Aug-24-07  patzerboy: Very nice finishing combo set up by 31.b4.

  arsen387: After the great temporary exchange sac black's initiative crumbles and now it's white who's in control of the game. The finishing is also very nice.

Petrosian's wins against purely attacking and very feared in chess world players like Nunn, Kasparov, Tal, Nezhmetdinov and others are almost always very instructive and a pleasure to follow. A great Champion!

Apr-03-09  ForeverYoung: Nunn should have known better than to grab that rook on a1. It is a risky proposition to give up that black squared bishop for that rook. Exemplinary finish by the Tiger!

  An Englishman: Good Evening: Typical Petrosian. Sacrifice the Exchange, then take it right back with the gain of "only" a great square for the Knight and a few "minor" dark square weaknesses. It seems almost impossible to stop him from playing his kind of game--indeed, Fischer had to beat him with it.
Apr-03-09  crwynn: Taking the rook was not an error, it was probably forced. Black's position is bad after 16.b3. I think 15...Bg4 was his last chance to avoid horrible suffering.
Apr-03-09  crwynn: Actually no, even then Black is worse, 16.Qc1 Rb4 17.Rb1 and the awkward rook and b-pawn are just not okay I think.
Apr-03-09  Olavi: What happens after 18...Rxb3?

  arsen387: <Olavi: What happens after 18...Rxb3?> blacks just lose an exchange for a pawn after 19.Nxb3
Apr-10-09  crwynn: 18...Rxb3 19.Be2! 1-0

  arsen387: <crwynn: 18...Rxb3 19.Be2! 1-0> damn, really, that was strong!
May-27-09  ToTheDeath: Actually, 18...Rxb3! 19.Be2 Rd3! 20.Bf3 Qd8 21.Bxa8 Rxd2 etc. is good for Black.

Returning the exchange is the right way to alleviate the pressure on Black's game.
