Fischer's Barren Tactic by Leonard Barden
Petrosian and Fischer took a breather in the fourth game of their world chess championship final eliminator in Buenos Aires. Their draw in 20 moves, the shortest game of the match, followed a well known variation which opening experts have abandoned as sterile for some years.
Petrosian began with the English Opening—P-QR4—but Fischer's defensive formation switched into a variation of the Sicilian Defense. Petrosian's fourteenth move set in train wholesale piece exchanges and when the position simplified into an ending of kings, two bishops, and seven pawns each of the players stopped the clocks and shook hands.
The game, concluded in just more than one hour's play compared with a normal session of five hours, leaves the score in the 12-game series deadlocked at 2-2. The next game is scheduled for tonight.
