Mike or Bob, sorry if you've already clarified this before somewhere, but I was wondering if you can help me understand Crafty's optional bookc.bin and when to use it / not use it. On some other sites/posts I've seen the following: "Bookc.bin which you can download with Crafty is in fact no more than a ordinary books.bin file...It was built from the file start.pgn but after removal of unsound , especially gambit lines to ensure that a more suitable book can be built against other computers." This would seem to indicate that it is recommended to use bookc.bin in computer matches, but I've also received the advice to remove it even in computer matches. Bookc.bin (from the UAB ftp site) seems to do more than restrict unsound gambit lines, in my results I've only seen it play 1. D4 from White. Congratulations on the continued good performance of Crafty :) Thank you, Tom
