SB open range at 20 bb (heads-up)
When you're first to act in the SB, with an effective stack of 20 bb in a heads-up tournament, the solver plays 89.3% of its hands (limp 68.6%, raise 2.00 bb 13.6%, all-in 7.0%) and folds 10.7%. 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.
