Hello, A while ago it was posted here that movesorting near the root was much more important than near the leafs. - Is that true? - If so, how much more important? For instance Crafty has a FH FirstMove/FH rate of 94%. Now most nodes are near the leafs, on average 94%, so near the root it is probably a good bit better. Say 98%. Many moves come from hash, there. Now what if it went from 98% to 99%? What would be the impact on total nodes? Any ideas? If sorting near the root is more important, isn't it an idea to try to improve sorting for the first couple of plies (say 3) by Enhanced Transp Cutoffs? Some reported rootsorting by failsoftvalue gave good results. Why not the first 3 plies try something similar? Regards, Bas Hamstra.
