I could read "score" from my attack tables, not just any "information" ,fairly complete information relevant to attacks. I can do the following:- int precalculated_queen_partial_mobility_wrt_knight[64=q][64=kn]; I have "precalculated"+ "mobility" that helps in my eval_mobility() call and so it pass; I did not say in my advertisement flyer ...complete breakthrough in chess evaluation that do away with the traditional way chess programs need to compute mobility,completely replaced with precalculated table lookup... Common sense sometimes is trustwothy but I'll still leave an inch just in case some idiot-savant really have a break-through beyond our mortal minds. But I'll still rather bet the chance is greater that within the next 100 years commercial fusion replaces petroleum as the main source of energy. Rasjid
