Game Theory Optimal (GTO) poker is a strategy that aims to make your play as unexploitable as possible. By adopting this approach, you can ensure that even the most skilled opponents will struggle to gain an edge against you. 

With the rise of GTO solvers, players can now fine-tune their decision-making and elevate their game to new heights. In this blog post, we will explore the concept of GTO poker, dive into the workings of GTO solvers, and discuss their impact on the poker landscape.

The Basics of GTO Poker

GTO poker is a strategic approach based on game theory, a branch of mathematics that deals with the analysis of competitive situations. By applying game theory principles to poker, players can determine the optimal strategy for each situation, balancing their range of hands to ensure that they are as difficult to exploit as possible.

The fundamental principle of GTO poker is to achieve a Nash equilibrium, a state where no player can gain an advantage by deviating from their current strategy. In other words, when all players are playing GTO, no one can improve their win rate by changing their strategy.

This doesn't mean that a GTO player will always win every hand; rather, it means that over the long term, they will maximize their expected value (EV). In practice, GTO poker is about balancing various factors, including hand strength, position, and bet sizing, to make it difficult for opponents to exploit any leaks in your game.

The Role of GTO Solvers

GTO solvers are advanced software tools that help players analyze and perfect their GTO strategy. They use complex algorithms to simulate countless poker hands, taking into account variables such as stack sizes, position, and hand ranges. Based on these simulations, the solver calculates the optimal strategy for each situation, providing players with invaluable insights into the most profitable lines of play.

Here's a breakdown of how GTO solvers work in poker:

Input the parameters: First, the user inputs the relevant parameters for a specific poker situation. These include the number of players, stack sizes, position, and the current betting action.

Define hand ranges: Next, the user assigns hand ranges for each player involved in the hand. This is a crucial step, as the accuracy of the solver's output depends on the accuracy of the inputted ranges.

Run the simulation: The solver then uses its algorithm to simulate millions of poker hands based on the inputted parameters and hand ranges. It explores various lines of play and calculates the expected value of each decision.

Analyze the results: Once the simulation is complete, the solver generates an output that details the optimal strategy for the given situation. This can include recommendations on bet sizing, hand selection, and bluffing frequencies.

Adjust and iterate: Players can use the solver's output to refine their strategy, adjusting their hand ranges and decision-making to better match the GTO recommendations. By repeating this process, players can continually improve their game and work towards mastering GTO poker.

Benefits of Using GTO Solvers

GTO solvers have revolutionized the way poker players study and improve their game. Here are some of the main benefits of using GTO solvers in poker:

In-depth strategic analysis: GTO solvers provide a level of strategic analysis that is unparalleled by traditional study methods. By simulating millions of hands, solvers can identify the most profitable lines of play, even in complex situations that are difficult to analyze through manual calculations.

Objective decision-making: GTO solvers remove emotion and subjectivity from the decision-making process, helping players make more rational choices based on mathematical principles.

Adaptability: As poker evolves and players become more skilled, GTO solvers can help you stay ahead of the curve. By continually adjusting and refining your strategy, you can ensure that your game remains unexploitable and competitive in the long term.

Customizable learning: GTO solvers allow you to focus on specific areas of your game that need improvement. By inputting different parameters and hand ranges, you can target particular situations and gain insights into how to play optimally in those scenarios.

Reducing leaks: By identifying suboptimal lines of play and providing GTO-based recommendations, solvers can help you eliminate leaks from your game, making you a more difficult opponent to exploit.

Limitations and Considerations 

While GTO solvers have undeniable benefits, it's essential to recognize their limitations and the factors to consider when using them:

Solver accuracy: The accuracy of a GTO solver's output depends on the accuracy of the inputted parameters and hand ranges. If these are not accurate, the solver's recommendations may not be optimal.

Complexity: GTO solvers can be challenging to understand and utilize effectively, especially for novice players. It's essential to have a strong foundation in poker theory before delving into the world of GTO solvers.

Exploitative play: While GTO poker is an unexploitable strategy, it's not always the most profitable approach, especially against weaker opponents. In some cases, deviating from GTO to exploit an opponent's specific weaknesses can yield a higher win rate.

Time investment: Mastering GTO poker using solvers requires a significant time commitment. Players must be willing to dedicate time to studying solver outputs and refining their strategy.

Cost: GTO solvers can be expensive, with some of the more advanced software options carrying a hefty price tag. Players must weigh the potential benefits against the financial investment required to use these tools.


GTO poker represents the pinnacle of strategic decision-making in the game. By leveraging GTO solvers, players can refine their strategy and make themselves virtually unexploitable. However, it's important to recognize the limitations of these tools and use them in conjunction with other learning methods, such as hand reviews, coaching, and exploitative play.

By understanding the principles of GTO poker and incorporating the insights gained from GTO solvers, you can elevate your game to new heights and increase your chances of success at the tables. While the journey to mastering GTO poker may be challenging, the rewards can be well worth the effort.

I've been immersed in the world of poker since 2003. Poker is hard. It has undoubtedly been a roller coaster of experiences for me over the years. My poker journey spans from playing at .01/.02 NL tables to engaging in intense sessions at $5/$10. Poker isn't just a game to me—it's a passion. Outmaneuvering opponents in this test of mental strength and strategy offers an unparalleled thrill. To deepen my understanding of the game and to assist others, I initiated this blog. It aims to elucidate the ever-evolving technologies, strategies, and legal landscapes of poker, especially in the online realm. We're now in the age of solvers, but both online and live poker continue to thrive. A quick visit to a local $1/3 game would be ample evidence of its vitality. Regardless of your proficiency level, from novice to expert, I hope my blog posts offer you valuable insights. Feel free to engage with me through messages or by commenting on my posts. Cheers!
