Wheel with a suited five
Choose A-2 in the hand and 3-4-5 of one suit across the board. The key remains [5,4,3,2,1] because flushes and straights do not count against Ace-to-Five low.
Omaha Low Hand Calculator
Find the best Ace-to-Five 8-or-Better low from four, five, or six hole cards. The Omaha Low Hand Calculator identifies the legal 2+3 selection, compares it with the current theoretical nut, and groups every possible next card by its concrete effect.

How an 8-or-Better low is ranked
A legal low uses two hole cards and three board cards with five different ranks, all eight or lower. Ace counts as one. Read the key from highest rank downward: [5,4,3,2,1] beats [6,4,3,2,1], and [6,4,3,2,1] beats [6,5,3,2,1].
Pairs invalidate that candidate, but a straight or flush does not. Therefore a suited wheel remains the best low rather than becoming disqualified as a straight flush. A board needs three distinct low ranks; repeated small cards do not substitute for distinct ranks.
Nut low and shared-nut exposure
The current nut low is found by removing the hero cards and board, then enumerating every legal opponent two-card pair from what remains. If no pair can beat the hero key, the result marks Nut Low. This definition does not promise an exclusive win.
Another player may form the same key with different suits. The Omaha Low Hand Calculator reports shared-nut risk and the number of remaining pairs that can match the theoretical best. Shared low can lead to quartering when someone else wins high.
Concrete counterfeit and next-card groups
On a flop or turn, every unseen card is appended once and the hero low plus theoretical nut are recalculated. Cards are grouped as improves, unchanged, worsens, loses qualification, creates low, or increases shared-nut risk. The displayed SVG cards make the classification auditable.
Counterfeit risk is contextual rather than a single universal percentage. A board-pairing card may damage one route but expose a backup pair from a five- or six-card holding. The analysis always uses the selected hole-count model.
Purpose and boundaries
This is a low analysis tool, not a claim about a standardized low-only PLO game. It supports only Ace-to-Five with an eight qualifier. Deuce-to-Seven, Badugi, and no-qualifier variants are deliberately absent.
Everything runs locally without a hand-history upload or remote API. The result describes visible cards and legal opponent pairs, not betting action, hidden strategic ranges, or a guaranteed pot share.
Worked examples
Repeated board rank
Use a board containing 8-8-5-K-2. Three distinct low board ranks exist, so a compatible hole pair may qualify even though four board cards are eight or lower.
Frequently asked questions
Why does a pair disqualify a low?
Ace-to-Five low requires five distinct ranks. Any duplicated rank makes that particular five-card candidate invalid.
Do straights and flushes count against a low?
No. Only distinct rank values and the eight-or-lower qualifier decide this low.
What is the nut low?
It is the strongest qualifying low possible against any legal remaining opponent pair on the current board.
Can two players share the nut low?
Yes. Different suits can produce the same five-rank key, so nut status does not imply an exclusive low win.
What is counterfeit risk?
Here it means a next board card worsens or removes the hero low, or makes an equal or better opponent low easier to form.
