So lets not >overestimate this preparation issue. Let's suppose that they give him a bogus book. I would (personally) just use whatever book comes with the package. So the "bogus book" idea (proposed by me) does not really work anyway. I don't expect (in any case) that the game would follow the same exact line as he found in practice [though it is not inconceivable]. Rather, that he would be able to discover some sort of systematic weakness. For instance, blocking formations might be formed in a certain manner, etc. I still think the "preparation" notion would be a big advantage for the human GM -- definitely bigger than any of the others. On the other hand, I don't know if it is unfair or not. The computer could prepare by analyzing each of Kramnik's games for the entire preparatory time and look for things to exploit in the other direction.
