Jan Wohlin of Sweden specializes in composing problems for both the amateur and the expert. Here’s one that should prove interesting regardless of where you rank as a player.
Assume you’re in six hearts and West leads the king of diamonds followed by a spade to dummy’s king. You ruff a diamond at trick three, and East discards a spade. How would you continue?
Even if you don’t look at the East-West hands, you already know from the bidding that you can’t make the slam by ruffing a spade in dummy. You also know, after East’s discard at trick three, that West started with five diamonds headed by the A-K, which means dummy’s diamonds can’t be established.
Nevertheless, the contract can be made by developing a squeeze against West. After ruffing the diamond, you draw four rounds of trumps and cash the A-Q of clubs, producing this position:
When you now lead the ten of clubs to dummy’s king, West has no answer. If he discards a spade, you cash the ace of spades and take the last two tricks with the heart ten and spade nine; if he discards a diamond, you ruff the jack of diamonds and score the last two tricks with the spade ace and diamond queen.
