PLO5 Rules: What Changes With Five Cards

Five-Card Pot-Limit Omaha (PLO5, or “5-card PLO”) has grown quickly online and in live card rooms. The rules are almost identical to four-card Omaha — you just get one more hole card. But that one card has a big effect: every hand has far more ways to connect with the board, showdowns are won by stronger hands, and the difference between the nuts and second-best becomes the most important thing in the game.

Key takeaways

• PLO5 is PLO with five hole cards. You still use exactly two hole cards and three board cards.
• Five cards give ten two-card combinations (PLO4 has six; Hold'em has one).
• Showdowns are won by stronger hands: in six-way pots that reach the river, the winner has a straight or better about 89% of the time.
• Starting-hand equities run even closer than in PLO4.
• Drawing to — and holding — the nuts matters more than in any other common poker game.

What stays the same

• Blinds, positions and betting rounds are the same as Hold’em and PLO4.
• Pot-limit betting — see Pot-Limit Betting.
• The exactly-two rule: your hand is always two hole cards plus three board cards. The traps from PLO Rules all still apply — one heart in your hand never makes a flush, and you can’t play a straight that needs three of your cards.

Because a full table needs more cards, PLO5 is usually played 6-max or smaller.

What changes

More combinations

Game	Hole cards	Two-card combinations per hand
Hold’em	2	1 (and you may use 0, 1 or 2)
PLO4	4	6
PLO5	5	10

Ten combinations means a PLO5 hand connects with almost every board in some way.

Stronger winning hands

We simulated all-in showdowns where every player sees all five board cards:

Game	Winning hand is a straight or better (6 players)	Winning hand is a full house or better (6 players)
Hold’em	~39%	~12%
PLO4	~78%	~31%
PLO5	~89%	~40%

Real pots don’t all go to showdown six-way, but the direction is clear: hands that are strong in Hold’em — one pair, two pair, even sets — are often not good enough in PLO5.

Closer equities

The best PLO5 hands have smaller edges than in PLO4. From our Omaha evaluator:

• A♠A♥K♠K♥ + 7♣ is about 64% against a random PLO5 hand (compared with about 71% for A♠A♥K♠K♥ in PLO4).
• A strong rundown like J♦T♦9♣8♣7♥ is about 55% against weak aces (A♠A♥7♣4♦2♥) — rundowns gain relative to unsupported aces.

Aces come more often

You’ll hold at least two aces in about 4.2% of PLO5 hands — roughly one in 24, compared with one in 40 in PLO4.

Common mistakes when switching from PLO4

1. Overvaluing two pair and sets. They win far less often at showdown.
2. Playing non-nut draws. Someone often holds the higher flush or straight.
3. Using three hole cards when reading straights — the rule is still exactly two.
4. Bluffing too much, especially multiway. With ten combinations each, opponents connect more often.

Quick check

Why does two pair lose value in PLO5 compared with Hold'em?

Two pair doesn't count in OmahaWith ten two-card combinations each, opponents make straights, flushes and full houses much more oftenThe pot limit stops you betting two pairTwo pair only wins in tournaments

Check answer

Showdown hands are much stronger in PLO5, so two pair is often a bluff-catcher at best.
