My point about the rational process stands even in a once-off
relationship. The one-off relationship is not, I would think,
zero-sum. It could be, but the issues stand outside of whether it's a
zero-sum game. They're just more obvious when total jail time served is
less in years if both players keep silent. If both keep silent and get
two years, that's better than if one defects - total time is ten years
(just for the other person) or if both defect and get three years (total
time = six years).

But did you know the technique that beat Tit-for-Tat? For the
