Generally, Todd feels good if he receives 700 or more on a monthly problem set.  This month, 8 or the 11 participants exceeded 700.  Congrats!

Sorry that my initial responses are also my final responses.  Time slipped away.

Problem A:  3 !D  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.

Problem B:  5 !D 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.

Problem C:  1 NT  The right values and right-siding the hand still outweigh bidding or asking partner to bid the spades

Problem D:  Dbl  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.

Problem E:  2 !C 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.

Problem F:  1 !C  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.

Problem G:  3 !H  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

Problem H:  !D 8  The was a who knows sort of lead.  I eliminated the majors first - !H J may be important stop in that suit and I don't want to pickle any spade holding the partner may have.  The minors seem about equal in terms of both safety and aggession, so I took a bit of negative inference that partner did not double the club keycard response, and decided to play the 8 to be constructive if partner has something in the suit, and suggestive that I don't want the suit led back to me.

On F, I bow to the wisdom of others.  Opening 1 !S means I'll be re-bidding  !C at the 4-level (assuming partner will respond and/or there's a red suit overcall).  Opening 2 !C means re-bidding  !C one level higher.

66 hands don't come up often.  Mind you, I can't remember the last time I pre-empted 3 !C.  I can imagine a scheme for opening 66 hands 3 !C, responder relays, then 3 !H shows the reds, 3 !S the blacks and 3N mixed.  If opponents make a suit overcall, x would show the other colours and 3N mixed.  Over 3N, responder bids Hx/xxx suits up the line (while holding the Book of Common Prayer) [making dodgy bids is bad enough - suggesting systems is way OTT, Ed].

One way to keep the bidding lower if you fear a red-suit barrage is to open 1 !C.  This is from Danny Kleinman in last month's Panel:  "I object to the problem, because (a) with equal length and strength in the blacks, I would bid clubs ahead of spades, and (b) because of the rigid BWS requirements for a natural positive two-heart response.  Given the straitjacket, I would have risked a one-club opening."  Playing with Brian Platnik (after his Junior WC, but well before his more recent successes), the one thing he insisted on was that if I were 5-5 or 6-6 in the black suits, I was to open 1 !C.  This is hardly a consensus expert practice, but there are some who are rigid adherents.  Just as there are those who rigidly insist on the partnership opening a major whenever they have five or longer in a major (Steve Robinson quickly come to mind).  In MSC, to score well, you have to follow the Panel majority; at the table, you have to choose your own partnership path and follow it.

March MSC SUMMARY (Part 3b)– Eric Kokish, Director


Problem H  !D A  (None)

Imps  Neither side vulnerable
You, South, hold:

♠ J 6 2    J 10 4    A Q 3   ♣ J 8 6 2

SOUTH   WEST   NORTH   EAST
  ——      1 ♣       Pass      1
  Pass      3 ♣      Pass      3 NT
  Pass      Pass     Pass
What is your opening lead?

The moderator, Eric Kokish, made an interesting statement early in his writeup of this problem:  "Backing judgment is part of the expert's arsenal, but at imps the question inevitably arises about going out to try to win imps vs. staying even and trying not to lose them."  The comment was aimed at making a non-standard lead from a particular holding, but applies equally to trying to decide between an active vs. passive lead.   
 
4   70   BWP 1 Panelist   BWS 0%  IAC No solvers
Although it is not clear whether Andrew Robson aiming for an active or passive lead, he thinks "It's clear not to lead a black suit.  If I lead a diamond, which one?  The queen may be brilliant or very foolish; the ace is unlikely to work unless the suit is cashing, in which case it can proably wait, as clubs aren't running ... Leading a low heart will work when dummy has a singleton honor, or plays high from honor-doubleton."

J   80   BWP 18%   BWS 10%  IAC No solvers
Jeff Rubens "Not clear whether to prefer active or passive, but it looks right to hope that partner will lead diamonds."  Michael Lawrence: "On this sequence, a heart lead is often best.  Since North did not bid, there's little reason to look elsewhere."  Chris Willenken feels that "Without the surprise club holding, I would lead the diamond ace, going for fast tricks.  Here, though, the heart lead might be constructive if partner has strong hearts, and it might be a winning passive lead if the bad club break defeats a normal game.  The main danger is that partner may erroneously return a heart later."  And Billy Eisenberg believes the lead "Least likely to promote an extra trick for declarer."  While David Berkowitz excludes the alternatives: "A diamond lead would be too unilateral, and partner didn't bid one spade."

♠ 2   60   BWP 14%   BWS 39%  IAC 90%
The solver plurality was to lead a spade.  Most Panelists avoided the lead because partner did not overcall the suit, but then partner could have overcalled at the one-level in two other suits and did not.  Come on, there must be a better reason not to lead a spade.  Dan Gerstman's point is well-taken: "Anything could be right - well, maybe not a club.  Partner, nonvulnerable, passed ober one club.  Seems like a deal where losing a trick on the lead could be declarer's ninth."  Masse24 thinks the lead "Should be the most popular choice by both the panel and solvers. Am I missing something?"  Todd, only half right this time, so perhaps you are missing something.  Hoki: "by elimination"  CCR3: "decided to go passive this time."  WackoJack: "Speculative 2 !SGeorge Jacobs mentions a good point:  "I'll be on lead three times.  I hope we have more spades than the opponents.  If I were a European, I would lead the spade jack.  Maybe I should anyway; Zia will."  While JCreech says "I still like my original idea, but chickened out.  No good reason other than to follow the crowd."  You followed the wrong crowd for a good score, Jim.

A   100   BWP 39%   BWS 19%  IAC No solvers
So what was Jim's first thought?  JCreech: "I suspect I need to produce a Deschapelles coup, so I will look at dummy to decide which suit I need to lead to attack dummy's entry."  Jim is the only one to mention Deschapelles, but why couldn't dummy be something like ♠ x    xx    Kxx   ♣ AKQxxxx, hoping the clubs run or the diamond is an entry.  If you wait to attack the diamond entry, it becomes too late.  Richard Colker identifies two other ways the !D ace could win: "Any suit but clubs is possible.  A major could catch partner with four including one of the top honors and at least one important intermediate (ten or nine), but the diamond ace has two ways to win; partner could hold the king or jack with length; or dummy and North's signal could clarify which major to attack."  Echoed by Philippe Cronier: "The best way to know which color to play at the second trick, diamonds frequently being the right one."  Carl Hudecek argues that "This would clearly be the correct lead if the club jack were the club three.  Since I can stop clubs, I will feign desperation to convince a shrewd declarer not to finesse in clubs."  John Stewart: "Spade unlikely to win, as partner didn't overcall."  Bart Bramley: "Not a spade, since partner didn't bid the suit, so I'll hope to hit his diamond length.  Not the queen, since I might spear the king with the ace-lead."  Mats Nilsland: "I must lead something."

Q   90   BWP 25%   BWS 15%        .  IAC 1 solver
The Panelists going with the !D queen lead are largely hoping to find partner with Jxxxx in the suit.  Kit Woolsey: "If I catch the magic jack-fifth in partner's hand, declarer won't know to duck the king of diamonds."  Danny Kleinman "A quick guess:  attack dummy's diamond entry.  Won't it be nice to find partner with jack-nine-fifth?"  Janice Seamon Molson: "If declarer has king-third, he can comfortably duck after the ace-lead and continuation.  It seems unlikely that we can beat the contract in another suit.  Ace would have the advantage of letting me see dummy."  BluBayou seems to be looking to hit partner: "The mission here is to build four+ cashers asap, before jump-rebidder's club suit is established--not to be passive.  I believe the popular low spade is basically passive"  As is Michael Becker "I don't have a long suit to establish, but partner might.  I'll do all in and bet on diamonds.  I prefer the queen to the ace, because there are layouts where declarer wins with the king when ducking would work better.  Also, I might catch king-low-low in dummy and ten-low (-low-low) in declarer's hand.  The ace works better when dummy has stiff king or I can guess a major-suit shift that defeats the contract."  in the end, Robert Wolff's observation may be most apt: "I am trying to be either a thoroughly-modern moron or a genius."



This concludes the summary.  Hopefully, there will be something of either use or entertainment gleaned from the effort.  Please join in the discussion for next month's MSC (any form of participation is most welcome, though as the one summarizing, I look forward to the commentary to help shape discussion).    Until next month ...

March MSC SUMMARY (Part 3a)– Eric Kokish, Director


Problem F  4 !S  (CCR3, VeeRee, VeredK, BluBayou, YleeXotee, BabsG, Masse24)

Imps  Neither side vulnerable
You, South, hold:

♠ —    A J 10 7 4 2    A 5 3   ♣ A J 9 4

SOUTH   WEST   NORTH   EAST
  ——      ——      1 ♣        1 ♠
  2        3 ♠       4         Pass
   ?         
What call do you make?

Partner opened your second longest suit, then supported your longest suit at the four-level, and the opponents are both bidding my void suit. And let's go back to partner's 4 !H bid, when you bid 2 !H, partner was forced to bid, but when West bid 3 !S, his heart support was now freely given, implying extras.  A slam move seems right, but which one?  Part of the problem is that you have all of the first-round controls, and partner may be reluctant to show a second-round control at the five-level.

5 ♣   90   BWP 11%   BWS 5%  IAC No solvers
To bring partner into the picture about a double fit, you could bid clubs.  Michael Becker describes the situation well:  "I have so much to say and so little room to say it.  A grand slam in clubs is in the picture.  I don't expect partner to cooperate immediately, but when I bid five spades next round (and I hope six diamonds later), North will get the idea that level and strain are issues."  Michael Lawrence thinks the bid is "Forcing.  Will follow with five spades."  Bart Bramley: "We don't need much to make seven, especially in clubs.  Partner, with no aces, may be uncooperative, but when I drive to slam, he may get the picture.  Five spades would be an exclusion-ask, which wouldn't tell me what I need to know."

