Shirley: This hand was published on Page 48 of the December 2004 ACBL Bulletin in the outstanding series “Boehm on Bridge” by August Boehm.   His emphasis is on bidding, but the hand is a rather spectacular play/defense deal as well.  The vulnerability was intentionally left blank.

Here are the problems for our readers to solve.

Part A: Bidding.  How would you recommend that the bidding proceed (a) with neither side vulnerable; (b) with both sides vulnerable.

Part B: Single dummy play:  Assuming that the bidding went as in the Boehm column below, how should the hand be played and defended after (a) if the defense plays two rounds of Diamonds or (b) If the defense plays one Diamond and shifts to Hearts at trick 2?  Bottom line: Should 4C make or go down?

Part C: Double dummy:  Can 4C be defeated by double dummy play and defense against an opening Diamond lead?

The bidding per the Boehm column:

West                North               East                 South

-                       1D                   3C                   3D

4C                   P                      P                      Dble

P                      P                      P

Solutions:

Part A: The opening 1D bid, 3C overcall, and 3D raise are perfectly correct at any vulnerability.  I personally do not care for West’s 4C call if vulnerable.  You could easily have 5 losers off the top as 3S and 2D.  Even if they do not double you, you could be off 200 in a part score hand.  If non-vulnerable, the 4C raise is more sensible but Pass is also fine.

Summary of 4C:  Vul, definitely not ;  Non-Vul: 4C and Pass are both correct.

            I definitely do not like the Double of 4C at any vulnerability, but especially not against non-vulnerable opponents.  Here is the balance sheet:

In favor of the double (vul) (You expect to beat this by no more than a single trick.  Setting 4C gets you 200, which will beat Diamond part-scores, assuming 3+ D makes as expected.

Against the double:  (1) -130 beats a potential -140, but -510 or -710 loses to -140.  Let us wonder about partner’s distribution.  Clearly, partner has exactly one Club.  With no Clubs (4-4-5-0 shape), there is no way partner will fail to bid 4D directly over 4C.    Note that you have 2-2 in the majors.  Do your opponents have an eight card major suit fit?  They do, unless partner is specifically 4-4-4-1.  If  partner has any other shape, your double might lead to 4C doubled making, whereas many will play 3 of a major for 140.  Your double would convert the -130 (4C making) from a winner against -140 to a loser (- a big number). (2)  Another reason, which will get very clear later, is that your double may guide declarer to the winning line of play. 

How about bidding 4D?  You appear to have 2 tricks on defense (one sure Club and a likely Spade).  If partner can come up with two more defensive tricks, the set will occur.  Looking at the hand from an offensive perspective, you appear to have 8 tricks in the minors (6D+2C ruffs).  Assuming Diamonds are solid, you need to hold your 4 major suit losers to two.  Either way, you need two tricks from partner, but they have to be faster tricks on offense than on defense.  You might score a defensive third round of a major on defense, but that is unlikely on offense.  Thus, at any vulnerability, I would rather defend despite the old adage of going to the level of your trump (presumed to be at least 10, that is, the 4 level).

Summary of Bidding ratings over 4C:

Pass: best

Double: second best vs. Vul opponents, worst against NV opponents .

4D: Worst vs. vul opponents , second best vs. non-vul opponents .

Part B:  Against 4C doubled, declarer should place South with the C-QJx.  North’s failure to bid 4D immediately over 4C realistically precludes that hand from being void in Clubs. 

There are two options for long range plans: Since you have two sure minor suit losers, you have to avoid two major suit losers.  If Hearts are 3-3, you can play to lose a Heart and pitch the Spade loser on the long Heart.  But if Spades are 3-3, you can get rid of the losing Heart on a Spade.  Moreover, Spades offers other chances, for example if someone has KQ doubleton, the J can provide a winner.  If South has S-K10 or S-Q10, a ruffing finesse against North can develop.  And as we shall see, Spades offers hope to set up the 5^th Spade even when they break 4-2.   So our plan will be to play on Spades.

• (a) If the defense starts with two Diamonds, ruff the second, and play the SA and S8 to South’s SK. (South cannot unblock the SK under the SA because a ruffing finesse through North will result on the third round of Spades.) South now plays the H9 (better than the CQ). Dummy wins and the third Spade is ruffed with the C9. South has only losing options: (1) overruff and return another Heart. Thanks to your penalty double of 4C, declarer now ruffs the 4^th round of Spades with the CK, and leads a trump to the A8 over your Q3, and pulls your two trump and partners one trump via this finesse, and enjoys the 13^th Spade, pitching East’s last Heart. In all, declarer wins 2S, 2H, and 6C for 10 tricks. (2) If South declines to overruff the third round of Spades, say pitching the last Heart, declarer simply plays the CK, C to the CA, and ruffs another Spade, setting up dummy’s 5^th Spade. South can ruff now or pitch, but declarer puts South right back in the middle with the second round of Hearts (catching air if South ruffs) or winning and playing the good Spade if not. Either way, South loses one trump, 1S, and 1D but takes the rest.

