Bob do you take "batteries" into account? IE if some sliders are lined up does swap always give the correct value? And checks? Do you allow a "swapmove" when the moving color leaves itsself into check? Of course chepest is to do none of that, but I have no idea how that hurts. By the way I switched from incremental to normal move generation, basically to get better sorting, but so far the incremental version was a lot faster... Only doing very basic full window alpha-beta and material, no null, no extensions, it spends over 40% generating captures. Regards, Bas Hamstra.
