Hi After reading the posts regarding hashtables, where Robert Hyatt and others show that the most significant improvements is in the 24M-96M area I was thinking about the whole hashtable thingie... Reading some papers(of course i forgot which, i will try to locate again) it seems that stuffing more of the PV in the hashtable will improve the efficiency another notch(article states 3% in middlegame and 12% in the endgame) As i recall they stuffed 2.5 ply PV in the hashtable. So what i am really asking is this : 1. Have anyone ever tried to put longer lines of PV in the hashtable ? 2. Could there also be a "better" number for how many ply's that should be inserted ? I was just thinking instead of using a big hashtable, maybe it would be better making a bigger entry with PV in it instead. Mainly because the efficiency dont really skyrocket when we get over the 24M-96M size. Of course im on work doing some really boring administrative tasks, so i may just be daydreaming..... Any thoughts or comments ?? Regards Kim