• (b) If the defense finds the spectacular Heart shift at trick 2 (almost impossible for North to overtake and return the HQ.) That would prove quite embarrassing if two rounds of Hearts are played with East pitching a Diamond on the second. North cannot visualize a six card Diamond suit in the South hand. North should simply encourage Diamonds at trick 1. South knows the next Diamond will be ruffed and might appreciate the race for the winning major and smartly shift to a Heart. If this happens, the defense can prevail at single dummy play. Again, East should go after the Spade suit by playing the SA and another Spade. South should win and play a Second Heart. Declarer will win and ruff a Spade with the C9 at this position with South to play and the highlighted underscored cards played to this trick already.

                                    C-QJ3

If South overruffs, as 99% of Souths would do in practice, declarer should make the hand (again thanks to the penalty double), by ruffing the Diamond exit, leading a Club for a finesse, ruffing the 4^th round of Spades with the K, and pulling the last trump ending in dummy to enjoy the SJ (5^th round of Spades.) Ten tricks are 2S, 2H, and 6C.

Now see how different the hand is if South pitches a Diamond on the diagrammed trick.  The defense cannot be stopped from earning a Heart and a Club to go along their trick in each of Spades and Diamonds for Down 1.

Footnote:  If North overtakes the opening lead and return a Club, the hand can also be set.  Assuming the club goes to the CJ and CA, South will have to reject not one, but two opportunities to overruff in Spades.  Either overruff is fatal to the defense, but if both are rejected, declarer fails by a trick.

Part C  Double Dummy:  No! After a Diamond lead and a Heart shift (or any other play such as a Club shift from North), 4C can indeed be made. 

First, let us see how declarer succeeds with a Diamond lead and Heart shift. This is strictly double dummy and is not a really good play against a random EW selection given the bidding.  Declarer wins the Heart in dummy, ruffs a Diamond (key play) and plays the SA.  (a) If South unblocks the SK, run the S8 to North’s S10, and later take a ruffing finesse of the S-J9 through North’s S-Qx to set up a Spade for a Heart pitch, while South can ruff with the natural trump trick if s/he wants. (b) If South plays a low Spade, lead a trump toward the A8.  South must split honors.  Now put South in with the SK, to find the perfect endplay: (South to lead)

If South leads a Diamond, dummy ruffs, and the Heart loser disappears.  But if South exits in trump, the trump loser disappears.  Both roads lead to 10 tricks.

This deal occurred Tuesday, 12/14/2004 at the Gator Bridge Club.  Edwin Kantar has requested to use a modified version of this for his Test Your Play column in the ACBL Bulletin and has contributed to the analysis.

(1) Regular Stayman

The play at Table 1 went as follows:  West led the C3 to the C2,  CK and CA.  Declarer led a low Spade to the Q and K (West pitching the C4). The C8 was returned to the CQ, and the C6 was returned, to the C10, ruffed low by East and overruffed by South.  Declarer pulled two more rounds of trump,  conceded a trump to East, and claimed a total of 10 tricks: 3S (including the overruff). 3H,3D, and 1C.

The play at Table 2 went a bit differently.  West led the C6 to the C2, CK and CA.  Again, the next trick went S2 (C3), SQ, SK. As before, the C8 went to West’s Q. But this time, West switched to a low Diamond.  Declarer won the DA in his hand, played a low Diamond to the J, and next played the C10.  East pitched a Heart on this, as declarer sluffed the DK.  Now the DQ was played East following.  Finally, declarer played a low Heart to the HA, and a Heart back to the HQ.  East ruffed low and exited with the 13^th Diamond.  Since East still held S-1094, against North’s A86 and South’s J75, declarer had to lose a Spade trick along with the three tricks already lost for down one.

Solution.

Bidding Commentary.  Both North players get a pat on the back and a kick in the shins.  They made good decisions not to investigate slams.  With a 4-3-3-3 and 11 points (31-32 for the partnership), slam is against the odds.  However, both players get a mild error for looking for the 4-4 major suit fit.    Because NS are close to the slam zone, and because of the flat distribution, my expectation (without seeing the South hand) would be that most hands will produce the same number of tricks in the potential 4-4 Spade fit  as in NT (probably 11).  A bad Spade split may be irrelevant to NT (as it is in this hand).

