Deal 20     3NT	♠ Q 7 4 ♥ A Q J 5 ♦ 8 6 2 ♣ K J 4		Play the ♦J. Put yourself in partner's shoes. He almost surely has ♦ K Q 10 x (x). When South holds up on his ♦A, which he almost surely will, West may think he is holding up with ♦ A J x, and be afraid to continue the suit. You can help your partner figure out the true situation by merely playing your ♦J so he can see that South doesn't have it. With this good play West will be able to continue ♦s and defeat the contract.  To Lesson
