| Aug-18-07 | | amateur05: After 44. Qd4 the computer evaluation is +2.8 in black's favour (44...e5 45. Qc4 Be6 46. Qe4 Qa7 47. Ra1 Rb8 48. Kg2 Qa5 49. Bf3 Rb1 50. Re1 Rxa1 51. Rxa1 Qxc3 52. Qe1 Qxc2). |

| Oct-17-09 | | Everett: Why does the comp not consider 44.Qxd6? |
|
| Dec-06-09 | | M.D. Wilson: Why did Petrosian take the draw? Surely there's fight left in the position, especially given his nice, comfortable position. |
|
| Dec-06-09 | | Peter Nemenyi: The glib answer would be, "Because he was Petrosian". "Petrosian was obviously unprepared to readjust his frame of mind and start playing for a win"--Fischer wrote that about a game played in 1959, when Petrosian was in his prime. So it's hardly surprising that the older, lazy Petrosian was content to take his half-point with Black without putting any more effort into the game. |
|
| Dec-06-09 | | Lt.Surena: Petrosian was twice the world champion by then. That's a lot more than the coward/racist that put his tail between his legs and ran after 72. |

|
| Dec-21-10 | | Everett: <Petrosian was obviously unprepared to readjust his frame of mind and start playing for a win> This is the biggest difference between Petrosian and Karpov, it seems. |

| Jul-12-14 | | dernier thylacine: In a french chess magazine were written the following lines about the result: "sometimes a sacrifice is necessary in order to avoid family problems".
I just add that this draw permitted to Petrossian and Stein to win together the tournament... |

 | | keypusher: <All the moves are the same, till 5...e6.> All the words are the same, up to "Ishmael." As <dernier thylacine> pointed out seven years ago, Black is totally winning in the final position, but a draw secured a first-place tie for Petrosian and Stein. The 70s were so discouraging that even cheating suffered from lack of effort. |

 | | fredthebear: Most players would take a draw if it assured them of first place, IMHO. Winning the tournament is the objective, not necessarily the game. This "play it safe" approach has been duplicated by many other players. It's the legal form of a plea bargain to get it over with and avoid a lengthy, expensive public trial, a longer sentence. Leonid Stein had defeated virtually all the top players of his era. He was an especially dangerous blitz player. His playing style - master of risk strategy - was much different than Petrosian. Stein was not to be trifled with. There were a handful of draws between these two players prior to this game. Stein died just a few months later at the age of 38. A party in his hotel room seized his heart. |
