SB open range at 12 bb (4-max)
When you're SB and it folds to you, with an effective stack of 12 bb in a 4-max tournament, the solver plays 78.8% of its hands (limp 34.5%, raise 2.00 bb 2.2%, all-in 42.2%) and folds 21.2%. These frequencies come from Exploit It's full preflop tree: a chip-EV equilibrium with antes, computed for every position at the table.
Each cell: the share of each action for that hand, left to right. Gray cell: hand not in the range at this point.
