Slam Auctions (10) by David

A: 4NT. Madala held a great hand, and his singleton heart controlled the suit indicated by the opponents. He chose to bid Roman Keycard Blackwood.

Duboin responded 5♠, showing two keycards and the ♠Q. Before you move to the next question on the same deal, decide how you would have continued.

Your result so far:

A: 7♠. Madala decided he had heard enough to venture a grand slam.
His partner held:
♠ K Q J 8 6 4 2
♥ A 9 8
♦
♣ K 7 3

As you can see, there were 12 tricks on top . A heart ruff in the short-trump hand brought the total to 13. The grand slam was also bid by USA2.

Your result so far:

A: 5♣. When Brogeland jumped to 4♠, Bakke could see the chance of a slam. He might have bid RKCB, but he preferred to cue-bid clubs. When his partner cue-bid 5♦, he jumped to 6♠.

Partner's hand was:
♠ J 7 4 2
♥ K
♦ A Q 7 4 2
♣ 8 3 2

Trumps were 2-2 and diamonds 4-1. Both tables made 6♠ with an overtrick.

Your result so far:

A: 4♦. The bidding is forcing to game, so 3♠ does not limit partner's hand. Weinstein made a cue-bid (control-bid) of 4♦ to show the ace or king of diamonds. This was enough for partner to bid 4NT.

Your response of 5♣ showed 1 (or 4) keycard. Partner then knew that a keycard was missing and he leapt to 6♠.

If you had held the ♦A instead of the king, and showed two keycards, the contract would have been 7♠.

Your result so far:

A: 5♦. Since his partner might hold only seven hearts, Drijver decided to ask for the ♥Q (that is what 5♦ normally means). His partner had eight trumps, plus a void and a side-suit king. He therefore leapt to 6♥.

Brink held:
♠
♥ K J 10 9 7 6 5 4
♦ 10 8
♣ K 10 8

13 tricks were made. At the other table, Weinstein and Levin began with the same 4♥ - 4NT - 5♣ - 5♦ bids. When 5♦ was doubled, followed by two passes, Weinstein redoubled, but passed his partner's 5♥.

Your result so far:
