West opens 1NT. East jumps to 3S, showing a single-suited hand with slam interest. There is no need to use a transfer on such a strong hand. Alternatively, East might transfer and then jump to show his singleton, but when the singleton is an Ace or King I wouldn't bother to show it -- partner will discount values in that suit and expect you to have more outside. West rebids 3NT, denying spade support; with support he would cue-bid his cheapest control or raise to 4 with a very poor hand for slam. East cue-bids 4C, looking for a heart control. This shows why you don't want to require first-round controls for the first round of cue-bidding; Blackwood can sort out whether you are missing two first-round controls. Playing Key Card; I like to think of East as "borrowing" one of his trump key cards for the cue-bid. Partner won't go overboard without checking on key cards. East's cue-bid confirms at least 6 trumps; a 5332 hand would raise the notrump.

West, with three key cards and four quick tricks, should assume he has everything partner needs and proceed with 4NT. East replies 5H (two key cards, no Queen) or 5D (Blackwood, one Ace.) Missing the Queen of trumps West signs off at 6S. Playing Blackwood West should continue with 5NT (confirming all the Aces) then 6S over partner's two-king reply. East might correct to 6NT; with a possible spade loser, there will be the same 12 tricks if partner has either the King of hearts or the Queen (for an extra stopper) and either minor suit Queen, or if they don't lead hearts.

Most pairs reached 6S.

Board 15 South Deals N-S Vul	♠ K 9 3 ♥ 10 6 5 3 ♦ 10 7 4 3 ♣ 10 2
♠ Q 8 5 2 ♥ A K Q ♦ K 2 ♣ A K J 6	N W E S	♠ A J 4 ♥ 8 7 4 ♦ A Q 8 5 ♣ 9 7 3
	♠ 10 7 6 ♥ J 9 2 ♦ J 9 6 ♣ Q 8 5 4

West opens 2C, planning a 2NT rebid to show 22-24 hcp. Depending on your methods:

(a) Playing 2D negative, East jumps to 3NT, showing a balanced 10-12. West probably bids 6NT to avoid any confusion over Stayman/Gerber/Blackwood in this rare sequence.

(b) East bids 2D waiting, West makes his planned 2NT rebid. East raises to 6NT.

(c) East bids 2NT "steps", showing 10-12. West rebids 3NT to show his balanced hand; East cannot pass with so much strength. East raises to 6NT.

(d) East bids 2D semi-positive, promising an Ace or King or (in some styles) 4+ hcp. West rebids 2NT; this is unlimited in strength (since 2D created a game force) but again East computes 22+11= 6NT. With interest in a major suit East could use Stayman or transfers over 2NT.

North probably leads a heart; there is little to choose between the red suits but no one investigated major suits and partner did not double an artificial 2D. Partner has a few points and any lead may finesse him but there is nothing safe; leading from length may avoid setting up a suit for declarer. West counts two spades (with a possible loser if the finesse fails), three hearts, three diamonds, and two to four clubs; ten sure tricks and extra chances in spades, clubs or diamonds (on a squeeze.) I won the heart and immediately led low to the Jack of spades; if this lost I'd need the club finesse to work and one of the two black suits to break 3-3, with squeeze chances if they don't. In fact, someone must attempt to guard two suits. When the Jack won I promptly finessed in clubs. That won, bringing the trick total up to 11. If the clubs were 3-3 that would provide the 12th trick, but if not I might need to lose a trick to set up the fourth spade or a squeeze, so I played a low spade from both hands. This would not be safe if I'd tried the clubs first and someone had the fourth winner in that suit. The fourth spade set up for trick 12. If you did test the clubs first, the correct play would be to lead the Queen of spades and duck North's King, since North would've shown out in clubs. But ducking the spade first rectifies the count for a possible squeeze, while still allowing you to test both black suits first for a 3-3 split.

East opens 1D; a 1C opening might prove embarrassing if South overcalled 1H and West bid 1S. I'm sure many Wests simply bid 3NT, but this will look silly if they rattle off five spade tricks and partner's hand is cold for 6C: x xxx AK10xx AJxx. West responds 2C and East raises to three. West probes for 3NT with 3H; East would bid 3NT with a spade stopper or perhaps 3S (fourth suit) with a partial stop or even three small. With a singleton spade East would bid 5C or perhaps splinter 4S. Holding two small, East bids 4C and West raises confidently to five. Well-bid! Five of a minor is usually a poor matchpoint spot but on today's hand 5C is nearly cold while 3NT is odds against. "Nearly", however, wasn't enough this time: the defense cashed A-K of spades and switched to the Jack of hearts. No reason to risk the finesse; a heart, four diamonds, five clubs and a spade ruff will produce 11 tricks. Win the Ace, play a trump -- disaster! Although the recap claims 5C is makeable, I haven't been able to puzzle that out. I tried clearing the QJ of diamonds, ruffing a spade and then cashing the AK of diamonds, but South was able to ruff the last one, leaving me a trick short. Perhaps North can be squeezed in hearts and diamonds. Anyway, the odds of a 4-0 trump break are less than 10%, far below the odds North or South has five spade tricks to defeat 3NT. 5C will usually tie 3NT when spades are 4-4, but there is a chance they'll lead something else after an uninformative 1D-3NT auction. Next time I get this hand I'll bid it the same way! But six of nine declarers scored 630 or 660 at 3NT, probably on a heart lead.

West opens 1H and North bids 2C or 3C according to taste. Although 3C is an overbid vulnerable vs. not the strong suit reduces the chance of being penalized. Over 2C, East can cue-bid 3C (limit raise or better) and hope to show slam interest below game level. Over 3C East can try 4C or 4NT. It is difficult for East to determine whether 12 tricks are available in notrump, and there is a definite risk of a club ruff at 6H. 4C does not show clear slam interest; it mostly serves to distinguish a power game raise from a more distributional one, where we might not want to double the enemy if they bid to the five level. Another possibility is 3D; this is forcing (so you can support hearts later) and will clue partner in that the King of diamonds is a big card. If he doesn't have it, South is likely to and slam chances will be poor.

West raises to 4D but when East corrects to 4H, it is still not clear East was trying for slam -- in a competitive auction, such a bid may be an attempt to direct the defense (for example, heart lead and diamond switch if the King is not in dummy.) I doubt if a panel of experts would agree on this issue. I don't think it's sound for East to drive to slam on these cards: with 14 hcp outside of clubs opposite partner's assumed 12, a club loser and another seem likely. My partner, however, simply bid 6H, which had an interesting effect -- North assumed he was void in clubs and did not lead her Ace! After a 4NT auction North would probably lead her Ace and, seeing no better chance after dummy appears, continue the suit for down one. 6NT makes from East's hand but seems to require perfect cards.

Seven of nine pairs reached 6H, five going down (presumably on the club ruff), so a cautious +450 was worth 5.5 matchpoints out of nine.
