Exploitability
How far a strategy is from equilibrium, measured by the gain available to a best response in the solved game.

- What it means
- Exploitability measures how much the solved strategies can still be exploited by best responses under the solver's game and convention. It is a convergence measure, not a guarantee about a real opponent.
- How it is calculated
- The flop summaries report the solver's exploitability as a percentage of the starting pot. The measurement applies to the configured ranges and action menu.
- Worked example
- For a 5.5 big blind starting pot, 0.7% of pot is 0.0385 big blinds. This describes solver convergence in that game; it does not make every displayed frequency accurate to 0.7 percentage points.
- Why it matters
- A smaller figure means a closer solve within the model. It does not remove error from using different ranges, stacks or bet sizes in practice.
