LONDON (AP) — Champion Garry Kasparov and challenger Nigel Short both had much to regret in Game 1 of their breakaway world championshipmatch.Kasparov admitted missing chances to win on the chessboard Tuesday, while Short was beaten by the clock failing to make 40 moves within two hours as required.It was a bitter way to lose, and an unhappy wayto win.“1 definitely wanted to win the game and not have Mr. Short lose on time, Kasparov told reporters.In a world championship match, anything can happen. If Nigel would have had enough time, I would have forced a draw.”Short is a notoriously bad starter, having come from behind in his previous five qualifying events, and his advisers are likely to urge him not to force the pace in Game 2 on Thursday.Kasparov is used to starting well, and will be disappointed that he did not impose himself convincingly while having the advantage of playing the white pieces.Kasparov put on pressure at the end and Short panicked, but he wasn’t outplayed,” said American grandmaster Larry Evans, a five-time U.S. champion.The furious finish — Kasparov had five minutes and Short two to make their last 10 moves — made both players victims of their innovative rules.After Short won the right to challenge Kasparov for the world championship, the two players reject ed arrangements proposed by the World Chess Federation and formed a breakaway organization, the Professional Chess Association.Their aim was to make chess more attractive to the public and thus more lucrative. Besides speeding up the clock, their rules force players to stick to a three-games-per-week schedule with no timeouts, and to play 24 games even if one player has won the match.While Short ultimately cracked. Kasparov took unnecessary risks and conceded making mistakes.Analysts were surprised by Kasparov's eighth move. Grandmaster Jon Speelman, Shorts second, called it wimpish.” Kasparov chose a defensive move designed to avoid the Marshall gambit, in which black sacrifices a pawn to go on the attack.
