CO open range at 15 bb (9-max)
When you're CO and it folds to you, with an effective stack of 15 bb in a 9-max tournament, the solver plays 35.0% of its hands (raise 2.00 bb 23.7%, all-in 11.3%) and folds 65.0%. 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.
