Omaha poker, and the rule everyone gets wrong first

How a hand of Omaha plays out

If you know Hold'em, you already know the shape of an Omaha hand. A button marks the nominal dealer and moves one seat clockwise every hand. The two players to its left post the small and big blinds. Cards are dealt, and the hand runs through four betting rounds: preflop, then the flop of three shared cards, the turn, and the river. Action after the flop starts with the first live player left of the button, and the button acts last.

The Hold'em page walks through that sequence in detail if any of it is unfamiliar.

The differences are two, and both arrive at the deal. Every player receives four cards face down rather than two. And the game is almost always played pot-limit rather than no-limit, which is why the game is usually written PLO, pot-limit Omaha.

At showdown you build the best five-card hand you can under the two-and-three rule, and the standard poker rankings apply without modification. A royal flush is still the top hand, a full house still beats a flush, and suits still do not break ties.

The two-and-three rule, with the examples that catch people

This is the whole game, so it is worth being slow about. You hold four cards. Your final hand is exactly two of them plus exactly three of the five board cards. You have no choice about the quantities, only about which cards.

The first row is the mistake that costs the most money in low-stakes Omaha. Four hearts in your hand is not a flush draw; it is a hand with two of its cards wasted, because only two of them can ever play. The same is true of four to a straight and of trips in your hand. Holding three kings means only two of them count, and the third is a card that can no longer come to help you.

Turned around, the rule is also why boards get dangerous fast. Everyone at the table is choosing from six two-card combinations out of their four cards, so somebody usually has the straight, the flush or the full house that the board is offering. In Hold'em the top pair is often good. In Omaha it is a hand you are looking to fold.

How pot-limit betting is calculated

Pot-limit is the only part of Omaha that involves arithmetic at the table, and dealers will work it out for you if you ask for "pot". Doing it yourself takes one step: your maximum raise is the current pot, plus all bets on the table, plus your own call.

Worked through with real numbers. The pot holds RM100. An opponent bets RM100, so there is now RM200 on the table. You may call the RM100, which would make the pot RM300, and then raise by up to that RM300, so your maximum is RM400 in total. That is what "pot" means when someone announces it.

The practical effect is that Omaha pots grow geometrically rather than in one jump. Nobody moves all in preflop for a hundred big blinds, but three raises later the money is in anyway. It also means stack sizes matter enormously: a short stack in PLO can be committed by the second raise, whereas a deep stack still has room to play the turn and river.

No-limit Omaha does exist and some rooms spread it, but it is a much wilder game for exactly the reason pot-limit was chosen in the first place: with hands running so close together, unlimited betting turns most pots into a coin flip for everything.

What a good Omaha starting hand looks like

Four cards give you six two-card combinations, and a good Omaha hand is one where most of those six do something useful together. That single idea replaces the whole starting-hand chart people arrive looking for.

• All four cards should work. A hand like K-Q-J-10 double-suited is strong because every pair of cards connects and both suits can make the flush. A hand like A-A-8-3 rainbow is really a two-card hand with two spectators.
• Double-suited beats single-suited. Two suits in your hand means two flush possibilities, and each one only needs three of that suit on the board.
• Aim at the nuts. Omaha punishes second-best hands harder than any other variant, because so many players reach showdown with something. A king-high flush draw is a way to lose a big pot; the ace-high flush draw is a way to win one.
• Watch for danglers. A hand such as A-A-K-2 with the deuce unconnected and unsuited is effectively three cards. It is playable, but not as strong as it looks on first glance.

Aces are still the best pair to hold, but they are nowhere near the favourite they are in Hold'em. Pocket aces in Hold'em beat a single random hand roughly 85% of the time; in Omaha, a strong four-card hand against another decent four-card hand is often close to a coin flip, because both players can improve in so many directions. That compression is the real character of the game: fewer certainties, bigger pots, and much more variance for the same amount of skill.

Omaha Hi-Lo, also sold as Omaha 8 or Better

Hi-Lo splits the pot between the best high hand and the best qualifying low hand. The deal, the betting and the two-and-three rule are identical. Only the showdown changes.

A low hand qualifies only if it uses five cards ranked eight or lower with no pairs. That is what the "8 or better" in the name means. Aces count as low. Straights and flushes do not disqualify a low, so the best possible low is A-2-3-4-5, which is also a five-high straight for the high half. If nobody makes a qualifying low, the high hand takes the whole pot.

The detail that makes the game interesting is that you may use a different pair of your cards for each half. Holding A-2-K-Q on a board of 3-4-9-K-Q, you can play A-2 with 3-4-9 for the nut low and K-Q with K-Q-9 for two pair on the high side, from the same four cards. Winning both halves is called scooping, and it is where nearly all the profit in the game lives.

Because of that, hands containing an ace and a deuce are worth far more here than their high-only value suggests, and hands with four high cards and no low potential are worth playing only when they can win the whole pot outright.

The mistakes that cost the most in Omaha

• Reading your hand as a Hold'em hand. Top pair with a good kicker is close to worthless. If a board can make a straight or a flush, assume somebody has it, because usually somebody does.
• Drawing to the second-best version of a hand. Chasing a queen-high flush in a big pot is the classic way to lose a stack. The nut draw and the second-nut draw are not similar hands.
• Playing any four cards. Every hand looks playable in Omaha, which is precisely the trap. If two of your four cards are doing nothing, you are entering the pot with a handicap that never goes away.
• Overvaluing a set on a coordinated board. Sets are much less valuable than in Hold'em, because full houses are common and because a flopped set is often already behind a made straight.
• Forgetting the pot-limit ladder. Calling a pot-sized bet on the flop commits far more of your stack than the same call in a no-limit game, because the next bet is bigger again.

None of these are subtle plays. They are all the same error in different clothing: treating four cards as two cards with spares, instead of as a hand where the relationships between the cards are the hand.

Before you play Omaha for money

Omaha's variance is higher than Hold'em's at the same stakes, and that is a mathematical property of the game rather than a run of bad luck. Hands run close, so the better player's edge shows up over a much longer sample, and losing stretches are longer and deeper. Anyone who tells you a strategy makes the game reliable is selling something; no betting pattern removes variance, and no system guarantees a winning session.

That makes Omaha a bankroll question before it is a strategy question, and online a bankroll sits inside somebody else's system rather than in your pocket. How a real money poker balance actually behaves is worth reading before you move up a level.