5 ♠   70   BWP 18%   BWS 5%  IAC No solvers
Several Panelists try exclusion.  Richard Colker "I'm hoping this is the Exclusion Zone.  After a one-key reply, I'll ask for the trump queen, enabling partner to bid seven on long clubs and or both minor-suit kings."  The problem is, as pointed out by Eric Kokish, our moderator, "... although many would treat five spades as Bramley suggests, BWS does not."  The legitimate inference is raised by John Stewart:  "Best I can do.  Four spades wouldn't help partner, who holds no aces other than perhaps spades.  My failure to control-bid says I have both other side aces, and the jump in spades shows a void."  I like this thinking, but will partner understand?  It reminds me of a time when I held all the aces and kings and tried opening 2 !C, and over the 2 !D waiting response, lept to 6 NT, hoping to convey that I didn't care about aces or kings, if you have queens, bid seven; with two queens and a jack, partner passed.  I fear that this is another time when the high-level inferences are over partner's head.

4 ♠   100   BWP 43%   BWS 71%  IAC 70%
Janice Seamon Molson points out that "Exclusing would be lovely, but five would take us into the stratosphere with no useful information.  Therefore, the nebulous cue-bid is always a favorite.  George Jacobs considers it to be the "Strongest possible move with the hope that partner can take control.  Will bid six after any forward-going move."  CCR3: "Ideal slam try."  Pepsi: "First-round controls in all suits warrant a slam-try."  Masse24: "Worth a slam move."  Jeff Rubens says "Don't know how we will make a high-level competitive decision later or reach seven clubs on our own, but I fear that if I bid anything else investigatory here, North will assume that I lack first-round spade control."  BluBayou wants the ace-ask to come from the right side:  "Still hoping to be showing 3 aces+ to pard's blackwood", but will partner take the 6 !H response (odd number of keycards plus a void in a suit above hearts) to show all three aces, or worry about missing two?  As Joey Silver puts it, "The problem will come later.  I will drive to at least six, but at this point I can see no way to reach to a grand with assurance."  Mats Nilsland: "Worth another bid, perhaps even five spades to show the void."  Dan Gerstman: "Might as well get some use for it before LHO save in four spades.  Not to hard to see slam opposite king-queens of our suits, and seven with a sixth club or the king of diamonds."  Jeff Meckstroth: "Give partner a chance but get out if he bids five hearts; otherwise, I will bid six."  David Berkowitz: "Start here; can we end in clubs?  I am not giving up on seven."  I just remember the law of unintended consequences and bridge; one time I had a partner that made a bid that caused me to try to place the contract, because he did not trust me, he took another bid - when we compared at the other table, he described my bid as "... then I lost control of the auction."

6 ♣   80   BWP 14%   BWS 1%  IAC No solvers
Then there are the blasters.  Philippe Cronier points out that "North was not obliged to bid four hearts with a poor hand and a lot of HCP in spades.  Slam could be much better in clubs.  For instance, opposite:  ♠ Kxx, Qxx, Kxx, ♣ KQxx, six hearts depends on the heart finesse, while six clubs is more or less on ice."  Barry Rigal: "Bid what you think you or your partner can make.  I've been wrong before."  Kit Woolsey says "I will drive to slam and don't see any intelligent approach to determine if partner has the perfect hand for a gran.  I'll suggest playing in clubs, which might be a trick better than hearts, particularly with no diamond lead."  Sami Kehela is "Not stopping short of slam.  (Picture 2=4=3=4 shape opposite.)  A grand slam is possible, but I can't find out everything."  Certainly, bidding clubs at the six-level shows the double fit and may be the best chance of getting to a grand, but I fear partner passing when it is wrong.

6    50   BWP 14%   BWS 11%  IAC 30%
The other blast is into hearts.  Danny Kleinman feels there are "Too many goodies to show individually, so I'll bid what I think I can make.  That will give the opponents the last guess, perhaps forestalling a profitable six-spade save, and perhaps facilitating a forcing pass and a possible grand slam if the opponents do bid six spades."  Carl Hudecek thinks "Six hearts (or six clubs) is less of an overbid than four spades at this point; with a spade void, four spades can only complicate things.  Partner would probably view it as showing the ace, and who knows where we would end up."  WackoJack argues "Since I have a void in spades, I imagine that partner likely has a balanced 12-14 with 3 hearts.  Say ♠Axxx, Qxx, KJxx, ♣ Kx where 6 !H looks good.  Shall I try 5 !H or 6 !H? OK lets go the whole hog and bid 6 !H."  Other than I think Jack may have his minor suits reversed, the reconstruction seems sound.  JCreech: "Partner opened and supported my six-suit at the four-level.  I have first-round control of all suits, and the opponents are showing a lot of length in my void."  Billy Eisenberg: "I'm too old to get involved in looking for seven."  Hoki: "science fails me"  Robert Wolff: "Fie on science.  Partner has somewhat limited his hand, so I give up on a grand."





Problem G  2 !D  (None)

Imps  Neither side vulnerable
You, South, hold:

♠ A    A J 8 6 4 3    9 4 3   ♣ A K Q

SOUTH   WEST   NORTH   EAST
   ——      ——      Pass      Pass
  1        Pass      2 ♣*      Pass
   ?         
*BWS: invitational-plus heart raise

What call do you make?

You open 1 !H in third seat and partner bids 2 !C promising an invitational (plus) heart raise.  You have 18 HCP, a six-card heart suit and losers only in the red suits.  If your partner's values are in the right locations, this could easily become a good slam.  How do you go about finding out about where partner's values lay?

2 NT   80   BWP 7%   BWS 2%  IAC No solvers
A few Panelist's bid 2 NT.  Janice Seamon Molson describes it as a "Forcing slam-try."  While Mats Nilsland is winging it a bit more: "We could have a slam, but how to find it?  Over four diamonds, I will bid a slam."  The idea has merit, but it is not a systemic response in BWS; in fact other than the simple rebid of hearts as a weak bid, there are no systemic agreements in BWS.

3    80   BWP 1 Panelist   BWS 1%  IAC No solvers
Bart Bramley tried jumping into diamonds:  "Best I can do.  I like this as a natural slam-try.  Here, it also has obfuscatory elements, since I would much prefer a black-suit lead.  I'll give up on slam over three hearts but probably ask for keys over a sign of life, though, that risks that a five-diamond reply will be doubled."  I truly dislike this bid.  In my own past, pretending to have length in a suit frequently leads to bad other choices.  I would much prefer a fake splinter into diamonds, than a fake jump shift.

3 ♣   90   BWP 25%   BWS 30%  IAC 40%
Many tried the slightly more natural 3 !C; half of the hand's HCP are in the suit, and while it is only three cards in length, the quality makes it feel almost like it has an extra card.  I think Jeff Rubens describes the best reason to make the bid: "To avoid encouragement from partner based on honors in my second suit or an isolated quack in another side suit."  Though most were looking for a cue-bid in diamonds.  WackoJack asks "How can I know if partner has useless high spades or very useful high diamonds? Best try 3♣ and see if partner bids 3.  If so then we are slamming."  Billy Eisenberg "Over three diamonds, I'll as for key cards."  Jeff Meckstroth describes the continuation: "Then three spades to clarify slam interest."  Dan Gerstman: "Over three diamonds, I'll keep trying; otherwise I'll settle for four hearts."  John Stewart: "See if partner can come in diamonds.  Not a fan of splintering with a stiff ace."  Michael Becker is more interested in finding shortness:  "Our best change of finding slam is when partner can splinter in diamonds.  I don't know how to reach six hearts when partner has king-fourth/ace-doubleton in the red suits, but bidding three clubs does not rule it out."  And I think CCR3 is only telling part of her reasoning: "Only because of the footnote. Showing shape. Fingers crossed."  I think that Pat's choice was also about showing where her values were, otherwise she might have bid 2 !D, her cheaper-to-bid three-card suit.  Nonetheless, BluBayou mentions what is in the back of everyone's mind:  "Wish we had discussed what new suit replies to old fashioned Drury were about" 

3 ♠   70   BWP 14%   BWS 16%  IAC 20%
Kit Woolsey describes 3 !S as "A model splinter.  If partner doesn't have much spade wastage, we want to be in slam, and he will cooperate with four diamonds."  I am more in tune with Masse24's thoughts "I never, ever splinter with a stiff ace. But I will here. I would like to bid a forcing 3 !H. And it should be forcing. But in a search through BWS I did not find that it was so this is my next best "slam move" option."  Similarly, Chris Willenken writes, "Not perfect, but the best I can do in BWS.  I will not make any further moves, as I need a great North hand for slam."  Joey Silver: "Not sure the reward is worth the risk of getting too high, as partner needs a perfect hand to make slam.  Should North bid four diamonds, I will bid four spades."  Barry Rigal: "Just worth it.  The right minimum hand:  ♠ xx    KQx    Axx   ♣ Jxxxx provides decent play for 13 tricks and a fun play in six hearts on a diamond lead."

2    100   BWP 36%   BWS 9%  IAC No solvers
The Panel plurality went with the cheapest positive response to the Drury inquiry.  Danny Kleinman "The artificial two clubs rather than two diamonds provides an extra step.  The Useless Space Principle says 'Fill it!'; my suggestion ... is that two diamonds asks for further shape information."  George Jacobs describes his continuations:  "Over two hearts, show controls on the way to game; over two spades, I'll bid four hearts; over three diamonds, I will control-bid.  I prefer to go slowly.  Assuming some of North's strength is in hearts, for slam I need a diamond control, and even the king may not be enough."  While David Berkowitz only mentions when he would bail: "Making it easy for partner to like diamonds.  If all I get is two hearts, slam is out."  Michael Lawrence: "In my methods, this asks partner to describe the quality of his hand, including whether he has three or four hearts."  Andrew Robson: "Can't cost.  I think we'll end up in four hearts, but three notrump and six hearts are possible."  Pepsi feels it is the "Best way to explore."  Phillip Alder: "Maybe a fake splinter in diamonds is best.  Who is West?"  Zia: "I know it's on my own, but three notrump may be best, and partner could have:  ♠ KQxx    Kxxx    x   ♣ xxxx."  Sami Kehela: "Why should Zia get all the ink?"

