Consider a game with two players: Player A and Player B$.$ Each player starts out with $$10.$ Each

player gets to choose between three strategies: Give $($G$),$ Keep $($K$),$ or Lock $($L$).$ Each strategy

works as follows:

$$ If a player chooses Give, they give up $$1$ of their income, but the other player will receive

an additional $$4.$ They may still receive money from the other player.

$$ If a player chooses Keep, they get to keep all of their money they begin with and they give

$$0$ to the other player. They may still receive money from the other player.

$$ If a player chooses Lock, they get the keep their $$10$ and receive an additional $$1.$

However, if the other player sends them any money, the player who chose Lock will not

receive it$,$ and so the player is guaranteed a payoff of $$11.$
