| Aug-24-08 | | eisenherz: A game with some blunders.
The first one being 23... ♗e8 by black. As pointed out by whiteshark 23... ♕e8 is much stronger with the following possible continuation: 24. h5 ♗b2 25. ♗g5 ♖e6 26. ♖c2 ♗e5 27. hxg6 ♗xg6  Δ 28... f4.

| Aug-24-08 | | eisenherz: The second blunder being 24.c5 by white.
Better would be: 24.♕xa7 ♗f6 (24... ♗c6 25. ♗xc6 bxc6 26.♗xd6  ) 25.♗xb7 Dd7

| Aug-24-08 | | eisenherz: after 24.c5 the best answer for black is 24... b6 Δ 25... dxc5 The game than evolves from a position at move 25 to a  position at move 34. Black should have than played 34... ♗a6 Δ 35...b6 or play the move suggested by whiteshark 36...Ba6 with the same idea, what would still hold the black position. By damaging its pawn structre with c-double pawns and allowing white a passed a-pawn, black sealed its fate in the endgame. |

| Aug-27-08 | | eisenherz: Sorry, at my first comment I meant 23... ♕b8 as <whiteshark> wrote. |

25 ... c7x♗d6 26 c5xd6 <discovered attack>
click for larger viewPetrosian's 25 ♗f4-d6! is an *excellent* example of the <FILE OPENING PAWN TRICK>, exploiting the alignment of pieces White c1-rook + White c5-pawn + Black c7-pawn + Black c8-rook. <PizzatheHut: 25. Bd6! A nice example illustrating Petrosian's excellent tactical ability.> Indeed. |
|
| Dec-26-10 | | pericles of athens: i'm as impressed with Bd6! as you guys are. never would have found this line myself. fritz gives the position as +2.8. would make a nice puzzle of the day, eh fellas? |
|
| Dec-27-10 | | AnalyzeThis: Practically speaking, Botvinnik's mistake was to leave his queen on the same file as the rook, which made a tactic like Bd6 possible. |
|
| Dec-27-10 | | sevenseaman: Petrosian, the positional master; here at the 25th the contortionist is the subtle extortionist, taking bits off the pie! |
|
| Mar-15-11 | | k009ris: Hile all!
Its all well said indeed , I just add one more comment : why take on d5 after winning the exchange and allow some counterplay with.f4?
Simply 27.e3 and then advance on Q-side.
Black has to lose a pawn anyway.

| Apr-05-11 | | soothsayer8: 36...Bc6 seems like such a bad move to me, why would black allow white to double his pawns like that? It became such a liability. I especially liked how white was able to use the doubled pawns as a blockade for his own purposes. |

 | | Domdaniel: Black's first small mistake - the kind of positional autopilot move that no engine is really able to grasp - is the 'obvious' recapture 8...Nxc6. There are at least 50 games in the database with the position after 8...bxc6, but this is the only example of the Knight recapture. By accepting doubled pawns with ...bxc6 Black gets rapid counterplay on the b-file and good squares for his pieces. The line in the game is a bit too passive, ceding d5 to White. |
|
| Aug-27-11 | | positionalgenius: Excellent game. Petrosian was a one of a kind player |
|
| Jul-17-12 | | Ulhumbrus: 6...d6 avoids conceding an advantage in space to White. Botvinnik has said thst he was nervous during the week following an incident during the fifth game of the match and that may explain the move 6..exd4 |
|
| Jan-12-15 | | thegoodanarchist: Petrosian, famous for sacrificing the (his) exchange, here sacrifices his opponents' exchange, on move 25. |
|
| Mar-02-15 | | kevin86: Does the bishop in the "Great Snake" have the same serpentine qualities as the DRAGON bishop in the Sicilian? |
|
| Nov-05-16 | | huturowa: Botvinnik: When Tal sacrifices a piece, take it, when Petrosian sacrifices a piece don´t take it. |

 | | perfidious: <huturowa: Botvinnik: When Tal sacrifices a piece, take it, when Petrosian sacrifices a piece don´t take it.> Bridge great Terence Reese and co-author Albert Dormer attributed Botvinnik thus: <If Tal offers you a pawn, take it.If Petrosian offers you a pawn, decline it.
If I offer you a pawn, think it over.> |
|
| Feb-25-18 | | tgyuid: for me, easily botvinniks weirdest game; 3...e5 blocks your own diagonal for example.... |
|
| Feb-25-18 | | tgyuid: 36...b6; the text is surely capitulation |
|
| Feb-25-18 | | tgyuid: 17...Bg8; why |
|
| Feb-25-18 | | tgyuid: ...a5, Ne5, and c6 is in the game, i say |

 | | sakredkow: <euripides: Interesting how Petrosian simpply vacates the long black diagonal here. Similarly, in Petrosian vs Gufeld, 1960, he plays around the c1 square that his opponent is attacking -an idea that Gufeld praises very highly in his notes.> That's really great advice to remember. I get a little panicky looking down an opponent's strong fianchettoed B. Don't panic - vacate! It might make a good chapter in a strategy book. |

 | | kingscrusher: The opening position for black after move 8 seems clearly in White's favour to me with nice control over d5. Perhaps the engine suggestion of 8...dxc6 is worthy of practical investigation: 23: Tigran Vartanovich Petrosian - Mikhail Botvinnik 1-0 7.0, Botvinnik - Petrosian World Championship 1963
click for larger viewAnalysis by Stockfish 14:
1. = (-0.13): 9.Qxd8 Rxd8 10.Bg5 Re8 11.0-0-0 Be6 12.e4 h6 13.Be3 Bxc4 14.Rd7 Be5 15.Bxh6 Bd6 16.Bh3 Nc8 17.b3 Ba6 18.Bf4 Nb6 19.Rxc7 Bxc7 20.Bxc7 Bd3 21.f3 f5 22.Re1 It seems in practice according to Chessbase, that most players are playing bxc6 (189 games compared to 2 games for dxc6) Maybe players don't want the queens off with black but the doubled pawns stop d5 being such a painful square to look at. |

 | | plang: 8 Nf3 had been played in the short draw Olafsson-Geller 1962 Stockholm Interzonal; 8 Nxc6 was new. Several commentators recommended 8..bxc as a more dynamic choice giving Black more play in the center as well as an open b-file. 16..Qf7 followed by ..Bc8 was suggested as a better way of defending the queenside. 18 Qa5..Ne6 19 Qxa7..Ra8 20 Qxb7..Rfb8 21 Nb6..Qf7 22 Qxa8..Rxa8 23 Nxa8..f4 would have given Black sufficient counterplay. The older I get the more I appreciate Petrosian - this was a really nice game. |
