I'm trying to understand the difference between reducing the overhead in qsearch and futility pruning. On ply one of qsearch is it best to try all captures that can possibly change alpha without say using a SEE? And if the positional bonuses relative to a capture can only change by a max of say 100 can you safely say that if the value of the captured pieces plus the evaluation value you have when you entered qsearch plus 100 is less than alpha it need not be played? Should there also be a beta test? While i want speed an accurate qsearch is more important to me than a fast one. My understanding is whatever you capture on ply 1 of qsearch you never improve your score beyond that. On ply 3 of qsearch if you have an even better capture your opponent will pass to move on ply 2. thanks Mike Adams.
