We have a new leader of the rating list! Fritz 5.0
P200 MMX has got 2589 after 198 games!! That's
the highest rating ever and 55 points more than
any other entrant has!
Fritz 5 is about 160-170 points stronger than Frans
Morschs earlier program versions! It's an enormous
improvement! Congratulations to Frans Morsch and the
ChessBase team!!
It has been claimed earlier that the results for
Fritz 3 and 4 would have been better if SSDF had had
PCs with larger RAM. For Fritz 5 we have used at least
64 MB RAM. The auto232-version from ChessBase doesn't
work with less RAM... For most games the PowerBook has
been used and for the rest Fritz 5 has played from
the ordinary opening book. In both cases the book has
been on the hard drive in order to enable book learning.
The margin of error for the rating of Fritz 5 is still
about 50 points, so large changes could occur when more
games are played. But since the gap to the other programs
is 55 points and more, it is most likely that Fritz 5 will
keep it's first place for some time. The competitors have
a slight disadvantage since they have to play manually
against Fritz 5 as long as the auto232-version isn't generally
available.
The rating changes for the other programs are rather small,
seven points or less. But a few points can easily change
the order of the programs. Nimzo '98 is now the second
strongest program, followed by Hiarcs 6 and Rebel 9.
MCP 7.1 is now four points ahead of it's predecessor.
We will continue to play with the best programs. Hopefully
new programs will arrive during the next months.
Next rating list will be made mid April.
