Pot-Limit Omaha is a popular variant of poker where players are dealt four hole cards instead of two, as in Texas Hold'em. Each player must use exactly two of their hole cards and three of the five community cards to make the best possible five-card hand. In Pot-Limit Omaha, the betting structure allows players to bet any amount up to the total in the pot at the time of their turn. This creates larger pots and more strategic play, as players must consider both their hand strength and the potential for their opponents' hands.
