Yes Aristarch Time management in "game in x minutes" is probably not so good (I am not so sure though), but 40 moves in 40 minutes seems to work great. I have played some games myself, and Aristarh played almost equal to Hiarcs 8 and shredder6 on those following games. And now against Fritz7 it's winning games! I agree that it is exceptionall interesting program, the last time I was so excited about a new free program was when YACE first came out. cheers, pavs
