Use EOC knowledge (menu Option ) Activating this option will enable REBEL to make use of the special EOC database that you have loaded during calculating. The EOC (encyclopedia of chess) database is a re-compilation of REBEL's standard database of 800,000 high qualified chess games stored in a new super fast format. This enables REBEL to consult the database and based on what is found to adjust its play. REBEL can use the EOC data in two ways: - Use as book: REBEL will search in the EOC database for the current position. If the EOC database contains this position REBEL will answer immediately with a next move found in the EOC database. We do not recommend this setting for optimal play but more as an option to study opening theory. The EOC database contains 20 million moves and its size is 20 times bigger than the standard opening book. - Strong or active use: REBEL will search in the EOC database for the current position. If the EOC database contains this position, REBEL will look at the next move(s) in the EOC database and use in its calculations the result of these games by adding or subtracting some points to that move. In this way REBEL will follow the human theory as represented in the EOC database of 20 million moves. The advantage above the EOC=BOOK setting is that the REBEL chess engine still is in charge and that major mistakes made by human players in the 800,000 game database are filtered by REBEL. Rebel Century 3 will play with the STRONG option against GM v/d Wiel next tuesday January 2. Ed
