So let's begin by consdiering the case where player 2 plays C If player 2 plays c, then player 1 is really thinking about this.

If you eliminate weakly dominated strategies from a game, an equilibrium in that simplified game will be an equilibrium in the original game as well. However, this process may delete other equilibria from the game. Unfortunately, there is no way of knowing whether you have removed any equilibria, so you must go back to the original game and.

Confessing is a dominant strategy for Johnny as well. A game in which there is a dominant strategy for each player is called a dominant strategy equilibrium. Here, the dominant strategy equilibrium is for both prisoners to confess; the payoff will be given by cell A in the payoff matrix.
