In short
Omaha is a poker variant where each player receives four hole cards and must use exactly two of them, plus exactly three community cards. The extra cards produce much stronger hands and far bigger swings than Hold'em.
Omaha is Hold’em’s wilder relative. The structure is nearly identical, blinds, flop, turn, river, but each player gets four hole cards instead of two.
The rule everyone gets wrong
You must use exactly two hole cards and exactly three community cards. Not one, not three, not four.
If the board shows four hearts and you hold the ace of hearts, you do not have a flush unless you hold a second heart. This catches Hold’em players constantly, and it catches them expensively.
Why hands are so much stronger
Four hole cards produce six possible two-card combinations per player, against one in Hold’em. Everyone has far more ways to connect with the board.
The practical effect is that hand values inflate dramatically:
- Top pair is usually worthless
- Two pair is rarely good enough
- A straight is often beaten
- The nut flush is frequently the minimum for a big pot
- Full houses appear constantly
A hand that would win comfortably in Hold’em is routinely third-best in Omaha.
Pot limit
Omaha is almost always played pot limit rather than no limit, meaning the maximum bet is the size of the pot. No-limit Omaha exists and is considered close to unplayable, because equities run so close together that stacking off pre-flop becomes near-random.
Pot limit still allows rapid escalation, since pot-sized bets compound quickly.
Variance
Omaha has far higher variance than Hold’em. Because hand equities are closer together, a big favourite pre-flop in Omaha might be 60/40 rather than 80/20. Results take much longer to reflect skill.
Bad beats are routine rather than notable. A bankroll appropriate for Hold’em is generally considered inadequate for Omaha at the same stakes.
Hi-Lo
Omaha Hi-Lo (Omaha 8 or Better) splits the pot between the best high hand and the best qualifying low hand. Five unpaired cards of 8 or lower. You may use different pairs of hole cards for each half, which makes hands that scoop both halves extremely valuable and the game considerably more technical.
Common questions
Why must I use exactly two cards in Omaha?
It is the defining rule of the game. Four hearts on the board and one in your hand is not a flush unless you hold a second heart. This catches Hold'em players constantly and expensively.
Why is Omaha higher variance than Hold'em?
Because four hole cards give six two-card combinations per player, so everyone connects with the board far more often. Equities run much closer together, meaning a big pre-flop favourite might be 60/40 rather than 80/20.
