“When Petrosian was preparing for the match against Fischer, especially when analyzing Fischer’s games against Taimanov and Larsen, he came to the conclusion that besides his chess strength, there must be something else that helps Fischer win. Something significant yet elusive, as it remained unnoticed. To perceive it, one needed to look at Fischer’s moves beyond the chessboard.
