Omaha is very similar to Texas Hold’em with one game changing factor. Instead of two hole cards, each player is dealt four hole cards. In Omaha, players must make the best possible hand with a combination of two from their hole cards and three from the community cards.
In Pot Limit Omaha (most popular form of Omaha Poker), the maximum a player can bet is the amount that is in the pot. For example, a $100 bet into a $100 pot.
The showdown begins when there are two or more players who are still in play when action ends on the river. The player with the strongest hand will take the pot. When the showdown ends in a tie, the pot is split evenly among the winning players.
