Half-weight offsuit ace-king
AKo:50 retains each legal offsuit combination at half weight rather than deleting an arbitrary half.
Poker Range Equity Calculator
Compare weighted Texas Hold’em ranges using familiar notation such as QQ+, AKs, A5s-A2s, and percentage weights. The poker range equity calculator expands concrete combinations, removes collisions, and samples legal matchups with a reproducible seed.
Weighted range versus range equity
A complete river board is exact. Flop and turn enumerate exactly within a 100,000-state local budget; larger workloads and preflop use seeded joint-weight simulation after collisions are removed.
Scope: heads-up Texas Hold’em range versus range only. Fixed-hand-versus-range, Short Deck, Omaha, and multiway calculations are not supported.
The slider replaces the range with the top N classes ordered by this site's seeded equity-vs-random benchmark; it is not an opening-range recommendation. Grid clicks and valid text notation stay synchronized.

How the result is built
A Hand Class Represents Multiple Card Combinations
Pair, suited, and offsuit labels expand to physical two-card combinations. A known ace of spades removes every combination containing that exact card.
Known blocker
PairSuitedOffsuit
| Hand class | Before blocker | After A-spades blocker | Removed |
|---|---|---|---|
| AA | 6 | 3 | 3 |
| AKs | 4 | 3 | 1 |
| AKo | 12 | 9 | 3 |
Classes expand into physical combinations
A pair has six suit combinations, a suited non-pair has four, and an offsuit non-pair has twelve. Weights scale effective combinations without inventing fractional physical cards.
Blockers change the sampled range
A board card or card selected by the other sampled hand removes every conflicting combination. Sampling therefore occurs after collision checks, not from two independent class labels.
Interpreting range equity
The result averages across the specified weights and random boards. It is not a solver strategy: position, bet sizing, folds, and range construction remain outside this showdown model.
Worked examples
Board blocker
An ace on the board removes all combinations containing that exact ace, reducing but not erasing ace-heavy classes.
Frequently asked questions
What does QQ+ include?
Queens, kings, and aces as pocket pairs.
Can overlapping tokens exceed 100% weight?
No. Duplicate concrete combinations use the highest stated weight, capped at 100%.
Why do raw and unblocked combo counts differ?
Board cards and the opposing sampled hand make some combinations impossible.
Can the simulation be repeated?
Yes. Preserve both ranges, board, iterations, and seed.
