  offramp: 43.Qc3 might have been stronger.
Mar-01-06  Maynard5: The critical mistake here appears to be 38. ...Rb4. This was one of Petrosian's thematic exchange sacrifices. However, Korchnoi's refutation is quite skillful. Black's best option in this position would be passive defense. In this case, White's only chance is a breakthrough on the Kingside by g4, h4 and g5.
Mar-26-10  M.D. Wilson: Korchnoi beats Petrosian at his own game.
May-13-13  kingfu: A more active defense would be to not exchange the rook for a bishop, get the bishop to e8 and run the knight to f8 to d7 then c5.

Classical games: Viktor Korchnoi beat Tigran Vartanovich Petrosian 12 to 11, with 47 draws
