SEVILLE, Spain — The 21st game of the world chess championship between titleholder Gary Kasparov and challenger Anatoly Karpov ended as a draw in a complex position after 28 moves on Monday.
The result kept the scores tied at 10 1/2 points in the 24-game match, with three wins and 15 draws for each of the Soviet players.
Kasparov, 24, has the advantage of retaining the crown in the event of a 12-12 deadlock.
The 36-year-old Karpov, playing white, considered his rival's offer to split the point for more than 10 minutes before finally accepting.
A win counts one point and a draw half a point.
Chess experts were puzzled by Kasparov's decision to try to force a draw by a perpetual repetition of moves. If the same position occurs three times with the same person to move, the game may be claimed drawn.
