GTO & GTO+

The GTO baseline

GTO (game-theory optimal) strategy is the unexploitable equilibrium: if you played it perfectly, no opponent adjustment could beat you in the long run. Pokercat serves it from a pre-solved library rather than solving live, which is what keeps answers near-instant at the table.

Coverage	Brief
Formats	Cash, MTT and SnG structures — 30+ game formats in total, including heads-up and multi-handed tables.
Stack depths	Solutions are keyed by effective stacks, so short-stack MTT spots and deep cash spots get different answers.
Streets	Full preflop ranges plus postflop solutions street by street.

Note

No library covers everything. When a spot falls outside coverage (for example certain multiway pots), pure GTO mode shows no answer, while Auto mode hands the spot to your selected LLM instead.

GTO+

Equilibrium is a defensive concept — real opponents have leaks, and playing exactly GTO leaves money on the table against them. GTO+ keeps the GTO engine underneath and applies a shift to the returned strategy: frequencies move toward the more profitable line against the tendencies of the opponent type you assigned.

• The shift is anchored to the equilibrium answer, so it stays disciplined — you deviate, but from a solid baseline.
• The direction and size of the shift come from the opponent profile you set for the villain in the hand.
• With no profile assigned, GTO+ behaves like plain GTO.

Tip

GTO+ is the recommended default for live play against weaker fields. If you want the maximum deviation instead of a measured shift, that is what the Exploit engine is being built for.

Quality: how close to NASH?

The library’s average NASH distance is 0.3% — meaning a best-response opponent could win at most 0.3% of the pot more than against a perfect equilibrium. In practice that gap is far smaller than the error introduced by human execution, so the baseline is effectively unexploitable at any stake Pokercat targets.
