What is Game Theory Optimal (GTO) in poker?

Game Theory Optimal (GTO) represents a theoretically perfect poker strategy that, when executed, cannot be exploited by any opponent. It involves balancing different actions (betting, checking, raising, folding) with specific frequencies to achieve a Nash equilibrium, ensuring no player can improve their expected value by unilaterally changing their strategy. While a purely GTO approach is challenging to implement perfectly in practice, it serves as a foundational framework for understanding sound poker strategy and developing balanced ranges. Deviating from GTO can be profitable against exploitable opponents, but understanding its principles provides a strong baseline for robust play.

A GTO player will have a balanced bluffing frequency on the river, making it difficult for opponents to exploit their betting patterns.
