The good result for Chess Tiger 11.8 on P90 made us very curious about what Christophe Théron's latest program could achieve on faster hardware. Now we know!
After 317 tournament games Chess Tiger 12.0 DOS K6-2 450 MHz has taken the first place on the rating list! It's rating is 2696, which is 25 points more than Fritz 5.32 has on the same hardware! Very impressing!
As can be seen SSDF has played with a DOS-version of Chess Tiger. Will the final commercial Windows-version Rebel-Tiger be slower and therefore weaker? No, surprisingly the opposite seems to be the case! Windows does slow the program down with 2-3%, but since the Windows compiler is better than the DOS-compiler, the net effect is a speed advantage for the Windows version. Our preliminary tests with a beta-version indicates that the Windows version is about 8-10% faster at three minutes per move.
Although we now have many more games with the programs on K6-2 450 MHz than on the September list, the margin of error is still 40-50 points. This must be remembered when the ratings are considered.
The second new program on the list is Chrilly Donningers Nimzo 7.32 K6-2 450 MHz. With a rating of 2663 it takes the third place on the list, 19 points above the predecessor Nimzo 99.
Four out of the six programs on K6-2 450 MHz have also been tested on P200 MMX. The average difference in their ratings is 81 points. Fritz 5.32 has earned most, 97 points, and Hiarcs 7.32 has gained only 64 points.
At the moment we have 8-9 automatic meetings with K6-2 450 MHz. In the near future we would wish to play with Fritz 6.0, Junior 6.0 and Shredder 4.0.
Next list is expected to appear in January.
