Now I'm knowing really more than before! The last ones: >1. What parameter do you recommend creating a really good new book.bin for >Crafty? > And books.bin?? I don't believe that (at present) it is possible to create a "really good book" from pgn game collections. There are too many mistakes, blunders, refuted moves, and so forth. This is a tough problem to do automatically. >2. Is your "enormous.pgn" better than Dann Corbit's PGN opening folders under > ftp://cap.connx.com/pub/a-openings/ and following? No idea. Dan knows what I have. I believe what I have came from what he has, which means if you combine all his stuff you get the file I use.
