Petrosian leading in interzonal chess tournament
Portoroz, August 21.
Ten rounds have now been played in the interzonal chess tournament here, and the result is still very open.
Gligoric's prospects of finish among the first five are not now bright as they were. He and Olafsson began well, but in the last few rounds they have been shaken by an unfortunate defeat and seem to have lost confidence.
Some other masters have improved a lot, none more than the youngest one, 15-year-old Bobby Fischer. In the last five rounds he played four grandmasters and one of the best outsiders and score 3½ points — a tremendous feat. Filip and Larsen, however, are in a bad position.
So far Petrosian and Bronstein are still undefeated. Petrosian has had five wins and five draws, but Bronstein only one win and eight draws. Tal and Averbakh are running much faster and playing much better. Matanovic, too, is coming on.
