Kibitzer's Corner
Nov-06-06  Rama: The sequence starting with 10. a3 ..., is reminiscent of a variation in the Winawer outlined by Alekhine in his notes to the openings in NY 1924. With 12. Nxc3 ..., white accepts the doubled pawns of the Nimzo, but they are on the b-file, and mobile! Brilliant!

18. Ra3 ..., was the first "grandmaster-move" of the game, that is, one which I did not understand. After 21. Rfa1 ..., I got it. White's b-pawn artificially isolates black's a-pawn, justifying the bombardment by both Rooks.

29. Nxc5 ..., reaps the reward from Ra3 etc. White nets two pieces for a Rook and in about five moves it is all over.

Apr-06-08  Knight13: So 25...Qc5? is a blunder. But Black's position already sucks. I don't blame Spassky for playing 25...Qc5.
Nov-10-08  TheWizardfromHarlem: 18. Ra3 was an efficient move which served a short and long term purpose; it indirectly defends d3 and sets up a nice tactic if black where to try to get one of the bishops with Nd3 ex: 18...Nd3 19. Bxd3 20.Rxd3 20...Nd5 wins the rook(short term). It also as you mentioned prepares a rook battery on the a file .(long term).

In this game Petrosian masterfully shows how to defend every hole in your camp leaving nothing for your opponent to exploit. Very instructive game.

Jun-25-09  zdigyigy: 12. Nxc3! I never would have played this in a million years, but wow did he play it well. And also 24. Ra4! Siezing the only open rank? Shoring up f4 and keeping the pressure up on the rook file.
Jun-26-09  arsen387: absolutely no chances for blacks here, wonderful game by Petrosian

  whiteshark: <Lil Swine: passive yet solid play.> I don't think these attributes characterise the game acceptably.
Sep-17-11  Lil Swine: yeah guess my "thinking was futile" at that time
Feb-21-13  Garech: Very nice game from Petrosian - his duels against Spassky should be more famous!

Apr-18-22  RookFile: Black plays 8...Bb7. How exciting! Beautiful diagonal for the bishop. By a strange coincidence, Petrosian later plays f3 and e4, and that bishop is biting on granite. A lesson well worth keeping in mind.
