Your next move is to establish the club suit. You should play the ♣Q from dummy, to ensure that you lose the lead to East, who cannot play spades safely. East wins the king and plays back a club which you win with the ♣A. You ruff a club with the ♥8, establishing the suit. The stage is now set for the big play. You cash the king and ten of hearts, and play the carefully preserved ♥3 to endplay East, who will be forced to play a spade away from his king.

When this deal was played, tricks one through four were identical to the recommended play. At trick five, the declarer cashed the ♥J, but failed to underplay the three. He then played a low club from the table; East naturally went up with the king and played a club to dummy's queen. When the ♣A was played next, East could have defeated the contract by ruffing with the ♥9. When East ruffed with the ♥7, declarer recovered from his earlier lapse by overruffing with the ♥10, and exiting with the ♥8 to East's nine. East had to play a spade away from the king; apart from securing an extra spade trick, the endplay enabled declarer to reach dummy via the ♠Q, and cash the established clubs.
