Simple Postflop is a solver for calculating Nash-equilibrium (GTO) strategies in preflop and postflop Texas Hold’em situations. It computes GTO strategies based on bet sizing and hand ranges for two players, making it one of the most accurate poker tools. The program supports local computations for PCs of varying power with several algorithms, enabling free GTO calculations on turn and river. It also handles preflop computations via standalone licenses or cloud services. Features include displays of strategies, EV, and equity, plus the ability to fix some strategies. Compatible with NL and FL Hold’em, it runs on Windows and MacOS via virtualization.
