Of course, I have no idea what might have happened before >the upgrade. I have more ram but it is not the reason for what happened at depth 15. I tried to give my fritz5.16 44MB hash tables(44*1024Kbytes=45056Kbytes) and my results at depth 15(I asked it to analyze and not to play): 1)Kg1 has evaluation of -2.34 after 14 minutes and 46 seconds fritz5 looked at 214418 Knodes to discover it. 2)after 17 minutes and 20 seconds Fritz prefers Qd3 with an evaluation of -2.31(this is not a final evaluation and fritz is "thinking" about Qd3). Fritz5 looked at 257269 Knodes to discover Qd3 >> >> >>> It seems to me that the ply >>>numbers take longer to rev up than they used to. >> >>The ply numbers are not important >>It is possible that the ply number take longer because the program sees more in >>low plies. >> >Doesn't (for example) 8/15 mean that absolutely everything is examined over 8 >half-moves?
