I cloned Chessmaster with Bots Manager, white with the ET book and black as the regular CMX book. This is the result of a match, ET is way better than the Ubisoft book for Chessmaster because it takes it out of its book and confuses it every step of the way in addition to having over double the depth of the CMX book to make calculated risks that The King engine does not foresee in its calculations before it moves.

It plays like a player from the future, I think I invented a hypermodern style. It's a useful book to watch games and train against to learn how to confuse chess engines and people from it.
