In most rating lists, Grizzly is around 1800-1900 - this new version is a little
bit stronger, but I doubt that it is over 2000. Does this mean that Chess Tiger
on Palm is also clearly under 2000 ? Or is this another point where
engine-engine matches are very different to engine - human matches ? Anyway, I
would like to see some more matches of Chess Tiger on Palm against the lower
edge of the winboard-engines... And besides that, frequently here are some
postings of games ChessTiger on Palm against some well known dedicated chess
computers which are listed on the SSDF-list. ChessTiger wins many games, does
that mean that those old irons are still overestimated on the SSDF-list. Or
should we finally stop to compare SSDF-ELO with human ELO ? (Which I say for a
long time now - there is no real comparrison... The 100 ELO-penalty for the hole
list was somehow irregular because the old iron often have showed there strength
against humans, so why decrease them 100 ELOs ?)
Greets, Thomas
P.S.: I think a solution for the SSDF would be a completely different rating.
Just stop to make them compareable with human rating and set a starting level
for the lowest listed engine of e.g. 0 or e.g. 10000 so just the numbers are
very different to FIDE-ELO and noone would compare anymore.
