East rose with the ace when dummy followed with the deuce but switched to the club four. West scored the king to return the club three as partner won the ace and delivered the club ruff. The game finished down one, N-S -50.
A club shift represented the only chance to set the contract. East led a low club hoping to find partner with a doubleton king and his wish was granted. South should have inserted the jack of spades at trick one to create the impression that West owned the queen. This play should not alter East's line of of thought. A spade return is hopeless since declarer holds a a doubleton and the king of diamonds is onside if South requires a finesse for success. 3NT would be a hazardous contract when East begins with a spade, killing an entry to dummy. North must bring home the heart suit without loss to earn the game bonus. If he plays hearts from the top, all will be well when the queen drops. If West shows out on the ace, North will be booked for a multi-trick set. North was not about to advance to the nine-trick game since there was no guarantee that partner would own the ace and queen of hearts.
