>A question: Which one do you think is better: generate non-capture before >history moves or do the history moves (and check if they are valid like checking >hash move) before generating non-capture moves? Usually history moves are not like killers: we don't have a few moves stored that we can try. Usual implementation is to mainatain an array history[64][64] that holds an integer values for every history[from_square][to_square]. The higher the number the better the move has been. So it's not a good idea to check the validity of these 64*64 moves :) Answer: I generate non-captures and sort them based on their history values. One has of course a lot to experiment how to actually increase move's history value and if they should be erased or reduced after search is complete. Severi
