Botvinnik follows analysis prepared for his match against Smyslov but soon runs into an extraordinary improvement. As it turns out, Black's 17th move is not a winning shot, but white's subsequent play permits Fischer to win a clear pawn. That ought to have been enough, but this battle of titans should serve as an inspiration to all who may find themselves a pawn down. Rather than give up, Botvinnik defended as precisely and vigorously as possible.
