Petrosian discussing his forthcoming match against Botvinnik with his second, Boleslavsky:
"I told him that I believed that I should play against Botvinnik the same way I played against everybody else -- not strive for complications at any cost, but not to avoid them either, if the opponent threw down the gauntlet, and it appeared that my prospects in a given position were favorable. Not worry about the possibility of simplification of the position. And, if I found myself in a difficult position, to keep my pecker up and not drop my head."
