What is Equity in Poker

Equity is your real percentage chance to win the hand if all the remaining cards were dealt out. It isn't a hunch or how strong your hand "feels": it's a concrete number that comes from comparing your cards against the opponent's (or against their range of possible hands).

A classic example: you go all-in preflop with A-K against a pair of queens (QQ). Many people think the pair wins easily, but equity says otherwise: the pair of queens wins about 54% and your A-K 46%. It's almost a coin flip. Against a pair of twos, A-K is a true coin flip (~50/50), and against A-Q it dominates at close to 70%.

Why it matters: equity is half of nearly every calling decision. The other half is pot odds. If you have 40% equity to complete your draw but the pot only requires you to win 25% of the time to call, calling is profitable in the long run. If it's the other way around, you fold. Knowing how to estimate your equity is what turns "I think I'm ahead" into "I know this call makes money".
