Use EOC knowledge options:

BOOK: use the EOC data as an opening book, moves are chosen via a formula
using the percentage, elo and number of games;

MODERATE: use the EOC data via the same formula to add a bonus to each
available move. In this way Rebel will follow human opening theory as
found in the EOC database.

STRONG: same as MODERATE only that the bonus is double.

Typical for STRONG are bonuses between -0.50 / +0.50

Example of STRONG: 1.d4 1.d5 and Rebel will play 2.c4 all by itself
because of EOC.

The information is shown in the INFO window.
