Hi

I just wondered if there was any chessprograms that could use really big
hashtables, i got 2gigs of ram and i dont know any program that can use this
amount. The highest that I know of is Chessbase progs with approx 818Megs or
something close.

If I understand it correctly there shouldnt be any real strength improvement
when I use really big hashtables, but is the strength improvement approximating
some limit, for hashtable-size inreasing towards infinity ??

i will try here to draw with chars what i mean:

elo
xxx| - - - - - - - - - - - - - - -
   |             x   xxxxxx
100|        x
   |     x
 50|   x
   | x
 10|x
   +------------------------------- tablesize in megs, kbytes ....... whatever
     10  100  1000 10000 100000  +oo

Please dont comment my artful chart :)

With Regards
Kim
