Ed said that when Rebel was out of the book, after 15..Rb7 the machine crashed. So that of there in before it becomes difficult to do an analysis of Rebel's moves, but I made some tests with other programs, and I think that they don't analyze well the position, because the evaluation of the candidates moves are very similar. The first move played by white after the opening was 16. Qc1, a doubtful movement(I read now in a Ed's post some words that confirms this). 17. Bh6, 19. Ra2 and 23.f4 don't also seemed good moves. I think that soon after 23.f4 Rebel was already in an inferior situation, and agaisnt a GM this can means a lose. The book used was the same as it was used by Rebel in the World Championship in Paderborn, would not be very important for Rebel use a specific opening book for the games against GMs? Only a question. Paulo
