I can use that book, but it is very small, and I didn't implement book creation
out of database. The main Falcon book, falcon.bok, was created out of a database
of about 120,000 GM games. It contains about 470,000 positions, whereas the
Genesis book has no more than a few tens of thousands of positions of a lower
quality (and it doesn't support transpositions).

Feed the interface a pgn database. It will take care of the rest :)

I totally disagree with you about this. IMO opening book is one of the most
important parts of the program. Look at the games in Graz, many games were
already decided after the opening phase...
