Omaha Poker, a popular variant of Texas Hold'em, features unique winning hands due to its four hole cards. The best hand is still a royal flush, followed by straight flushes and four of a kind. However, players must use exactly two of their hole cards and three from the community cards to form their hands, making strategic hand selection crucial. Strong hands like full houses and flushes can emerge frequently, leading to exciting gameplay and significant pots. Understanding hand rankings and the dynamics of Omaha is essential for success in this thrilling poker variant.
