Preflop charts
Rail's own reference for No-Limit Hold'em cash — six-handed from 40 to 200 big blinds deep, full ring from 100 to 200 — computed by our solver, never copied from anyone's charts. Pick a table and a spot: every hand shows how often the reference takes each action, and hovering or focusing a hand shows what each action is worth.
A model, with a known weaknessThese charts (charts/4) value a flop with an equity-realisation model fitted to our own postflop solver. The measurement checks the flop, so hands that win through implied odds are still a little under-rated: UTG folds 55–22, 87s–54s and A5s, and the button almost never flats a cutoff open. Grades against playing those hands lean harsh. Limped pots are in: the reference rarely limps itself outside the small blind, so behind a limp it assumes the limper may hold any hand.