4 ♣   70   BWP  1 Panelist   BWS 0%  IAC No solvers
Of all the bids made by Panelists, 4 !C confuses me the most.  I agree with Richard Colker that it will "Focus partner on his red-suit honors rather than club weakness.  Some hands too weak for two clubs make six hearts cold, while better-looking hands give slam virtually no play.  Any other black-suit bid would be misleading."  But it wastes a lot of space and partner is bound to misconstrue the true shape of your hand.

2 ♠   0   BWP No Panelists   BWS 15%  IAC 20%
A couple of IAC solvers went this direction.  Personally, I bought into the idea, but on further reflection, I suspect it has the same problem as 4 !C - it misconstrues the true shape of your hand.  A reverse suggests length in spades that you simply do not have.  If Hoki is right, that it is "just a simple advance cue bid, leaving more room than 3S" then it is a great bid.  And JCreech has a point that "This may not initially be thought of as a cue-bid, but when I come back and cue the clubs, I think partner will catch on." However, as a manufactered reverse, you could be struggling to corral partner's flight to the stratosphere.  After all, no one has bid the suit, so partner may have been torn between bidding spades or raising hearts.

4    60   BWP 11%   BWS 20%  IAC 20%
The give-up action belongs to 4 !HCarl Hudecek thinks "With a dozen HCP missing.  I am not optimistic about slam.  In my younger days (65 years ago), probably I would have bid two diamonds."  Philippe Cronier believes "We can make a slam opposite a lot of specific North hands, but it is very difficult to know whether North has ace-low rather than ace-jack-low in diamonds.  An auction that revealed too much could tell the opponents what to lead, perhaps even how to beat four hearts with a diamond ruff."  Robert Wolff, however, seems to have rose-colored glasses: "Give up on science, although this is close to a fancy slam-try."  How Robert can view accepting a game-invitation as a slam-try is beyond me.


I ran out of space, so Part 3 continues in the next entry.

March MSC SUMMARY (Part 2)– Eric Kokish, Director

Problem D  1 NT (VeredK, VeeRee, CCR3, Hoki, BluBayou, YleeXotee, WackoJack, BabsG, JCreech, Masse24)

Imps  Both sides vulnerable
You, South, hold:

♠ K Q 10 7    A Q    4 3 2   ♣ A K 9 4

SOUTH   WEST   NORTH   EAST
  1 ♣       1         Pass      Pass

What call do you make?

I'm sorry, I only see two possible answers to this problem.  You have a balanced hand that is too large for opening 1 NT and not large enough for opening 2 NT, so you open your better minor, the opponents overcall 1 !H, and it is then passed back to you.  You have a potential double stopper in the opponent's suit, and it happens to be a doubleton (with at least three-card support in all the other suits).  Either you rebid 1 NT that describes your hand exactly, or you double, trying to get to something from the wrong side.  Is there any real reason to expect less than Masse24's "WTP? Unanimous by the panel?"

1 NT   100   BWP 89%   BWS 72%  IAC 100%
Not quite, Todd, but it is as close to unanimous as I have seen amongst the Panel members; however, IAC was unanimous.  Michael Lawrence sums up why make the bid: "Shows these values.  Rightsides notrump.  The main loss is that we can't defend against one heart doubled, but the South hand makes that unlikely."  WackoJack says "I just bid my hand."  Hoki "protecting the heart holding"  JCreech: "1 NT is right on points and shows the stopper, but the stopper is badly placed if West can find an entry to East early.  ... It certainly described my hand and protects the tenace."  BluBayou: "The heart AQ, along with the correct point-count cannot be denied.  If I reopened with a double and heard a spade response, i swear  I would convert to notrump even then."  CCR3: "another teaser. I don't think partner will have enough to use Stayman to find the spade contract."  Funny that Pat brings up spades in her comment because the number of spades held by partner is of utmost concern to many of the Panelists.  For example, Richard Colker "Partner's failure to double reduces the chance that we'd be better off in spades, and bidding spades here would suggest a more-shapely hand."  Robert Wolff: "Might as well gamble that we do not have a four-four spade fit.  I would like to become declarer."  John Stewart "As partner will have spades only if very weak, spades from his side may be no better than notrump from mine."  Philippe Cronier: "The best way to reach game.  Doubling could be embarrassing, for instance if partner bids two of a minor.  If North has four spades, he will have a weak hand."  While Bart Bramley focuses on the worst of times, as well as the best:  "Too bad if I'm down four when they run diamonds and lead a heart through.  On a better day partner will raise to three with:  ♠ Jxx    xxxx    Axxx   ♣ Qx, the lead will be a heart, and I will claim."

So what is the alternative enamored some of the Panel?  Spades.  Jeff Rubens says he "Can't expect North to bid the suit on three."  Danny Kleinman thinks "Responder's failure to bid one spade or to show four spades by doubling should not preclude playing in spades, but North may have passed from weakness.  One spade will rightside a spade contract, and not bidding notrump may fetchh a favorable heart lead."  While Sami Kehela tells us how close the decision is for him:  "Today.  Next time, I'll try one notrump."

Double   40   BWP No Panelists   BWS 19%  IAC No solvers
Neither the Panel nor IAC went with double, but nearly one in five Bridge World solvers did.  Why?  JCreech pointed out that "The hand has the right shape for the double, but if partner chooses diamonds, the support is very anemic.  I would be pleasantly surprised to hear a pass from partner if I double, but with me holding the AQ, I don't expect that to happen even with a stack."

What call do you make?

What a distributional monster, and of course, partner is bidding the other two suits; two excellent six-card suits and the diamond king as your singleton offsuit.  The primary question, of course, is what do you bid?  But there is an another question that could affect that choice - what does 4 !D mean?  Is it a cue-bid, a suit, or something else.  Not only that, but there is also a distracting debate regarding the phisophical style of opening two clubs vs. opening one in black suit with massive two-suiters.  These are all themes that reappear throughout the discussion.

4 ♠   70   BWP 25%   BWS 22%  IAC 50%
Michael Becker "At the start, I had a play for slam opposite a 4-3-3-3 yarborough.  The hand has become worse as the auction has progressed.  Partner has a lot of red cards.  There is no hope of identifying whether North has the diamond ace, and even if he has it, we may not have 12 tricks."  WackoJack makes the "Cheapest bid with likely misfit."  David Berkowitz thinks "Something fishy is going on; leave the next move to partner."  John Stewart: "Call me cowardly, but I have a peaceful uneasy feeling."  Michael Lawrence is "Going slow.  Facing a red five-five, slam won't be cold even if North has the ace of diamonds, and he has not yet shown it."  Jeff Rubens: "Once a chicken ..."  Carl Hudecek concludes that the contract "Should make opposite any 13 cards."  George Jacobs grouses that "Two-suited hands should not be opened two clubs.  Yes, occasionally we will play in one spade with six clubs cold, but there are 25 red cards missing.  To this point, South might have bid on five-five or six-five; let's show six spades.  Partner should be able to take it from here."  Echoing, JCreech says "I hate opening 2 !C with a two-suiter, but having done so, I will rebid my spades and hope partner can figure out what to do next."

5 ♣   70   BWP 11%   BWS 22%  IAC 20%
Danny Kleinman thinks "Until now, I've depicted only five spades and four clubs.  Five clubs comes closest to showing the freakish shape on what I fear is a serious misfit.  I object  to the problem, because (a) with equal length and strength in the blacks, I would bid clubs ahead of spades, and (b) because of the rigid BWS requirements for a natural positive two-heart response.  Given the straitjacket, I would have risked a one-club opening."  BluBayou feels that "Five Clubs may help partner bid slam holding the measly black suit help we need;  Four Spades will not.  That is enough for me to stop worrying about hitting a completely worthless dummy which would means the four level  is out last chance of a plus ( two black singletons might might bring home 5 clubs after all)"  Chris Willenken: "Four diamonds shows nothing in particular.  Partner could be offering a choice of games or temporizing with a hand too strng for any game bid.  Opposite 1=5=4=3, six clubs has decent play even if North has no useful high cards."  Hoki: "still possible to stop in game but not giving up on slam"  Nonetheless, I agree with Phillip Alder's play on The Charge of the Light Brigade "Into the Valley of Death rode the one bridge player, dragging his partner behind him."

6 ♣   100   BWP 43%   BWS 48%  IAC 30%
Andrew Robson "... would have opened one spade.  Are we super-confident partner is control-bidding and agreeing clubs  I'm not.  In a way, six clubs can't be right - either partner is showing the diamond ace, agreeing clubs, in which case we are making eight clubs, or partner has some weak red two-suiter and we make nothing."  Bart Bramley "Settling for game would be too conservative.  I don't see a way to investigate seven intelligently.  With:  ♠ x    Axxxx    Axxxx   ♣ Qx, North should raise."  YleeXotee is "glad to see others have made this choice too. now I don't think I'm going out on a limb"  Joey  Silver "... would have opened spade.  Two clubs tempts the villains to interfere and to prevent me from describing this hand fully.  Since partner has the diamond ace, the chance of a misfit is high, so I will go low and give up on looking for a grand."  CCR3 thinks the bid "Gives partner a choice. But what's 4D? I think it implies he prefers clubs. Slam is somewhere, but how high?"  Robert Wolff: "Unilateral, but this auction might demand that someone act that way.  Much more likely to make six than to be set, but to entertain a grand slam would be too much."  Masse24 "I would like to get fancy with a bold 5 !H, but I'm worried it could be misunderstood. I believe Kantar wrote about an exclusion bid in his partner's first suit but had never had the guts to try it. Me too."  Barry Rigal: "Auctions like this would go so much more smoothly if we could start two clubs - two hearts - two spades.  If four diamonds is a control-bid agreeing clubs, we will miss a grand slam; if it is natural we will go down at the six-level.  Not only can we not win them all, we can't win any of them."  Sami Kehela identifies the bid as "A shot, not in the dark - let's say in the penumbra."  Janice Seamon Molson is "Ever the optimist.  Anything could be right."  Billy Eisenberg considers the bid to be at "The right level to allow partner to make an intelligent choice."  While Jeff Meckstroth feels it is "A total guess.  Could be a misfit, but I have a shot at six clubs opposite as little as a stiff spade and two low clubs."  Zia is succinct with his "Too tuff."

