In the world of poker, players often find themselves navigating a fine line between strategic play based on mathematical models and decisions influenced by biological and emotional factors. While it is tempting to focus on interpersonal dynamics and risk-seeking behavior, research has shown that Game Theory Optimal (GTO) strategies are not dependent on opponent modeling. This essay explores the importance of maintaining a clear distinction between playing poker as a strategic game and engaging in a social learning process driven by biological and emotional factors.

Mathematical Foundations
- Game Theory: Poker is fundamentally a game of imperfect information, and optimal play can be derived from principles of game theory (Kuhn, H.W. Lectures on the Theory of Games. (Princeton University Press, 2003)). A key concept is the Nash equilibrium, where no player can improve their expected value by unilaterally changing their strategy.
- GTO Strategies: GTO strategies are designed to be unexploitable. They ensure that a player's decisions are based on mathematical probabilities and pot odds rather than emotional or biological factors.

Independence from Opponent Modeling
- Research Findings: Billings et al. (2002) and Bowling et al. (2015) have demonstrated that GTO strategies do not depend on opponent modeling. These studies show that optimal play can be achieved without considering the specific behavior of opponents.

Emotional Drivers
- Risk-Seeking Behavior: Players often make decisions influenced by emotional states such as overconfidence, fear, and excitement (Reese, 2016). These emotional drivers can lead to deviations from optimal play.
- Biological Factors: Gender-based differences in risk tolerance have been observed, with male players generally being more aggressive and female players more cautious (Kraus, 2019).
-
Social Learning Process
- Human Bias: The human bias to focus on opponent behavior is understandable due to our evolutionary history as social animals. Interacting with others provides rewarding stimuli, which can make it tempting to build an opponent model during the learning process.
- Exploratory Nature: During the learning phase, players often engage in random and exploratory behavior. This process of "playing with the player" is a natural part of exploring poker but is not the optimal way to play the game.
- Playing vs. Learning: The statement "in poker you play with cards, but learn with players" accurately reflects the nature of what happens when people engage in the game. While building an opponent model can be a useful learning tool, it is not the essence of playing poker optimally.
- GTO as the Goal: The goal of optimal poker strategy is to achieve GTO play, which does not depend on opponent modeling. This means that while interacting with opponents can help in understanding the game, it should not be the primary focus during actual gameplay.
In summary, playing poker optimally involves adhering to GTO strategies, which are independent of opponent models. While building an opponent model can be a valuable part of the learning process, it is important to distinguish between this exploratory phase and the strategic execution required for optimal play. The correct statement should be: "in poker you play with cards, but learn with players." This distinction helps in understanding the nature of what happens when people engage in the game and emphasizes the importance of mathematical and strategic thinking over emotional and social interactions.
