Poker Rules – Omaha

In Omaha each player is dealt four personal cards face down (known as ‘hole cards’) and five shared community cards are dealt face-up, to form the ‘board’.
All players in the game use 3 of these shared community cards and 2 of their own hole cards to make their best possible five-card poker hand – no other combination is allowed.
There are four types of Omaha, with different betting structures:

Limit Omaha

The bet or raise value is a fixed amount on all streets, equal to the Big Blind pre-flop and on the flop and DOUBLE the Big Blind (equal to a Big Bet) on the turn and river.
A maximum of 3 raises are allowed during each betting round (raise, re-raise and cap), putting a betting ceiling of 4 x Big Blind pre-flop and on the flop and 8 x Big Blind (or 4 x Big Bet) on the turn and river.

No Limit Omaha

The minimum bet is the size of the Big Blind on all streets.
A raise must be AT LEAST equal to the previous bet or raise in the same round.
The maximum raise is the size of your stack (chips or money at the table).
There is no ‘cap’ on the number of raises allowed.

Pot Limit

The minimum bet is the size of the Big Blind on all streets.
A raise must be AT LEAST equal to the previous bet or raise in the same round.
The maximum raise is the size of the pot, equal to:
The active pot + All bets on the table + The amount the active player must first call before raising.
There is no ‘cap’ on the number of raises allowed.

Mixed Omaha

The game switches between rounds of Limit Omaha and Pot Limit Omaha.
The blinds are increased when the game switches from Pot Limit to Limit, to ensure some consistency in the average pot size in each game. The betting rules on each round follow the rules for that game, as described above.

Buy-in

In Pot Limit and No Limit, the games are referred to by the size of their blinds (for example, a 1/2 NL or PL Omaha game has a small blind of $1 and a big blind of $2).
There is normally a maximum buy-in of 100 x the big blind and the example above could also be referred to as a NL200 or PL200 game with a maximum buy-in of $200.
In Limit, the games are referred to by the size of their bet values (for example, a 3/6 Limit Omaha game has a $3 bet size pre-flop and on the flop and a $6 bet size on the turn and river).
There is no maximum buy-in for Limit Omaha games.

Setup

There are two types of initial forced bets:
1. Small Blind
2. Big Blind

The Big Blind is normally twice the Small Blind, but the ratio can vary in Limit games if the Big Blind value is not an even number.
The player sitting to the left of the dealer button posts the small blind and the player to his left posts the big blind.

The Deal

All players are dealt four cards face down (hole cards).

Pre-flop (Betting Round 1)

The action proceeds clockwise around the table, starting with the player to the left of the big blind (in the ‘under the gun’ position).
The player may match the big blind bet, make a raise or fold.
The betting moves around the table until every player has had a chance to act and has either folded out of the hand or bet the same amount as everyone else still in the hand.
Note – A player must match the previous bet, raise or fold, he cannot pass by checking in the first round of betting.

The Flop (Betting Round 2)

If at least 2 players remain three community cards are dealt face-up (The Flop) and are available to all players still in the hand.
The action proceeds clockwise around the table, starting with the first player still in the hand to the left of the button.

The player may either check or bet.

The betting moves around the table until every player has had a chance to act and has either folded out of the hand or bet the same amount as everyone else still in the hand.
Note – A player must match the previous bet, make a raise or fold. If no player has bet, he may check or bet. If nobody bets during the round a turn card is dealt for free.

The Turn (Betting Round 3)

If at least 2 players remain the fourth community card is dealt face-up (The Turn or Fourth Street) and is available to all players still in the hand.
The betting process for the Flop is repeated on the Turn.

The River (Betting Round 4)

If at least 2 players remain the fifth community card is dealt face-up (The River or Fifth Street) and is available to all players still in the hand.
The betting process for the Turn is repeated on the River.

The Showdown

If two or more players remain in the hand after all betting is complete, all players display their best 5 card hand (2 hole cards and 3 community cards) in a showdown to determine the winner.
The player with the highest five-card poker hand wins the pot.
If two or more winning hands have the same value, the pot is split equally between them (all suits are equal for the purposes of awarding the pot).
