Consider the following game. Player 1 begins by choosing between l and r. Player 2 observes the choice by player 1. If player 1 has chosen l, then player 2 chooses between A,B, and C. These choices lead to payoffs for player 1 and 2, respectively, of (3,3), (1,0), and (2,5). If player 1 chooses r, then player 2 chooses between a and b. These choices lead to payoffs for player 1 and 2, respectively, of (4,2) and (0,0).
