-count."  Carl Hudecek settles:  "Many North hands won't make slam, many more make us laydown for slam.  With slam interest, partner can bid again."

5 NT   60   BWP 15%   BWS 6% IAC No solvers
Some offer a choice of slams immediately.  Steve Garner says "I expect partner to hold a minimum game-force with both majors, but he might have a four-card major and longer clubs. I'll try five notrump to ask partner to pick a slam."  Barry Bragin is "Offering a choice of strain caters to North's 2=4=2=5;  I will correct six clubs to six hearts."  Adam Grossack: "I want to try to reach six hearts, in case North holds, e.g.:  ♠ Jxxx    AKxx    xx   ♣ Kxx.  I'll bid six hearts over six of a minor.  This highlights my lack of first-round diamond control."  And Larry Cohen entertains higher yet aspirations: "Too strong for only four spades, and five spades might be interpreted incorrectly.  I'll leave room for partner to bid six diamonds to try to reach seven."

5 ♠   50   BWP 7%   BWS 6% IAC No solvers
While others are still only inviting, but is the meaning clear?  Billy Eisenberg thinks so:  "Natural seems a logical meaning."  And Jeff Rubens seems willing to play in five in spades, but forces partner to choose a slam alternative in another strain: "With an ace-value extra, a strong suit, and slam-oriented values, a positive move is necessary.  North knows I am prepared for a run from spades."

You have opened 1 !D with a traditional, square minimum, and partner has responded with a game-forcing 2/1, one suit below yours.  Do you show support, your shape, or something else?

2 NT   90   BWP 41%   BWS 38%  IAC 56%
A majority of the IAC solvers preferred to show shape on this hand, with roughly 40% of the BW Panel and solvers joining them.  Zia declares "A weak notrump is still a weak notrump, positional or not."  WackoJack writes "I have a balanced 13 so I must show that by bidding 2NT.  OK what could go wrong?  Suppose partner had ♠x,  AQx, Qxx, ♣KQJxxx.  Then I would expect him to bid 3♣ and we get to the reasonable 5♣ contract.  Suppose partner had ♠Jx, Axx, Qxx, ♣KQJxx and you raise to 3♣. Then only poor bidding will get you to the making 3NT.  So 2NT it is."  Robert Wolff: "I prefer this general approach."  Chip Martel: "Best to show the general nature of the hand rather than make an ambiguous bid such as three clubs.  Might wrongside three notrump, but may need to protect spade queen."  Sami Kehela:  "It would be less vexing if you were to provide more of these uncomplicated problems.  A good case for the feeble notrump."  Gary Cohler: "A flat, minimum hand.  Worry about stoppers later rather than distort now."  Eric Rodwell "I don't love it, but I must define the hand-type.  Strongly dislike three clubs with only three."  John Carruthers: "Describing the nature of the hand is more important than trying to place the notrump declaration 'correctly.'"  Adam Grossack: "Depends on style, but with 4-3-3-3 opener should bid notrump.  Maybe partner has three low hearts."  Larry Cohen: "Partner won't bid three notrump with a singleton heart.  Describe the hand-type and don't distort.  If partner has ten-low-low or jack-low-low of hearts, someone must bid notrump."  Kit Woolsey: "A perfect description of hand-type.  If there is a heart problem and the contract is wrongsided, too bad.  Anything else would be a distortion."  This time Hoki is determined to follow the Panel: "Normally I would raise to 3♣ and move on, but these panelists seem to prefer to show shape and not care about such piffling matters as stoppers."  But DickHy is concerned about possible flaw in the auction "Presumably 2 !C may not be a real suit.  Qxx isn’t a stop but I’m not promising one with 2N, a bid which describes the hand well."  Yes, Dick, Qxx is not a full stop in spades, but you seem to be neglecting another unbid suit, with even less at the top.  It is hands like this that have convinced that it is often best to get your hand and shape out of your system at bid one; I have been a weak notrumper for nearly 40 years, and reminded why nearly every time I play strong notrump.

