Ubi Soft claims that Chessmaster is "The World's Most Popular
Chess Program"! I don't know if that is correct or not, but it
could be, in some sense. Among the testers of SSDF though, the
Chessmaster programs are certainly not the most popular in the
sense frequently tested. Why is it so? With all other commercially
available chess programs that we have come across for many years, it's
easily possible to play long series of games against other programs
automatically, 24 hours a day. But not with Chessmaster!
Well, it's possible to do it with another programs interface, opening
book and learning function, but we eventually came to the conclusion that
this method wasn't fair... Instead some of us have managed to play one game
at a time automatically with Chessmaster 9000 Athlon 1200 MHz, using
winboard232. After 376 games Johan de Konings program has received
a rating of 2718! That is roughly 120 points more than the estimated
rating of CM8000 on the same hardware!!
When testing CM9000 we have used the original program (version 1.0.0),
under it's original interface with it's own opening book, which doesn't
have any learning function. The hashtables have been set to 64MB.
Another new entrant from a computer chess veteran is Ed Schröders Rebel 12
Athlon 1200 MHz. This Windows(!)-program is running under the Chess Partner-
interface and has the version number 12.00.01. After 382 games it has a
rating of 2691, which is 17 points more than Rebel Century 4.0 has.
A completely new entry on the SSDF Rating list is Deep Sjeng 1.5a Athlon
1200 MHz, also running under the Chess Partner interface. The program is
written by Gian-Carlo Pascutto and the opening book is made by Jeroen Noomen.
Deep Sjeng supports up to eight processors. When tested on one it's rating
is 2670!
About a year ago Ruffian 1.0.1 entered the rating list as the strongest freeware
program. Now Per-Ola Valfridssons program has become commercially available,
running under the Arena Chess GUI written by Martin Blume and with an opening
book from Djordje Vidanovic. After 151 games Ruffian 2.0.0 A1200 has 2611, which
is 67 points less than version 1.0.1 has. February 24 two new versions of
Ruffian 2 became available, and we will play with either of them instead,
hopefully with better results than with version 2.0.0.
Nowadays very few new chess computers are included in the SSDF rating list.
Thanks to Schach Niggemann we've got the possibility to test Novag's Star
Sapphire, written by Dave Kittinger. After 103 games Star Sapphire's rating is
2029, 21 point more than it's predecessor Sapphire II has.
We have now started to test Deep Fritz 8.0 and will later play with a new
version of Ruffian 2 and with Shredder 8.0.
