Plain language
A balanced, unexploitable way of playing a game where no opponent can find a weakness to attack.

GTO — a Nash-equilibrium strategy in an imperfect-information game that no counter-strategy can exploit; the target of solver-based poker AI and the benchmark opponent against which PokerSkill agents are measured.
Also called: GTO
