All Fourth Round Cup Games Drawn
All five games were drawn in the fourth round of the Piatigorsky Cup Chess Tournament, being contested through Aug. 15 at the Miramar Hotel in Santa Monica.
This and prior results clearly evidence that the 10 chess grandmasters in the event are excellently matched.
World chess champion Tigran Petrosian of the U.S.S.R. can testify to the hazards he faces daily in this field. He has yet to score a win, losing to Lajos Portisch of Hungary and drawing three games.
Tied for the lead, though barely above the 50% mark, is Bobby Fischer of Brooklyn, 23-year-old U.S. chess champion. He defeated Borislav Ivkov of Yugoslavia and drew three times.
Equaling Fischer's score of 2½ points are Miguel Najdorf of Argentina, Portisch and Boris Spassky of the U.S.S.R.
Most even performances have been recorded by former U.S. chess champion Samuel Reshevsky of Spring Valley, N.Y. and Jan Donner of Holland. Each has drawn all four games for a total of two points each.
Petrosian, with 1½ points, brings up the rear, tied with Ivkov, Bent Larsen of Denmark and Wolfgang Unzicker of West Germany.
The fifth round will start at 1 p.m. today at the Miramar. The pairings are: Portisch vs. Spassky, Ivkov vs. Reshevsky, Donner vs. Petrosian, Unzicker vs. Fischer and Larsen vs. Najdorf. Following are the details of the play last week:
