Omaha is a game played with four hole cards, although versions with five and six cards have also caught on.

​

Pot-Limit Omaha, or PLO for short, is the second most common form of poker behind No-Limit Hold’em (NLHE). The term “Pot-Limit” restricts betting to the size of the pot, so you can’t overbet the pot, or move ‘All-In’ as you can in No-Limit games.
