Value Bet

Also known as: value bet, value betting, betting for value

A bet made expecting to be called by worse hands more often than better ones, profiting from the opponent's continuing range.

A value bet is a bet you want called: it's profitable because the portion of the opponent's continuing range that you beat outweighs the portion that beats you. The condition is simply that your equity given a call exceeds 50% — you must be ahead of the hands that actually call, not of villain's whole range.

Value betting is the counterweight to bluffing in a balanced range; the two are tied together by the bluff-to-value-ratio at your chosen bet sizing. Thin value bets — getting called by hands only slightly worse — are where edges are won, but they're also where reverse implied odds bite if you misread the calling range. Sizing matters: against a calling station size up, since they call too wide; against a nit, value-bet thinner and smaller because their calling range is strong. Hands strong enough to bet three streets for value also dictate geometric sizing when you want maximum chips in by the river.

Example

River, you hold top pair good kicker; villain's calling range is {worse top pair, second pair, busted draws that bluff-catch}. You beat roughly 65% of what calls a 60% pot bet. Then EV of the value bet ≈ \(0.65\times(\text{bet won}) - 0.35\times(\text{bet lost})\); with a 60 bet that's \(0.65\times60 - 0.35\times60 = +18\) per call — a clear thin value bet, sized to keep their worse hands in.
