Thanks; the Bayesians vs. Barbarians post is exactly the kind of thing I was looking for. I’ll have to read some of the posts that it links to (as well as re-read the background posts you referred to; haven’t read them in a while), as the way it stands I still think the Barbarians would win.
See Bayesians vs. Barbarians. You may need the following posts for the background:
Newcomb’s Problem and Regret of Rationality
Newcomb’s Problem standard positions
The True Prisoner’s Dilemma
