ii. In contrast, the 'Nash' profile can be a Nash equilibrium. To show this-and find conditions under which it is Nash-proceed as follows: A. In each stage, player 1 has only one deviation: playing D. Calculate the change in player 1's continuation payoff (relative to playing as prescribed by the 'Nash' profile) if she deviates to playing D in one particular round. Under what condi- tions on the parameters would this deviation be beneficial
