"In conclusion,higher Hashes take time to fill but the strenght
or lines higher Tables is noticable."
Hi Mike
Your are in principle right. The question however remains what is
meant by "noticable". I have so far never seen a reliable test that
proved an increase of playing strength in ELO with higher hash tables.
Personally, I think there is indeed not much difference: it should
at least be 32 MB, perhaps better 64 MB hash but all about these values
will hardly bring anything 'noticeable'. If I find the time or better
if I have nothing better to do, I am going to make a test between two
programs.

This applys to all Chessbase Engines that I
>have (Fritz,Junior,Shredder).Tiger(from Rebel,and NOT under a Chessbase GUI) has a maxium of 192 mb of Hash,and I can't get anymore on any of My P/cs.Shoot Me a E-mail if I can be of futher assistance.
