Mixed Strategy
Math Level · Advanced Aliases: frequency mixing, mixed actions
A mixed strategy takes two or more legal actions in the same spot, each at a set frequency.
What is Mixed Strategy
A mixed strategy means that with the same information and the same hand combination you do not always take one action, but split between betting, checking, calling, raising or folding at defined frequencies. It makes your overall range harder to attack with a fixed counter-strategy. Mixing is not changing your mind in the moment, and it is not pressing buttons at random. First understand why the actions have near-identical expected value, then execute with suits, a random number or a simple rule. When an opponent has an obvious leak, taking the higher-EV exploitative action usually beats maintaining a theoretical mix.

Example
At a given river node, the same blocker combination bets part of the time and checks the rest. You execute that split with a pre-set randomiser, not according to whether the last hand went well.
Common mistakes
- Assuming a mixed strategy means choosing at random. The frequencies and combinations have strategic reasons; randomisation is only the execution tool.
- Believing every opponent requires a theoretical mix. Against clear over-folding or over-calling, lean straight to the higher-yielding action.
