Range vs Range Equity

Also known as: range vs range equity, range equity, range-on-range equity, RvR equity

The pot-share one player's whole range has against the opponent's whole range, the foundation of GTO postflop play.

Range vs range equity is the average equity of all your possible hands against all of the opponent's, weighted by combos. It's the right unit for postflop strategy: a solver doesn't play AhKh, it plays your entire range against theirs, and the aggregate equity split is what sets c-bet frequencies and sizes.

It drives two distinct concepts often confused:

A range can have high average equity but no nut advantage (lots of decent hands, no monsters) — that favours small, high-frequency betting. The opposite (polarised, few but huge hands) favours large, low-frequency betting. Reading the full equity distribution, not just the average, is what separates correct sizing from formulaic c-betting.

Key caveat: equity is not the same as equity realization — being out of position or capped means you won't realise your raw share.

Example

On K72 rainbow, the BTN opener's range might hold ~55% equity vs the BB caller's range (range advantage) and far more sets/top-pair-top-kicker (nut advantage). That combination justifies a high-frequency small c-bet; the BB, holding neither edge, mostly check-defends rather than donk-betting.
