This week's deals have treated declarer's technique of entry management. To see what you've learned, cover today's East-West cards. Against your five clubs, West leads the king of spades and then another spade. How do you proceed?
The actual declarer ruffed the second spade, drew trumps, cashed the A-K of diamonds and ruffed a diamond. When West discarded, South tried the A-K of hearts and a third heart, hoping for a 3-3 break. Instead, West got two hearts to defeat the game.
South played as if the contract were six clubs. (Then he would need a 3-3 diamond break for two heart discards.) At five clubs, South must set up and cash the fifth diamond, but in case of a 4-2 break, he needs one additional entry to dummy. After South draws trumps, he leads a diamond and plays low from dummy.
If East wins and shifts to a heart, South wins in his hand, takes the A-K of diamonds and ruffs a diamond. He gets back to dummy with the ace of hearts to cash the good diamond.
You hold: 5 T K 7 5 2 8 2 A K Q J 9 4. Your partner opens one diamond, you bid two clubs, he rebids two diamonds and you try two hearts. Partner next bids two spades. What do you say?
A: Partner appears to have five or six diamonds and four spades, though he might have a hand with spade strength but doubts about no trump. (He might hold A 6 2, A 3, K Q 10 7 4 3, 7 6.) Since your first two bids created a force, you need not pick a contract yet. Bid three clubs.
