At the 2005 Fall NABC in Denver, veteran player Ralph Cohen of Memphis showed that he has lost none of his skills as a card player. Watch him in action on this deal from the Bobby Nail Life Master Open Pairs. Cohen was South.
West led the ♣A, followed by a heart switch. East won the ♥A and returned a club. Cohen won the ♣K, played a spade to the ace and a spade to the jack, finding both the good and the bad news.
Going about the business of playing for overtricks (the game was pairs), Cohen played a diamond to the ace, ruffed a low club, played a diamond to the king and ruffed the ♣Q. This was the ending:
Cohen played a heart to dummy’s queen and continued with the ♦Q. East could choose his poison: if he ruffed in immediately, Cohen would overruff, pull the last trump and claim with the good ♥K. If East discarded a heart on the ♦Q, Cohen would ditch his ♥K and play another diamond from dummy. East, down to only his two trumps, would have to ruff and be overruffed one trick later. Plus 450 was good for 19 out of 25 matchpoints.
Note that if Cohen had used the ♥Q as an entry to ruff clubs, South could have pitched his second diamond on the ♣Q and spoiled the coup (actually a grand trump coup because declarer ruffed a winner).
