What is Omaha?

Omaha, most commonly played in its Pot-Limit form and abbreviated PLO, is a community-card poker variant closely related to Texas Hold'em but with a crucial difference: each player is dealt four hole cards instead of two. The defining rule is that a player must use exactly two of their four hole cards combined with exactly three of the five community cards to make their five-card hand — no more and no fewer of each. Worked example: you hold the ace of spades, the king of spades, the seven of hearts and the two of clubs, and the board is queen, jack, ten, all of spades, plus a four. It is tempting to read this as a made flush, but the exactly-two rule means you can only use two of your hole cards. Using the ace and king of spades gives you the broadway straight, ace through ten; you cannot make a flush, because that would require using only one spade from your hand. A newcomer from Hold'em frequently misreads such hands, which is the classic Omaha error. Why it matters: the four-card starting holding produces far stronger average hands and many more big draws and combination draws than Hold'em, which raises both the variance and the strategic complexity. PLO is the second most popular poker variant in the world after Texas Hold'em. The most common and costly mistake is forgetting the two-from-hand requirement and overvaluing apparent flushes or full houses that the rules do not actually permit. Hand-reading discipline is essential. See also Texas Hold'em related Hold'em, board and pot odds.
