Introduction to Game Theory/Matching Pennies
In this game we imagine two players, each with a penny. They independently choose a side of the coin and then simultaneously show the other the chosen side. If the sides match, then Player 1 gains Player 2's penny. If the sides differ, Player 2 wins Player 1's penny.
