3	4	P	5

South trusted that his partner’s values would be outside hearts.

West led the diamond ten. Declarer won with dummy’s jack and ran the spade jack to West’s king. West correctly shifted to a low heart. After ruffing, declarer played a trump to dummy’s queen, getting the news about the 4-0 split, and led the spade five. East won with the ace but then erred. Instead of returning a trump, East tapped declarer with the heart king.

South ruffed and cashed his spade queen (discarding a diamond from the dummy) and diamond ace. Believing East’s high-low in diamonds as showing a doubleton, declarer trumped his last spade with dummy’s club seven, ruffed a heart in his hand, trumped the diamond five with the club queen and claimed the last two tricks with his high trumps. Boyer lost only two spade tricks.

At the other table Moss (West) opened one heart and Plato (East) accurately judged that her hand was worth a game-invitational heart raise. She responded one spade, planning to bid three hearts on the next round. South overcalled two clubs, West made a support double to show three spades, North raised to three clubs, East rebid three hearts, South competed with four clubs, West raised to four hearts, and North doubled.

A trump lead was needed to beat this contract, but North chose the club king.

West ruffed, played a spade to dummy’s (East’s) ace, led a diamond to his king and returned a diamond. North won and shifted to a trump, but declarer won, carefully cashed his spade king, then crossruffed diamonds and clubs to get home.

Plus 600 and plus 790 gave the winners 16 international match points on the board.
