In the first two classes we consider a few games with easy rules (can be explained in 5 minutes).

Here is Mother of all games. A player can choose \$1 or \$2.
Solution: the player takes \$2.
If you do not understand this, drop the class.

More generaly, for any one player game, the maximal possible payoff is the value of game and any way to get is is called an optiml strategy.
