Not with Rybka, I'm mainly using Shredder where it seems to
work pretty well.

I see this when I use it for analysis. It settles quite
quickly for a move, indeed. However, I do not currently see
this in Scid.

Thats sad, indeed, rendering this funcition unusable.

What do you call your "testing group"?

Hm. However they beat a 3000 ELO engine...

I agree. As far as I understood Pascal, however, it is not
trivial to have both protocols supported in the playing
mode. :(

BTW: Did you get ProDeo running on Linux? I admit that I
never really succeeded with the setup. (In case we could
discuss this in PM, if you prefer in german as well ;)
