BTN range vs CO limp at 40 bb (5-max)
When a recreational player limps from the CO and you're on the BTN, with an effective stack of 40 bb in a 5-max tournament, the solver plays 30.7% of its hands (raise 4.00 bb 30.7%) and folds 69.3%. These frequencies come from Exploit It's full preflop tree: a chip-EV equilibrium with antes, computed for every position at the table. The limper is a typical recreational player: his limping range is assumed (small pairs, suited aces, connectors, weak broadways, about 19% of hands); you and the other players play equilibrium against it, with an isolation raise or an all-in.
Each cell: the share of each action for that hand, left to right. Gray cell: hand not in the range at this point.
