Dr. Hyatt, Yes, I was referring to absolute meaning +=good for white and -=good for black and relative meaning +=good for whomevers move it is -=good for the other color. e.g. When it is analyzing when I'm the black player, -1.40 for the moved played vs -.60 for what crafty selected indicates that white (my opponent) is actually +1.40 (absolute) for the moved played and would only be +.60 (absolute) for the selected move. Am I interpreting the score correctly? If that's the correct interpretation, I can write an awk script to change the scores when I'm the black side. Thanks. Steve
