I thought Kasparov had a perfectly reasonable argument that in a human v human contest, the players and any coaches have access to a public record of all previous contests the opponent participated in, and can use this information to prepare for a match. Deep Blue had Kasparov's record, but he didn't have Deep Blue's record, which is lopsided.
You are always exploiting the flaws of your opponent in these games. Winning is a matter of exploiting more than you have been exploited.
Exactly. Human player are never given enough of a chance to exploit the AIs. When an OP strategy exists in the metagame literally the whole playerbase tries to exploit it, which is how the metagame evolves. No such process exists for playing against AIs.
