How this data is built

Ranges of the GG Poker NL10 to NL50 regular-player pool, reconstructed from millions of real hand histories. Action frequencies are observed directly; the composition of each range is corrected for showdown bias with inverse probability weighting and Bayesian estimation with GTO priors. Data window: Rolling two years, hands up to June 2026. Last reprocessing: . Pool: Regulars (VPIP up to 34, VPIP minus PFR up to 9 points), 100 to 150 bb effective. Sample threshold: Dynamic per spot; nodes below it are not published.