Curiously, the North using Puppet Stayman made less of a bidding error than the pair using regular Stayman.  Whether or not the major fit gets established, the regular Stayman bidder gave comfort to the enemy in providing gratis information about the shape of the 2NT opener.  In this case, it was showing 4H along with the 4S.  A full explanation on Puppet Stayman can be seen at http://www.gainesvillebridge.com/.

Play commentary. 

At Table 1, West  was entirely  responsible for the failure to defeat the hand!  EW were on the right track, but East’s understandable ruff of the third Club, instead of pitching a Heart, led to the hand being made.  West led her 6^th best Club, instead of her fourth best (as was led at Table 2), and this fooled East into thinking it was perfectly safe to ruff the third Club low. Here is the very dangerous layout that East must fear (NS needing all the remaining trick but one.)  We presume that East, instead of ruffing low, sluffs a Heart on the C10, so the last trick was won by Dummy’s C10:

                  North:

                  S-A86

                  H-Q75

                  D-QJ6

                  C-

West:                                       East

                   D-AK7

                   C-x

Declarer cashes 3 Diamonds, returns to hand with the HK, and leads a Club, ruffing with the S8.  (a) If East overruffs, an endplay results.  If East exits in Diamonds, South pitches his last Heart and ruffs in the dummy.  The SA is now led, and South has S-J7 comfortably situated over East’s S-104 to make the last two tricks, overruffing whatever East plays on the Heart lead from dummy.  (b) If East sluffs a Diamond instead of overruffing, leaving East with nothing but trump.  A low Heart is led from Dummy, and  East ruffs the Heart low. This is the holding with East to lead:

Whether East leads low or high, South takes the last three tricks.

Conclusion at Table 1:  East looked bad, but it was West who messed up the defense by dishonestly leading her sixth best Club.

At Table 2, West again made a key defensive error.  With the honest lead in Clubs, East will know that West held six.  (The bidding also helps here since South is known to be 4-4 in the majors and has at least two Diamonds for his NT bid.) When in with the second round of Clubs, West’s proper return is yet another low Club (having led the C6, pitching the 3, winning the Q, and playing the 4), all players should know that West started with a six card Club suit.

Let us see how West should know to return another Club.  First, dummy has 11 points and South 20-21.  Therefore, your side has 8-9 points.  West has seen the SK, CK, CQ, and is staring at the HJ.  That totals 9 points, so partner has no red suit honor.  Any tricks have to come from the trump suit.  Partner has 5S and needs to safely ruff one low and hopefully make another.  From the Stayman auction, you know partner has exactly two Hearts and declarer four.  So if partner can pitch a Heart on the Club, the early low Heart ruff looks promising, at a time when East can exit in a non-trump suit.  Declarer may try to cash a lot of tricks and force East to ruff at the end to lead away from a good Spade holding.  The Heart pitch eliminates that chance.

Fortunately for the defense, Declarer blew the hand by playing a Club himself, far too early.  Declarer was not watching the Club spots carefully enough.  Charge him with a serious play error.  Here is how the play should go from the point where West exited with a Diamond, rather than a Club:

                  North:

                  S-A86

                  H-Q75

                  D-QJ

                  C-10

West:                                       East

H-J642                                                H-109

D-105                                      D-982

C-974                                      C-

                   South

                   S-J75

                   H-AK83

                   D-K7

                   C-

Recognizing that it is virtually hopeless if East has a singleton in either red suit, declarer should play two Hearts and one more Diamond ending in dummy, before playing the C10. (NS can afford to lose only one trick from here on)

                  North:

                  S-A86

                  H-7

                  D-Q

                  C-10

West:                                       East

S-None                                    S-10943

                   H-K8

                   D-K

                   C-

East has only losing options:

• (1) Ruff the C10 low. Declarer overruffs plays two trump (SJ then SA) ending in dummy, and plays winners until East ruffs.
• (2) Ruff the C10 high. South pitches the H8, and makes the rest with the help of a trump finesse through East.
• (3) East pitches while South pitches the DK. Now the DQ is won in dummy and the H7 is led at this position:

                  North:

                  S-A86

                  H-7

                  D-

                  C-

West:                                       East

                   South

                   H-K

                   D-

                   C-

East successfully ruffs low, but NS win the last 3 tricks as East is endplayed in trump.  East can lead the S10, won in dummy, but the S-94 are trapped under the S-J7.

