Chess History: The Fischer - Petrosian Match of 1971

Chess History: The Fischer - Petrosian Match of 1971

---------------------------------------

I've read a lot of experts thought that Petrosian had built up winning advantages in the first 5 games of their 1971 match, but let Fischer off the hook.

That observation is supported by annotations from top Soviet grandmasters (including Yuri Averbakh, Viktor Korchnoi, and Garry Kasparov).

The narrative that "Fischer blew Petrosian away 6.5–2.5" leaves out how close Petrosian came to putting Fischer in a severe psychological and scoreboard hole during those opening five games. Petrosian routinely outplayed Fischer in the openings and early middlegames, but missed the killer blows.

Game-by-Game Breakdown of the First 5 Games

• Game 1 (Fischer 1–0 Petrosian):

  Petrosian introduced a powerful theoretical novelty on move 11 (11...d5) in the Sicilian Defense. He seized the initiative and reached a winning dynamic position, but under early time pressure he missed the tactical stroke 16...Rxg2!, which would have blown open Fischer’s kingside. He let Fischer back into the game, eventually blundered in time trouble, and lost.

  • Verdict: Petrosian missed a clear winning shot.

• Game 2 (Petrosian 1–0 Fischer):

  Petrosian dismantled Fischer’s Grünfeld Defense with a prepared variation (8.Ne2). He dominated the board and scored a clean, decisive win, snapping Fischer's legendary 20-game winning streak.

  • Verdict: A Petrosian masterpiece.

• Game 3 (Fischer ½–½ Petrosian):

  Petrosian played his signature French Defense and completely out-maneuvered Fischer in a complex middlegame. Fischer was on the brink of a second consecutive loss, but as the time control approached, Petrosian hesitated to press his advantage and allowed Fischer to escape with a draw by repetition.

  • Verdict: Fischer was completely on the ropes; Petrosian let him off the hook.

• Game 4 (Petrosian ½–½ Petrosian):

  This was the only quiet game of the opening stretch. After three intense battles where Fischer was physically and psychologically rattled, Petrosian had White and an opportunity to keep the pressure on. Instead, he chose a safety-first variation and offered a quick 20-move draw. Many Soviet analysts later criticized this decision, arguing Petrosian gave Fischer much-needed breathing room when he should have pressed his momentum.

  • Verdict: A missed psychological opportunity.

• Game 5 (Fischer ½–½ Petrosian):

  Petrosian rolled out the Petroff Defense. Fischer tried to force play, but overextended, allowing Petrosian to seize control of the middlegame. Once again, Petrosian couldn't find the most precise continuation to convert his spatial and positional initiative, and the game simplified into a drawn endgame.

  • Verdict: Petrosian stood better, but settled for a draw.

The Psychological Shift

Heading into Game 6, the match was tied 2.5–2.5. By all accounts, Petrosian had been the better player over the board in terms of positional creation, but the scoreboard did not reflect it.

Failing to score 3.5 or 4 points out of those first 5 games took an immense physical and psychological toll on Petrosian. His second, GM Yuri Averbakh, later noted that the extreme tension of letting those chances slip—combined with Fischer's relentless, grinding stamina—caused Petrosian to mentally collapse starting in Game 6. Fischer then won four games in a row to close out the match.
