No, nor can I as my last versions of either programs are Deep Fritz 8 and
Shredder 8.
The purpose of these Nunn2 tests has been to compare the playing styles/settings
of Rybka under rigorously identical conditions in order to determine how they
do. So far I have only tested against Deep Fritz 8 and Chess Tiger 15 (chosen
because it had supposedly caused Rybka some problems according to CEGT results)
and the results have been:
Rybka 1.0 "very positional" (default)
vs. Deep Fritz 8 24 - 16
vs. Chess Tiger 15 30.5 - 9.5
vs. Fruit 2.2 25.5 - 14.5
Rybka 1.0 "slightly positional"
vs. Deep Fritz 8 30.5 - 9.5
vs. Chess Tiger 15 29 - 11
vs. Fruit 2.2 next to be tested
No idea which opponent will come after that, but I am open to suggestions.