4 NT   50   BWP 1 Panelist   BWS 1%  IAC No solvers
One Panelist pulled out the old, when in doubt, ask for aces.  Kit Woolsey "Partner's four-diamond call is not natural; one doesn't introduce the fourth suit at the four-level.  He is showing a good hand for clubs, but he need not hold the ace of diamonds.  If he has an ace, I'll take a shot at seven clubs, unless RHO doubles the five-diamond reply."

4    70   BWP 1 Panelist   BWS 1%  IAC No solvers
Dan Gerstman bids 4 !H because it "Gives North room to indicate which black suit he likes.  He's not bidding a queen-high suit, and four diamonds isn't an attempt to make diamonds trumps.  I will bid seven over five clubs.  Over four spades, I'll try five clubs."  I would be too afraid that the auction would end there in partner's suit.

7 ♣   60   BWP 14%   BWS 2%  IAC No solvers
While Mats Nilsland jams the hand into the stratosphere: "Hoping four diamonds was a control-bid."



This concludes Part 2.  I will return when I have time to brng the concluding Part 3.  Until then, please participate in next month's MSC problem set.

March MSC SUMMARY (Part 1)– Eric Kokish, Director

Problem A  Pass (Masse24, JCreech, BabsG, WackoJack, BluBayou, Hoki, VeeRee)

Matchpoints  East-West vulnerable
You, South, hold:

♠ Q J 9 8    J 9 4 2    K J 10 7   ♣ 7

SOUTH   WEST   NORTH   EAST
  ——      1          2 ♣        2 *
  Pass      Pass     Double   Pass
   ?         
*under invitational strength

What call do you make?

The vulnerability is tempting to pass the double; you have a stiff in partner's suit, and great cards in the opponent's suit.   However, you also have four-card support in both majors; if you bid, you risk choosing the wrong major.  Inaction or action, and if action, which action?  What can we expect opener's hand to look like?  Normally, I would expect at least four diamonds, and so the opponents would have an 8 or 9-card fit.  With partner overcalling in clubs, I think the chances of opener having 4=4 in the majors increase, as well as the chance for him to have a 3-card diamond suit.  Does that affect the calculus of our Panelists and solvers?

Pass   100   Bridge World Panelists (BWP) 68%   Bridge World solvers (BWS) 60%  Intermediate-Advanced CLub solvers (IAC) 70%
Inaction won out in terms of how the voting went;  nearly 70% of the Panel and better than 60% of the solvers went for the penalty.  Bart Bramley thinks "We're at least two-to-one to beat this, pretty good odds for a top-or-bottom decisison.  I have about three tricks (maybe four) and can expect at least that many from partner.  Matchpoints rewards high-volatility actions that are with the odds."  Richard Colker points out that "Pass has the highest upside and could be the winner even if a partscore makes (and we choose the right one), but it also comes with the biggest downside.  The choice here might depend heavily on our place in the even; after all, you've got to know when to hold 'em, know when to fold 'em."  JCreech:  "Getting the side right on this hand is a toss-up.  Both opponents have roughly equal length, and I might be in fat city or screwed, depending on lady luck."  A couple of players at least partly base their decision on rules.   Kit Woolsey used the LAW: "If partner were four-three in the majors, he would have started with a double; he is presumably 3=3=1=6.  With neither side having an eight-card fit, the trump total is 14, so bidding would be a trick-total violation, and the hand is very defensively oriented."  While Hoki says the hand "fulfills the rule of nine" (Mel Colchamiro).  Most of the solvers just cannot quite see the opponents making their bid:  WackoJack: "We need 6 tricks if I pass for penalties.  Give partner only 11 points say ♠Kxx, Axx x ♣Axxxxx and I can see 3 tricks in s (2+ruff) + 2 likely ♠+ 1 +1♣ and we get +200. I think we would have to be very unlucky for 2 to make."  BluBayou: "Why are they making, when partner says he has....Kxx, KQx, x, AQ?xxx  ??"  Masse24: "Partner is likely 34 or 43 in the majors. In which major does he have four? I choose to sidestep the problem and pass."  While the Panel focus more on the difference between 200 for the set compared to a partscore making:  Jeff Rubens: "Seems roughly as like a plus as two spades and pays more."  Philippe Cronier: "Probably the easiest way to get a good score.  Partner not a favorite to hold a four-card major."  Jeff Meckstroth: "Partner is probably something like 3=3=1=6; and the opponents are vulnerable, so a one-trick set looks tasty."  Sami Kehela: ""Take my chances here rather than struggle in a likely four-three fit."  Pepsi: "I don't want to punish my partner for an aggressive reopening, but 200 is so tempting."  Phillip Alder: "At the scoring and colors, I will gamble."  And Danny Kleinman seems to be playing a different game: "Pass. Go and collect 200 points.  Maybe more.  That'll teach our opponents not to open three-card diamond suits."

2 ♠   70   BWP 18%   BWS 13%  IAC No solvers
Taking a cue from Edgar Kaplan that takeout doubles are meant to be taken out and spades is the stronger major.  Robert Wolff intends to continue bidding if there is further competition:  "Then three hearts over most continuations.  Not strong enough for three diamonds, and pass is not my cup of tea."  Michael Lawrence is just trying to ensure a plus:  "Because the spades are stronger than the hearts; I expect a plus.  Passing works when North has two diamonds."  While others are looking forward to doubling diamonds at a higher level:  Andrew Robson: "I have only one sure defensive trick, so I bid the stronger major, better for a Moysian fit, and I may get to defend against three diamonds (which I will not double!)."  Chris Willenken: "Partner should reopen on almost every 3=3=1=6.  Not clear where we belong opposite a typical: ♠ Kxx    Kxx    x   ♣ AQ10xxx.  I hope to double three diamonds."

2    60   BWP 11%   BWS 12%  IAC No solvers
Others takeout the double by bidding up the line.  Dan Gerstman: "Takeout doubles are for takeout.  Give dummy four trumps and a trick (any hight card is a sinner with my hand) or five trumps and shortness, and there's a clear road to eight tricks in two diamonds.  Meanwhile, I an see scrambling eight tricks our way.  Easy to see 16 trumps and 16 tricks.  I bid two hearts in case partner has 4=2=1=6 and tries two spades."  Carl Hudecek: "Partner has a singleton or void in diamonds.  I won't pass when we have at least one, and perhaps two, four-four fits in the majors.  If the opponents compete further, I will have a less-risky penalty double."

3    20   BWP No Panelists   BWS 5%  IAC 1 solver
Although no Panelist took this route, if there is at least one 4=4 fit, 3 !D is the way to avoid guessing.  CCR3 "Really debated on this one. Hard to visualize winning 6 tricks leaving the double in. Yet 3d is a bit to high.  Finally 3d because my partner's cards are behind the opener."

2 NT   50   BWP 1 Panelist   BWS 10%  IAC 20%
Avoiding the guess, but still making certain that those diamond cards will be useful, YleeXotee "finally chickened out on the standing for the double."




Problem B  3 !D  (VeeRee, Hoki, BluBayou, WackoJack)

Matchpoints  Neither side vulnerable
You, South, hold:

♠ K 9 6 3 2    4    A Q 9 5 3   ♣ 9 2

SOUTH   WEST   NORTH   EAST
  Pass      Pass      Pass      1 ♣
  1 ♠      Double      2 ♣       2
   ?*         
*By agreement, 2 ♠ = weakest action.

What call do you make?

Both partner and I are passed hands.  I have a nice distributional hand, and partner has cue-bid suggesting support for my spades and good values for a passed hand.  A hint reminds us that 2 !S is the weakest action.  Should we regard our 5-5 nine-count as a minimum, or has it grown with probable support from partner and opener bidding our two short suits?

4 ♠   60   BWP 1 Panelists   BWS 2%  IAC No solvers
Blasting into game, Billy Eisenberg thinks "The more I look at the hand, the less three diamonds seems necessary."  And he could be right.  If partner has some fitting values in our two suits, game could come rolling home.  But perhaps we should be looking for a way to include partner in the decision.

2 ♠   60   BWP 7%   BWS 23%  IAC 30%
If 4 !S could be reasonable, then 2 !S may be a bit pusillanimous.  As the weakest action, it essentially says to partner to go away.  Pepsi has the best reason: "At matchpoints, I don't like to overbid; partner didn't bid two notrump, very likely has only three spades.  Game is possible, but a score on our side is always good."  Andrew Robson recognizes the hand's potential, "Clearly, the hand is strong enough to pass; but, with four decent hearts, partner might take a shot at defense and pass out two hearts.  If the opponents bid three hearts, I will make an action double."  But is unwilling to accept the risk of what he considers to be the best alternative, pass.  CCR3 thinks "Must bid something to show some value but not enough to bid 3d."

Pass   80   BWP 25%   BWS 5%  IAC 30%
Dan Gerstman describes pass as "The slightest possible encouragement.  Not three diamonds, as queen-third of spades, king of diamonds, and an ace would not be enough - it's too likely to get us overboard, the last thing you want to do at matchpoints."  Chris Willenken argues that "At matchpoints, partner would cue without game interest to help me double at the three-level, so I'm not willing to get past two spades.  We should reach game when it is right; we are both passed hands, so I must have bid distribution."  Masse24 thinks it is "Stronger than 2 !S, but not quite as pushy as 3 !D (which may be best as it is very informative). Tough problem." JCreech: "I like the weak call, but this is more flexible without bidding the diamonds immediately."  Michael Lawrence: "North rates to have a 10-count with three spades."  Zia: "Seems to show interest, which I have."  Danny Kleinman: "The spades are not quite strong enough for the weakest action, so I'll choose the weakest inaction."

