Omaha 8 or Better  from PartyPoker.com

Omaha 8 or Better (also known as Omaha Hi/lo) is a popular poker game in the world. Usually there are two types of Omaha 8 or Better games played:

Limit Omaha 8 or Better (there is a specific betting limit applied in each game and on each round of betting) Pot Limit Omaha 8 or Better (A player can bet what is in the pot.)

The Omaha 8 Game:

Omaha 8 or Better Poker uses what is called a dealer-button to indicate the theoretical dealer of each hand. After each hand is completed, as with standard poker rules, the button moves clockwise to the next active player. This player will be considered “the dealer” for that hand. Online poker rooms use what is called the Random Number Generator (RNG) to shuffle a deck of cards for the hand.

How does it work?
The system generates a random set of numbers, which are used to place a card of the deck in a particular position. Once the complete deck is created, the deck is used for that particular hand only. We shuffle the deck of cards every time we start a hand, and the random numbers previously generated are discarded and new ones generated before the shuffle. The RNG code has been successfully audited by BMM, Australia, and its integrity is verified daily. BMM is one of the leading auditors of gaming solutions in the industry.

The First round of Omaha 8:

A fresh table starts of with the first person sitting on the table becoming the dealer and the next player posting the small blind. A new game on an active table starts with the button moving clockwise to the next player. The player next to the button / dealer is required to place the small blind. The small blind is equal to half the lower stake. This is a guideline for determining the blinds and not a strict rule. The small blind is usually rounded down to the nearest dollar. For example – at $5/$10 Omaha 8 or Better per the formula the small blind should be $2.5. Instead, it is rounded of to the lower dollar, so the small blind would post $2. However, as it is just a guideline, the amount of small blind could be set differently at the time of setting up the table.

The player to the left of the small blind is required to post the big blind, equal to the lower stake limit. In a certain scenario it is possible for more than one player to post a big blind in a hand. This is if a new player joins a table at which a game is already going on. The player would get an option of placing a Big Blind at the start of the next hand or wait for his/her turn (as decided by the movement of the button) to place the Big Blind in turn. All the blinds in Omaha 8 or Better poker are considered live bets and the players who posted them will have the option of checking, calling, raising or folding when the betting returns to their position.

After the blinds have been placed, the down cards / hole cards are dealt to each active player. In Omaha 8 or Better, 4 cards are dealt to each of the players, after which the first betting round starts. The player to the left of the player who placed the big blind starts the betting for this round. Each player will now have the option to place his or her bets in the first round, which is set at the lower limit of the stakes structure. For example in a $10/$20 Omaha 8 or Better game, value of each bet is $10 for the first round. When we say the bets are limited to $10, it refers to: a Bet (single bet) of the value of $10, so when a user places “BET” then it is $10, “RAISE” would be $20 – includes one additional bet and a call on the previous bet placed by a player. Bets can be placed by playing any of the following options – Bet, Call and Raise. Each player will also have the option to Fold. These options are available to each player depending on the action taken by the previous player. The first player (left of the Big Blind) to act (in the first round) would get the Bet, Call and Raise options. Subsequent players would also get the options of Call and Raise. To Call is to bet the same as what the previous player has bet. Raise action calls for raising whatever was the bet/call amount of the previous player, and can be calculated based on the value of the previous bet amount.

Every player participating in the hand should place equal amount of bet as the previous players (includes bets, calls and raises). Till the time all the players have placed equal amounts in the pot, the betting will continue. There is a limit on the amount and the number of bets a player can place during a betting round, which also would be considered during the hand. The numbers of bets for a particular round of betting has been mentioned below, please refer to the section on “Standard Rules” for the limits on the number of bets.

After the first round of betting is over, the Flop (the first three cards of the community) is dealt. The community cards are common to all the players participating in the hand.

The Second Round of Omaha 8:

After the flop and in each subsequent betting round, the first active player left of the button is first to act. The second betting round also limits the value of bets and raises to the lower limit of the stake structure. So in a $10/$20 value of each bet is $10 for the second round. When we say the bets are limited to $10, it refers to: a Bet (single bet) of the value of $10, so when a user places “BET” then it is $10, “RAISE” would be $20 – includes one additional bet and a call on the previous bet placed by a player. Bets can be placed, by playing any of the following options – Bet, Call and Raise. These options are available to each player depending on the action taken by the previous player. The first player placing the bet would get the Bet option (the player left to the Button). Other players will get the Call and Raise options only.

