South grabbed the ace, unblocked the king of clubs and led a spade to the king. A heart was parked on the club ace but South was confronted with a decision. He could settle for twelve tricks by ruffing a diamond in hand to draw trump conceding only a heart. However, this line gives up a chance of winning thirteen tricks. He elected to play a third club in the hope of bringing down the queen. When East contributed the seven, should he ruff with the ten or a top spade? He chose to play the spade ten but West overruffed and cashed a heart restricting him to eleven tricks. This line would have succeeded when clubs broke 33 or when West did not own the jack of spades. At matchpoints, it was quite reasonable to attempt to win thirteen tricks although the result was disappointing. If N-S had reached a spade slam, declarer would undoubtedly play in a fashion to guarantee success. He would follow at trick five with ace and a diamond ruff to draw trump, conceding only a heart trick. Many pairs would not reach slam on this deal where it would be important to guarantee the slam bonus. Should North have invited slam by advancing to five spades in search of a heart control?
