Omaha Hold ’em Poker
Omaha Hold ’em, or simply Omaha, is similar to Texas Hold ’em in that it makes use of community cards, which are shared cards placed face-up on the table that any player can choose to include in their final hand.
In Texas Hold ’em, a player can choose to use any combination of three hole cards (face-down cards that the player keeps hidden) that are dealt and five community cards.
In Omaha Hold ’em, however, each player must use exactly two hole cards out of four that are dealt and any three of the five community cards to make a hand. See Omaha Hold ’em rules for a detailed description of how the game is played.
Because players in Omaha Hold ’em have one hole card more than players in Texas Hold ’em, there are far more possible card combinations right from the starting hand. Straights and flushes are common, and it’s often said that Omaha is a "nuts game" – meaning a game in which it often takes the best possible hand (the "nuts") to win in a showdown.
To make matters more challenging, Omaha Hold ’em is most often played as a high-low split game, in which the pot is shared between the player who comes out with the highest-ranking hand and the player with the lowest-ranking hand. This means having to evaluate your starting cards in two completely different ways at the same time. It also means that even a royal flush will often win you only half the pot.
