Opening Books

Source code Pro Deo Book

The Pro Deo (Rebel) opening book as open source. 5 minutes away adding the best non-commercial opening book to your chess engine. A huge thanks goes to Jeroen Noomen for this gift to non-commercial chess programmers.

Download Source Code version 1.0 and read the documentation in the BOOK.C file, basically this page.

Windows, Pascal and Delphi programmers can use the rebelbook.dll created by Andres Valverde.

Include BOOK.C into your project and compile.

MAINBOOK.BIN - The big mainbook.
TOURBOOK.BIN - Selection of favoured opening lines 
               called the Tournament Book.

Initialize   - Call the routine INITIALIZE() once.

Operation    - Create an EPD string from the current 
               position and strcpy it into the string 
               EPD, then call the routine 
               FIND_OPENING() to search the 
               opening book.

             - When a move is found it is stored into 
               the strings FROM and TO in Ascii format
               so E2 and E4, else the strings are 
               empty. Play this move. That's basically
               it.

Edit         - Opening Books can be edited using the
               Pro Deo DOS edition.

History      - The opening book is the intellectual 
               work of Jeroen Noomen who started his 
               work in 1989 for the Mephisto MM4 module
               from Hegener & Glaser which later became
               the base of the REBEL series. The book 
               is the result of 15 years diligent 
               hand-typed work.