3    100   BWP 64%   BWS 56%  IAC 40%
Although both members of the partnership are passed hands, game is possible with the right fit.  Phillip Alder points out that "Game is possible if we have a double fit.  Even though one doesn't usually push for thin games at matchpoints, this will help partner judge what to do should the opponents unexpectedly contest higher."  George Jacobs says "I solicit partner's worldly advice.  Many North hands make game very playable and some, such as: ♠ AQxx    Jxx    Kxx   ♣ xxx, make it a laydown."  Janice Seamon Molson "Could be right to bid four spades, but partner should get a vote at the four-level."  Blubayou says "As a "5th-seat overcall",  this is no way in the minimal range"  Hoki feels the bid is "limited by being a passed hand"  WackoJack: "Give partner ♠ Axx, 10xxx, Kxx, ♣QJx, then game in ♠ is likely.  So if our agreement is that 2♠ is the weakest action, then we must find an alternative. So lets try 3♦ and see if partner can help us there."  Bart Bramley: "At imps, I might bid game, since the hand could hardly be better; but at matchpoints, I'll pull in a motch.  Partner's red-suit holdings are key."  Carl Hudecek: "Trying to make up for the initial pass.  Two spades would be a gross underbid."  Kit Woolsey: "Partner won't play me for more than this.  I might as well show him where I live, in case the deal is a big double fit."  David Berkowitz: "Maybe partner can steer us in the right direction."  Mats Nilsland: "Not much extra but worth more than a pass or two spades."  Barry Rigal: "Possibly an overbid, but if I pass I might face an ugly problme the next time around."  Philippe Cronier: "We probably won't succeed in buying the contract at the two-level, so I bid my hand, letting North decide what to do later."  Robert Wolff: "Why not, since I passed originally?"  John Stewart: "Why not, when game is possible?  Minus one in three spades is a risk I shall run."  Jeff Meckstroth: "We certainly could have a game.  This describes the hand perfectly."



Problem C  3 !H  (WackoJack, BabsG, JCreech, Masse24, YleeXotee, Hoki, CCR3)

Imps  Neither side vulnerable
You, South, hold:

♠ K J 10 8 4 3    A 6 3    —   ♣ A J 7 6

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

The start of a basic 2/1 auction.  You have opened 1 !S and partner has responded 2 !H.  Your hand has a lot of possible stories to tell.  You could rebid the spades; they are certainly a suit that could play reasonably well opposite a singleton.  You could bid out your shape by rebidding clubs.  You also have three hearts, so you can raise partner's response.

2 ♠   90   BWP 36%   BWS 18%  IAC 1 solver
In some ways, Barry Rigal describes the best reason for going with spades:  "Raising hearts feels wrong when a six-one spade fit might play better than a five-three heart fit.  With so many messages to send, I should give partner enough rope to hang us both."  Similarly, Carl Hudecek "Leaves bidding room to get the most information out of partner."  Philippe Cronier says "I've so many things to tell that I prefer to listen to North's ambitions."  In short, Billy Eisenberg thinks it "Looks like the best start."  Several, like Michael Lawrence are concerned because "Other bids put hearts in front of spades.  I should have more room to show other things later."  Jeff Rubens: "Worth an effort to try to avoid a weak five-three heart fit.  If I bid enough hearts later, my major suits and overall high-level prospects will come into reasonable focus."  Danny Kleinman "As partner may have three spades and five hearts, spades may be our best strain, and I'll play there if partner raises."  Sami Kehela: "Can turn back to hearts if partner is unenthusiastic.  A decent six-two spade fit is preferable to a moderate five-three.  Forget clubs for now; can't do everything."  Dan Gerstman: "I can raise hearts later.  Maybe I'll even have a chance to show both minor controls.  But this is the one chance at showing six good spades."  John Stewart "Looking to have my cake and eat it too.  Maybe partner will do something convenient."

3 ♣   60   BWP 14%   BWS 15%  IAC 1 solver
Michael Becker has the most convincing argument for me to bid clubs next:  "I usually prefer to show a fit for partner a.s.a.p., but a raise would block me from describing my shape, and a splinter would suggest four trumps and take up too much space.  I will try to pattern out."  Bart Bramley points out that there are "Too many flaws for four diamonds.  In BWS two spades would be a nothing bid.  Clubs now and hearts next will get across most of the essential features, particularly three-card support and short diamonds."  BluBayou suspects a "Long, long auction just beginning?"  While Robert Wolff simply his next bid:  "The four hearts next, if able."

4    60   BWP 7%   BWS 14%  IAC 1 solver
As Joey Silver writes, "Despite only three-card support.  This has the virtue of simplicity."  While Mats Nilslander sounds like he has transferred captaincy to partner:  "Not inclined to go higher on my own."  What is wrong with the splinter?  Chris Willenken comes up with three without breathing hard (as he chooses bidding 3 !H):  "A four diamond splinter has too many flaws (only three trumps, diamond void, playability in other strains)." 

3    100   BWP 43%   BWS 51%  IAC 70%
As Pepsi puts it: "Old-fashioned bridge:  support your partner."  David Berkowitz continues: "Support with support.  Fabulous hand for hearts."  Kit Woolsey says "Establishing a playable trump fit quickly has the highest priority.  I don't have any problems splintering with three-card support when we have a definite eight-card fit, but here I don't want to shut out a three-spade call from partner."  Or as Hoki writes: "uninspired", or should we just admit, sometimes you just need to revert to the basics.  WackoJack, ticks through the ways that he could raise hearts: "I must show support immediately. So a forcing 3♥? 4♦ splinter?  Or even 5♦ splinter? I think the most economical bid allowing partner to express her hand more."  Andrew Robson "If I'm in doubt, I support.  The ten of spades is steering me toward two spades, but why mastermind so early in the auction."  Jeff Meckstroth: "Best to show the heart fit first."  Richard Colker: "Raise with support.  There will be room to find spades..."  Masse24 "Support with support. Making the best use of space, if I could rebid 2 !S and promise six I would. But that is not BWS. If I did rebid 2 !S then support hearts later, it might be construed as Hx."  JCreech: "Partner should have five, so I may as well raise and let him know of the fit.  Tempting as it may be, I don't want to reverse into clubs for a delayed support (implying diamond shortness)."  CCR3: "Hope to set up spades, the longer suit for pitches. Plenty of entries in dummy."  George Jacobs: "I prefer four trumps to splinter.  I will respect a signoff."


This concludes the first segment.  More will come as time permits.  Next month's contest has already started, please consider joining in and let us know how you would bid these problem hands.

Darn it! Why didn't I pass on Problem A?!

And why didn't I stick with my initial answers for C, G and H.  Because I got sucked into believing in, or at least accepting of, a different answer. I got lucky that I really did not get the 400 I deserved for making so many switches, but the zero for an answer I would have never thought of on my own is a reason to stick more to my original choices,  or at least only switch when I was initially tempted (as I was on A).

Several changes this month.  I am risking a 400 based on all these changes.

SOLUTIONS FOR:
James Creech

FREDERICKSBURG VA 22407-9355
U.S.A.

PROBLEM A: Pass  Getting the side on this hand is a toss-up.  Both opponents have roughly equal length, and I might be in fat city or screwed, depending on lady luck.
PROBLEM B: Pass  Todd got me rethinking on this one.  I like the weak call, but this is more flexible without bidding the diamonds immediately.
PROBLEM C: 3 Hearts
PROBLEM D: 1 Notrump  I almost committed to this initially.  It certainly described my hand and protects the tenace.
PROBLEM E: 4 Spades
PROBLEM F: 6 Hearts
PROBLEM G: 2 Spades  Hoki is right, it is a cheaper bid.  This may not initially be thought of as a cue-bid, but when I come back and cue the clubs, I think partner will catch on.
PROBLEM H: Spade 2  I still like my original idea, but chickened out.  No good reason other than to follow the crowd.

Has anyone ever made an Exclusion KCB bid in partner's suit?

A belated Happy New Year! to everyone.  I'll just throw in my sixpennyworth on this one.  Yes, twice, both when I had a 2 !C opener.  After 2 !D relay and my rebid, the suit that partner bid might be pretty weak.  I remember one auction: 2 !C - 2 !D - 2 !S - 3 !D - 3 !S - 4 !S -5 !D (Exclusion). 

I can't remember the other auction, but I went off in the ensuing slam.
Hey Dick,

Good to see you posting anything on this forum again.  Please feel free to add your sixpennyworth to the MSC answers.  I've missed your perspective, and would love to see it represented again.

For problem B:  we bid  3 !D    with 10x,  10 8 x x, QTxx, Qxx because that is less likely to catch a RAISE, than   3 !H is.   There is some kind of chance that Mr. Spades may rebid hearts himself  whereupon we can DROP HIM :D   ( I really am not enthused with this hand, ok?).  One quoted panelist pointed out that partner might pull     3 !D  to a 6-card spade suit,  but leave us in a lousy 3 !H  situation...  All the better for 3 !D  if true.

I am truly shocked, Jock, (with tongue firmly in cheek) I always thought of you as being old-school in choosing length over strength in response to a double.  It is clear from a direct comparison of the heart and diamond suits (as presented by you), that the heart suit is longer and should have been your pick (if not the panel's):

10 8 x x  (hearts)
QTxx       (diamonds).

