variant of poker are unknown, although it first appeared in a casino setting at the Las Vegas Golden Nugget Casino. The full name of the variant was originally “Omaha Hold'em” as outlined in Doyle Brunson's super system. Omaha Hold'em is synonymous with a variant of Hold'em poker known as “Tight Hold'em” where players must use both of their holecards to construct a 5 card hand. (In the modern version of Hold'em players can use both, one, or none of their hole-cards to create a 5card hand).
The “Omaha” part of the name “Omaha Hold'em” reflects this rule of using exactly 2 hole-cards. “Hold'em”, refers to the fact that players share a pool of community cards which they can use to make their 5-card hand. This is different from draw games where players have purely face-down hole-cards, and stud games where players have a mixture of face-up and face-down hole-cards but no community cards.
The action and betting rounds are identical to no-limit-hold'em but there are some important differences that must be kept in mind.
a) Players are dealt 4 hole-cards instead of the 2 in Texas Hold'em.

Similar to all other variants of poker each player starts with a number of “chips”. These are small circular bits of plastic which are used for betting and keeping score. Generally these chips can be traded in for their monetary value after the game is over. The objective of the game – to win your opponents chips. In a poker tournament, you win by accumulating all of the chips on the table.
Omaha is more frequently played with a pot-limit betting structure meaning it is not possible to go “all-in” unless the pot size is sufficiently large.
Blinds/Position
As with Texas Hold'em, a hand of Omaha can consist of anywhere between 2 and 10 players, with one player being the dealer. The rules on blinds and position are again exactly the same as Texas Hold'em.
Again like Texas Hold'em, Position is very important in Omaha because it determines the order of betting. The best position at the table is generally considered to be the BTN, while the worst is considered to be either the SB or UTG.
Playing a Hand of Omaha
Again the same as Texas Hold'em - The gameflow is broken down into rounds known as “streets”. Each hand of Omaha is broken down into 4 streets referred to as “preflop”, “flop”, “turn” and “river”.
On each street a round of betting takes place. If more than one player is left in the hand by the river we reach what is referred to as “showdown”. All remaining players show their hands and the best hand takes the chips or “pot” that is in the middle.
Betting
Betting rounds and actions are exactly the same as Texas Hold'em. Pre-flop, Flop, Turn and River mark the rounds of play in Omaha.
Players may either check, bet, call or raise during each round.

Betting Structure
The most popular
version of Omaha is the pot-limit version. There is a cap on the amount we can raise in any given situation (more on calculating a pot-sized bet shortly). However it's also possible to find Limit-Omaha games, (raising in small fixed increments) and No-Limit Omaha games.
In Pot-Limit-Omaha (PLO) we can raise only to the pot-size at any given time. The only way the betting action can continue after this is if our opponent chooses to re-raise us. He will then also be again limited to a pot-sized re-raise. Calculating a pot-size raise sounds simple but causes much confusion in the poker world. The majority of poker players possibly do not even know how to calculate a pot-sized raise because-
a) it's automated in an online environment
b) it's possible to ask the dealer what a pot-sized raise is in a live setting
However, it can be useful to know for ourselves how to calculate it. We can use the following formula
3 * size of opponents bet(or)raise + size of the initial pot
So imagine there is $10 in the pot and our opponent bets $5, what would be a pot-sized raise here?
Probably our instinct might tell us that we raise an extra $15 for a total raise size of $20. But this is where we'd be wrong.
Let's apply the formula
(3*$5) + $10 = $25
We can raise to $25 here. If formulas are not your strong point – we are effectively imagining that we call first to see what the total pot is. In other words the total pot would be $20 if we just called. So we raise that extra $20 on top of our opponents $5 to give us our total raise size of $25. And remember, if you are not sure, ask the dealer – they are paid for stuff like this.
Why Play Omaha
So what is it that makes Omaha so exciting? And why do many players make this their game of choice as opposed to No-Limit-Hold'em?
Omaha has sometimes been described as “Hold'em on steroids.” The fact that we are now dealt 4 hole cards instead of 2 means that big hands are a lot more common. The fact is that most of the time in No-Limit Hold'em we are simply going to miss the flop. We'll still miss the flop a fair amount in Omaha, but a lot less often. More big hands can result in more action.
The game is tougher to pick up than No-Limit-Hold'em. For some this is a bad thing, while others enjoy the increased complexity of the game. Even reading our own hand takes a lot more work since we have twice as many hole-cards to think about. Establishing exactly how strong our holdings are when we have a made hand and several draws is a skill in itself. We may even need to question how strong our holdings are when we hold the stone cold nuts. We can't automatically get all of the money in even in these circumstances. Our opponent could also hold the nuts along with a strong redraw which makes putting our stack in unprofitable.

Similar to No-Limit Hold'em, Omaha is also a game of skill that can be beaten in the long term with enough work. The good news is that the average competition at Omaha games is a lot weaker than in Hold'em games. So even though it takes a little longer to figure out the basic rules, it can potentially be more lucrative than playing No-Limit Hold'em.
Omaha Tips for Beginners
- We need to use exactly two of our hole-cards and three cards from the board to make a 5-card hand. Can't stress this enough. This is easily the most common mistake players transitioning from NLHE make.
- Play 4 cards which work well together. The best starting hands in Omaha are comprised of hole-cards that work well together as a 4 such as AA10J. Non co-ordinated cards are sometimes referred to as “danglers”. It should be easy to see why the 3 in the hand AA103 is not really that useful. We would also rather have AA10J than AA10J. Since we can only use two of our hole-cards, having the J means we block some of our spade-flush outs. The worst hand in Omaha is considered to be 2222. It will hardly ever improve since the cards it needs are no longer in the deck.
- Stronger hands. If we come from a Hold'em background, we will need to up our standards for what constitues a strong hand. Bottom set in NLHE is considered a relative monster. Bottom set in Omaha will get us into a ton of trouble. If our opponent wants to stack off he will have a higher set the vast majority of the time. As such our stacking off range in any spot should be the nuts or at least very close to it. Even 2nd nut flushes are huge problem hands for beginners since they will nearly always be up against the nut-flush when there is a lot of action.
- Nuts is not always nuts. Even with the stone cold nuts there may be situations where folding is correct. If we have the nuts and no redraw it will be a losing play to stack off vs our opponent who also has the nuts but with a strong redraw.
- Wraps. Wraps are very strong hands in Omaha and are straight-draws with additional fire power. They will have significantly more outs than a straight-draw in NLHE. For example we hold T-9-6-5 on a board of 8-7-2. We have 20 possible outs to make a straight!
Even with the stone cold nuts there may be situations where folding is correct.
