I looked for the same thing myself, but eventually gave up and put together a pgn file (few megabytes) of world championship games from the FICS ftp site. (I also included the text of the ECO pgn data file from the same site). I then just crunched this through an algorithm in my program which builds an opening book. - Dan P.S. I could have used a lot more games, but I wanted the final version of my opening book (with moves played only once or twice culled) to be less than a megabyte so my whole program fits on a floppy. Even this small opening book seems to get my program in reasonable positions most of the time. > >Thanks, >John