Summary at Table 2:  The defense was poor by West, and declarer stumbled by trying to cash the Club too early.  He was indeed unlucky Clubs were 6-2 rather than 5-3, but the lead of the C6 was a warning shot that this might be the case.

By Jon Shuster

Shirley: Today, I am going to break with the usual tradition of watching Gainesville Bridge Club members, and honor a request to discuss Puppet Stayman.

This convention was invented in the days when few people opened 1NT or 2NT with 5 card majors.  The sole purpose of this convention was to avoid transmitting information that is potentially a gold mine for the defense and a disaster for the NT opening side. 

Let me illustrate what happens in classical Stayman auctions:

South                           North

1NT(15-17)                 2C

2H                               3NT

P

West leads the Diamond 2 (4^th best), won by declarer.  Declarer leads a Club to dummy, West giving count.  As early as trick 2, East can infer declarer’s exact count in all four suits.  This makes defending a breeze.

Now let us go back to a Puppet Stayman auction for the same hand:

South                           North

1NT(15-17)                 2C (Puppet to 2D)

2D                               2H (Shows the major you lack)

3NT (Maximum)         P

Defenders have no idea of South’s shape, except South does not have 4S.

Here is how classical Puppet Stayman works: (I will add some options for greater accuracy later):

If you bid 2C over 1NT, you either want to play 2D, or you have at least INVITATIONAL values for game, nearly always with at least one 4 card major.  Just remember that the responder will NEVER be the first to bid a real suit, as s/he wants the opener to ALWAYS be declarer.

• (1) Classical Puppet Stayman is initiated by 2C over 1NT, a temporary transfer to 2D
• (2) Opener must bid 2D (The option of showing a 5 card major is bad bridge!!)

(3A) Responder can pass (if 2D is where you wanted to play)

(3B) With one 4 card major bid the one you do not have. (2H shows Spades while 2S shows Hearts.)

(3C) With both 4-4 in both majors, bid 2NT (invitational with 8-9 points) or 3NT (with 10-14 points). 

(3D) (Optional) With at least 5-4 in the majors and a game going hand, bid 3C, the start of Puppet Smolen.  If you have never heard of this, read no further on this topic).  For others, we will amplify later.

(3E) (Optional)  With an invitational hand with long Diamonds:  e.g.  S-xx H-xxx D-AQJxxx C-xx, bid 3D.

(4). Opener’s responses:

 1NT-2C

  2D-2 Major

    ?

(4A) If you have a minimum and 4 cards in the suit implied by partner, bid the suit at the cheapesat level:

 1NT-2C

   2D-2 S (Shows Hearts)

  3H

(4B) With a maximum and a fit, bid game in the agreed major:

1NT-2C

 2D-2 S (Shows Hearts)

4H

(4C) If you have a minimum and no fit, bid 2NT

(4D) If you have a maximum and no fit, bid 3NT.

(4E) If partner bids 2NT (Both majors and invitational)

 Bid 3 of your 4 card major with a minimum and a known 4-4 fit, bid 4 of your major with a fit and a maximum.  Pass 2NT with no fit and a minimum, bid  3NT with no fit and a maximum.

(4F) If partner bids 3NT (both majors), convert to 4 of the appropriate major with a 4-4 fit.  If you have 4-4 yourself, pick your better suit.

A quiz:

Here are some examples and tell me how each hand should be bid: (Give both players bids) West deals and opens 1NT (15-17):

#1 

West                                                          East

S-AK74  H-KQ3 D-KJ8 C-532                S-108 H-A1073 D-A1062 C-107

#2

West                                                          East

S-AK74  H-KQ3 D-KJ8 C-532                S-108 H-1073 D-Q10986 C-1076

#3

West

S-AK74 H-AJ3 D-843 C-QJ5                  S-Q1054 H-10982 D-AK C-1042

#4

S-AQ542 H-A9 D-KQ2 C-J72                 S-KJ6 H-Q1053 D-A9 C-7543

Solutions:

#1

West                            East

1NT(15-17)                 2C

2D                               2S

2NT                             P

This is the perfect contract.  Even if the opponents can run 5 Clubs, you have to make the rest. If the HJ falls or you can find the DQ you have at least 8 tricks for a great score.  It is true that 3NT has a slim chance, but if you are in 2NT and make 3, you will get a great board.

#2

West                            East

1NT(15-17)                 2C

2D                               P

Nice to be able to get yourself out of 1NT.  If the holder of the DA has 3 or more Diamonds (better than 50-50 chance), you can only make two Diamond tricks at NT.  In 2D, you will make the hand if an opponent kindly plucks down the HA, or if the hand with the HA is on the right of the 1NT opener.