3 ♣   100   BWP 44%   BWS 48%  IAC 33%
For those who raise, Carl Hudecek brings out an important point: "A KISS from me.  The bulk of the hand is in the minors."  Bruce Rogoff reminds us of our heart problem:  "This can still take us to notrump.  Bidding  notrump now would condemn us to that strain when partner has a balanced minimum with two low hearts."  Eric Kokish: "Good layout for an artificial two hearts to show a balanced hand.  Don't like two diamonds when it's not necessary."  Kerri and Steve Sanborn has read the system notes:  "Per system, opener may raise on a minimum."  And Jeff Rubens is hardly ruling out the higher scoring option:  "Looks best for making a sensible decision about three notrump."  One way to think of it is Iain Sime's "Set up a base camp, then explore."  JCreech thinks "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."  Ron Gerard says "I like to have more (in high cards or in clubs) for this raise, but I don't see what two diamonds would accomplish."  Bart Bramley considers "Two notrump is tempting, but that would be more of a matchpoint move.  Raise with support and let nature take its course."  Masse24 thinks the problem to be "Somewhat of a system agreement question. I believe that over 1 !D a 2 !C response shows 5+. A 2 !D rebid in this auction absolutely shows 5+, so that is out. And although my shape is right for 2NT, my "stoppers" are lacking. So . . . support with support."  Barry Bragin: "The most likely final contracts are three notrump and five clubs.  Every effort must be made to mae partner the declarer."  Steve Gardner: "I feel a little guilty about misdescribing the hand-type, but raising may improve partner's hand evaluation.  Change the club ace to the spade ace and I'd bid two notrump."

2    50   BWP 15%   BWS 9% IAC No solvers
Although this response was not on my radar, Danny Kleinman has reasonable rationale: "After adopting this policy, I learned that Al Roth may have devised it first: two diamonds shows 13 cards and nothing special to say.  I'd bid the same way if the eight of diamonds were the eight of hearts."  Billy Eisenberg makes the choice largely for the same reason that many chose to raise: "Two notrump looks worse with such weak majors."




Problem C  3 !H  (VeredK, BluBayou)

You have opened and rebid your nice, but less than wonderful six-card heart suit, while partner has put on a game force with 2 !C, and followed that with 3 !D.  How to proceed?

3    100   BWP 37%   BWS 28%  IAC 22%
The easiest thing to do is soldier on; you don't particularly like your fit with either of partner's suits, and yours is headed by KQ10.  Jeff Rubens thinks "The suit is strong enough for trumps opposite two low or a singleton honor, so it would be misleading to bypass it."  Ron Gerard: "Need to let partner know that singleton jack is okay trump support.  If we need to play in three notrump from my side, I can bid it next over three spades.  Supporting clubs would be premature until North clarifiess his club intentions."  Kerri and Steve Sanborn say "No reason to take up extra space when we have a suit playable opposite honor-doubleton (or even stiff ace) if partner has two low spades."  Billy Eisenberg thinks it "Obvious to show the sixth heart."  Danny Kleinman: "If I don't bid this, partner will never imagine that I have six hearts."  BluBayou: "12 points,  pretty-good 6-card suit  looks like "1H...2H...3H"  to me.  no need to commit to some half-baked third bid when pard can steer us to port with HIS 3rd bid."  However, Jason Feldman says "I'm unsure of the best game; this leaves room to get more information from partner."  Similarly, Chip Martel writes: "Must show a good six-card suit lest we miss a good four hearts.  Partner could be 3=1=4=5 with three low spades, so I also must leave him a three-spade bid to let me bit three notrump."  Many are thinking of notrump.  Barry Bragin points to a past problem:  "Similar to November 2021 (E), where three notrump will be best only if partner can bid it."  Larry Cohen: "Don't want to bypass three notrump.  If partner bids it now, I will pass.  Think."  DickHy "Qxx isn’t a stop and I would be promising one with a bid of 3N.  There is the 'I’ve shown a stop in the bidding so don’t need one in my hand' approach, I guess.  My 2 !H may not show 6-card suit, 3 !H would.  Partner has choices then: 4 !H (with two hearts), 3N with a spade stop, 4m with more shapely minors and 3 !S asking for a spade stop.  With the last two, I’ll sign-off with 5 !C."  Eric Rodwell: "The spade stopper is tenuous; if pard punts with three spades, I will bid three notrump."

