Chairman of the SSDF
One of the weaker PC programs on our rating list is Nimzo 2.2.1, which entered the list two years ago. Since then Nimzo's author Chrilly Donninger has among other things made the AUTO232 system, which has been of great value for SSDF's testwork. Earlier this year we heard rumours about a new version of Nimzo, but nothing was said about its strength.
The excellent result for Nimzo 3 in the Aegon tournament together with advertisement statements increased our eagerness to test it. During the last 3-4 weeks we have played 321 tournament games with Nimzo 3 Pentium 90 MHz, which now has a rating of 2380! Compared to Donninger's earlier version, the increase in program strength is about 250 points!! We congratulate Chrilly and the team around him!
In the top of the list there are now programs of five programmers within a range of 41 points, and one among them is Nimzo 3. And soon after them comes Fritz 3, Kallisto 1.98 and WChess 1.06. Marty Hirsch's MChess Pro 5.0 is still leading, but only with one single point ahead of Genius 3.0. It's clear that there are many programs which have a chance to win the coming Micro World Championship in Jakarta!
A completely new program on this list is Comet32 9.9 Pentium 90 MHz with a rating of 2225. The name of the author is Ulrich Türke, from Germany. Comet32 is a amateur program, partly based on GNU-chess.
The freeware program Rebel Decade has lost as much as 31 points since the last list. Now it has "only" 2263, but this is still clearly higher than Schröder's estimation.
We have only managed to play 49 additional manual games with Fritz 4.0 P90. It's rating has gone up two points to 2287, which still is 76 points worse than for Fritz 3.0 P90.
Another new program which we also have to play manually with is CM5000 for Windows 95, written by Johan de Koning. This means that it will take several months before it appears on the rating list. With the high rating for R30 v.2.5 in mind, it is possible that CM5000 on P90 could take one of the highest positions on the list.
In September Rebel 8.0 is expected to appear. This new program from Ed Schröder will be one of the contestants for the first place on the rating list.
