The REBEL Opening Book has been expanded with 60,000 new moves. The Rebel opening book has now over 46,000 variations resulting in 2.6 million positions.

The REBEL database is the life-work of Jeroen Noomen who spends over 700 hours a year to build his ultimate Opening Book. Jeroen started his work for Ed Schroder at the time Mephisto chess computers dominated the world both working for Hegener & Glaser (Munich, Germany).

When Mephisto Hegener & Glaser went down (1992-1993) Ed and Jeroen left Hegener & Glaser and Jeroen joined Rebel company. Jeroen's job:

. Create the best opening book in the world;
. Assist Ed in developing Rebel concerning the playing stength of the chess engine (advises and testing).

At the time Jeroen worked for Hegener & Glaser Jeroen developed the first REBEL book for the Mephisto Polgar and later for the Mephisto RISC the world champion program of Madrid 1992-1995.

Typical for the REBEL book that it is always up-to-date concerning the latest new opening theory. Furthermore one of the main advantages of the REBEL book is that it contains a lot grandmaster analysis on critical positions of human theory.

REBEL will play these grandmaster analysis too and therefore REBEL is even able to surprise the most experienced GM experts in opening theory since most of these lines are not tried in GM tournaments.

Last but not least the REBEL book is tuned for the playing style of Rebel-Tiger II and Rebel Century 3.0, a giant job.
