Fischer Wins Again, Widens Chess Margin by Robert Byrne
Buenos Aires, Oct. 19—Bobby Fischer ripped through Tigran Petrosian's Sicilian defense for his second straight victory and a two-point lead in their match tonight in the Teatro General San Martin.
Fischer now has 4½ points and needs only two points more to take the 12-game tournament and assure himself of the chance to play Boris Spassky of the Soviet Union for the world chess championship.
The brilliant 28-year-old American, following one of his favorite stratagems, isolated Petrosian's queen's pawn and penetrated on both adjacent files with his rooks. Refusing to be sidetracked by the lure of winning the exchange by 13. B-QN5 PxB, QxR O-O, which would have yielded attacking chances to the wily Soviet grandmaster.
Fischer meticulously tied the enemy forces down to the onerous defense of the weak queen's and queen's rook pawns.
Brings Up His King
By advancing his king at the 28th move, he threatened to grab Petrosian's loose king's rook pawn, thus forcing—P-B4, which meant a horrendous weakening of both the sixth and seventh ranks. Having accomplished that, he at once turned his attention to the queen's pawn, bringing up his king at the 29th move.
The choice facing Petrosian was grim. He knew the pressure would be impossible if the king were to reach the Q4 square. So he advanced his center pawn. That was all Bobby needed. Taking the seventh rank with both rooks, backed up by his powerful bishop raking the white squares, he ended all resistance, quickly setting up the mating net Petrosian found himself in at the 34th move.
Game eight is scheduled for Thursday night.
