Hi, what started as an attemp to get my program ( crazyhouse chess ) to play a reasonable opening when its opponent tries to kick it out of book (1.g3 or so) made me think about opening books in general. IMHO every program can get stronger when the author tries to make it play good openings even without opening book, that will help in the middle game as well. I believe that the ammount of memory taken up by "perfect knowledge" (Endgame Tablebases) will ever increase while the ammount of memory taken up by "human knowledge" (Opening books created by humans) will decrease. - Programs have become so strong that often times humans do not know better which move is best in a certain position. - Programs often get out of book in a losing line. - Programs often get out of book in a line they do not understand. - Learning features become better and better, so programs will "learn" openings over time anyway. - A single program plays many more games than a GM in a given time period, so to learn from its own games which are far more predicatble and contain far less blunders which change the outcome of the game completely makes more sense. This might not be true for very small expert written opening books, but I think it holds true for the Crafty style books. What do you think ? Georg
