What is fold equity?
Fold equity is the value you gain from the chance that your opponent folds. A bet can win in two ways: right away when they fold, or at showdown when they call and you have the best hand.
EV = fold% × pot + call% × (equity × final pot − your bet)
Example: the pot is $100 and you shove $100 with a flush draw (35% equity). If your opponent folds 40% of the time, EV = 0.40 × $100 + 0.60 × (0.35 × $300 − $100) = $40 + $3 = +$43.
Break-even fold rates
With no equity at all (a pure bluff), you need your opponent to fold bet ÷ (pot + bet) of the time:
| Bet size | Pure bluff must work |
|---|---|
| Half pot | 33% |
| Two-thirds pot | 40% |
| Pot | 50% |
| 2x pot | 67% |
Any equity you have when called lowers that number, which is why semi-bluffs with strong draws are so profitable.
FAQ
How do I estimate how often someone folds?
Start with their tendencies: tight players fold more, calling stations almost never fold. Then think about the board and the story your bet tells. When unsure, test a cautious and an optimistic number.
Does fold equity matter in tournaments?
Yes, especially short-stacked. Push/fold charts are built on fold equity plus equity when called.
