Playing a little computer bridge can bring a new problem to light. On this deal, the robot North showed some values with his second bid and tried South’s patience by raising hearts with only three-card support. Rather optimistically, you decided to enquire about key cards and bid a slam. West starts with the ♣K. How will you get to 12 tricks on this deal?

Solution

After winning the ♣A at trick one, declarer counted only nine top tricks and applied the aphorism, “When the contract is in doubt, look to see whether you can set up a side suit.” In this case, the only suit to be considered was spades. As a suit missing six cards is most likely to break 4-2, declarer planned to ruff two spades in dummy.

At trick two, declarer cashed the ♠A and ruffed a spade low. After returning to hand with the A, declarer ruffed a second spade with dummy’s king of trumps, rather than a low card, which would have been overruffed, A club return would have defeated the contract.

In dummy, declarer cashed the K and threw the ♣3 from hand. When all of that had passed off well, declarer drew three rounds of trumps with the ace, queen and jack. Now, East was helpless when declarer cashed the ♠K– he could do no better than ruff this and play a club. Declarer ruffed this with the 4 and his hand was now high, thanks to the two long spades.
