Tigran V Petrosian vs Robert James Fischer (1958)


Kibitzer's Corner
< Earlier Kibitzing  · PAGE 5 OF 5 ·  Later Kibitzing>
Dec-28-13  offramp: The guy on the left is a Portorozian.
Apr-19-15  Howard: Fischer claimed that 25.Bh5 would have "tied (him) up completely."

Would that have been a forced win ?

Jul-28-15  NeverAgain: The photo for this game is most likely correct. The little of the position on the demonstration board that can be made out against the overhead lamp's glare matches the in-game position after 7. d3.

Further reasons why this could not be a photo from Moscow: a) If this were indeed a casual blitz/training game there wouldn't be signs with players' names at the playing tables, much less flags. b) The most conclusive evidence against the Moscow scenario is the words "a potezi" visible on the demonstration board. It's not Russian or even Cyrillic. It's "and moves" in Serbo-Croatian.

Jul-28-15  RookFile: Such masterful play by Petrosian in this game. Fischer did very well to survive this.
Jul-31-15  Howard: For those of you with engines, would
25.Bh5 had won ?
Aug-08-15  Howard: Just can't help but suspect that Petrosian should have come closer to a win than he actually did.
Aug-11-15  NeverAgain: Howard:
25. Bh5 Ne7 26. Ne3 Kh8 27. Rh4
Kg8 28. a3 a4 29. Rh1 Kh8 30. Be2 Qe8 0.89/35 (Stockfish 6, 171M nodes)

Aug-26-15  Howard: Thanks much, not to mention for your helpful comments regarding Portisch-Huebner, 1979 !
Aug-26-15  NeverAgain: You are welcome.

A few days later I ran the position after 25.Bh5 through Komodo 6, a little longer this time (between 400 and 500mN), and while the proposed lines were slightly different the eval was similar.

The thing all those lines had in common was that both engines sought to redeploy the Bishop to the b1-h7 diagonal ASAP, which leads me to think that 25.Bh5 is a dead end. After Black plays 25...Ne7, which is part of his plan anyway, the Bishop is not doing much on h5.

Sep-27-15  equalizer4: The other player (standing) is the Argentinian Grand Master Hector D. Rossetto. By the way, in 1964 in Havana, Cuba, I played against Rossetto in the giant simultaneous display during the opening of the III Capablanca Memorial International Chess Tournament...Rossetto playing a Ruy Lopez (Spanish Opening)simply crushed me without remorse, lol, my Defense was Closed Morphy. September 27th, 2015.
Apr-25-17  andrea volponi: 57 Rh1 c3 -f5!? c5 -Rc1 Kd4 -f6 Kd3 -g5 Rf8 -Kg4 Kd2 -Rf1 c2 -Kf5 c1=D -Rxc1 Kxc1 -g6 c4 -g7 Rxf6 Kxf6 c3 -g8=D c2 draw.
Jul-26-17  Howard: Does anyone know if there's, say, a PDF file giving corrections/improvements to Fischer's M60MG?

At least 10-12 games in that book--including this one--have had analytical errors exposed over the years, largely due to chess engines.

  whiteshark: <Howard>
There's <Robert Hübner: "Materialien zu Fischers Partien" (roughly <Materials to Fischer's games>, 235 pages, published 2004)>, where he is analysing <the quality of Fischer's M60MG <annotations>> and thereafter classifying its mis-evaluations and mistakes.

I don't know of any English translation.

Aug-30-17  Beancounter: This is game 3 in Fischer's 60 memorables. He called it 'Bear Hug' and comments on Petrosians move 8, "Reckoning he can afford this loss of time in view of Black's misplaced 'KN'."
Aug-30-17  4tmac: 57. Rh7! c6 58. Rd7+ Kc5 59. Rd1 c3 60. f5 Rd8 61. Rc1 Kd4 62. Kf4 Kd3 63. f6 Kd2 64. Ra1 c2 65. g5 Ra8 66. Rg1! Re8 67. f7 Re1 68. Rg2+ Re2 69. Kf3!! Rxg2 & #40 .... but I still think it is a draw (maybe 60..Kb4) What is the "latest" news on this ending??
Aug-30-17  Howard: Charles Sullivan discovered back in about 2009 that the much-heralded 57.Rh7+ would NOT have won after all.
Apr-17-18  dehanne: In his book 51.Kd6 is called a blunder but it completely holds. 54.Kd6 on the other hand is a mistake.
Apr-17-18  Howard: "51.Kd6" ain't legal".
Apr-02-20  FSTIMJP: Cheers.
Anybody knows at which point was this game adjourned? Thanks.
Sep-25-20  vangogh: After Petrosian claimed that 57. Rh7 was the winning move, Fischer analised a variation concluding that should finish in a draw with Petrosian having 2 connected blocked passed pawns. 57. Rh7 c5 58. Rd7+ Ke6 59. Rd1 Rb8 60. g5 c3 61. Rc1 Kf5 62. Rxc3 c4 63. Rxc4 Rb3+ I don't think that this is a draw.
Jan-09-21  Gaito: The strong engine Stockfish NNUE makes a correction of the analysis given by Fischer in "My 60 Memorable Games", page 30. In the position depicted below:

Petrosian played 57. Rh1, and Fischer writes that "according to the Russian bulletins of the tournament, White can win with the following line: 57.Rh7!, etc....". Then he gave a long analysis trying to find improvements for Black (in vain), and his conclusion was that White wins. Nevertheless, the ending is drawn, and there is no way for White to win, no matter what the Russian bulletins of the tournament might have to say. The engine proves that the position is a draw: From the diagram: 57.Rh7! c5! 58.Rd7+ Ke6 59.Rd1 Rb8 60.f5+, reaching the following diagram:

Instead of 60...Ke5 (given by Fischer as best), the engine gives the line 60...Kf6! 61.Kf4 c3 62.g5+ Kg7 63.Rd7+ Kf8 64.Rd1 Rb4+ 65.Ke5 c4 66.Rc1 Rb3 67.Kf4 Kg7. In this position:

the computer proves that it is a dead draw.

  Sally Simpson: This with the 'bad etiquette.' comment had me thinking back in the old days you had to show you knew the draw. (play it out).

Only later did I discover it was bad etiquette to offer a draw when it's your opponents move. I wonder why Bobby never knew that. Possibly not in the habit of offering draws.

Apr-21-22  Granny O Doul: ...Bad etiquette to offer on your own move. But also pointless, as the opponent can say "show me your move", and by then you may have found a winning move.

I was never sure, reading the book, that the reference was to its being Black's turn to move, or to the fact that Black was the one who had to prove the draw. I suspect the note was Evans's insertion to show that Bobby had learned a thing or two about etiquette in the years intervening.

  perfidious: Annotating L Day vs Adorjan, 1981 in <Chess Canada>, I recall White mentioning that Adorjan proposed a draw while on move; Day retorted, 'make a move' and his opponent came up with a lemon.

  Sally Simpson: Hi Granny,

'Evans's insertion...'

You may be right but I think this is Bobby recalling the moment. Reads like he may have been pulled up about it after the game.
