CO open range at 8 bb (9-max)
When you're CO and it folds to you, with an effective stack of 8 bb in a 9-max tournament, the solver plays 35.5% of its hands (raise 2.00 bb 0.6%, all-in 34.9%) and folds 64.5%. 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.
Key takeaways for this spot
- The solver plays 35.5% of the hands that reach this spot, about 470 combos out of 1,326.
- All-in is the main action for 35.4% of hands: from AA down to 76s, the weakest hand played this way.
- Conversely, the solver plays hands ranked outside the top 100, such as 86s, 76s.
