This diffrence is even more dramatic that I found with Fritz. Probably you tried
in different way as well. For me "the end of the game" was usual end when still
around 11 pieces are on the board. In Fritz difference in numbers was between
220k and 320k at "the end". So only 45%. But for Crafty number is 333%. Big
