## Example

Anna and Ben can either help or leave a village infested by zombies.

Ben decides to Leave. Anna's best response is to Leave as well because a payoff of 3 is better than a payoff of 0.

Ben | |||
---|---|---|---|

Anna |
Help | Leave | |

Help | 2, 1 | 0, 0 | |

Leave | 0, 0 | 3, 2 |

What is Ben's best response if Anna decides to Help?

A payoff of 1 is better than a payoff of 0. Therefore, Help is the best response.

Ben | |||
---|---|---|---|

Anna |
Help | Leave | |

Help | 2, 1 | 0, 0 | |

Leave | 0, 0 | 3, 2 |

Help | 99, 49 | -28, 78 | |
