How to Play Omaha/8 (High-Low)

By Tom "TIME" Leonard

The high-low split pot version of Omaha is a fun and exciting game, which we will refer to as Omaha/8. It is typically played as a fixed-limit game, but the pot-limit variety (known by the abbreviation PLO/8) is also popular, particularly online. The format, betting structure, and requirement to use two cards from your initial four hole cards, in conjunction with three cards from the board, is all the same as Omaha high but coupled with the addition of the best high and best low hands splitting the pot.

In our lesson on how to play Omaha we outlined that one major difference between Omaha and hold’em was the number of potential hands vying for the pot. In Omaha/8 that number remains constant as each hand still has six possibilities but now some of them are vying for the low end and others for the high. What this translates to is an action packed game with numerous bets and raises and large pots.

Omaha/8 Showdown Rules

Omaha/8 is a split pot game, which means that unless someone scoops the pot it will be split. There are two ways to scoop the entire pot. The first is to have both the best high and low hands. The other way is to possess the best high hand when no hand qualifies for the low.

The High Hand

The high hand in Omaha/8 is the identical to a winning hand in Omaha high. If there is no qualified low hand then the best high hand will win the pot.

Qualifying Low Hand

The rules for a qualifying low hand are as follows:

  • Players may use any five cards in their hand for the low
  • A low hand is five unpaired cards, no higher than an eight
  • Aces are low for the low hand (and high for the high hand)
  • Flushes and straights do not negatively impact the low hand

Ranking Low Hands

Low hands in Omaha/8 are ranked ‘top down’, from the highest card in the hand. For example ah2s5d6c7s is lower than as2d5c7h8s. This is an example of a “7 low” versus an “8 low”.

If the highest card is equal in rank then the next highest card is used to determined the lowest hand. This means that ah2s4c5h7s is lower than ah2s5d6c7s because the second highest card among the five is lower. If the second highest card was the same then it would go to the third, fourth, and fifth card respectively. If players share the same low cards then the low half of the pot is split.

The best possible low hand in Omaha/8 is A-2-3-4-5, known as a ‘wheel’. Remember that low hands that are straights and flushes do not disqualify it from being low but, in fact, make it a two way hand and a candidate to scoop. While a Royal flush and a five high straight, called a wheel, would represent the best high and best low hands, the hand you really want at the showdown is a five high straight flush to scoop the pot with the best high and low hands.

Omaha/8 Hand Examples

The basic rules are the same as Omaha high, in that you must use two of your hole cards with three on the board.

Omaha 8 Hand

In the above example a low hand is not possible because the board doesn’t contain three cards that are eight or lower. Only the best high hand will win. The nuts for this board would be someone holding Jack-Queen for the straight. With ahas3s4h (which is an excellent starting hand in Omaha/8) you would use ahas along with the kstc9s on the board to make a high-hand of one pair.

Here is a hand that would qualify for both the high and the low:

Omaha/8 hand, for high and low

In the above example the board contains three card no higher than an eight; the 8d7h3s. The hole cards in this example are very strong. In Omaha/8 you can use any two of your cards for the low and any two for the high-hand. The asjs can be used for the nut high hand (flush) and as2hcan be used for the nut low ( A-2-3-7-8). This is a prime candidate for scooping the pot.

If you’re unsure how to work out low hands, which can be confusing at first, then don’t worry. The key is to count backwards from the highest low card first. As mentioned, the best low hand is A-2-3-4-5 which is a five-low hand, which when counting backwards would obviously be 5-4-3-2-A. The next best low hand would be a six-low of 6-4-3-2-A, followed by 6-5-3-2-A, then 6-5-4-2-A, then 6-5-4-3-A and so on. The highest card is counted first and if there’s a tie the next highest low card is counted.

The split pot rule makes it a very different game to Omaha-high. But it’s important to stress that Omaha/8 is not a game of splits. Whilst the best high hand will win half the pot and the best low hand will win the other half; scooping the entire pot is the true object of this poker game.

This game seems to have polarized poker fans in so far as they either love it or have a disdain for it. I like to call those who love it Omaholics and you should be careful, for if you are just getting started in this addictive form of poker, you may well join their ranks.
