This was nothing fancy, just a suggestion to treat the hash setting by the user as maximum only. Then first check the true free memory (I dunno hope there is some windows api function ?) so that if userX has 96MB ram and usually uses only one program at a time and has set hash tables to 60MB his HD doesn't begin to swap when next time he uses Shredder with say Outlook+Word in memory as well. In a seconds step decide on how much hash to use depending on time control, since clearing or "making old" big hash tables between moves may hurt in very fast games. Thanks for your answers ! Georg
