SB open range at 12 bb (9-max)
When you're SB and it folds to you, with an effective stack of 12 bb in a 9-max tournament, the solver plays 83.8% of its hands (limp 32.7%, all-in 50.9%) and folds 16.2%. 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.