Congrats on having a better reason for selecting diamonds than any member of the Panel.  In the end, I still think the most likely distribution will be 5=4=3=1 (with the hearts and diamonds equally likely to be either the 4 or 3).  With this shape, I don't see North pulling to spades holding three of the chosen suit; there will be hope that you picked your 5-bagger.  With a 6=3=3=1, including a good 6-bagger, I could see North pulling to spades believing that the risk of a poorish 4-3 too great to leave the contract there.  However, if there is an inclination to pull, I can see the inclination being acted upon more often when the chosen suit is diamonds, than if the chosen suit is hearts.  Spades and the red suit may play equally well, but hearts pays the same as spades; the lower payoff of diamonds increases the greed of being in a major.

Matchpoints is a nasty version of the game.

February MSC SUMMARY (Part 3)– Jeff Rubens, Director


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

Imps  East-West vulnerable
You, South, hold:

♠ A J 6 3    8 7 5    Q 2   ♣ A J 6 5

SOUTH   WEST   NORTH   EAST
  ——      ——        1         1
 Double    2         3        Pass
   ?         
What call do you make?

Like the last problem, the good news is that you have an opening hand opposite a partner that opened, this time the bad news is that both opponents are interfering with your auction.  Your first call was easy, a negative double that described your shape nearly perfectly (biddable length in both black suits with values to be at the two-level), but partner has stuck with his diamonds and you do not have a stop in the opponents' suit; how best to proceed from here?

3    100   BWP 48%   BWS 72%  IAC 75%
Boye Brogeland bids 3 !H:  "Forcing and asking for a stopper.  Easiest problem in this set."  JCreech says "I am wanting to avoid 3 NT without a stopper or 5 !D without heart shortness"  Jerry Stamatov thinks it "The only possible bid. ... At imps, we must reach game.  I will pass three notrump or bid five diamonds."  Eric Stoltz "I will support diamonds unless partner bids three notrump.  If North is short in hearts (certainly possible, as the opponents are bidding vulnerable), we may be on for a high diamond contract."  Masse24: "WTP? I’ve shown my spades, now it’s time to show my values."  YleeXotee is "asking for a stopper."  Bart Bramley: "Some game should be decent.  Unclear whether three hearts implies help in hearts; I think not, but the South hand may have biased me."  The remaining comments were variations of Al Roth's "What's the problem?"  Zia: "Must be a safe start."  Fleisher and Friesner: "Self-explanatory."  Phillip Alder: "Somewhat automatic."  Robert Wolff and Billy Eisenberg: "Stands out."  Ralph Katz: "Makes life easier."

3 ♠   80   BWP 30%   BWS 5%  UAC 25%
There was strong support for 3 !S from both the Panel and IAC, but what should it mean?  Frank Merblum "Shows game or slam interest in diamonds or doubt about notrump."  Sami Kehela has one answer:  "Giving up on an unlikely three notrump.  This should clearly be understood as an advance control-bid for diamonds."  Carl Hudecek has a somewhat different concept:  "The double denied five spades, so this suggests a good hand with four spades and probably no heart stopper."  WackoJack largely agrees with Carl:  "With a minimum unbalanced 1 opener, partner would pass.  So 3 shows extras.  But is it forcing?  I am not promising any more than a 4 card suit with 5HCP.  So it is not forcing.  I have about 2 tricks more than promised so I want to be in game and slam is not out of the question.  What would 3 mean?  Normally when there is still an unbid suit (clubs) a bid of the opponents’ suit would be telling partner 'I have a stop so you can bid 3N in safety if you have ♣s stopped' However, there is something wrong with this generalisation when you can only bid the 4th suit above the level of 3NT.  Therefore 3 cannot be telling partner of a stop.  It must be a 'tell me more' asking bid.  Nevertheless, I am hesitant to do so because say partner has something like ♠ xx, Ax, AKJxxx,  ♣ KQx.  Then he will bid 3NTand we have missed 6.  I am too good to bid 3.  I will keep things going by bidding 3♠ which will be showing a control and not extra length and will not promise a stop."  While BluBayou may be incorporating one or both ideas, but is not wholly clear:  "Tooo SIMPLE!   In no style I know of, or ever want to know of, does '1 !D  (1 !H ) double 2 !H ; 3 !D  (pass) THREE SPADES'   show five+ spades!  there is no need at all  for some mystery cue-bid if you agree with this.   This is a one-answer problem  or Bob's my uncle --  with the distant other answer being to drop pard in three diamonds --  scoring a minus 50."  And David Berkowitz seems to view it as a form of :mark-time" bid as he writes:  "Do not force North to bid three notrump.  I need him to want to bid it.  (What I really want to hear is four hearts; but I usually don't get the lucky.)"

4    50   BWP 11%   BWS 10%  IAC No solvers
Some give up on notrump, but Eric Kokish seems to have forgotten the forcing/non-forcing discussions of the past two months:  "This is a great hand for diamonds, and a forcing four diamonds is the clearest message-carrier."  4 !D is not forcing in BWS.  Kit Woolsey explicitly is "Willing to give up on three notrump.  Queen-low is likely to solidify partner's suit, and we might belong in four, five or six."  But implicitly, is also willing to give up on game without partner pushing onward.

5    40   BWP 7%   BWS 8%  IAC No solvers
To force to game in diamonds is easy.  Bid it as Danny Kleinman does:  "Why hand the ball off when I see a big hold in front of me?  How else to show three workers with two helpers?  I thought of jumping to four hearts, but partnr may be unable to tell a Bluhmer from a splinter."




Problem G  Double  (Masse24, JCreech, BabsG, BluBayou, YleeXotee, CCR3, VeredK)

Imps  North-South vulnerable
You, South, hold:

♠ A K J 6    A K J 9 5 3    —   ♣ J 6 5

SOUTH   WEST   NORTH   EAST
  ——       1        Pass      Pass

*BWS: 2 = majors

What call do you make?

A balancing seat problem, where you have 17 HCPs, a very nice six-bagger in hearts, and potential in both black suits as well.

Double   100   BWP 56%   BWS 61%  IAC 88%
A majority of the Panel clearly chooses to double, with an even greater percentage of solvers accompanying the parade.  The primary difference is that the Panel is understandably concerned that partner may pass.  Joey Silver thinks "Two hearts would risk burying spades, two diamonds would misdescribe the majors, and double riskes a pass from partner.  There are three places to play, so I'll chance a double as the least of evils."  Jill Meyers says "Double and pray that partner does not pass.  I stongly hate doubling with a void, but the hand is too strong for two hearts."  Danny Kleinman feels "Game is not sure, so I'll risk partner's pass.  Second choice: four hearts, which may be beatable but succeed when the defenders need to play in the dark."  Boye Brogeland: "I don't want to commit to hearts, and showing  five-five majors could land us in the wrong spot.  Partner might pass the double when we have a better-scoring contract ourselves, but on a good day he will be stacked in diamonds, and we might not have a game."  John Swanson believes that "At this vulnerability, partner will avoid a speculative pass."  Billy Eisenberg thinks "Too much hand for one heart."  JCreech: "I have enough strength to double and bid my hearts, and who knows, partner may show up with spades."  Carl Hudecek: "Strong enough to double and then bid hearts."  YleeXotee is "bidding hearts later. but could be convinced of a spade fit."  Masse24 avoids one alternative: "Don’t like 6-4 Michaels."  John Hurd thinks the problem "Seems routine."  While BluBayou elaborates:  "there is absolutely no need to look beyond the one obvious answer--in this case 'double'.   I can't believe they didn't present a second round of bidding and ask us what to call after some 7-bid auction."

2    80   BWP 33%   BWS 20%  IAC No solvers
For some, the Michaels cue-bid is easy.  Sami Kehela: "I have the majors."  If you choose this direction, you really need to have a plan.  Kit Woolsey thinks there is "Too much potential to risk partner's passing a double.  When I bid four hearts over two spades, partner will take into account that I might have this shape."  Jerry Stamotov believes "Double is possible, but I hate to do that with a long suit and void.  Partner will expect five-five, but I plan to bid hearts in any continuation."  Robert Wolff says "Easy for now, and three hearts over a two-spade advance would be 'in the cards.'"  Bart Bramley: "The three hearts over two spades.  This comes closest to describing the hand, without risking defending against one diamond doubled."  And prescient Zia recounts his prior experience:  "Years ago, I had a similar hand, bid two diamonds, then four hearts, and hoped."

1    30   BWP 7%   BWS 7%  IAC1 solver
Tackling this hand one element at a time, Ralph Katz makes "An underbid, but double would be trying to torture partner, and all other bids have bigger issues than one heart."  Similarly, WackoJack writes "I don’t think there is much risk in 1 being passed out when a game is on our way.  1. The odds are that West will help us by rebidding 2 and now I show my good 4 card spade suit"



Problem H  !C J  (None)

Imps  Both sides vulnerable
You, South, hold:

♠ 10 8 4 2    A 10 8 3    10 4   ♣ J 9 2

What is your opening lead?

You are defending 3 NT following an auction where the only suit that was raised was introduced as the fourth suit.  It is an ugly auction, and you hold an ugly hand to lead from.  I think the characterization of the opening lead is your side's first mistake is very fitting.  So what will be your first mistake? 

The moderator, Jeff Rubens, wrote "The panel gave at least three votes to each suit, an indication that the uncertainty level is on the high side, or maybe a little higher."
 
