I know of multiple programs that use a 'anti-human' evaluation.  And one big
mistake is "queens on = +1.00" which often leads them into getting attacked
terribly by another computer because they try at all costs to keep those queens
(and tactical threats against humans) alive.

IE Vincent (Diep) seems to have a high value for a queen... and I have seen it
get into serious trouble in endings where it has a queen for 3 minor pieces,
and thinks it is well ahead.  Crafty thinks the three minors are murder against
the queen and it is generally right...
