In Diep i just have 1 file there and i'm using the values in the EGTB as 'winning from side to move'. So compression code would compress it to the exact same sizes too. Perhaps Eugene forgot to turn on fsym in his EGTB code. That's the problem if you do everything by hand i guess. In diep things go automatic. No need to turn things on by hand. >Don't exactly know how that would (should) differ, but it's the only explanation >I can come up with. > >Tony > >> >>Regards, >>Dieter
