Tense Chess Match
Buenos Aires, Saturday, (AAP).— U.S. chess ace Bobby Fischer (pictured) and former world champion Tigran Petrosian of the Soviet Union go into the sixth game of their match here tomorrow tied with 2½ points each.
Yesterday's fifth game of the series to decide a challenger for the world championship ended in a draw, the third of the series.
The victor — the first player to get 6½ points — will meet Boris Spassky of the Soviet Union in April and May next year.
Petrosian varied by using the Petroff defense after Fischer's almost inevitable 1. P-K4 yesterday. The opening is rare seen in modern grandmaster practice, though well suited to Petrosian's defensive style.
Fischer played more forcefully in the opening, building up a strong center, with more mobility for his pieces.
Instead of directly challenging the center, Petrosian advanced his queen side pawns, with the objective of opening lines for his men in that area.
Petrosian offered a draw on his 34th move. Fischer refused, but four moves later, seeing no winning prospects, he offered a draw in turn, which Petrosian immediately accepted.
