Poker glossary
Omaha
A poker game where each player gets four (or five) hole cards and must use exactly two of them with exactly three board cards.
Also: PLO, Pot-Limit Omaha, PLO4
Omaha is usually played pot-limit (PLO). Because every player holds several two-card combinations, hands run much closer together than in Hold’em and the nuts matters more. Start with the PLO4 course.
