Has this been tried before? My idea is that by saving the PV, i have a line to try instead of a move if i reach a position again. The idea being that if i have a 4 move PV tn the hash, and i want to search 6 play from here, i can play out the PV, and do a 2 move search, giving me hopefully a quick cutoff, and if not that, a really great try for a reduced alpha/beta window. I know it sounds expensive, but because of the way the rest of my program is structured, it's essentially free--or very cheap at least. This also opens up the idea of expanding the definition of what the PV is, so i'd get even more lines to stick in the hash table. dave
