East's 2 NT response to their partner's double typically shows 11 HCP, two or more stoppers in the enemy suit, and no better bid. Close enough.

E/W take three Diamond tricks, four Clubs, one Heart, and one Spade, making three, or alternatively, N/S take two Spade tricks and two Hearts. South may lead a small Spade.

North suggests playing in 3 NT, but South, with a distributional monster, decides that a minor-suit game has to have as much play as game in notrump. N/S lose one Spade trick and one Diamond, making five. If West leads their stiff  5, N/S will make six. Oops. The best lead is the  A followed by a trump (duh). Declarer will win in their hand, cash the  A, ruff a Diamond with the  9, ruff a Spade, ruff another Diamond with the  Q, ruff a Spade to their hand, pull trump in two more rounds, and concede a Diamond, making five.

If you're North, make sure you don't simply raise to 4  after partner's 2  bid. Why not? Well, a 4  bid should say "Spades seem fine, partner, but I have nothing in my hand of interest." On this hand, North has second-round control in Diamonds, which might be all South needs for slam. That's not the case on this hand, since South is missing two bullets (Aces, not real bullets), but switch South's hand to  AKQJT8  AK T75  AK and see what they think about your singleton Diamond (they'd marry it).

N/S lose one Heart trick and one Diamond, making five. West may lead the  J.

N/S play NAMYATS (Stayman backwards for those of you who are Jumble challenged). NAMYATS uses bids of 4  and 4  to show strong openers in 4  and 4  respectively (basically eight running cards in the major and a side King). With 4  and 4  dedicated to boy-am-I-going-to-make-game hands, 4  and 4  can be purely preemptive. South's 4  bid asks North to bid 4 , and South can either pass that or proceed towards slam (as they intended to do here). West makes a reasonable double, but it sort of backfires as N/S are able to "right side" the slam. Heh.

N/S lose one Diamond trick, making six. West will lead the T. Declarer should not play the  J from dummy, since the chance that West has underled the  Q is exceedingly small. Better is to play for either the drop of the  Q or to try for a squeeze. When the  Q falls, the hand is over.

East isn't really interested in defending 1 NT, so they sneak in a 2  bid which buys the contract. E/W lose one Spade trick, one Heart, one Diamond, and two Clubs, making two. South may lead the T or a small trump.

E/W lose two Heart tricks and two Diamonds, making three. The right way to play the Club suit is  Q to the  A and then a ruffing finesse through North's assumed  K. South will lead the  K and switch to a small Diamond at trick two. North has nothing better to do than cash their  Q,  A, and exit with a trump.

South may choose to rebid 1 , but their hand looks notrumpy (that should be a word), so 1 NT isn't wrong.

N/S take three Heart tricks, one Diamond, one Spade, and two Clubs, making one. If West leads something that isn't a small Club, N/S will make two (or three if West leads the  A). On a small Club lead, East will insert the  K and declarer will win with the  A. The  Q is next, and West needs to hold off until the third round of Hearts, or again declarer will take eight tricks. When in with the  A, West will clear the Club suit by leading the  J. Declarer will win the  Q in dummy, cash the  K (pitching a Diamond), and run the  9 to West's  A. West will cash three more rounds of Clubs, but declarer will still get the  K and  A as their sixth and seventh tricks.

3 NT would be a far better contract, but it's not easy to end up there as West has a natural 3  invitational bid over partner's 2  rebid. Oh well......

N/S lose one Heart trick and two Spades, making four....as long as South finds a Diamond lead or switches to a Diamond when in with the  A. On the lead of the  3 (MUD), Declarer will win in their hand with the  A and play the  K. South will grab the  A and switch to the  8. Declarer will most likely hop with the  A, and North will ruff. North will have trouble getting back out of their hand. A Spade would go to the  Q in dummy, at which point declarer would cash the  Q and  J pitching the  5 and  6. The  7 is next finessing against the marked  K, making five. The  Q from North as an exit card after ruffing the Diamond is much better. Declarer will win the  K in their hand, ruff a Club with the  Q, cash the  Q (pitching a Diamond), and lead the  7. North will refuse to cover, and their  K will be the defense's third trick.

