One of the SSDF testers(Bertil) asked me how to change the default setting and I
replied him so I guess that the SSDF used 16 mbytes for chessmaster6000(At least
Bertil did it).

I also remember that the ssdf asked about optimal hash size and they were told
by the programmer that 16 mbytes are best
