Game Theory 101: The Complete Textbook on Amazon:
What happens when we have a game that doesn’t have any strictly dominated strategies? This video introduces the concept of Nash equilibrium.

This video shows how to find pure strategy Nash equilibria by looking at each individual outcome and checking for profitable deviations.
