Figure 2.
A game tree diagram shows sequential decisions by two players. On the left, a node labelled Player Row branches into two actions labelled A 1 and B 1. Action A 1 leads to a decision node labelled Player Column, which branches into actions A 2 and B 2. Action A 2 leads to a bracketed outcome labelled x 1 comma x 2, and action B 2 leads to a bracketed outcome labelled y 1 comma y 2. Action B 1 from the first node leads to another Player Column node, which branches into actions A 2 and B 2. Action A 2 leads to a bracketed outcome labelled z 1 comma z 2, and action B 2 leads to a bracketed outcome labelled w 1 comma w 2.Extensive form
