Merrimac Answer:


South wins the club and tries 2 diamonds, East must duck.  Now 3 rounds of clubs, 2 hearts and exit with the Jack and West is end played.

West can cash 2 hearts, but must give declarer the last 2 tricks in spades.  Declarer scored 2 spades, 2 Hearts, 2 Diamonds and 3 Clubs for 9 tricks.
