Review title: pothole
Product review: This is a very preliminary reaction. Got to page 5. Decided to check referenced "prisoners dilemma" on pg 341. My dilemma is why does "you" wind up with two 10yr options while "him" does not get any. They both are shown with equal 3yr and 1yr options. Is that what is meant by a non-zero-sum?
