> > optimation options used: > -o6 -fomit_frame_pointer Anyway I would recommend you to experiment with -mpreferred-stack-boundary=2 because most of chess program does some kind of recursive game tree searching that can be importantly slowed down by stack alignment issues. Other options you might try are -funroll-loops (that usually helps to such programs) and enable tunning for your cpu (-mcpu=<cpu>) supports x86, pentium, pentiumpro and k6. Honza
