I would like to know why they work for you (if). I have tried doing a null window search in the first root move with (prev_score, prev_score+1), to decide if to research up or down. But that is not better than just a (prev_score-window,prev_score+window), is that normal? I mean, if not even that works well for me why should I think MTD will? What do you get if you do the first thing mentioned? And do many null window searches in the tree have never worked very well for me. No more than 1% or 2% gain. Even only using them when there are ht move of exact score and the window is very big I have that 1% or something. I have heard PVS is a lot better than alphabeta(with small and nulls windows in the root of cors), yea sure... What difference you get using pvs or using alphabeta with aspiration search? Well, am sorry to bother you. Be well...
