Pot Limit Omaha (PLO) — Complete Strategy Guide

The rule that defines the whole game

In Pot Limit Omaha you are dealt four hole cards instead of two, and at showdown you must use exactly two of them together with exactly three community cards. Not one, not three — exactly two. This single rule is the source of nearly every beginner mistake in PLO. It means four hearts in your hand is not a flush draw at all: you can only ever play two of them, so two of your hearts are dead cards. It means holding A-A-A-x gives you far less than it looks, because two of your aces can never be used together with the third. Betting is pot limit: the largest legal raise is the current pot size after your call, so pots grow geometrically rather than instantly.

Six combinations, not one hand

Four hole cards produce C(4,2) = 6 different two-card combinations. Every one of them is a separate Hold'em hand playing the same board. That is why PLO equities run so much closer together than Hold'em equities: six chances to connect beats two chances almost every time. The practical consequence: made hands lose value and draws gain value. Top pair, which wins plenty of pots in Hold'em, is close to worthless in a multiway PLO pot. Conversely a hand with a flush draw plus a straight draw plus a pair can hold more equity than a made set.

What makes a good starting hand

A strong PLO hand is one where all four cards work together. Judge every hand on four criteria at once, not on the best two cards in it. Connectivity — cards close in rank produce more straight combinations. J-T-9-8 makes far more straights than A-K-7-2. Suitedness — double-suited hands (two cards of one suit and two of another) give two flush possibilities instead of one. Single-suited is fine; rainbow hands are a real downgrade. High-card strength — nut potential matters more than raw connection. No danglers — a fourth card unrelated to the other three effectively reduces you to a three-card hand. The consensus strongest starting hand is A-A-K-K double-suited: two nut flush possibilities, the best pair, and strong straight coverage.

• A♠A♥K♠K♥ — the premium: nut pair, two nut-flush suits, broadway straight coverage
• J♠T♠9♥8♥ — no pair, but enormous straight coverage plus two flush draws
• A♠A♦7♣2♥ — misleading: a big pair with two danglers and no suit support
• A♠K♠Q♠J♠ — the classic trap: four cards of one suit means two of them are dead

Nut potential and why second-best is expensive

In Hold'em you often win with a non-nut hand. In PLO, if a hand is possible, someone in a multiway pot usually has it. This turns "the nuts or a draw to the nuts" into a genuine planning rule rather than a slogan. A king-high flush is a big hand in Hold'em and a liability in PLO — the nut flush is out there and it will be the hand raising you on the river. The low end of a straight is the same trap: with J-T-9-8 on a Q-K-x board you may hold a straight while an opponent holds the higher one. This is why an ace with a matching suit is so valuable in PLO. It is not the ace itself; it is that the nut flush draw is a hand you can build a pot with safely.

Blockers and redraws — the two PLO-specific edges

A blocker is a card in your hand that removes combinations from your opponent's range. Holding the ace of spades means no opponent can have the nut spade flush, which lets you apply pressure on a spade-heavy runout that would otherwise be dangerous. A redraw is equity you still hold after you make a hand. Suppose you flop the nut straight with J-T-9-8 double-suited on a Q-K-x board. You have the nuts now, and if the board pairs or a third suit card arrives you may still improve or still hold the best hand. A player who flops the same straight with J-T-4-3 rainbow has the identical hand right now and no protection at all. The difference between those two hands is invisible in Hold'em terms and decisive in PLO. When you choose which hands to play a big pot with, redraws matter as much as current strength.

Why equities are compressed

Because every player is effectively holding six two-card hands, preflop matchups converge. Aces against a random hand remain a favourite in PLO, but nothing like the 85% that A-A enjoys against a small pair in Hold'em — a strong double-suited rundown can take a meaningful share of the pot against aces. Two strategic consequences follow. First, getting all-in preflop with aces is far less of a jackpot than Hold'em players expect, which is one reason PLO is played as pot limit rather than no limit. Second, postflop equity swings are enormous: a hand that is 40% on the flop and 0% on the turn is completely routine, so betting for protection and denying free cards has more value than in Hold'em.

Pot limit betting: how the sizing actually works

The maximum bet is the size of the pot. The maximum raise is the pot after you call — count your call first, then the pot. Worked example at 1/2 blinds. The pot is 3. A player raises to 7. To compute your maximum re-raise: call the 7 (pot becomes 3 + 7 + 7 = 17), then raise by that amount, for a total of 24. The important structural consequence is that stacks go in over multiple streets rather than in one shove. That gives you more chances to fold a hand that turned into second-best, and it makes stack-to-pot ratio a live consideration on every flop. A pot-sized bet on the flop and another on the turn is usually all the money — plan the hand backwards from that.

The mistakes that cost new PLO players the most

Nearly all of them are Hold'em instincts applied to a game with four cards.

• Playing four cards of one suit and calling it a flush draw — only two of them can ever play
• Over-valuing A-A-x-x with two unconnected, unsuited side cards
• Stacking off with top pair or an overpair on a coordinated board
• Building a big pot with the low end of a straight
• Chasing a non-nut flush in a multiway pot
• Ignoring redraws when deciding which made hand to commit with
• Playing too many hands because "any four cards can flop something" — they can, and usually something second-best
• Forgetting pot-limit geometry, so a flop call leaves an awkward turn stack

Two worked hands

Hand 1 — you hold A♠K♠Q♥J♥, the flop is T♦9♠2♠. You have the nut straight (using Q-J with T-9), the nut flush draw (A-K of spades), and additional straight redraws. This is the archetypal PLO hand to build a pot with: you hold the nuts now and you keep improving on most bad runouts. Hand 2 — you hold A♦A♣8♠3♥ and the flop is J♠T♠7♦. You have an overpair and nothing else: no flush possibility, no straight coverage, and a board that hits every rundown hand your opponents play. Against a raise this is a fold, and the fact that it is aces has no bearing on that. Recognising that difference is most of early PLO improvement.
