Subject: Hash tables and Fritz

I purchased Fritz mainly for analysing games.I now realize Fritz uses a
lot of Hash tables.
My machine: 300hz-64mb ram-1gig hard disc.

According to the users manual HT requirements are:2*proc.speed*no.sec per move.
                                                                      Now what
is the min.time per move in order to obtain a good game anaylsis?
I think 3min's is reasonable.But 2*300*3*60=108,000kb hash.The most I am able
to get,if I don't want the hard disc to whirl forever and the screen to freeze
is 33,000 to 40,000kb.This translates to 1min. approx. per move.Is this enough
for adequate game analysis?

I recently played three games engine vs engine(Crafty/Fritz).When setting the
parameters my machine indicated that only 25,728kb of free ram was available.
when I tried to increase the HT the machine seemed to stall.I guess I shall
have to buy more ram.
By the way Fritz won all three games.


Getting completely off the subject,Crafty 16.3 seems to be a very good program.
Is it a positional player?What is it's Elo?
