Omaha Poker is a community card poker game similar to Texas Holdem, where each player is dealt four cards and must make his or her best 5 card hand using exactly two of the hole cards and three of the five community cards.
To begin the game, players post a small blind and a big blind before any cards are dealt. There are no antes as the forced small and big blind bets take the place of antes. The blinds and dealer button rotate around the table, so that players take turns being the small blind, big blind, and dealer. After the blinds are placed, each player is dealt 4 cards face-down, instead of 2 as in Texas Holdem. Then there’s a round of pre-flop betting, followed by a three card flop being dealt, which are community cards shared by all players. After the flop is dealt, another round of betting ensues. When this is completed, a fourth community card is dealt, which is called the “turn” card. Another round of betting occurs after the turn card is dealt. A fifth and final community card (“the river”) is then dealt. Players’ complete one last round of betting after the river is dealt, with all players remaining in the hand going to showdown. At showdown all remaining players after the last round of betting then turn over their hands, with the best five card hand winning.
Look for loose games. What you want is tables where the average number of players seeing the flop is at least five.
Pot odds are crucial in Omaha. If you're able to do these calculations correctly you will improve your chances of winning.
If the flop doesn't go your way - fold. You generally need a good chance of winning both hands to stay in the game.
If you do hit the flop you should play your hand(s) aggressively. This is an effective way to increase your profit.
Take advantage of your position at the table. For example you should play more starting hands when you're in late position.
Omaha is a hand-driven game. This means that you should seldom try to bluff your opponents.
