I did not use a book that favored any program. I don't favor one program over another when I test. And I always reset the learning when I play a new match at different time controls. The computer picked the move Na3, I choose no openings for it. I guess that line was played because when you share a book, book learning is trying to win, but can't because it is playing itself. I think the match was as fair as I could make it, but if amir has a problem with the way I did the blitz match. I will replay it with Junior's book. I don't care, I just know when playing blitz and you have two evenly matched programs, a bigger wider book give that program a huge advantage. Even when I play fritz vs fritz and give the huge book to one of the fritz programs. That Fritz will win big time at blitz time controls. > >Uri
