Opening book conversion application

 

This application is intended to convert native or PGN databases to the opening book format.

It is possible to convert multiple databases into a single book file.

The maximum number of moves from each game to add can be set. Selecting a high (e.g. 999) number will add the whole games to the book.

If desired only the white or black moves can be added.

 

Also make sure there is enough free disk space available, a book file takes much more space then a database. Average 10-20 bytes per position is used, so to create a book from the first 15 moves of 100000 game would take: 100000 x 15 x 2 x 10 = 30000000 = 30 Megabyte  !
