MChess Pro 5.0 Pentium 90 MHz has lost eleven points since the last rating list in November, but it still holds the first place of the list! After nearly 500 games, the difference between the programs of Marty Hirsch and Richard Lang is now only twelve points, clearly within the margin of error.
In the future we probably cannot continue with the "luxury" of testing new programs on both Pentium and 486. But with MChess Pro 5.0 486/50-66 MHz we have managed to play 317 games, and it's present rating is 2372. Although that is one point below the rating of Rebel 7.0 on the same hardware, it confirms that MChess Pro 5.0 is one of the strongest programs.
During the last weeks we have played with the new Genius 4.0 on Pentium 90 MHz. After 167 games the rating is 2421, which is 14 points less than Genius 3.0 P90 has. Since the margin of error is almost 60, Genius 4.0 could still reach the top of the list, but most likely the difference in playing strength between Lang's two latest programs isn't very large. On the next list we will also include Genius 4.0 on 486/50-66 MHz. Here Genius 4.0 has started better than on P90.
Rebel 7.0 Pentium 90 MHz has gone up seven points since the last list. As before, the difference in rating between Rebel 7 and Rebel 6 is clearly larger on 486 than on Pentium.
Johan de Konings R30 version 2.5 has earned twelve more points and now has 2369. It continues to be the strongest chess computer.
It will probably be possible to include Hiarcs 4.0 P90 on the next list scheduled for February 4.
Many new programs are waiting to be tested. Fritz 4.0 is of course an exciting program to evaluate, but unfortunately we have not received any copies from the manufacturer or the programmer.
A new Kallisto (v2.0) is expected in a few months. That's what we have been told by Mr. Bart Weststraate. Chris Whittington's Chess System Tal is now available, and so is the Danish program Gandalf v2.1 by Steen Suurballe. ChessMaster 5000 is another expected program later this Spring.
But for the next month or so, our priority is to get as many games as possible for Genius 4 and Hiarcs 4.
