MTT preflop strategy

SB range vs CO limp at 12 bb (6-max)

When a recreational player limps from the CO and you're on the SB, with an effective stack of 12 bb in a 6-max tournament, the solver plays 32.9% of its hands (raise 5.00 bb 0.6%, all-in 32.3%) and folds 67.1%. 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.
