Frequently Asked Questions

What does GTO mean in poker?

GTO stands for Game Theory Optimal. It refers to a strategy that cannot be exploited by any opponent — a Nash Equilibrium where no player can improve their result by unilaterally changing their strategy.

Do you need a solver to play GTO poker?

You do not need a solver to understand GTO concepts, but solvers are the primary tool professionals use to study GTO strategies. Popular solvers include PioSOLVER, GTO+, and Simple Postflop.

Is GTO the best poker strategy?

GTO is the most theoretically sound strategy, but exploitative play — deviating from GTO to take advantage of specific opponent tendencies — is often more profitable against weaker players.
