The Semi-Bluff EV calculator estimates the expected value of an all-in semi-bluff in poker. When we semi-bluff, we give ourselves two ways to win a hand. The first is by making our opponent immediately fold, while the second is making the best hand at showdown when we get called. This EV calculation takes both of those scenarios into account, making it a bit more complex than the basic EV calculation:

**Scenario 1**: Hero semi-bluffs, villain folds, and__hero wins__**Scenario 2**: Hero semi-bluffs, villain calls, and__hero wins__**Scenario 3**: Hero semi-bluffs, villain calls, and__hero loses__

Our EV calculation then becomes the following: **Semi-Bluff EV** = (Scenario 1) + (Scenario 2) – (Scenario 3)

**Scenario 1**= (Villain Fold % x Size of Pot)**Scenario 2**= [(Villain Call % x Probability of Winning) x (Size of Pot + Villain Call Amount)]**Scenario 3**= [(Villain Call % x Probability of Losing) x (Semi-Bluff Amount)]

Since this is a quite lengthy EV calculation, we created the Semi-Bluff EV calculator below to calculate the EV of an all-in semi-bluff.

### Semi-Bluff Expected Value (EV)

**Explanation**

The Semi-Bluff EV calculator estimates the expected value of a semi-bluff in poker. It takes into account the likelihood of the villain folding, the probability of winning if called, and the potential gains and losses in each scenario.
