Omaha
奥马哈
Context: Poker term: Omaha Omaha is a variant of Texas Hold'em in which each player is dealt four hole cards and must use exactly two of them together with three community cards to form the best five-card hand. In practice, because Omaha involves more hole card combinations, hand strength relies more on made hands than on bluffs. Players need to carefully evaluate the nuts (the best possible hand) to avoid being outdrawn. For example, when a flush draw appears on the flop, if you hold two suited hole cards but an opponent may have a higher flush or straight draw, you must weigh the implied odds and avoid over-committing.

Basic Rules
Omaha is one of the most popular poker variants after Texas Hold'em. Unlike Texas Hold'em, each player receives four hole cards instead of two. After each betting round, five community cards are dealt in sequence (three flop cards, one turn card, one river card). Players must use exactly two hole cards and three community cards to form the best five-card hand.
Hand Rankings and Comparison
The hand ranking order in Omaha is identical to Texas Hold'em: Royal Flush > Straight Flush > Four of a Kind > Full House > Flush > Straight > Three of a Kind > Two Pair > One Pair > High Card. However, since two hole cards must be used, hand combinations are more complex, and players need to carefully evaluate the coordination between hole cards and community cards.
Common Variants
- Pot-Limit Omaha (PLO): The most popular form of Omaha, where the maximum bet is the current pot size.
- Limit Omaha: Each betting round has fixed limits.
- No-Limit Omaha: Players can go all-in at any time, but this is less common.
Strategy Points
- Hand Selection: In PLO, strong starting hands are usually coordinated, suited, and contain high cards (e.g., A-K-Q-J double-suited). Single strong hands (e.g., A-A-7-2) have lower value.
- Nut-Oriented: Since each player has four hole cards, the probability of making strong hands is higher, so you typically need the nuts (the current best hand) to win a large pot.
- Drawing Hand Value: Drawing hands (e.g., straight draws, flush draws) are very common in Omaha and often have multiple outs, making semi-bluffing and pot control more important.
Differences from Texas Hold'em
- Number of hole cards: 4 vs 2.
- Usage rule: Must use exactly 2 hole cards vs can use 0-2.
- Hand strength distribution: Players in Omaha are more likely to make strong hands, leading to more aggressive action and higher variance.
Typical Example
Suppose your hole cards are A♥K♥Q♠J♠, and the community cards are 10♥9♥8♣3♦2♠. You can use A♥K♥ with the community cards to make A♥K♥10♥9♥8♥ (a flush), or use Q♠J♠ with the community cards to make Q♠J♠10♥9♥8♣ (a straight). Note that you cannot use three hole cards.
