Win the ♠A and plunk down the ♣A. Unless West plays the 9, jack or queen, plunk down the ♣K. If clubs are 3–2, concede a club, if necessary, and you have nine tricks. If someone shows out on the second club, abandon clubs and play for five heart tricks by overtaking the ♥Q and driving out the ♥A.
If the ♣9, jack or queen falls from West at trick two, rather than plunking down the ♣K, lead the ♥Q overtaking if West plays low. If the king wins, lead a club toward your hand, and unless East shows out (not gonna happen), you have a lock for five club tricks by covering whatever club East plays.
When you lead the ♥Q to the king, say East wins and returns a spade, try to run the hearts. If they don’t run, you are still alive for nine tricks if West’s singleton club was an honor by leading a club from dummy and finessing the 10 (if you believe that West started with seven or more major-suit cards. If you believe he had fewer, play for the drop).
