Chess Champs Still Tied
Moscow (UPI) — Soviet grandmasters Viktor Korchnoi and Tigran Petrosian, unable to crack each other's defense, agreed to their eighth draw Monday in a semifinals world chess championship match, the news agency Tass said.
Korchnoi studies his 16th move for 20 minutes before proposing a draw. Petrosyan agreed, making the score in the 10-game series 4-4.
The tedious series of draws was in contrast with the victories of America's Bobby Fischer, who a few hours earlier scored his fifth win over Denmark's Bent Larsen in Denver. Fischer needs only one-half point to win that semifinals match, and currently leads 5-0.
The winners of the Denver and Moscow matches will meet later this year to decide who will get a chance to play world champion Boris Spassky in 1972.
The world chess title is decided every three years.
