U.S. Chess Champion Draws in 4th Round
American chess champion Bobby Fischer of Brooklyn drew with Jan Donner of Holland in the first game to be completed Thursday night in the fourth round of the Piatigorsky Cup chess tournament at the Miramar Hotel in Santa Monica.
The opening was the Marshall variation of the Ruy Lopez, in which black gives up a pawn to obtain a sharp counter attack.
As the game went, Fischer retained the pawn in a strong position. Most of the pieces were exchanged, however, and with opposite-colored bishops on the board, no win was in sight.
The draw was agreed upon after 34 moves.
Draws were also recorded between world chess champion Tigran Petrosian of U.S.S.R. and Borislav Ivkov of Yugoslavia in 25 moves, and between Samuel Reshevsky of Spring Valley, N.Y., and Lajos Portisch, of Hungary, in 16 moves.
Two other games were still being contested at a late hour, between Boris Spassky, U.S.S.R., and Bent Larsen, Denmark, and between Miguel Najdorf, Argentina, and Wolfgang Unzicker, West Germany.
Unfinished games were scheduled to be played off at 11 a.m. today.
The next regular round will start at 1 p.m. Sunday at the Miramar. Paired then will be Portisch vs. Spassky, Ivkov vs. Reshevsky, Donner vs. Petrosian, Unzicker vs. Fischer, and Larsen vs. Najdorf.