Knowing that Spades are splitting 3-1, declarer will need to take the Diamond hook for their 13th trick (i.e., pull trump in three rounds, cash the  A, play a small Diamond to the  K, cash the  K pitching their losing Heart, finesse against West's supposed  Q, cash the  A, and ruff the beer card with dummy's last trump).

East will probably return a Club to West's  Q, but with the  J9 in dummy, that will be the defense's last Club trick. West will probably exit with the  8 to dummy's  K. Declarer will clear the Spades (pitching a Club and a Heart from dummy). When the Diamond finesse loses, the hand is over.

You don't want to be in this slam. For 7 NT to make on a Heart lead (and yes, you're going to get a Heart lead), you need (1) Clubs to be 3-3, (2) Diamonds to be 3-3, (3) the  Q to be in the North hand, and (4) the  Q to be in the North hand. Let's see....add stuff....do a take away.....carry the six....that works out to approximately 0% (Ed. 0% is not quite correct. The actual probability of E/W taking 13 tricks is 36% × 36% × 50% × 50% = 3.24%. The chance that 6 NT makes is basically the same, since the moment that declarer loses the lead they're going down).

If declarer is one of those "Well, we're only in four so why should I try for overtricks?" type of players, E/W will probably make four (five Club tricks, two Diamonds, one Heart, and two Spades). If declarer is one of those "Well, we're only in four so why shouldn't I try to make seven?" type of players, E/W will make seven. Heh.

North passes throughout with 18 HCP. If you were North, did you take a bid? Hopefully not, since you know with 100% certainty that partner has a zero count. Let's look at North's thinking at each point during the hand:
1) After West's 1  bid, North knows that East has to take a bid. No reason to bid yet.
2) After West's 2  artificial relay, North knows that East will bid 2 . Still no rush.
3) After West's 3  bid, E/W have claimed somewhere around 23 HCP. Add that to the 18 that North holds, and their partner has ________ HCPs. (You fill in the blank)

E/W lose one Club trick, one Diamond, one Heart, and one Spade, making three. North can never get to their partner's hand to get a Spade lead through. North may lead a small trump. Declarer wins in dummy with the  K and leads the  K, won by North. North has nothing better to do than to cash out.

Can you blame West for doubling the final contract? Their partner has doubled and bid a suit, and they hold five trumps with two honors. They should be ashamed if they don't double.

N/S lose one Club trick, one Diamond, and two Spades, making three doubled for +530. East will lead the  K and probably switch to the  8 at trick two (MUD). Declarer will win the  K with the  A (West has the T so it doesn't hurt to cover), pitch a Club from dummy on the  Q, and lead the  K. East wins the  A and has nothing better to do than to continue with another high Club, ruffed in dummy. A Diamond ruff, a Heart ruff, a Diamond ruff, a Heart ruff with the  K, a Diamond ruff with the  J, and the  A add up to nine tricks. Nicely played!

If South bids 7 , East should bid 7 . Why is that? Well, there's no way that South would sacrifice in seven holding the  K, so suddenly the finesse has more appeal. Heh.

E/W lose zero tricks, making seven. North may lead their stiff  3. Declarer will win with the  Q and lead the  Q. When the  K shows up, the hand is over.

NOTE: Here's an interesting agreement to have when you hold a known void (it's clearly Diamonds on this hand). If you have two or four keycards, you'll still bid the fifth step above your partner's keycard "ask" (5  on this hand). If you have one or three keycards, rather than bid your void (which partner already knows), make a more informative bid. There are four available bids above 5  (5 NT, 6 , 6 , 6 ) on this hand. Bidding each of those should have a special meaning:

5 NT - Void in Diamonds and the  K (the "ask" suit)
6  - Void in Diamonds, the  K, but not the  K
6  - Void in Diamonds, the  Q, but neither black King
6  - Void in Diamonds but no  Q or black King

Talk this over with your partner.

East is able to show both of their suits on the auction, and West has an easy raise to game. If West had 20+ HCP, they would have started with a takeout double and then cuebid the opponent's suit with their rebid.

E/W lose one Spade trick and one Heart, making five. North will lead the  Q.

