Nov-22-05		fred lennox: To advance to the semi-finals, white needs a win, black needs to draw, so Korchnoi has the edge despite being black. 8.0-0 is inconsistent. A waste of tempi since the king is safe at e1 after 7...Bxc5. As it turned out the king is not safe on the kingside since black's minor pieces is pointing in that direction. He may of been relying on black to 0-0 but with blacks superior minor pieces, Korchnoi can gain a tempi. If white wanted to castle, he could of eliminate some minor piece pressure by 7.a3

Jun-05-07		outsider: that's it. petrosian hated being pressed to win at any expense, and he used to play such games poorly (he needed to win before the last game, but not by the last game). here we get that he is clueless and has no idea how to attack the reliable position of korchnoi. korchnoy (as i understand) never risched losing this game.

Aug-08-12		RookFile: Well, perhaps Petrosian should have played 7. a3. Not that it wins, but it goes to work in creating imbalances that make the game more likely to be decisive than a draw.