3   60   BWP 11%   BWS 31%  IAC 50%
The least popular suit among the Panelist only had one comment, and it was not much better than Todd's infamous "I hate lead problems."  And that was Phillip Alder's "I hate all 13 cards."  There was more being said by the IAC solvers.  JCreech is "Not sure what to expect for dummy's raise of hearts after bidding both minors.  I don't expect much in declarer's hand for the fourth-suit forcing.  My suspicion is that either the hearts are 4=3=3=3 or that partner and I have the 4=4 fit."  While YleeXotee is "... going to test that heart stopper"

10   80   BWP 22%   BWS 22%  IAC 50%
The diamond leaders are hoping to hit partner's long suit.  Jerry Stamatov thinks "Dummy is very likely 1=4=4=4, and declarer is prepared for a spade lead.  Partner is marked with at least four diamonds, and we can hope for five."  Eric Stoltz feels "Any lead could be fatal.  Dummy will be short in spades, so I don't want to lead into declarer's tenaces with my weak holding. ... A diamond might be bad, but it seems most likely to be declarer's shortest suit."  BluBayou: "Dummy can be counted on to have a 3-suter as bid.  Declarer ,however seems to have used artificial  4SF for his 2 Heart rebid.   ..Now, I have put off  for 3 weeks deciding WHICH little heart to lead, but suddenly see that hearts is not the suit to attack!   Wouldn't East, with a small singleton heart bid 3 spades to "command"  west take the notrump?  So his 3NT will deliver some heart helper.  yukk.  it comes down to a guess between the doubleton ten  and jack-third , just like last month."  John Swanson: "First the opponents raise my hopes that they will declare in a poorly-splitting suit, then they put me on lead with a guess of which minor to lead.  Today, it's a diamond."  Kit Woolsey points out that "Since we aren't running any suit, I want to make a safe lead.  This is the only suit I can pick and be pretty sure I won't be blowing a trick."  WackoJack asks "What does a raise of the 4th suit show here?  East cannot have a 4 card suit here unless 5413 distribution.  Could West be showing a 1-3-5-4 distribution with no stop?  Perhaps.    Maybe the 'beginner’s' lead of the 10 is best finding partner with a 5 card suit and more importantly not giving a trick."  Boye Brogeland: "I see no tempting lead and hope not to blow anything in diamonds, after which declarer will need to struggle for nine tricks."

♠ 2   80   BWP 19%   BWS 15%  IAC No solvers
The IAC solvers did not find the spade lead enticing.  Panelists, though, seemed to find the expected singleton or void in dummy compelling.  Joey Silver argues that "West has a singleton spade, while East's two hearts did not guarantee either a real heart suit or a five-card spade suit.  Leading a spade looks to be both safe and attacking."  Fleisher and Friesner thinks the lead "Seems safer and more likely to set up a few tricks than a club. ... The fact that opener is marked with a singleton or void in spades (whereas responder's club holding is unknown) makes a spade lead preferable." Danny Kleinman believes the lead "Not good, but everything else looks worse.  I may not be happy if the missing spades are one-three-five around the table and partner has king-third, but even then, it won't hurt if dummy's singleton is any of the three other honors."  Eric Kokish is simply biding his time:  "East surely has decent spades facing known shortage, and we may do best by staying off the other suits until we know more.  We might eventually build a slow spade trick of two while declarer guesses his way through a losing general plan."

♠ 4   70   BWP 7%   BWS 1%  IAC No solvers
The other small spade was penalized for not following partnership agreements while not providing a reason for the false card.  Carl Hudecek simply wants to "Attack with a suit where our side has length, probably eight-plus cards."  While Robert Wolff would have done slightly better by going with his second choice:  "Or the spade deuce."

♣ J   100   BWP 33%   BWS 7%  IAC No solvers
If you are awaiting the wisdom of the Panel for why a club, and more specifically, why a jack, you will be more disappointed with the latter answer than the former.  The only Panelist to address the second question was Bart Bramley, who focus first on why not one of the other suits: "Not a spade as declarer rates to have at least five.  Not a heart from a broken holding through dummy's four-card length.  Not a diamond, which may be one declarer's primary trick sources.  In clubs, leading the jack will gain more often than lose compared to the deuce, particularly when partner has four ..."  Everyone else seems to be hoping to find partner.  Kamil and Sherman, for example, are "Hoping either to hit pay dirt or just to survive.  Won't be shocked to end up with egg on our faces."  Oren Kriegel is "Trying to hit partner's suit.  I have more help in clubs than in diamonds, and West may have fewer clubs."  Ralph Katz is "Dreaming of catching partner with the ace or king-ten, plus a good spot card."  Frank Merblum simply is "Hoping that partner has four useful cards." 



This concludes the recap and summary.  I hope you found it useful, interesting, or at least entertaining.  The new MSC contest is going on now; if you have not participated in the past, please dip your toe in the water.  If you have stepped to the side recently, please try to find the time to rejoin the discussion; we miss you.

What call do you make?

Partner has made a nebulous cue-bid, and now you have to decide how to respond.  I call it nebulous because you really cannot tell whether the bid is an ask or a tell.  Is it asking for a spade stopper, as the IAC solvers all believe?  Or is it a raise of your diamonds, a suit you freely bid at the three-level, and, if so, what is your next move?

4    60   BWP 11%   BWS 9%  IAC No solvers
Carl Hudecek, makes his own cue-bid because "Three spades was a control-bid, showing a fit in diamonds, I assume that partner is void of spades, but the spade ace may not be useless."

3 NT   100   BWP 30%   BWS 46%  IAC 100%
John Hurd says "Seems routine."  No one else seems to agree.  David Berkowitz, for example, points out, "Game first.  Partner's call is not yet a slam-try, it is firstly a punt, e.g.:  ♠ xxx    Qxx    Axx   ♣ AKxx.  I must admit to my spade stop.  while I do have extra values, the hand has no direction."  Similarly, Bart Bramley says "Three spades was punt until proven otherwise.  No need to stretch for what might be a thin slam at matchpoints when three notrump will be popular, and I can gain point in the play.  If slam is good, partner may be able to continue."  BluBayou also echos: "Do we all realize that pard's 3 Spades will usually be a waffle?  What can an ordinary opening had lacking a spade card AND a heart suit do after all??  It's too early to get rowdy yet--just do what Hamman says for now"  Masse24: "I worry this is not enough. But let’s see where partner is going with his cuebid. If he passes, we are where we belong."  WackoJack asks "What is partner telling me? Most likely a balanced 12-14 with no spade stop. If so  with my semi balanced hand and the A♠ I must bid 3NT.  Could partner have an unbalanced hand with support say ♠ x, Qxxx, AQx, ♣ AJ10xx when we would want to be in 6?  Or even the same with ♣AKxxx when 7 is a laydown?  Then partner should take out my 3NT into 4 to tell me this news."  YleeXotee: "i think this is going low, but I can't quite think of how to proceed."  Nonetheless, there were several that seemed interested in bidding 4 NT if they could be certain of the bid's meaning, or the hand met slightly different criteria.  Boye Brogeland says "The hand is work 3.5 notrump.  I believe that the field would bid three notrump in this situation, so I copy that and hope that partner has a balance hand with 12-14 HCP rather than a good hand with clubs."  JCreech: "The question is whether I am being a wimp by not jumping to 4 NT (hopefully quantitative under the circumstances)."  Fleisher and Friesner: "If we were sure that four notrump would be interpreted as natural, we would bid it - if partner has extras and combined we have a source of tricks in diamonds and/or clubs, slam is likely to be a favorite.  However, this sort of bid is easier to handle in the postmortem than at the table."  Jill Meyers feels the hand has "The values for four notrump but no running suit."  While Oren Kriegel has his own hesitancies:  "Four notrump (or some other forward-going bid) might work out better, but the hand is a bit too light for four notrump, and at matchpoints I don't want to bid a suit."

4 NT   90   BWP 20%   BWS 16%  IAC No solvers
Nonetheless, there was a strong contingent, more certain of the bid's meaning, willing to jump to 4 NT.  Frank Merblum, for example, thinks "Partner either has a weak notrump with no spade stopper or an excellent fit for diamonds.  Four notrump is a natual slam-try with no clear direction."  Eric Kokish says "Three spades is not yet known to represent a powerful hand; rather, it is a grope, perhaps with 3=3=5=2 or a balanced hand with three-card diamond support and modest values lacking a spade guard.  Three notrump may be the last plus, so there is a noose (not a moose) element in bidding anything else.  However, if North has long clubs or diamond support, these cards are good for slam, and the main downside to four notrump is that maybe we can't make it (could be down a lot, in fact)."  Ira Chorush: "Partner's bid is ambiguous in that it tells us nothing about his hand.  It would be mandatory with many weak notrumps, as well as with some very-distributional hands with good clubs and diamonds.  Therefore, we will do best by describing your hand; four notrump shows slam-onvitational values in a balanced hand with a spade stopper."  Joey Silver feels that "With no trump suit agreed, this is natural."  Jerry Stamatov is "Trying to show a little extra, not ideal with ace-low-low of spades."  Phillip Alder: "A tad too much to settle for three notrump."  Kamil and Sherman: "We can't call it a day at three notrump.  This fits best, even if imperfectly.  We'd rather hold king-jack-low of spades, but this is what were dealt."  And Zia asks, "Who knows?  But it's never exactly nine."

4 ♠   70   BWP 15%   BWS 24%  IAC No solvers
Some are not content with simply trying to interpret partner's cue-bid, they see the cue, and raise it one.  Sami Kehela goes with the simple interpretation:  "Partner is probably angling for three notrump, but I have too many values to comply."  Eric Stoltz "Not certain what partner is selling, but I am buying.  Three notrump would be too unilateral and might wrong side the contract, especially as East bid red against white.  I have a potentially-great hand opposite a real club suit and/or a diamond fit."  Robert Wolff feels it is "A fairly easy choice, at least for now.  I'm almost sure we will wind up in at least a small slam."  Danny Kleinman finds the choice "Close between this and pick-a-slam five notrump with the intention of raising partner's reply one level.  Five notrump could get me in trouble if partner replied at the seven-level and I tried to raise."

4 ♣   70   BWP 11%   BWS 2%  IAC No solvers
The bid I understand least is returning to partner's first-bid suit on Qx when partner's cue-bid is still unclear.  Kit Woolsey wants to "... see if partner has diamond support.  If not, he pretty much must have long clubs, since with four hearts he would have bid three hearts.  This is a huge hand, as North apparently has nothing wasted in spades."  Ralph Katz the cue-bid "... as showing a strong hand, not necessarily a slam-level control.  If partner bids four diamonds, I will face another decision."  John Swanson thinks "The club queen has become such an important card that, along with the controls, there is enough to force to slam.  Four club has the advantage of giving partner options at the four-level, which will provide an opportunity to determine strain and level."



