There variety is _critical_ or the opponents keep finding book lines that lead to trouble for Crafty. With a wide book, they have a much harder time. For matches, I would certainly play with "aggressive learning". As far as "3% moves" I don't know what that might be. IE I don't (to the best of my knowledge) have any "play 3%" lines in my book. As far as "narrow" my basic book is made from "enormous" and you can't get much wider than that. My "bookc.bin" simply controls the first couple of moves carefully, but then leaves the rest of the book moves wide open, for the program to choose among. I can't distribute a version that works for all cases. IE how could I know whether you are going to play against it yourself, play against it using a computer in a match, play it on ICC, play it in a computer tournament, play it in a human tournament? All I can do is release something that will default to fit the most common usage, which is play against the "owner" in most cases. I should probably add a "mode match" and "mode computer" to go along with the "mode tournament" and "mode normal" options. Perhaps a "mode ICC" as well... If you try to use it in an important way, the best idea is to ask. :) Then I can tell you how I would do it. And in a match against a single opponent, I'd go for aggressive learning and put the onus on the opponent to thwart it if it can. :) >All the best, >Peter
