Let’s Begin…

Two perfectly rational gingerbread men, Crispy and Chewy, are out strolling when they’re caught by a fox. Instead of simply eating them, he decides to put their friendship to the test with a cruel dilemma. He’ll ask each gingerbread man whether he’d opt to Spare or Sacrifice the other. What should they choose? Lucas Husted dives into the classic game theory scenario: the Prisoner's Dilemma.

Here we assumed that the game was infinitely repeated. Ignoring discounting, Is it possible to come up with an example where the players agree to cooperate based on the game illustrated here if they had played it 3 times in a row instead of infinite times? How about 10 times? What leads to the result you find? (Hint: try to reason backwards).