3 NT   50   BWP 15%   BWS 13% IAC No solvers
Taking a leap of faith that Qxx will be a good-enough stopper in spades are the three notrumpers, but those making the bid clearly have issues.  For example, Carl Hudecek says "I would like the hand more for a club contract if it had another diamond, or if my spade honor were the king."  Adam Grossack thinks he's sending a message: "Don't like the hand; want to make a negative noise."  And Phillip Alder is trying to ask a question:  "How many spades do you have, partner?"

JCreech describes the fourth suit in this auction as "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."  Similarly, John Carruthers is "Marking time.  If North bids be yond three notrump, I'll support clubs."  Bart Bramley says "Keeps all viable strains in play.  Partner will know that a partial spade stop is enough, since he couldn't bid two notrump last round."  Kit Woolsey thinks "Three notrump is still in the picture; I will pass if partner bids it; otherwise, we will reach clubs or hearts."  Masse24 is "Showing something, but not enough to bid 3NT."  WackoJack: "First of all, after 1-2♣, I believe that if you rebid 2 in this position, then you are showing a 6 card suit. You have good alternatives with only a 5 card ♥ suit.   With say ♠xx, KQJ10x, Axx, ♣Kxx,; then you  would raise to 3♣.  With say ♠Qxx, ♥KQJ10x, ♦Ax, ♣Jxx you would rebid 2NT (similar to problem B) So when partner bids 3, he has longer clubs than diamonds and not 4♠ and likely singleton .  So 3145, 2146  or perhaps even wilder.  So I bid the 4th suit 3♠ and partner will bid 3N with 3145 and a partial ♠ guard. Or 4♣ with 2146.   If I bid 3♠ now partner should be able to supply the answers.  Partner with a strong hand say: ♠Ax, x, KQJ10, ♣ AKQxxx will bid 4NT"  Hoki: "I'm reluctant to bid hearts again since that would show seven of them."  Iain Sime wants to "Pass the buck.  I fear three quick losers in a club contract."  And Alan Sontag anticipates:  "I can hear partner now: 'When did you intend to support my suit?'"

Now we hear from those that did raise partner; violating Hamman's Law notwithstanding.  Gary Cohler thinks "Three spades will be popular, but it tells nothing; three hearts would prolong the issue.  With a real club fit, I like the clarity of four clubs."  Zia is in sync with Iain, but making the other decision:  "Seems North is looking for support, and three spades would be a bit of passing the buck."  Steve Gardner believes that "Three notrump may well be best, but four hearts or five clubs might be better.  Why not clue partner in about the club support."  Robert Wolff: "I'll pass five clubs from partner but head toward slam after most alternatives."  I think Eric Kokish's arguments are the best for this choice: "Three spades could put us in three notrump opposite weak spade length and will often catch two-card heart support, but supporting North's first suit when a high club contract is still in play feels cleaner."



This concludes the first part.  I hope you found it interesting and/or useful.  For those who may be unaware, Eric Kokish recently passed, so his contributions to MSC will sometime in the coming months.  His contributions are staggering to the bridge world and he will be missed.

My initial thoughts:

Problem A:  4 NT  It sounds like we have a double fit and partner has a massive hand.  I essentially need information on certain key cards, that 4 NT is likely to provide.  With hearts as trump, a 5 !S response normally could be a concern, but I have the queen and enough length that partner is highly unlikely to make that bid.  If we have all of the keys, then I can find out about the two minor suit kings for a possible seven.

Problem B:  4 !D  Where is my weak NT, so I can get this hand described in one bid, then just follow instructions.  Partner sounds distributional - at least 5-5 - aces play well in suit contracts and I have three diamonds with partner.  May as well raise; multiple single stops don't make me want to follow Hamman's Law.

Problem C:  3 NT  I'm not really caring whether this shows a heart stop and a smattering of values, or is asking partner to bid a minor unless he has length in spades, and suppressed the suit to ask me to show a preference.

Problem D:  Pass I wish I had bid 2 !D and then doubled, but I didn't.  Now I I don't think I have enough to bid either 2NT, trusting partner, 3 !D on my own, or even double to see if partner wants to convert.  I am now in a wait and see of what partner wants to do.

