Omaha poker is similar to Texas hold ’em poker, but players have more hole cards in Omaha, which gives them a better chance of making a high-ranking hand. The betting rounds and poker hand rankings are the same in both games.
Omaha poker is a community card poker game where players use two of their four poker cards and three of five community poker cards to make a five-card poker hand. The player with the best hand wins the pot. Here are some rules for playing Omaha.

CARDS:
Each player is dealt four cards face down from a standard 52-card deck.

BETTING:
Players take turns betting after each round of cards are dealt.

COMMUNITY CARDS:
Three cards are dealt simultaneously to the table for all players to use, called the flop. Another card, called the turn, is then dealt, followed by the river, which is the final community card.

HAND:
Players must use exactly two of their four poker cards and exactly three of the five community poker cards to make their best hand. For example, an ace of hearts and a king of diamonds is an ace high hand.

SHOWDOWN:
After all bets have concluded, the players reveal their hands and the player with the highest ranking hand wins the pot.

In Texas Hold’em poker, you may use any combination of your two hole cards, or leave one of them out altogether. You can use four cards from the community cards and one from your hand, or two from your hand combined with three from the community board.

Omaha poker is a bit trickier. You must use 2 of your hole cards when forming your best possible poker hand. If all hearts are showing on the board, and you are holding an ace of hearts and a king of diamonds, you would have a flush in Texas Hold’em. When playing Omaha, you would simply be holding an ace high hand, since both cards must be used.

BETTING STRUCTURES:

POT LIMIT – In this popular variation, the maximum amount that can be bet is the total sum of the chips in the pot. This makes it inexpensive to begin the hand, but can become quite risky and costly by the end.

FIXED LIMIT – In this version, a pot can only be raised a maximum of four times and the bet or raise must be equal to the size of the blinds. Not a lot of folding takes place in this version, as it is relatively inexpensive to stay in the game.

NO LIMIT – In this aggressive version , players can bet or raise as much as they desire and at any point during the betting.

VARIATIONS OF THE GAME:
Omaha Hi – Just as it sounds, in this version, the highest five card hand takes the pot Fixed Limit – In this version, a pot can only be raised a maximum of four times and the bet or raise must be equal to the size of the blinds. Not a lot of folding takes place in this version, as it is relatively inexpensive to stay in the game.

Omaha Hi/Low – A common variation, the pot is split between the highest and lowest hands. An example of a low hand is one that would be a loser in any other game. For example, if you are holding a 7 of hearts and a 6 of diamonds and combine those with a 4, 3, and 2 of any suit on the board, you’d have a very strong “low hand”. In Omaha Hi/Low, the best possible hand is one in which the same player holds both the highest and lowest hands simultaneously, thus winning the entire pot.
