Mixed strategy
A strategy that takes more than one action with the same hand, each at its own frequency.

- What it means
- In a mixed strategy the same hand is sometimes raised and sometimes called or folded. At equilibrium, every action that is mixed has the same EV.
- How it is calculated
- Solvers mix a hand when its actions are close to equal in EV and mixing keeps the overall range balanced.
- Worked example
- Suppose a hand raises 60% and calls 40%, and both actions are worth +0.8bb. Either choice loses 0bb, even though raising is the more common one.
- Why it matters
- Mixed spots are why a low-frequency action can still grade as Best when EV data exists. Only frequency-graded spots penalize the rarer choice.
