| Oct-27-06 | | kevin86: Black is in heavy Zugzwang. He can do nothing but move the rook up and down the a file. White captures the two black pawns and then ushers home the f pawn. Black has no hope even for a stalemate trap. The king may not move without allowing the rook to check with promotion to follow. The rook may not leave the a file of else white SACS the rook at a8 to promote with check. If black tries to impede the white king,the latter simply temporizes and the rook must move to let him pass. |
|
| Oct-27-06 | | Billy Ray Valentine: Kevin86: Am I correct that after White captures both black's pawns he can simply plant his king on e7 and march his f pawn all the way to promotion? Since black's rook has to stay on the a-file and black's king can't move. If blacks rook starts checking the white king on e7, the king can make its way to the queenside until black has no more checks. |

| Jul-28-07 | | talisman: ball game tied and it's getting late.petrosian repeats the line from his game one victory.spassky had to be waiting and hoping for this. |
|
| Apr-06-08 | | Knight13: In the final position, if the f-pawn were instead the g or h pawn, or on any square from b-e the game would've been a draw. Wait nvm that pawn on h6 makes all the difference Black can't capture it. |
|
| Jul-01-09 | | WhiteRook48: and even if Black had a stalemate trap Spassky wouldn't fall for it |

|
| Jun-08-11 | | thejack: Petrosian tried the same obscure opening line against Fischer two years later. Fischer opted for 8.c4 - and scored a famous victory. |
|
| Jan-28-14 | | Ulhumbrus: Does Black need to concede the d file to White by 21...Rf5? Instead of 21...Rf5, 21...a4 undermines White's N on c4 but then 22 Rxd5 Nxd5 23 Qg4 defends the N on c4 with tempo, making after eg 23...Bf8 24 b4 possible. This suggests 21....Rad8 |

 | | offramp: Before this game the score in the match was 3-3. That was okay for Petrosian as defending champion. As black in game 13, Spassky vs Petrosian, 1969, Petrosian defended against 1.e4 with the Petroff and drew rather painlessly in 25 moves. In game 15, his previous black, Spassky vs Petrosian, 1969, he also played the Petroff and drew even more easily in 19 moves. This was game 17 and Tigran Vartanovich changed his match strategy by playing the Sicilan here and the next game. He lost this one in 58 moves and game 19 (Spassky vs Petrosian, 1969) in 24 moves. So then the score was 5-3 to Spassky with 4 to play. |

 | | perfidious: From that disastrous nineteenth game--the quote might have originated from Bernard Cafferty, but my tired old brain is unsure: Spassky vs Petrosian, 1969 |
|
| Nov-28-15 | | Ulhumbrus: After 21...Rad8 or 20..Nxd5 it seems not easy for Black to advance his king side pawn majority but it seems also not easy for White to advance White's queen side pawn majority |
|
| Jan-29-18 | | otto80: what is the idea behind 45...f3+, I came up with the following line that loses for black 46. Kxf3 Rd3+ 47. Kg2 Rxb3 48. Rxc5 Rxh3 49. Rxa5 Rh4 50. Ne3 and white wins, am I missing something? |
|
| Mar-02-20 | | RookFile: Somebody said this was an obscure opening line. I'd have to disagree, anything played multiple times in world championship play is not obscure. |
|
| Mar-08-20 | | edubueno: 23...Nd5 24. Rxd5 exd5 25. h4 Rf5 26. Nb6 Bxh4 27. g3 Bxg3 28. fxg3 Rf8 and the position is not clear at all. |

| Mar-28-20 | | edubueno: 23...Nd5 24. Rxd5 exd5 25. h4 Rf5 26. Nb6 Bxh4 27. g3 Bxg3 28. fxg3 Rf8 29. Kg2 Qd3 30. Qc3 Qxc3 31. Bxc3 d4 32. Bxd4 Rd8 33. Re4 Rb5 34. Nc4 Rxb3 35. Nxa5 Rxa3 36. Nc6 Rd6 37. Ne7+ Kh7 38. Kf2 Ra4 39. Ke3 h5 40. Nf5 Re6 41. Rxe6 fxe6 42. Nh4 g5 43. Nf3 Kg6 44. Ke4 = |

| Mar-28-20 | | ewan14: With regards to when Spassky played against the Petroff twice and was happy with the easy draws , Spassky said he felt extremely tired at this time.
( Petrosian's second said they did not want to risk it a third time in game 17. Petrosian did do well with the Petroff against Fischer in 1971 ) |

| | perfidious: When Bill Hartston annotated Hartston vs Petrosian, 1977 for the BCM, his first comment was after 1....e5, and went something to the effect on how Petrosian usually essayed it when content with a draw, whilst plumping for a Sicilian when he was after more. |
|
| Mar-28-20 | | Granny O Doul: @perfidious: That line about "if Petrosian had retained the nerve" is from Wade & O'Connell's Fischer collection. When Petrosian chooses the Sicilian for Game 7 in 1971, they comment: "History is about to repeat itself". |
