   The box I have brags that they took Chessmaster 2000, added 10 man years of
   work... that Fidelity Electronics is the "developers of the world's Only USCF
   Certified Master Rated (2325) Chess Program!!!" ...

   Lots of doubletalk and impress-me phrases, but nothing solid about the end
   product itself.  <sigh>

International Master Larry Kaufman  estimates it would take a 33mhz
386 with zero wait state to run on before Chessmaster 2100 would play
at the 2100 level. On an XT, he says its something like 1750!

The story of the Chessmaster 2100 box rating of 2325 is complicated.
Originally Fidelity, in the form of programmers Dan and Kathe Spracklen,
had a good program called the Mach 3 which achieved a 2265 rating 
on a 68000 and a 2325 rating on a 68020. Software Toolworks, the
authors of the  Chessmaster 2100 program, bought out, purchased, or got
rights to the 2325 program for purposes of running it on a different
(Intel) architecture. The port was done, but just about everyone I
know, and Larry all feel the Chessmaster 2100 program is no where near
as strong as the Mach 3 on a 680020 (called the Mach 4).

I'll take a moment to plug a program called "M Chess". It is an IBM
(Intel) based program. But its forebears (earlier versions of the same
code) managed to defeat IM John Grefe in across the board tournament
time control play, and achieve a 2500+ performance rating over a short
series of games at the U.S. Amateur Team last year (all of the above
while running on a 386 chip under DOS.) Recently M Chess played the
programs Rex (version 2.3) by Kaufman and Zarkov (version 2.05) by
Stanback. These two programs ran on 12mhz 386's while M Chess was
purposely handicapped to a 4.77mhz XT.  The score was 4w-2d-0l and
4w-0d-0l in M Chess's favor. Also, M Chess played and defeated
Mephisto Polgar which ran on high speed bit-sliced configuration. The
margin was about 3-1. M was running on a 25mhz 486 so both programs
were running on fast hardware.  And a forebear of M defeated Mephisto
Portorose 9.5-6.5 in tests by Larry Kaufman. Against Fidelity Mach
3 at 40/2, the score is 6-0 M's favor. Against Mephisto Mondial,
the score is 3-1, M's favor, etc.

Anyway if you want information about M, contact The Computer Chess
Gazette at 714-770-8532...
