Omaha hold’em, often called simply Omaha, is an exciting poker game that is strikingly similar to Texas hold’em, although it does have a number of differences to set it apart.
Unlike Texas hold’em, a game in which the preferred betting structure is no-limit, the most popular betting structure of Omaha games is pot-limit. Games of this type are referred to as pot-limit Omaha, abbreviated as PLO poker.
The first major difference you’ll instantly be aware of when playing PLO poker instead of hold’em is that each player is dealt exactly four hole cards instead of two.
