An 8-Hour Chess Battle To a Draw
SANTA MONICA — (AP) — A spectacular, tense duel in the fourth round of the Piatigorsky Cup international chess tournament ended after eight hours of play with Russia's Boris Spassky tying with Denmark's Bent Larsen.
The draw, giving each a half point, kept the Russian in a four-way tie yesterday for first place with Bobby Fischer of the United States. Miguel Najdorf of Argentina, and Lajos Portisch of Hungary.
Each has 2½ games to his credit against 1½ in the loss column.
Larsen—who occupied a rather poor position through the first 40 moves of the long game—ended up with a one-pawn advantage over Spassky after five hours.
Two more sessions failed to produce a winner, so the match was called a draw. Other standings are: America's Samuel Reshevsky and Jan Donner of Holland, 2-2; world chess champ Tigran Petrosian of Russia, Borislav lvkov of Yugoslavia. Wolfgang Unzicker of West Germany and Larsen, 1½-2½.
Pairings for the fifth round tomorrow are Portish-Spassky, Ivkov-Reshevsky, Donner-Petrosian, Unzicker-Fischer and Larsen-Najdorf.
