fold equity

Alice holds A♣6♥. Brian holds 2♥2♦. Flop: 9♠7♣3♦. If there's no more betting, the pot equity at showdown is: Alice = 31.5%, Brian = 68.5%. But, if Alice bets and Brian is 70% likely to fold, then Alice's fold equity is 70% × 68.5% = 48.2925%. Total pot equity if Alice bets = 31.5% + 48.2925% = 79.7925%.
