Addressing the theory that Fischer was afraid to play again after becoming world champion Kasparov writes: "Brady’s dismissal of this theory misses the point: 'What everyone seemed to overlook was that at the board Bobby feared no one.' Yes, once at the board he was fine! Where Fischer had his greatest crisis of confidence was always before getting to the board, before getting on the plane.
