I don't understand this point. Permit me to be a bit facetious, but surely
by this argument I could claim to be World Champion on the grounds that when
I lost to Polgar, Kramnik, Kasparov etc, I was intimidated by the fact that
I couldn't understand why I kept losing. And when I asked them how they kept
beating me they declined to answer. Surely I am the same player whether or
not I am intimidated? If Kasparov was confused and intimidated, I think it
was because he was ill-prepared for the match. And since he'd signed a
contract accepting the conditions of the match, I would say that that
was his own fault. I say this as a person who was hoping he would win.
