Adam Kaplan's Play at the Bermuda Regional The winner of last year's American Contract Bridge League youth master point race for players under 20 was Adam Kaplan of New Port Richey, Fla. He had 931.03 points, ahead of Zachary Grossack of Boston (545.81), and his older brother, Adam Grossack of Boston (463.90). Kaplan, who was 16 last month, defended well in the diagramed deal from the Bermuda Regional in January, where he won more master points than anyone else. At the other table three no-trump was bid and made. In the given auction, after East passed and South opened one club, Kaplan (West) chose to overcall in his strong four-card major. He thought his hand was too light for a takeout double, and if he was going to make only one bid, he preferred to name his strongest suit. Also, if partner, Robert Todd of Tallahassee, Fla., had the heart ace, the opponents would never get to three no-trump, thinking they would immediately lose five heart tricks. The rest of the auction was natural, with three hearts by East being pre-emptive and promising at least four-card support. With a maximum pass and heart support he would have cue-bid three clubs. Against three no-trump West led the heart king, and East discouraged with his nine (upside-down signals). When South ducked, West continued with the heart queen, and East played his eight, using standard remaining count to show that he had an even number at that point. West now knew that East had started with five hearts. Declarer won perforce, played a spade to dummy's queen and led the club queen, which was covered by the king, ace and ten. At this point the Principle of Restricted Choice suggested that West was more likely to have a singleton ten than a doubleton ten-nine, because with that holding he might have played the nine; with the singleton ten his choice was restricted. If South had crossed to dummy's diamond ace and played a club to his eight, he would have won two overtricks. But he chose to cash the club jack and lead another club. On these tricks Kaplan discarded his remaining hearts, so that East could cash his three hearts to defeat the contract. Plus 600 and plus 100 gave Kaplan, Todd and their teammates - Patricia Herlihy of New York City; Theresa Andino of Niceville, Fla.; and Adam Parrish of Arlington, Mass. - 12 international match points on the board en route to victory in the Flight A Knockout Teams. Did you notice that South could have made his contract after taking the club jack because of the lucky diamond position? He would had to cash the ace and king of spades, the second of which would have forced East to discard a diamond. If East threw a heart, declarer could establish clubs. On the next spade to West's ten, East would probably discard a heart. West would cash his last heart, then lead a low diamond. But South would take East's jack with his king and could lead back the ten to pin East's nine. He would take three spades, one heart, three diamonds and two clubs. Monday's column gave the wrong start date for the Houston Lone Star Regional. It was Jan. 30, not Jan. 20. Also, the column omitted two steps in how Eric Rodwell handled the heart suit in his contract of three no-trump. The correct play is online at nytimes.com/crosswords.