Problem E:  4 !S  No good bid available, but a great hand.  I can easily visualize spade shortness in partner's hand, so the diamonds are likely to be real and slam possible.  May as well let partner know I have a good hand.  I feel stuck now with a nebulous cue-bid, and maybe time will give me better perspective.

Problem F:  f - DAD  I like getting my hands described quickly.  I have a decent 7 with a double stop in the opponent's suit, so I want to bid 1 NT immediately and Disagree with pass.  Partner reversed and I have stoppers in both of opponent's suits, so I Agree with showing the stoppers.  Now partner is showing at least a powerful 5-6 in the reds.  Should I show a preference with my pair of deuces or push for the notrump game?  It is close, but I think the notrump game is more secure than the diamond slam, so I Disagree.

Problem G:  5 !D  I don't want to stop short of game, but partner may have felt a lot of pressure to double with only three hearts.  I have a better chance of surviving opposite xx in diammonds than opposite AKx in hearts and needing to ruff one or two spades.

Problem H:  !S 9  A trump seems safest.


Sets like this one make me see the wisdom of Ken Berg in opting out of MSC.  Still would love to hear his comments though; always thoughtful.

Blu,

Passing 1 !S makes a lot of sense.  The best reason with this hand to bid is to block the opponents from coming in cheaply.  That was Robert Wolff's point when he passed 3 !H:  "Which I might have done last turn but didn't lest West enter in clubs."

If you are looking for a game, this 6 HCP rag is just not likely to produce one unless partner is either highly distributional or has a decently fitting 19 of his own.  In either case, opposite a passed hand, I would expect partner to jump shift to announce, "I want to be in game opposite virtually any ordinary response."  If partner is unable to jump shift, then I would be willing to pass.

That does raise questions about what a raise of a non-jump shift suit should mean. 

One possible meaning is Bobby's blocking bid; if that is the meaning, then no one should be taking another move beyond 2 !S

The other is you have a maximum for your minimum response; a value-oriented game-try.  This caters to hands that are short of a jump-shift and are inappropriate for opening a strong NT.  That seems to be the expectation of the North bidders, or they should be passing 2 !S.  If that is the case, why are so many of the Panelists accepting the game-try after making a blocking bid. 

Few things are worse in bridge than a partnership bidding at cross purposes.

This is a problem where I would really like to see the other hand after all is said and done.

June MSC SUMMARY (Part 3) – Danny Kleinman, Director

Problem G  1 NT  (Masse24, YleeXotee, BluBayou, CCR3, VeredK)

Matchpoints  North-South vulnerable
You, South, hold:

♠ K Q 10 4    K Q 10 9    5 3 2   ♣ A K

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

Apparently, this problem is a periodic test of whether the bridge community will open a strong four-card major when there is a convenient rebid.  The moderator, Danny Kleinman, provides a brief history:  "The original Bridge World Standard specified that a strong four-card major may be opened if a convenient rebid is available.  The current BWS restricts this leniency to third- and fourth-seat opening if the bidder can 'handle' the auction."  Danny anticipated a split between which major to open, but the schism emerged elsewhere.

1 NT   100   BWP 37%   BWS 69%  IAC 71%
The argument for this bid is entirely on the basis of HCPs and field expectations; because this is matchpoints, to open anything but 1 NT is viewed as swinging unnecessarily.  Frank Stewart writes: "So it's a maximum with both majors.  To open one diamond would be masterminding.  North would pass with a five-card major and a hand too weak to respond."  Joel Wooldridge thinks it "Seems normal.  One diamond might work well but might induce partner to overrate low diamond honors and overbid with queen-third there.  At imps, I might risk a one-diamond opening to reach a skinny game, but at matchpoints I want to preserve an average-plus."  Masse24: "KnR on this hand is 17.9. Knowing that, if we choose NOT to open 1NT, do we open 1C or 1D?  I think I’ll stick with the slightly overstrength 1NT."  Jeff Rubens points out that "If overstrength for one notrump, it is only by a sliver.  If I deemed this too strong for one notrump, I would need to bid something else, and I strongly dislike all four possibilities."  Kit Woolsey: "Even if something else is theoretically a bit better, which is a big 'if,' it isn't better by enough not to take what is certainly the field action."  Kevin Bathurst: "I expect many will open in a minor, and some days I might too as it's worth it (one diamond to preclude the lead would be my preference), but at matchpoints I'll try to start with the field and beat the other pairs later."  Robb Gordon says "Yes, the hand is too strong for one notrump.  But that is what the field will bid, and one diamond followed by a jump in partner's major would paint a poor picture of the hand."  BluBayou, in his own unique way, says what's the problem:  "A creative 1 diamond,  atruly antique 1 Spade??  WHAT else, seriously  than...."

