Moscow — (UPI) — Tigran Petrosian upset world champion Boris Spassky in the sixth round of the Alekhine International Chess Tournament Tuesday night, the news agency Tass said. Both men are Russians.
Petrosian, playing white, won on the 40th move when Spassky admitted defeat. Spassky played a conventional queen's gambit, Tass said.
Petrosian lost to Bobby Fischer of the United States in the world chess semifinal in Buenos Aires last month. Fischer and Spassky meet for the world title next year. Go Bobby!
