Sounds like a good idea, but I wonder about >the effect of not having any move ordering info for the >rest of the tree. think about iterative deepening ! You have move ordering for the rest of the tree ! Because most important entries from last search with old age will be marked with the new age because of iterative deepening... At least in most cases the main variants for all moves... Another I get from Jochen Peussner, instead of just keeping the PV in a several table you could also save the main variant which leads to the last cutoff in a table... so far I have not experimented with it, but I will do in future... it is not of big interest for blitz games, but with high depth this could be interesting.
