Just the thought of experienced programmers like you running "strings" on my engine and seeing all the silly debug output strings and similar stupid stuff makes me feel embarrassed. :-) >>Actually the unit is "binary centipawns", meaning pawn=128. > >Ah yes (picture of hand slapping head) I remember you saying this before. No reason to slap your head -- I never remember this kind of details about other engines. By the way, the scores Gothmog reports to the GUI are always translated to ordinary centipawns. >> In other >>words, the position under discussion is evaluated as -0.59.

That's how I would do it, too. Tord
