But someone (namely the programmer) might want to disable Nalimov's code completely while the program is still running, and needs the memory back. That's what FCloseTB is good for. There is of course the "cosmetics": I usually do not want to leave cleanup (of any kind) to the OS. Too much bad experience with MS products... :-( Regarding the Fritz question, I cannot tell. I could be that the memory woun't get freed when you exit the engine an load a different one. I do not now, how Chessbase handles that. But Nalimov's original code leave the cleanup for the OS when the whole program exits... Marcus