Problem D  2 !H (VeredK, BluBayou, JCreech)

Matchpoints  Both sides vulnerable
You, South, hold:

What call do you make?

An auction that occurs all too frequently.  Partner opens a major, you bid a forcing NT, and partner rebids a minor.  You hold two in partner's major, four in partner's minor, and five in your own major suit.  Three potential places to play, with strengths and weaknesses associated with each.

2    100   BWP 56%   BWS 25%  IAC 37%
The strength to bidding 2 !H is that your hand will be worth more tricks than as dummy to one of partner's suits, the weakness is that partner will be expecting six and there is a possibility that diamonds will be a safer contract.  JCreech is "Torn between three weak calls.  The 1 NT has already given partner the warning to tread carefully.  I am going with hearts so my hand will be worth some tricks.  I am hopeful that partner has three having bypassed clubs (though that might indicate real diamonds and a stiff heart)."  While BluBayou says "I have never shown a 5-card red suit after this auction, but.....Jim put a bee in my bonnet:: in hearts, I AM worth some tricks, more than usual COMPARED TO WHAT a crappy dummy this is for spades. we will not speak  of  dropping pard in 2 !D ,  ok?  ...This TRULY  a "misery preference"  to 2 spades--worse even than  most 6-to-9 with a doubleton trump   compared to the alternative of 2 !HJohn Swanson thinks the bid "Offers a bit of flexibility, and the suit is worthy enough."  Carl Hudecek seems to just like his hearts:  "I dislike bypassing a good heart suit (by giving partner a spade preference on two low), and I dislike bypassing such good hearts by raising diamonds."  As does Frank Merblum: "Tough hand at matchpoints, but I like the quality of the heart suit."  Jerry Stamatov: "Although partner will expect six hearts, these five are good enough.  On a good day, I will hit partner with 5=3=3=2.  And if North has a singleton heart, he can get back to spades."  Several suggest that they would not bid hearts except holding a specific card.  Billy Eisenberg: "Thanks for the heart ten."  Phillip Alder: "An earlier experience with this hand-type involved bidding two spades with a poor outcome.  That eight of hearts was just too tempting."  Ira Chorush: "Without the eight of hearts, I would bid two spades."  Bart Bramley feels 2 !H "Should be best when partner has two or more.  Might survive when he has fewer, especially as then North might not pass.  I'm looking at the strong heart interiors, whereas partner's interiors are unknown."  And Sami Kehela points to system uncertainties: "Why not?  In BWS, the partnership could have eight hearts and only seven diamonds."

Pass   80   BWP 26%   BWS 25%  IAC 1 solver
The strength to passing is that you know you are in at least a seven-card fit, but could be more, spades is pretty much limited to seven, while the combined heart holding could be anywhere from 5 to 8.  For example, Oren Kriegel thinks "Game chances aren't great, and very likely we have an eight-card diamond fit.  At matchpoints, I expect that partner would have passed with most 5=3=3=2 hands, even some with which he would have accepted a game-invitation."  Eric Stoltz feels "The odds are high that two diamonds represents a four-plus-card suit.  This is a minimum hand, so it would be too risky to try two hearts.  Pass yields the best chance for a plus."  John Hurd points out "The more aggressive North's opening style, the more the pass stands out."  Kit Woolsey argues that "Plus 110 for nine tricks in diamonds ties plus 110 for eight tricks in a major, and I doubt that we have plus 140 available.  Bidding either major could result in a terrible contract."  YleeXotee: "i think this is going low, but I can't quite think of how to proceed."  Robert Wolff says "Passing is relatively safe, and a passer can expect a plus score; flying to two hearts, which is likely to be passed if North has a singleton heart, will often lead to a minus score ... everything considered, it has a lower matchpoint expectation than pass."  Boye Brogeland: "We have found a fit and rate to go plus.  Bidding a major may be a way to go minus."

2 ♠   50   BWP 15%   BWS 42%  IAC 50%
Going for the sure 7-card fit in a major, some  are concerned about partner still having a strong hand.  For example, WackoJack "Not playing Gazzilli partner could have 18-19.  So I must not pass.   I think a preference bid of 2♠ is about right. ... In my book 2 !S will deny a 3 card suit otherwise I would raise immediately.  I pity those poor souls who have to respond 1NT when they have a weak 3 card raise."  David Berkowitz also feels he "Must keep the bidding going in case partner has something."  Most are just worried about getting out in the best contract.  Masse24 is "Really torn between the 'book' 2 !S and a heart suit just good enough for consideration. But I’ll stick with the “known” 5-2 fit rather than the hoped for 5-3."  Jill Meyers "Partner did not promise four diamonds, so I choose a known seven-card major-suit fit where I have a ruffing value."  Kamil and Sherman "Not pass for a variety of reasons.  Two hearts would land us in an unfortunate contract far too often, thus the unhappy preference."  And finally Zia weighs in: "Am I really this sick?  I guess so."



Problem E  2 NT  (WackoJack)

Imps  North-South vulnerable
You, South, hold:

♠ J 6    K 9 4 2    A K Q 3   ♣ 10 6 4

SOUTH   WEST   NORTH   EAST
  ——      ——      1 ♠         Pass
  2       Pass       2 ♠*       Pass
   ?         
*BWS: need not be six-plus-card suit

What call do you make?

The good news is that you have an opening hand and partner opens first.  The bad news is that you made your game-forcing response in a four card suit and you only have two in partner's suit.  It looks like you are headed for a notrump contract, but what will be your route.

Oren Kriegel: "According to a secondhand account, Kevin Bathurst has described two-over-one auctions this way:  Opener rebids two of his major, responder rebids two notrump, and then they start to describe their hands.  That seems to be the right approach here.  I won't commit the partnership to spades or worry too much about club weakness.  There may be time to get out of notrump, and heart weakness might have been why partner did not rebid two notrump."  David Berkowitz continues with: "A classic mark-time bid.  It gives partner the most space to explore."  Though I think WackoJack may have the best simple description of the sequence:  "I have a balanced 13.  So I will bid a forcing 2NT."  And we end up in an auction that John Hurd sums up:  "This is terrific.  We are at two spades and neither knows how many cards partner has in any suit."  Or as Danny Kleinman rephrases: "Routine.  Thank heaven for game-forcing two-over-one response that unburden us of premature strain decisions with game-going hands."  2 NT may be the Panel's choice, but one thing is clear - no one really likes the bid, but no one really likes the alternatives.  Jill Meyers says "There is no great bid available.  Partner can bid three spades to suggest making that suit trump."  Kit Woolsey feels it "Gives partner the most room and is descriptive.  If we have a club weakness, we might be able to sort it out in time."  Ira Chorush points out that a "Lack of a club stopper and possible wrong siding are defects, but bidding notrump now may allow an escape to spades later if partner does anything but bid three notrump.  If North bids three notrump, the opponents may lead the wrong suit."  Joey Silver: "Most descriptive, albeit slightly flawed in the club department."  Eric Kokish: "Pretty awful but more flexible than three spades or an ultra-ugly three hearts.  I hope that North will mention a different strain if three notrump is not obvious.  Of course, playing from the wrong side is no joke."  Billy Eisenberg reiterates the basic position:  "Not without some concern."  While Kamil and Sherman summarize the position of the adherants:  "As close as we get to, 'What's the problem?'  No second choice."

Although the Panel is mostly in lockstep with the 2 NT rebid, the solvers are slightly more in favor of showing their heart values.  This has the advantage of right-siding the contract more often, but is suggestive of a more distributional hand, eats up bidding space, and may give the defense an important clue as to how to proceed.  Masse24 describes the bid as "Keeping 3NT alive and highlighting the club problem. Assuming partner has a stopper, I want the lead coming into him." Bart Bramley views it as "Delaying the guess but showing where my stuff is, which may be all that matters.  I can pass three notrump or bid spades over anything else."  Carl Hudecek is trying "To reach three notrump opposite five spades and club stopper.  Who knows where we will end if partner has five spades and no club stop."  YleeXotee points out that "It's not checking on heart fit, that's already denied, but it's letting p know I don't have club stop. so passing the buck."  Fleisher and Friesner feels they are "Indicating a heart stopper as opposed to guaranteeing an unbalanced hand with diamonds and hearts."  JCreech "Looking for 3 NT, but could end up in a spade contract."  BluBayou "I know bidding 3 !H  now is 'kitchen bridge' when not having 5+ length in diamonds,  but i don't see the harm.  If partner supports diamonds now, correcting to 4 !S  cant be that bad, so the first-impulse rebid of 2NT is not needed with our 10xx club holding.    The panel will probably split between a spade raise and that automatic  rebid in NT, though :( . I know I am not changing to a spade raise this month--after all  north may have 6-4 majors and then we can't get to 4 !HPhillip Alder frets "If partner bids three notrump, I won't know whether or not to pass (I will), but bidding three spades instead might drive us to an inferior four spades if North has only five."  In the end, Zia says "I know that most bid two notrump, but that doesn't mean it's right."

Although aware of the pitfall, Eric Stoltz still moves forward with raising partner's spades:  "This problem highlights the major downside of rebidding two of a major without promising six."


This concludes Part 2.  The last segment will be out when time permits.  Be sure to participate in next month's contest.  All are welcome.

On problem "B" I was curious as to why 3 !D was better than 3 !H. I remain in the dark.

Though Blu perhaps summed it up best with, "I will bid my one card." Still, at Matchpoints I thought the suit quality close enough to prefer the major over the minor. I still do.

Of the Panel, I found David Berkowitz the most persuasive.  "With a strong 6=3=3=1, North might be reluctant to correct three hearts but might well correct three diamonds."  But beyond that, Jock's bidding his one Hxxx suit was the other argument where I could find some solace.

I personally expect to go down regardless of choice, and the minus points per trick are the same in diamonds as they are in hearts.
