The piece square table is only changed in the endgame. It can be improved by better order of moves and it can be also improved by better extension and pruning rules(it is using only some futility pruning today and it does not use partial extensions) but inspite of all the problems the latest version could beat Faile with no book 6-4 in a match(time control was 1 minute/40 moves,2 minutes/40 moves...5 minutes/40 moves) It also lost 8.5-1.5 in a match against GNUchess5.03 in the same conditions. hardware was one pIII800. I believe that Faile and Gnuchess used hash tables in the matches(I told them no instruction about it but usually programs with hash tables use some hash tables by the default option) Uri
