You have two choices, use chessbase books with Crafty. Or if you use Crafy via the wb2uci convertor, Crafty opening book (in crafty format) will work with chessbase gui. The book needs to be in directory without space and you need to add the "bookpath=" line in the wb2uci.eng. Search wb2uci on google for more detailed instructions on usingthis utility. If you are referring to the chessbase native version of crafty, only chessbase books will work with it. There are Crafty books at Bob Hyat's ftp site or you make you own using crafty and pgn files. "book create 44 1 .5" will make the main book from the pgn file 22 moves deep (44 ply) with all moves played at least once and scored 50%. "books create 16 3 .55" will make the start book from the pgn file 16 moves deep (32 ply) with all moves played at least 3 times and scored 55%. Note the "s" added to the second "books" command. That signifies crafty to make the start book. Without the s, crafty will make the main book. The file books.bin will be the start book, the files book.bin with be the main book. Crafty will use both books, using the start book first and then the main book. The settings above for the start book will make a higher quality book (better opening moves) than the main book, but the start book will be smaller than the main book. You adjust the size and the quaility of the book by adjusting the settings used in creating the book. Some people like to make books 60 plys deep, (30 moves) , I do not. In some cases, after 30 ply you already in the endgame, and I'm interested in watching Crafty compute the moves in the middle game as opposed to following known book lines right to the endgame. good luck!
