ELO performance difference Hiarcs P233MMX - CST PII400: 240
A word of caution: Don't take the resulting rating difference as an absolute
figure, this was just 20 games which implies a certain margin of error.
If you want a "reliable" rating, I would recommend Eric Hallsworth's Selective
Search rating list (http://www.elhchess.demon.co.uk/), where you will find CST
at 2421 on P233MMX (Hiarcs 6 at 2585).
Significant seems to be the fact that CST was unable to win in all but 1 of the
20 games. In my opinion, this messages goes beyond any margin of error and
statistical tricks (don't forget, CST had more than twice as fast hardware as
it's opponent).
Please feel free to comment on the games, if you need them all, I will be happy
to send them to you via email. I also have all CST logfiles, if you want to know
what made it play a particular move, I can also send you these files.
Moritz
P.S.: I have been told here by many friends that I should use the 289 version of
CST (aka black.exe). This version supposedly played much stronger than the one
you can buy in the shops. You should take this into account when you want to
purchase CST based upon my results.
