What exactly is a preflop chart and why should I care?

A preflop chart is a color-coded grid that tells you which hands to raise, call, or fold before the flop. It removes guesswork, speeds up decisions, and keeps your preflop strategy high EV.

How are the Preflop Prodigy charts built? How do I know they’re accurate?

We used high-performance servers and ran advanced GTO solvers for every position, stack size, and spot you’ll face. We then cross-checked the outputs from multiple runs and tweaked the ranges as necessary to ensure that they’re relatively easy to execute in-game and rock-solid.

We turn that data into easy-to-read charts inside the app. The result: solver-pure ranges you can trust at the table.

We have some published on our charts page.