1    50   BWP 11%   3% IAC No solvers
If not 1 NT, then  what?  What about a major, since that is what the problem was designed to elicit.  Doub and Wildavsky say "An unusual hand.  We could plausibly open one club, one diamond, one heart, one spade, or one notrump.  With 17.90 Four C's points, it is too strong for one notrump.  ...With one club and one diamond both flawed, we'll follow Kaplan's advice: 'Find your strongest four-card suit and pretend you have five.'  We will have easy rebids over any response and may rightside three notrump."  Nick L'Ecuyer argues "If there was ever a hand to open a four-card major in third seat, this is one.  It keep spades and everything else in the picture.  One notrump might be passed out when we have a much better partscore, perhaps even a game, in a major."

Note: All of a sudden, we start to see references to "Four C's."  This reference is to the evaluation computation that eventually is known as Kaplan and Rubens (KnR) hand evaluation.  Originally, the system was mentioned, not described, and was generally explained as Caution! Complex Computer Count, hence the Four C's.  That name did not catch on, but KnR did.

Since my original post, someone provided a link to a subsequent BW article that explained the calculations that went into the Four C's.  It can be found at https://roquibridge.files.wordpress.com/2013/03/cccc.pdf.

A more traditional approach would be to open a minor.  The advantage to opening one club is that partner's bend over backwards to keep the auction open in case the opener has club shortness.  Jeff Alexander writes "Too strong for one notrump.  I'm not worried about playing in my doubleton, because nobody passes one club."  Marc Jacobus is "Seeking a major."  Billy Eisenberg is "Hoping to raise one heart or one spade to three."  While David Berkowitz "... put myself in Zia's shoes and wondered what would he bid.  Voila!  If he would bid it, so must I."

1    90   BWP 33%   BWS 24$ IAC 29%
Of course, once you try to pin Zia down, he zigs or zags to avoid being predictable.  This time he went with the other minor.  Zia wants to "Stop the lead and find the major.  With queen-fifth in clubs and ace-fourth in a major, partner would pass a one-notrump opening butt could make game in the major."  Hoki has similar thoughts: "at matchpoints I'd like to explore for a major-suit first before committing to notrump with the hidden agenda of maybe deterring a diamond lead against a NT contract"  As does JCreech: "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."  Carl Hudecek thinks "This hand is too strong for a 15-to-17 HCP notrump.  Opening either minor will let us find a major-suit fit quickly.  I prefer one diamond, then jumping to four in the major partner bids.  Opening one diamond makes partner the declarer whether we play in hearts or spades."  Eric Kokish: "This hand looks better for suit play than for notrump, and I can handle any response, so I'll take a small gamble on finding a major fit as easily as possible.  Not to mention deterring a diamond lead when it matters."  Brian Platnick says "I hope partner will respond one heart or one spade, then bid four over my jump to three.  In my fantasy, east will cleverly underlead his ace of diamonds up to my partner's doubleton king."  Irina Levitina believes the hand "Too strong for on notrump, and one diamond makes it easier to find a fit in a major."  While Bart Bramley describes the situation as "Stayman.  ... we will find a major-suit fit immediately."  Drew Casen: "Four C's rates this hand at 17.90, but if I opened one notrump we might miss a superior partscore in a four-four major-suit fit."  Phillip Alder: "Four C's rates this 17.90.  One diamond makes it easy for partner to show a four-card major.  Majors and notrump may play better from his side.  My fear is being passed in one diamond."






