The most common email-question about the SSDF rating
list, has been about the absence of any Chessmaster-
version on K6-2 450 MHz. And the answer has always been:
"Chessmaster can not be played automatically, and none
of the testers are nowadays willing to play manual games."
From now on I expect that the above mentioned question will
cease to arrive! Thanks to a Winboard adapter from Eberhard
Börger, it's now possible to play automatically with
Chessmaster 8000, although only one game at a time. For
unknown reasons it doesn't work for all of the testers, but
at least for a couple of us.
After 191 tournament games Chessmaster 8000 K6-2 450 MHz has
received a rating of 2502. As CM6000 on P200 MMX has 2473, the
present result is clearly a disappointment. Even with no
change of the chess engine, you would have expected about
fifty more points. Due to relatively few games played with
the two Chessmaster versions, statistical reasons could be
a partial explanation. Another possibility is that CM8000 is
a weaker chess program than CM6000.
The most fascinating thing about testing chess programs, is when
you can conclude that a new program is better than it's
predecessor. As could be seen above, this is not always the case.
Therefore I'm glad to say that Christophe Théron has managed
to clearly increase the playing strength of his program during
the latest 18 months!
The Rebel-version of Gambit Tiger 2.0 K6-2 450 MHz has a rating
of 2650 after 302 games!! And Chess Tiger 14.0 K6-2 450 MHz
(sold by ChessBase) got 2632 after 308 games! Compared to CT 12.0
the rating increase is 74 and 56 points! GT2 is only three points
behind the leading Deep Fritz. In average the two Tiger-versions
are twelve points behind. It will be interesting to see what
happens when more games are played.
The fight between Fritz and Tiger will continue, now also on
a higher level! The reason is that SSDF has started to test on
a new hardware, Athlon 1200 MHz with 256MB RAM! After the summer
we expect to present the first results with 5 or 6 of the strongest
programs.
New programs which we expect to test in the near future are
Shredder 5.32, Junior 7.0 and Gandalf 4.32h. If Hiarcs 8.0 arrives
during summer, it will also be included on the next list, which
will appear in late August or early September.
