|Oct-07-04|| ||morphy234: Black's queen isn't trapped. |
|Feb-09-05|| ||prinsallan: Looks like the Black Queen can escape, but to what price? If 23... QxG5, then 24: QxF7 and White should win easily ? |
|May-01-05|| ||queensknight: No, no, no...the black queen is definately not trapped. But since the queen must leave its square, it will no longer be able to protect the knight. White simple wins after taking the knight with the queen and it's mate in the next few moves.|

|Nov-17-05|| ||Koster: 23..Qxg5 24. Qxf7 Bxf1 25 Rxf1 with slight material and huge positional edge. Ne6 is threatened and the d pawn is pinned (lost)and stopping white's e pawn will cost black more material. Korchnoi was right to resign and probably decided right there to switch to the Leningrad Dutch.|
|Nov-17-05|| ||Koster: <offramp> 25. Ne6 no doubt wins too, but why give black 25...Qe3ch?|
|Nov-17-05|| ||offramp: <Koster: <offramp> 25. Ne6 no doubt wins too, but why give black 25...Qe3ch?> |
I have no idea; 25.Ne6 was not my concept.
|Nov-18-05|| ||PARACONT1: By logic of elimination: Black's rook protects the d5 pawn. Exploit the weakness. But the Kt protects the rook. So exploit the Kt! Wait! The Q protects the Kt. And nothing defends the Q. Exploit the Q! It is the weakest link and once it moves everything crumbles! Brilliant stuff from Petrosian.|
|Dec-17-05|| ||DeepBlade: Pure logical move, attack the defending piece, also called undermining. It is the prepatarion (the heavy comlicated exchange of pawns and pieces in the center) that is the hardest thing in chess.|
|Jul-18-07|| ||Davolni: I think this is Petrosian's first game agains't Korchnoi out of total of 71 games (at least in the database) when he was only 18 where Korchnoi was 16.|
|Aug-26-07|| ||euripides: A seamless-looking win for the young Petrosian.
Black probably goes wrong as early as 7...0-0, after which his results in this database are absolutely terrible. 7...Qe7 prevents Ba3 for the moment and gives an interesting game.
|Aug-28-07|| ||wolfmaster: Great win by the teen Petrosian, even though he had not yet developed his "Iron Tigran" style.|
|Oct-15-07|| ||hesyrett: I agree with "Euripides". As a long-time Dutch Stonewall player I'd say the teenage Korchnoi made a novice's mistake by castling on move 8. Black's P structure really needs that black-bound Bishop. By playing 8...Qe7 he can prevent White from swapping it off.|
As for the circumstances of the game, recall that Leningrad had suffered a terrible siege at Hitler's hands just a few years earlier, so Petrosian and Korchnoi were lucky even to be playing chess. Not too much later on, they got the best coaching available at the time, but in 1946, I doubt it.
|Jun-26-08|| ||Ulhumbrus: The game suggests two ways in which a pawn attack in the centre can hinder an opposing King side attack.
The move 20...Rd8 suggests that the opposing centre becomes a target, and draws pieces away from the King side attack. The move 21 Qc7 suggests that a file opened by a pawn exchange can be used to invade the opposing position.|
|Jul-14-08|| ||apexin: wow, what a game|
|Jul-14-08|| ||brankat: <apexin> At the time Petrosian was 17, and Korchnoi 15!|
|Jul-15-08|| ||apexin: <brankat> that shows how talented they were.I think this game was included in chernev's 62 Most Instructive games of chess ever. 16.e4! is very strong|

|Aug-09-12|| ||backrank: After 23 Nf4! Qxg5 I think it is simplest to play 24 Rfe1!, saving the rook and supporting the passed pawn on e5 at the same time.|

White has then at least 4 powerful threats: Qxf7, Ne6 (now - thanks to the R on e1 - undisturbed by Qe3+), Bxd5 and e5-e6.
That's too much for Black.
|Aug-09-12|| ||LoveThatJoker: Guess-the-Move Final Score:
Petrosian vs Korchnoi, 1946.
YOU ARE PLAYING THE ROLE OF PETROSIAN.
Your score: 41 (par = 39)
|Aug-13-12|| ||marljivi: After 16.e4! blacks position is more or less strategically lost.Probably the most stubborn answer was not 16...Sf7?,nor 16...dc4?,nor 16...fe4?,but the developing 16...Nf6,covering at least square d5 and therefore preventing white to open up the c-file.In case of 16...fe4? 17.fe4de4 it is obviously unnecessery to find/proove the exact win for white,since black has paid too high price for the pawn(his pawns are like Swiss cheese-actually,Korchnoi now lives in Switzerland-,he is playing without rook on a8 and bishop on c8,the f-file is open,and his dark squares are weak.So that after 16...fe4? 17.fe4de4 (17...Rf1 18.Qf1de4 18.Nc5Qe8 19.Ned7Bd7 20.Qf6Kg8 21.Qg5Kh8 22.Qf6Kg8 23.Ne4 ,or 23.Be4 ,or worse,but probably still sufficient 18.Nd7?Bd7 19.Qf6Kg8 20.Nc5 with clear edge for white,and after 20...Rf8?? 21.Nd7 .) already 18.Rf8(?)Nf8 19.Qa3ed3 20.Qd6Bd7! 21.Nd3 gives white decesive positional advantage.(But not 21.Nd7??Nd7 22.Qd7d2,etc.) However,I managed to find a forced win for white.He plays 18.Qa3! (instead of 18.Rf8) and now:|
a)18...c5(?) 19.Rf8Nf8 20.Qc5ed3 21.Qd6Bd7 22.Nd3 (Again not 22.Nd7??Nd7 23.Qd7d2,etc.)

Korchnoi was well-known in Soviet union as a "pawn-grabber",so if he didn't accept the sacrifice 16.e4!(and if Petrosian offered it!),then the sacrifice simply has to be sound.
