Jean Jacques Rousseau suggested the following puzzle in 1755:

Back in the Middle Ages you and three other hunters set off into a valley where a stag has been sighted. As you walk along, the oldest hunter points out that one person cannot kill a stag alone, so he suggests that each man take a corner of the forest and wait in silence. If anyone spots a stag, drive it toward the river where all can bring it down and come home with food for ten meals. During the day each man might see a rabbit run by, easy to bag and good for one meal.  But if anyone leaves his watch, he says, the stag will get away through that corner of the forest and all the other hunters who stayed at their posts will get nothing.

You will be honorable, of course, and hold your position. But what if one of the other hunters gets an opportunity and takes off? Should you agree to this deal? What is the best strategy?