E/W play Kickback, so you might expect West to use 4  as their keycard ask on this hand. The problem with that is that East may think that 4  is to play and pass. That would not be a good thing. To hand hold their partner, West simply reverts to 4 NT as their keycard ask on this hand. Look for opportunities to not torture your partner (unless your partner is a tool, in which case torture them as much as possible).

West has no reason to place the contract in 7 . If 7 NT goes down because of a bad break in Hearts, then 7  will fare no better. E/W take one Spade trick, six Hearts, three Diamonds, and three Clubs, making seven. North will lead the  7.

North's 2 NT bid denied a four-card major, so South is 400% sure that North has two or more Diamonds.

West will probably lead the  J won in dummy with the  A. With dummy entries at a premium, it's reasonable for declarer to lead the  Q from dummy. East has no reason to cover, since they know that their partner has at most one Diamond. When the  Q holds and the T falls, declarer should switch gears and lead the  8 to the  J. When that holds, declarer can cash the  A, ruff the  9 with the  6, and take the marked finesse for the  K, making seven. Nicely played!

East has to bid after their partner's support double, and 3  looks reasonable. West takes a bit of a chance bidding 3 NT, but they have a very nice hand, and that contract should have play.

E/W take one Spade trick, two Hearts, one Club, and five Diamonds, making three. North will lead the  Q, and declarer (if they're wise) will allow it to hold. The  5 is next covered by the  9, T, and  A. The T is led to the  J and declarer holds their breath. If South has the  A, E/W are going down a bunch, but South didn't bid 1  over East's 1  bid--they bid 2 , a weak jump overcall. They aren't as likely to hold the  A as their partner is. When that bit of logic proves true, and the  J wins the trick, declarer places the  9 on the table.

South plays the  K, declarer wins the  A, and continues with the  Q. When South shows out, declarer switches gears and leads the  4 towards the board. North should rise with the  A and lead the T. Declarer wins with the  J and plays a fourth round of Diamonds to North's  8. With nothing left but round-suit cards (Hearts and Clubs), West's best play is to lead a Heart into declarer's  AQ tenace. Declarer will concede a Heart at trick 13.

North's 1 NT rebid doesn't deny a fourth Spade, since North might have a hand like  8765  KJ6  KJ76  AJ9. Rebidding 1  with that hand seems silly, since the hand is (1) flat and (2) looks amazingly like it belongs in a notrump contract. When North denies a fourth Spade, South is content to bid the notrump game.

N/S take four Spade tricks, three Hearts, two Diamonds, and one Club, making four....as long as East leads something besides a Club. On a Club lead, N/S might struggle to take nine tricks. More than likely East will lead a Spade. Declarer will win the Spade lead in hand and lead the  J to West's  Q. West can't exit with a Club without giving declarer an extra trick, so they'll probably exit with another Heart. After winning the  A and cashing two more rounds of Hearts, declarer will lead the  Q from dummy. West will hop with the  A and exit with a small Diamond, but they aren't going to enjoy discarding for the rest of the hand. Luckily for them, declarer won't be able to put them in with a Diamond after cashing their major-suit winners (i.e., they'll be in dummy at that time), so West merely has to insert the  J to knock out the  A when Clubs are led.

South doubles once the auction looks like it's ending, and North bids the obvious. N/S lose two Spade tricks, one Heart, and one Club, making three. East will lead the  Q. With West being marked for the  K, declarer should play East for the remaining high cards. The best way to play the Clubs, when East is known to hold the  K, is  A and then small from both hands.

West shows their Spades the first time, but decides that 4  might have more play than 3  when the auction comes back around.

E/W lose one Club trick, one Heart, and one Spade, making four. North may lead the  5 (MUD). Declarer will win the Diamond and lead a small Club towards dummy. North will hop with the  A and exit with another Diamond to declarer's  A. At this point, declarer should lead the  9 towards dummy. If North splits their honors, declarer will allow them to hold the trick (i.e., South is the danger hand, as declarer would not relish a Spade lead through their  Qxxx). North should exit with a trump, won in dummy. The  A is next followed by a Heart ruff and the  2. If North plays low, declarer will win the  7, ruff dummy's T, and the two high Clubs and  A in dummy will be the ninth and tenth tricks.

