I try to find a big PGN file with games >from Grandmasters with ELO greater than 2600. there are some files like that, which you can download with chessbase(8) i also have made a Elo2400+ file, to start making a opening book for Bas Hamstras program Tao (but he still busy with some code, i think, booklearning etc.) >Then I re-format the PGN file so my program can read it, and create a opening >book for the program. *the* program to make the book, eg in EPD format is *bookbuilder* (superchess.com); with the old version 3.6 you can choose to load in positions which occur more than once, and this will compress the book *and* ensure a higher quality. But indeed, some hand tuning also is very important, eg to tune the book for the specific engine you have, or the tune it into the playing style you like to have. Some interesting books can also be found on the Arena site (and used with Arena program). good luck, Jef
