buy both sides in order to reach the best situation for both.
Here, Neil will probably initially chose strategy 1 in order to avoid loss, but he won’t be able to gain anything though. Bob would probably choose to maximize his payoffs expectations by choosing the first strategy. Finally, neither Bob nor Neil will get payoffs, so that we obtain a Loose/Loose result, which is not acceptable.
They both have to promise to choose the second strategy in order to win.
