The answer to this one is simple so I can do the job :) . Whatever you set up in
the hiarcs 7.32 interface as hash won't bother crafty ; if you want
reasonable hash size set it up in Crafty.rc AFAIK ( if the one who ported it did
not some original work which might be possible ); else you will have the default
hash size ; dont' forget to use Mr Hyatt's tip about hash and hashp.

Also if you use two computers I strongly suggest that you use winboard and
crafty16.10 for crafty instead of the CB thing ; you can use book.bin + the
crafty learn function then, and it seems to work faster . You can copy the TBs
from your Hiarcs CD ; you only have to add TBpath to your winboard.ini.

Now something I am not 100 % sure of ; to my experience crafty 16.11 is weaker
than 16.10 , especially in computer games ( little data , only my impression
after watching some games ); 16.10 seems to be _much_ stronger than 16.6.
