ViW ■ ■ ■ ■AW7h*hmh*bChir#mt?By Kevin Burnett-National MasterMemorial ImpressionsThey called it “the biggest tournament west of the Mississippi,” and the organizers of last weekend’s Memorial Day Classic weren’t just whistling Dixie. 491 players turned out for the three-day event at the Sheraton-Universal Hotel. The top prize was shared by four of California’s finest international stars, Grandmasters Larry Christiansen and Walter Browne and International Masters Jack Peters and Nick deFirmian (all with totals).The rest of the good (and the lucky) competitors who partook of the $23,000 prize fund are too numerous to name here. Instead, your humble correspondent (who did not partake) would like to offer hearty congratulations to the prize-winners and their bank accounts and proceed to relate some of the incidents and sensations that made the tournament a memorable one.The first and foremost sensation was the play of high-schooler Karl Yee. The tournament hall buzzed with excitement in the second round as he demolished GM James Tarjan in just 26 moves. Yee went on to clobber two more strong masters with his fierce attacking play before faltering in the later rounds. Round two saw another upset when Senior Master David Strauss lost on time in a winning position to Expert Mario Spinosa.Veteran Expert Sid Rubin had a good tournament as well, knocking off Senior Master Victor Frias and taking GM Peter Biyiasis to the very limit before losing in long and complicated endgame.Indeed, this was quite a tournament for exciting endgames. Co-winner Christiansen, for one, played a pair of dazzling endgames against Ivars Dahlberg and William Batchelder. Thus inspired, in the very next round, Batch-elder miraculously turned a probable loss into a win with some fighting endgame play. But the most talked-about finale of all was an eight-hour, fifth-round marathon which had held up the last-round pairings for an hour and a half. When the tournament director could wait no more, he looked at the position and saw (correctly) that Black had • an easy win. So he made and announced the pairings. Fifteen minutes later, to his horror and to the groans of hundreds of players, Black lost his mental bearings just four moves from victory and gave White a draw. This necessitated new pairihgs and, though the directors scrambled like veteran short-order cooks, a further half-hour was lost.Before we leave this exciting tournament behind us, let’s mention just one more sensation, albeit an aborted one. Fearless attacker Robert Hurdle of Los Angele was at his fearless best in his fifth-round donnybrook against eventual co-winner Browne. He had Browne on the ropes and then’ made a slight and seemingly innocuous move-order mistake that turned a potential brilliancy into a frustrating defeat. And the chess gods above intoned something about “the thrill of victory and the agony of defeat. ” Wait ’til next year.Book ReviewEncyclopedia of Chess Middlegames: Krogius Livschitz et. al.; Chess Informant; 351 pp.; $25.To quote one old master: “Chess is 99% tactics.
