Mr Uris asked me what is the logic behind the unequal values of the queens and rooks. I do not have a test which prove with 95% confidence that the personality with the unequal values is better than with the equal values, but this is what I observed during the mini match between CMQueen+ vs Chess Tiger 12.Oe. In order to gain a strong midgame attack you need to instruct the program to keep its queen and rook as long as possible and also to keep its bishops in preference to the knights, unless the knight gain a strong post like the center for instance. During most of the games in which Tiger obtained the better position with its queen or Tiger Queen got close to the CMQueen+ King then CMQueen+ immediately traded Queens. In the case of the rooks CMQueen+ traded its rooks as soon as Tiger 12.Oe rooks were more actives, in two case CMQueen+ did whatever it could to trade Tiger rook which was placed on the seventh rank by mobilizing its rooks until it finally traded it in one game, and forced Tiger to reposition its rook to another rank, this was almost human like style. Now as far as its bishops being rated a little bit higher than its knights, CMQueen+ avoided at any cost to trade its bishops for the knights, unless the position was forced or was such that in order to avoid a fork, in which it was going to lose the trade then the program traded bishop for the knight.
