In the pot limit Omaha poker game, the button (a small disc) indicates which player is the dealer for the current hand. Before a hand starts, two players must post the blinds (two obligatory bets to start the action). The player to the left of the button posts the Small Blind (SB) and the player two to the left of the button posts the big-blind. The blind denominations are typically half a small bet, and a small bet (e.g. , theBB is $1 in a $.5/$1 Omaha game, while the SB is $0.50). The player immediately clockwise the small blind posts the “big blind”. Each player then receives their 4 hole cards. Betting action proceeds around the table, starting with the player immediately clockwise the big blind (first to act – this position is known as “under the gun”).
Now, three community cards (the “flop”) are dealt face-up on the board. These three cards can be used by players still in the hand to form their poker hand (5 cards, using two of their hole-cards). Play begins with the first active player immediately to the left of the button. All bets and raises occur in small bets (increments of $2 in a $2/$4 game).
Once betting action is completed for the first street (the flop round), the fourth community card (the “turn”) is dealt face-up on the board. The betting round once again begins with the active player immediately clockwise the button. In this round of Omaha, betting doubles from the small bet to the big bet. In a $5/$10 game, betting on the turn is done in $10 increments.
When betting action is completed for the turn round, the final community card in the Omaha hand (the “river” card) is dealt face-up on the board. Once again, betting begins with the active player immediately clockwise the button.
If a player raises on the river and everyone folds, the raiser wins the Omaha hand. If there is more than one player remaining after the final round of betting, the last bettor or raiser shows his or her cards. If there was no bet on the final round, the remaining player immediately clockwise from the button shows their cards. The player with the best five-card hand (comprised of two of their four hole-cards, combined with three from the board) wins the pot. In the quite unlikely event of remaining players having identical poker- hands, the pot will be equally divided between the players with the best hands (this is called a “chop”).
Once the pot has been awarded to the winner in the hand, a new Omaha poker hand is ready to be played, and the dealer button is moved clockwise to the next Omaha player.
