Yep, I should have read the code before answering. When playing on an
external socket, gnubg is using the Evaluation settings. Go to
Settings->Evaluation and add noise there. I assumed, wrongly, that it
used the player0 settings. Probably it should do so, using the
Evaluation settings (normally used just for hints), seems
not-intuitive to me.
