Pot Limit Omaha is similar to Texas Hold'em, except that instead of two cards, players are dealt four. Unlike Texas Hold'em, where you may construct the greatest hand with just one or none at all from your hole cards, Pot Limit Omaha mandates you to play two cards from your stack at showdown. If there are four clubs on the board, for example, possessing the ace of clubs in your hand earns you a flush in Hold'em, irrespective of what your other card is. In Pot Limit Omaha, you ought to have two clubs in your hand to get a flush.