#3

West                            East

4S

(This hand is from Monday, December 13).

East hand is way too good to bid only 2NT.  It has 9 excellent HCP plus three 10′s.  You need to bid game even opposite a minimum.  It is worth 10 points in a major.

West may not show a 5 card major.  It would defeat the principal of not showing anything to your opponents.  It always loses in hands where partner does not have exactly 3 Spades (over 50%), and gains about as much as it loses when indeed partner has exactly 3 Spades.  I love 3NT hands with an unannounced 5-3 fit, be it a major or a minor.  On page 41 of the ACBL November 2004 Bulletin, Puppet Stayman is grossly misleadingly called a gadget to reach 5-3 major fits over 2NT openers.  That motivation indicates a total lack of understanding of the inventor’s concept of keeping information about the NT opener as private as possible.

Note that 3NT is cold  (except in the extraordinary event that Clubs are 5-1 with the opening leader having 5 or if Spades break 5-0). Further, 4S needs a lot of luck to make.   Clubs need to be 3-3 and the Hearts have to lie in such a way that neither defender can lead them (North must hold the HJ and South the HK.)

Puppet’s Smolen.

If you have not played Smolen, you can ignore this.

Smolen  within Puppet starts as follows:

1NT-2C

2D(forced response)  3C

3C shows at least 5 cards in one major, at least 4 cards in the other, and is 100% game forcing.

Opener’s responses:

3D: Asks for responder’s  4 card major (if s/he has one as a puppet bid).  More on this below. You only bid this if you need to know the answer.

3 of a major sets the trump suit.  (You may not jump to game as partner may need the room for slam investigation.  After you agree in trump, all bids in a different suit  are cue bids and 3NT shows slam interest marking time.)

3NT: No interest in playing in a major: Nearly always,  it shows doubletons in both majors.

Now let us look at this sequence

1NT-2C

2D-3C

3D ?

Bid the suit you don’t have 5 of.

3H shows 4H and 5+ Spades.

3S shows 4S and 5+Hearts

3NT shows exactly 5-5 in the majors. Insist on a suit whenever you have 6-5 in the majors.

Here are two ways to handle 6-5 in the majors, but be sure to discuss this with partner.  Play only one of these:

• (a) Bid your 5 card major, pretending it is a 4 card major, and then if partner bids 3NT, transfer into your 6 card major.

(b) Optional: 4C over 3D shows 6H-5S and 4D shows 6S-5H

Note: Unlike transfers, where you transfer in one major and bid the other, responder never gets to play the hand, regardless of which major winds up as trump.

Note: Over opener’s 3NT, 4D is a transfer to Hearts and 4H is a transfer to Spades.  (You will never bid a real suit, so partner should not ever forget).  Do not leave 3NT in with a 6 card major.

Opener must never bid 3D if you know where you want to be.

1NT-2C

2D-3C

Do you bid 3D to inquire about the majors?

Ex 1:

S-AQ2  H-K1042 D-A10 C-KJ43

No! Just bid 3H.  You should not disclose interest in Spades.  It does not matter whether partner has 5S and 4H or the reverse, Hearts will play better.

Ex 2:

S-KJ3 H-A104 D-AKJ64 C-42

Yes! Here, you want to play in your 5-3 major, so it is essential to bid 3D.  You will bid 3S over 3H (5-3 Spade fit) or 4H over 3S (5-3 Heart fit).  You will skillfully play the hand, of course.

Ex 3:

S-K1032 H-AJ75 D-AQ  C-Q92

Yes! Here, you should bid 3D and play in your 5-4 fit.  It is true that 4-4 fits often play better, but playing in the 5-4 fit is usually safer when the 4-4 suit breaks poorly.  Playing in the 5-4 often requires less skill to make the optimum.  The other advantage is that if you ask for the 4 card suit and play in it, your partner plays the hand, destroying the transfer principal.

Ex 4:

S-KJ H-A10 D-KQ1043 C-QJ75

No!  Bid 3NT.  You have no interest in playing in a major.

Quiz:

How should these hands be bid?

West (dealer): S-KJ H-A10 D-KQ1043 C-QJ75

East:  S-Q109754 H-KQ52  D-95 C-6

Solution:

1NT -2C

2D-3C

3NT-4H (Transfer.  Remember, responder never plays the hand)

4S-P

It would also be acceptable to just transfer into Spades and go straight to game in Spades, forgetting about the Heart suit.  This East hand must insist on game, and with a 6-4 shape opposite 1NT, has absolutely no interest in NT.
