|Jul-27-05|| ||ARTIN: Petrosian considered this to be one of his best games. Rxf4 followed by Bxf4 is better but the position after that is quite unclear according to Petrosian.|
|Nov-19-06|| ||Open Defence: only 2 kibitzes for this game.....|
|Nov-19-06|| ||jamesmaskell: Great move there by Petrosian...Rf4. Tal just couldnt deal with it. Shows a high level of depth in Petrosians chess. Whilst aggressive attacking chess is the naturally attractive chess we all enjoy, seeing a player play slow and let the opponent lull themselves into a false sense of security, then pulling a move like that which throws their position apart is beautiful.|
|Nov-19-06|| ||OneArmedScissor: Excellent game!|
|May-26-08|| ||apexin: indeed. it goes into my collection.|
|Jun-07-10|| ||shakespeare: nice vid on youtube
|Jun-07-10|| ||waustad: Petrosian had so many exchange sacs. As happened so often, it was to get a monster knight outpost.|
|Apr-16-15|| ||Howard: Kasparov states in his book MGP that Petrosian missed a win that involved
"higher chess geometry", but I don't recall where it was.|
|Apr-16-15|| ||RookFile: Terrific defense by Tal.|
|Apr-16-15|| ||Petrosianic: I don't have a board to check it out now, but maybe he meant 72...Ke7 instead of Kf7? Trying to gain distant opposition?|
At the end, Black can only win by outflanking White's King and capturing the h pawn outright (because exchanging clearly doesn't work).
If 72...Ke7 73. Kf5 Kf7 74. Kg4 Ke6! 75. Kf4 Kf6 76. Kg4 Ke5 77. Kg3 Kf5 78. Kh4 Kf4 79. Kh3 Kg5 winning.
But I'm probably missing something obvious, as Kf7 seems too obvious to miss, unless Black's flag were tottering, or unless it just doesn't work.
|Apr-18-15|| ||Howard: No, Petrosianic, the moment that I've referring to occurred somewhat earlier in the game.|
I'll check it out when I get home. Right now, I'm at the public library.
|Apr-18-15|| ||Retireborn: Don't have Kasparov's book, but Houdini identifies the missed win as 48...Rb5! (instead of 48...Ra8) 49.Qa4 Qh4+!|
The variations that follow are true computer stuff and not easy to understand, but essentially Black gets to keep his b-pawn whilst hammering the white king.
In the game the b-pawn gets exchanged off and after 50...Re5 Black's extra pawn isn't worth much.
|Apr-20-15|| ||Howard: Just checked Kasparov's book last night, Retireborn, and you're "half right."|
Yes, 48...Rb5! would have won, as both you and the book point out.
But MGP also points out that 60...Qe3+ would have won, too. That's where the "higher computer geometry" comment comes in.
|Apr-20-15|| ||Retireborn: Interesting. Yes, 60...Qe3+ 61.Kh1(h2)Ra4! and Black wins another pawn, since 62.Qxf5 Rh4+ will win the queen|
That means that 60.Qd5 is a blunder and should be replaced with 60.Qb7 - then 60...Qe3+ 61.Kh1 Ra4 achieves nothing as White has 62.Qc8+ & 63.Qxf5 with check (and in fact perpetual check) which makes all the difference.
|Apr-20-15|| ||Petrosianic: <Howard>: <No, Petrosianic, the moment that I've referring to occurred somewhat earlier in the game.>|
It must have. I just got a board out to check it, and forget what I said before. It's all hallucination. 72...Ke7 73. Kf5 Kf7 74. Ke5, and White is just fine.
|Apr-21-15|| ||Howard: No problem---we all make those mistakes, especially yours truly.|

|Jul-23-17|| ||Johnnysaysthankyou: Correct is the astonishing 31. h7!!. Where after 31...Rxf6 32. Rf6 g6 33. Rd1, black is in some kind of zugzuang hell. I doubt Tal would have seen this move at this point in his career but damn if he had played it...|

31 ... Rxf3 (white's queen) seems a reasonable alternative. What did you have in mind?
|Sep-02-17|| ||beatgiant: <Johnnysaysthankyou>|
31. h6 Rxf3 32. Rxf3 g6 33. Rd1 <f5> and I don't see any <zugzwang hell>. Black can soon push his kingside pawns to f4 and g4, White's h-pawn will fall, and all Black's pieces will swarm over the kingside and win more material in the foreseeable future.

|Dec-29-19|| ||Honza Cervenka: Another missed winning opportunity by black is 46...Rd8!|
On the other hand, white could hold some advantage playing 37.b3! Bb8 38.d6 Nc6 39.Rad1 Nd4 40.Kh1 Nxb3 41.Rd5 etc.
