Three of the quarterfinal matches for world championship challengers have been completed in Brussels, Belgium.
Anatoly Karpov of the Soviet Union defeated Viswanathan Anand of India, 4 1/2-3 1/2. Nigel Short of Britain triumphed over Boris Gelfand of the Soviet Union 5-3. Jan Timman of the Netherlands took advantage of lapses by Victor Korchnoi of Switzerland to win 4 1/2-2 1/2.The only match tie after the regulation eight games was between Artur Yusupov and Vasily Ivanchuk of the Soviet Union. This necessitated a pair of tiebreak games at the rate of 60 moves every 15 minutes thereafter.
Yusupov won the first and drew the second to reach the semifinals.
Against Karpov, Anand proved a tough opponent. It was not until the fourth game that Karpov won, and Anand won the sixth. Karpov took the match by winning the eighth game.

- THREE HUNDRED SECONDS - The Utah State Five Min-ute Championship will be held Sept. 21. It will be played at the Sandy Branch of the Salt Lake County Library (10100 S. Petunia Way - 1300 East).
In five-minute chess each player is given five minutes on a chess clock to play the entire game. Any player using more than five minutes for all his moves, loses. With players playing at blitz speeds, it makes a lie of the traditional reputation that chess is a slow and boring game.
Registration will be from 10 a.m. to 10:30 a.m. on Saturday at the library.
The first round will be at 11 a.m., and the tournament is expected to be finished around 3:30 p.m.
Each player will play two games against seven different opponents. There are no eliminations.
Entry fees range from $2.50 to $10, based on age and ability (rating). Trophies will be awarded for both overall places and players in various classes of age and ability.
For additional information telephone Norm Jenson at 486-9628 (work) or 561-2537 (home).
The tournament is being sponsored by the Utah Chess Association. It will be directed by Norm Jenson, A USCF Senior Tournament Director. International Arbiter Robert Tanner will assist.