If North inserts the  J or T when the  2 is led (more likely), declarer will play low from dummy and allow North to hold the trick. North has the unenviable choice of leading a Spade away from their  KJ giving declarer the last five tricks with the  Q,  A, Heart ruff, and  KQ, or leading a Diamond allowing declarer to discard dummy's other small Spade while ruffing in hand, play a Spade to the  A, ruff a Heart, and cash the  KQ. Well done!

East risks life and limb by passing West's forcing bid. Don't do that. That said, what else should East bid? North has claimed the black suits, they don't have a Spade stopper for notrump (nor do they think their partner does when they didn't double 2 ), they know that Hearts are breaking at least 6-2-0, maybe worse. If your partner is bigger than you, don't pass.

E/W lose three Spade tricks, one Diamond, and a Heart ruff, down one. North will lead the  J, won by West with the  A. West's best continuation is a small trump, ducked by North and won in dummy with the  9. Another trump is led, won by North with the  A. The  A is next followed by a Spade to the  K and a Heart return for North to ruff. The  Q is the defense's fifth and final trick.

N/S take four Diamond tricks, two Hearts, one Spade, and two Clubs, making three. East will most likely lead the  Q. Declarer should win and cash the  A and  Q. If East ducks the  Q, declarer will play the  A and T to the  J and  K. A third Club establishes the suit, and declarer still has an entry back to dummy (two Diamond tricks, two Hearts, one Spade, and four Clubs). If East takes the  Q with the  K and knocks out declarer's last Heart stopper, then the  K is an entry to dummy's good Diamonds.

East bids 4  knowing that their partner won't pass holding a singleton or void in Spades.

E/W lose one Heart trick and one Diamond, making five....if South leads a trump. South will probably lead the T, and as long as declarer finesses North for the  Q (on the obvious Spade return) and South for the  K (to pitch their losing Diamond), they'll make six. The hand record says that it makes six even on a trump lead, but that's on double-dummy lines (finessing against South for the  KT9x). South will lead the T (duh).

West sneaks in a double on the second round of bidding in case the auction is dying. East is more than happy to introduce their Diamond suit (i.e., more than happy means ecstatic). E/W lose one Club trick, two Hearts, and one Spade, making three. South will lead the  3 (low from an honor). North will win the  K and return their stiff  4. If declarer plays low on the Spade shift, they deserve to go down (Did you not hear the auction?!?!?).

N/S meander into a not-very-good slam which happens to make. Sigh.

N/S take five Spade tricks, four Clubs, two Hearts, and one Diamond, making six. West's lead is irrelevant, since N/S are always going to lose a Club trick. Lead the  Q if it makes you happy.

E/W take two Spade tricks, two Hearts, and four Diamonds, down one for –50. If North finds the unlikely lead of the  A, E/W will be down two. If you're South, make sure you say something like "It doesn't seem like anybody bid Clubs, did they?" before your partner has a chance to lead. If you don't do this, North will lead the  Q. South will signal (loudly) for a Club shift the first time they're able (fourth round of Diamonds). Declarer will be wise to cash out.

Oops. E/W lose two Heart tricks, one Diamond, three Clubs, and one Spade, down one doubled for –200. North should lead the  3. Declarer will cover the T with the  A and lead the  A and another Club in an attempt to ruff a Club with dummy's last trump. South will win with the  K and return the  J (smothering the  9 in dummy). Declarer will win with the  K, cash the  A, and exit with a Diamond to North's T. There's no way for the defense to prevent declarer from eventually being able to ruff something with the  6, but the  7 will be the defense's sixth trick.

N/S have the agreement that North's sequence of bids—Stayman followed by a minor-suit rebid at the three level—shows a weakish hand with a four-card major and a six-card (or longer) minor. South is required to pass North's 3  rebid.

N/S lose one Spade trick and two Diamonds, making four. East may lead the  4 (out of desperation).

That's a negative billion percent game (Ed. It is not a negative billion percent but much closer to 50% × 50% × 50% × 36% = 4.5%). South may lead a small trump or the  6 (MUD).
