Somebody please correct me if >I'm wrong. Hmm, does this make sense? I mean: - if I'm testing killer book vs no book, I will win 100% of the games, just by picking 2 won games (with white and black) and put the moves in my book. - if I'm testing killer book vs random book not known by the book cooker (big enough to not repeat lines in a match), it's impossible to prepare killer lines for every possible game. In a match of 100, maybe 5 can be killer lines. That can't make for 700 elo points. - if the book cooker knows the random book in advance, we're near the first case in that it's a flawed test; it's cheating. So I guess Vincent had to be talking about professional book vs no book or professional book versus random book, without any cooking against a certain opponent. José C.
