No-limit hold'em (6-max)

The NLHE preflop ranges — v2 endpoints with per-hand EV, plus the legacy v1 tree.

Six-handed no-limit hold'em ranges at stack depths 20, 30, 40, 50, 70, 100, 150, and 200bb, positions UTG, HJ, CO, BTN, SB, BB. Weights are on the 169-grid (AA, AKs, AKo, …), each in [0, 1].

The v2 endpoints additionally return evs — per-hand expected value in small blinds. EV is emitted for every hand the bundle scores, including hands the action is never taken with; that zero-weight EV is what makes "folding AKs here costs 3.2sb" computable.

Operations are published through the GitBook OpenAPI plugin from openapi.yaml.
