Hi, For those who spoke about the difference between "legal", "illegal" moves based logic. Question was: What logic will be more rapid? After my trial, legal moves based logic do the best. Difference insignificant and is around 4%. What exactly was changed and where? 1) Before only ply zero had illegal moves based logic. All other plys used legal moves logics. 2) Were changed three plys over ply zero to see the difference. 3) Tryed both logics for speed 8 plys deep, brute force, same positions. No extensions. 4) In illegal moves based logic all old alignment procedures are the same. For instance, procedure that put "checking moves" at the head of moves line. This last procedure is as much big and time consuming, as the procedure that before watched for legality of all moves in a ply. Leonid.