Problem H !H A  (Masse24)

Imps  Neither side vulnerable
You, South, hold:

♠ 8    A J 10 9 8 7 3 2    2   ♣ J 10 9

SOUTH   WEST   NORTH   EAST
  4         Pass     Pass       5
  Pass      Pass    Double   (All Pass)
What is your opening lead?

What is the purpose of the double in this auction?  Sadly, no one on the Panel or the moderator mention the double as having any influence in their choice of lead.  They do not even treat it as a red herring; the Panel makes their lead determinations entirely on their hand and were not distracted by other considerations. IAC, though, did give some consideration to the double.

In the end, the Panelists split between two options:  try to cash the top heart, look around and try to figure out what to do next, or lead the spade, hoping to catch partner with the ace to give you a ruff on the way back.  There was talk of the club jack, but no one had a compelling reason to follow through with that option.

♠ 8   90   BWP 28%   BWS 44% IAC 86%
For those trying for the ruff.  Eric Kokish thinks "A heart ruff probably won't go away, and perhaps North won't play me for a second trump.  If North were unlikely to have spade strength, I would lead the heart ace.  A case can be made for the club jack, too."  Kit Woolsey considers the lead "A big winner if partner has the ace of spades, and might be good even if he doesn't."  David Berkowitz cites the old adage:  "If I don't lead a stiff, I haven't got one (unless I have no trumps, of course).  East's failure to double four hearts marks partner with spades (I hope)."  Jeff Alexander seems to have my luck:  "Singleton leads always work when made against me."  Bart Bramley: "When a singleton is an option, I usually lead it.  Also, leading it tends to clarify that it is a singleton.  The heart-ace could leave me guessing at trick two.  We will usually have another chance to obtain a heart ruff - if that's what we need."  Kevin Bathurst "Where are the spades?  I think declarer has some spade length, so perhaps he and my partner are both short in hearts.  I'll try for my ruff and hope that North can get a heart ruff later if necessary."  BluBayou expresses the futility of making leads:  "Lead stiff,  get ruff,  set up 3 pitches for declarer.  Oh well, sigh."  Two our IAC solvers were influenced by the double.  JCreech, for example, said "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."  While Hoki explains "my thinking (as misguided as I sometimes may be) is that a partner who wanted a heart ruff would not double because surely I would be expected to lead a heart normally without the double"

For those wanting a look-see.  Drew Casen says "When in doubt, lay down an ace and take a look."  Doub and Wildavsky explains further: "Ace-leads go way up in attractiveness against high-level contracts.  Assuming that the lead is not ruffed, the sight of dummy should give us an idea of how to continue."  Zia: "Partner figures to be short in my suit.  I probably will be able to figure out whether to shift at trick two.  I predict a huge majority."  Robb Gordon thinks "Partner rates to be short in hearts.  Let's see the dummy."  Robert Wolff is "Trying to stay in control."  Frank Stewart: "I am not sure how North intends to beat this, but surely he is short in hearts.  It will be unlucky if this is the only losing lead."  Phillip Alder points out that "If partner has more than one heart, he probably has the contract beaten on his own.  If the lead survives, I should know what to do next."  Marty Bergen believes "The best chance to know what to lead to trick two.  Of course, I will not be happy if I fail to retain the lead."  Carl Hudecek "I expect to win trick one, and then I can lead the appropriate singleton depending on dummy.  If the heart ace is ruffed and any other lead beats the contract, too bad."  Barnet Shenkin "Looks normal.  If it holds, I can shift or continue.  Partner may have a singleton or void in hearts and a black ace, or he may just be doubling on power."



Although choosing different leads, these two expressed similar sentiments.  Masse24 wrote "I’ve recently developed a distaste for lead problems."  Of course he has expressed displeasure with lead problems for some time, perhaps he noted something different with this month's problem.  Jeff Rubens points out that "Guessing among pleasant-looking alternatives is just as annoying as guessing among unpleasant-looking alternatives."  Most past problems have been trying to pull the best of bad alternatives, but this month, both viable alternative were good, and even the club was a good alternative, if only there were not two better ones.


This concludes Part 3.  Hopefully, you found something interesting or useful in these summaries.  Everyone should know that Todd did, and I learned some things during the preparation.  Don't forget to participate in the current MSC; we love seeing entries!
