Gary Kasparov's reign as world chess champion is assured for another three years. As for the Soviet domination of the game, there is no end in sight.

Even as Kasparov and Anatoly Karpov battled, eliminations were under way to determine the next challenger in 1993. As usual, the Soviets have achieved a disproportionate share of success so far.Preliminary tournaments narrowed the field to 15: seven Soviets, one defector who lives in Switzerland, two others from Eastern Europe (Yugoslavia and Hungary), and just five from the rest of the world (two Britons plus one each from the Netherlands, Germany and India).

With title matches held in three-year cycles, the United States is already out of contention until 1996 at the earliest - but that's hardly unusual.

The Soviets have monopolized the game so completely since World War II that except for American Bobby Fischer's brief reign from 1972 to 1975, no player born in another country has even reached the position of challenger.

Some reasons for Soviet domination: a long tradition in the game; fewer competing attractions than in the West; a society that glorifies chess accomplishments; and government support for training promising players.

Some experts feel that up-and-coming young Soviets, like Boris Gel-fand and Vassily Ivanchuck, may be able to defeat Karpov, 39, in qualifying rounds over the next three years. Both are under 22 and ranked third and fourth in the world, behind Kas-parov and Karpov.

Neither Kasparov nor Karpov is likely to retain more than one-fourth of his winnings after the Soviet state takes its share - "Too much," both men agree.

After the formal winning ceremonies, Kasparov returned to Moscow. He is scheduled to visit the United States at the end of the month to promote chess.
