Mine is wrong here. The static evaluation is +.63. It jumps quite a bit, but
then
slowly settles back down to a draw. Crafty likes this because of some recent
changes
to the endgame code to better detect split vs connected passers...
material evaluation................. 0.00
development......................... 0.00
pawn evaluation..................... -2.11
passed pawn evaluation.............. 0.06
passed pawn race evaluation......... 0.00
king safety evaluation.............. 0.00
interactive piece evaluation........ 2.68
total evaluation.................... 0.63
