| Apr-04-17 | | cunctatorg: A real pride to score such a beautiful win against such a defender as Petrosian was; to be honest, this might very well be a Bobby Fischer game!!... |

 | | Gregor Samsa Mendel: <RookFile>--From Robert Byrne's book on the 1974 Candidates' Matches, after white's 14th move: "Portisch has now attained the classical attacking formation originated by the brilliant American grandmaster Harry Nelson Pillsbury. Whatever chance Petrosian has now lies in striving for simplification with 14..Nfd7, but he misses it." |
|
| Jul-16-17 | | RandomVisitor: Black still has to play precisely after the suggested improvement 14...Nfd7 in order to diffuse the white attack:

 | | offramp: Today's pun is based on the phrase "Port Authority". Most big ports have a post authority. Not Rotterdam, though. That just has a big hole in the ground. The one in London (POLA) used to be housed in the most magnificent building I have ever seen; a building that is now a mind-boggling hotel: the Four Seasons Hotel London, at Ten Trinity Square, overlooking Tower Bridge and the Tower of London.

| Jul-17-17 | | Petrosianic: It seems that there were a lot of Candidates Matches in which the loser scored the best win of the match. In the 1974 series alone, I liked the loser's win best in Korchnoi-Mecking, Petrosian-Portisch, Karpov-Spassky, Korchnoi-Petrosian, and Karpov-Korchnoi. And there might have been more than that if the loser hadn't won ANY games in the other two matches. |
|
| Jul-17-17 | | Petrosianic: Now I remember from Byrne's book on this match that he didn't like 9...b6, and suggested instead 9...e5! 10. dxe5 Ne8, and Black will pick up either the c or e pawns and more or less equalize. |
|
| Jul-17-17 | | Howard: Some have said that Game 13 of Karpov-Korchnoi 1981 was probably the best game of that match. Korchnoi won that game, but it didn't exactly do him much good as far as the overall match. For the record, my favorite game from that match was Game 4---vintage Karpov ! |
|
| Jul-17-17 | | Petrosianic: Maybe. I liked Game 9, but you could make a case for Game 13. |
|
| Jul-20-17 | | Howard: Certainly nothing wrong with Game 9 ! Classic case of how to play against an isolated pawn. |

|
| Mar-10-20 | | Gaito: 7...a6? is a mistake, known since 1922. It was first played in a game Alekhine vs. Bogoljubov, Hastings, 1922, 5th round. Alekhine of course punished it with 8.c5!, whereby the square b6 was critically weak for Black. Portisch was on the receiving side of that mistake when he himself played 7...a6? against Hort in Madrid, 1973. Hort naturally knew Alekhine's refutation and played 8.c5!, and eventually won in good style. Well, Portisch learned his lesson, did his homework, and now Petrosian was the one who made the same old mistake, and the move was refuted by Portisch. A very curious chain of events. The moral of the story is that it pays to play over Alekhine's games once in a while. |
|
| Mar-11-20 | | Petrosianic: <Gaito>: <7...a6? is a mistake, known since 1922.> No, it's not. Black is fine after 9...e5, due to the weakness of the c pawn. 9...b6? was a weak move, though. |
|
| Aug-23-21 | | Gaito: <Petrosianic:. No, it's not. Black is fine after 9...e5, due to the weakness of the c pawn. 9...b6? was a weak move, though.>
Yes, thank you for the correction. To be sure 7...a6 is no mistake at all. I already mentioned elsewhere (Hort vs Portisch, 1973) that 7...a6 was played many times in the match Capablanca vs. Alekhine, Buenos Aires, 1927. Sorry for my bad judgment. The "delete" option of my previous comment has disappeared. I had the (wrong) belief that since Alekhine had beatten Bogoljubov at Hastings 1922 after 7...a6 8.c5, then the move 8.c5 could be a sort of "refutation" of Black's 7...a3. (Alekhine vs Bogoljubov, 1922) That was a wrong assumption on my part. Sorry. |

| Feb-21-22 | | Ulhumbrus: On 14...Nfd7 Black has displaced the defender of h7 and White can try the Stonewall type attack 15 Bxh7+ Kxh7 16 Qh5+ Kg8 17 Rf3 eg 17... g6 18 Qh6 Nf6
19 Rh3 Nh5 20 Nxg6 fxg6 21 Qxg6+ Kh8
22 Rxh5 mate |

| Feb-21-22 | | paul1959: <Ulhumbrus> You are half-right: Computer analysis shows that the Black King escapes after 17... Nxe5 and 18 ...f6. However, Black is always one move from disaster in this variation. Byrne could move his pieces in his analysis , not Petrosian, so no wonder he rejected 14... Nfd7 |

19 Rc1-f1 fxg5 20 Qg6! threatening 21 Rf7. Then on 20...Qe8 21 Qxe6+ Kh8 22 Rh3+ Qh5 23 Rxh5 is mate, so that does not work. Perhaps the computer has an alternative to this which enables Black to escape by a single move. |

| Jan-16-23 | | N.O.F. NAJDORF: 29...Bc8 or Bd5 30. Qe5+ Kg8 31. Rxf5 wins |
