Range vs Range Equity
Enter two ranges in standard notation and an optional board — get win, tie and lose percentages across every combination. This is the range-versus-range equity real decisions are built on.
How to use it
Enter two ranges. Standard notation: 22+, AKs, ATs+, AJo+, T9s-76s. Use the preset chips to start fast.
Add a board (optional). Up to five cards like 'As Kd 7h' to get equity on that exact texture; blank means preflop.
Run the equity. A Monte-Carlo simulation returns win, tie and lose percentages for Range A.
Because it simulates every matchup between the two ranges over the remaining board, the result is the equity you actually have in the spot — not a single-hand snapshot. That's the number behind sound betting, bluff-catching and all-in decisions.
Range notation cheat sheet
Pairs: QQ, 77+ (77 and up), 88-JJ (a band). Suited: AKs, ATs+ (ATs through AKs), A5s-A2s. Offsuit: AJo+, KQo. Connectors: T9s-76s. Combine them with commas: QQ+, AKs, AJs+, KQs, AKo. The parser handles the rest.
Why range vs range is the real question
You almost never know an opponent's exact two cards — you know the range they'd play this way. Assigning that range and measuring your equity against all of it is the core skill of hand reading. Build the ranges with the Range Trainer, practise assigning them in Guess the Range, and read more in the preflop and postflop guides. For a single known matchup, the hand-vs-hand equity calculator gives an exact answer.
From equity to a decision
Equity alone doesn't tell you to bet or fold — you pair it with price. If you hold 55% against a calling range you can value bet; if you have 35% facing a big river bet, compare it to your pot odds. Range-vs-range equity is the input; pot odds, fold equity and ICM turn it into the play.
