By Thoralf Karlsson, thoralf.karlsson@mailbox.swipnet.se, Chairman of the SSDF
Last year Stefan Meyer-Kahlens program Shredder became the official World Microcomputer Chess Champion in Jakarta. Now SSDF has got the opportunity to play with Shredder against other chess programs in order to measure its playing strength. After 144 games Shredder 1.0 Pentium 90 MHz has received a rating of 2391.
Shredder 1.0 P90 has 78 points less than the best program on Pentium 90 MHz and is about as strong as Junior 4.0 and Nimzo 3.5. Only five programmers have a program which is rated higher than Shredder 1.0. Soon an improved version of Shredder will appear and hopefully we will get the possibility to play with it also.
Ed Schröder has made a new and slightly stronger version of his program. On Pentium MMX 200 MHz Rebel 9.0 has received 29 points more than its predecessor and on Pentium 90 MHz the difference is 14 points. This gives a first place among the programs tested on P90 and a second place on P200 MMX!
On the faster hardware Rebel 9.0 has only one point less than the leading Hiarcs 6.0! Rebel 9.0 P90 has eleven points more than Hiarcs 6.0 on the same hardware. The correct conclusion is that the two programs are equally strong when played againstother chess programs.
Rebel 9.0 and Shredder 1.0 will be the last programs tested on Pentium 90 MHz. In the nearest future only Pentium MMX 200 MHz will be used. So far the average difference between the two hardwares is 76 points.
We have started to play with Fritz 5.0 and we have also received the programs MChess Pro 7.0 and Nimzo '98. This will keep us busy for at least a couple of months. Next ordinary list will appear late January.
