John von Neuman gave us the Mathematical game theory using the poker asthe model. However, this was only limited to 2 players. This is where linear programming solutions came in, which increased the capability of defeating even the smartest world-class players.

Knowing the game theory or the linear programming solutions for the poker game is not that important unless you are aiming to be like a computer. By the time you are playing, you will not have the luxury of time to be applying the such theory. For novice players, the advice professional players will give you is that you have to know when to bet, when go all-in, when to raise, when to call, or when to fold. But while learning this, get back to your old high school notes and review the concept of probability. Knowing when to get a good hand will guide you to your victory.
