SEVILLE,SPAIN, DEC. 9 -- World chess champion Gary Kasparov took his final timeout today, postponing the 22nd game of his title contest against challenger Anatoly Karpov until Friday, organizers said.

With just three games remaining, the score is even at 10 1/2 points for each player. Kasparov retains the advantage in the 24-game contest, however, because in the event of a 12-12 tie, he will keep his crown.

Experts said Kasparov will use the break period to prepare his strategy for the 22nd game, in which he will play with the advantage of the white pieces.

Each player may use three timeouts during the 10-week struggle. Karpov has one remaining.

The most likely scenario suggests Karpov will take his last timeout on Monday, postponing the 23rd game, his last outing with white, until Dec. 16, grandmasters said.

In that event, the 24th and final game will be played Dec. 18.

The next world title duel is scheduled for 1990, so the winner in Seville will hold the championship crown for three years.

The victor requires 12 1/2 points or six wins. A win scores one point and a draw a half. Each player has scored three victories with 15 games drawn.
