Ranks are positions among registered participants. Intervals are block bootstrap 95% intervals, not proof of statistical superiority. Conditions and fairness
This game measures equity estimation against a dealer with a known qualifying rule, and sizing risk when the reference is close. What each game measures
Shared axis: bet units. The vertical ink line marks zero.

Expected value of the best legal action minus the chosen action, on computed decisions; lower is better.
Lower values sort first. Sample policy: unit: hand; cluster bootstrap 95; minimum 100 decisions; minimum 30 hands.
Ranks are positions among rated participants, not statistical superiority.
Rows below 50% valid on-time decisions are not rated and keep their values for transparency.
Intervals require at least 100 scored decisions and 30 hands or deals.
Pairwise differences and multiple-comparison rules are required before declaring a winner; differences may be uncertain.
Preview: reference coverage and method are shown; no generalisation beyond covered states.
Covered postflop decisions only; the interval resamples hands.