After this the fourth community card is dealt out – this is known as the Turn.

The Third Round of Omaha 8:

The third betting round starts again with the player left to the button, and bets and raises are limited to the upper limit of the stake structure ($10/$20 game, $20 would be the upper stake). When we say the bets are limited to $20, it refers to: a Bet (single bet) of the value of $20, so when a user places “BET” then it is $20, “RAISE” would be $40 – includes one additional bet and a call on the previous bet placed by a player. Bets can be placed by playing any of the following options – Bet, Call and Raise. Combinations of these options are available to the player depending on the action taken by the previous player. The first player placing the bet would get the Bet option (the player left to the Button).

After this the fifth community card is dealt out – this is known as the River.

The Fourth Round of Omaha 8:

The fourth (and final) betting round starts again with the player left to the button, and bets and raises are limited to the upper limit of the stake structure ($10/$20 game, $20 would be the upper stake). When we say the bets are limited to $20, it refers to: a Bet (single bet) of the value of $20, so when a user places “BET” then it is $20, “RAISE” would be $40 – includes one additional bet and a call on the previous bet placed by a player. Bets can be placed by playing any of the following options – Bet, Call and Raise. Combinations of these options are available to the player depending on the action taken by the previous player. The first player placing the bet would get the Bet option (the player left to the Button).

Some standard rules
A maximum of four bets, which includes one bet, and three raises are allowed for each betting round per player. The term cap is used to describe the final raise in a round since betting is then capped and no one can make another raise. Once capped, players will have the option of calling or folding only. Folding can be done at any stage of the game. The action of folding basically shows the player cards being moved to the dealer. The player from then on would not be considered as part of the game. He/she would not have any rights over any pots created on the table.

Apart from the fold option, a player could also get the option of “Check”, in which the player can pass his/her turn without placing a bet. This option would not always be available to the player, and depends on the actions taken by the previous player in the hand. The player HAS TO equal the amount of bet placed by any other players for each round in the hand.

Poker is typically played "table stakes", meaning only the chips in play at the beginning of each hand may be used throughout the hand. This means that the player cannot get additional funds from the cashier while he is in the midst of a game. The table stakes rule has an application called the "All-In" rule, which states that a player cannot be forced to forfeit a hand because the player does not have enough chips to call a bet.

Exceptions to the value of betting in each round:

A player who does not have enough chips to call a bet is declared All-In. The player is eligible for the portion of the pot to the point of his final wager. All further action involving other players takes place in a "side pot", which is unavailable to the player who has already gone All-In. When a player goes All-in, the pot currently at the center of the table, which has contributions from him/her as well, is treated as the main pot, over which the All-in player has rights. After the player goes all-in, all the new bets are placed in a side pot, over which only the contributing players have rights. The All-in player does not have any rights over the side pot. The side pot is then given to the next winning combination.

On the final round of betting, the player who bets first (or checks first if no one else bets) is required to show their cards first at the showdown. If they have the best hand, the remaining players may/may not show their cards as they wish. The aggressors’ hand is only turned over first if he was the last to initiate action on the river.

After the final round of betting, it’s time for - Showdown. This refers to the action of deciding who the winner of the pot is and display of the cards from all players (though this is optional for the player, he/she need not show the cards). Five cards of the total of hole and community cards (two hole cards and 3 community cards) are to be used for deciding on the winning hands.

On the final round of betting, the player who bets first (or checks first if no one else bets) is required to show their cards first at the showdown. If they have the best hand, the remaining players may/may not show their cards as they wish. The aggressors’ hand is only turned over first if he was the last to initiate action on the river.

There is no qualifying on the "High" side - the best high hand automatically wins half the pot and could win the whole pot. To win the "Low" side of the pot, however, you must qualify (which is why the game is named Omaha "8 or Better").

To qualify for Low: It takes a five-card hand with different numerical values from Ace through eight (with the Ace being the lowest) to qualify for the "Low" half of the pot. The best "Low" hand is A, 2, 3, 4, 5 (also known as the "wheel" or "bicycle"). The winning "Low" hand goes to the player with the lowest high card. For example, a player with a 2,4,5,6,7 would have a better "Low" hand than someone with an A,2,4,6,8. If two or more players have the same high card, the player with the second lowest card (or third, fourth, or fifth if necessary) in their hand wins the low side of the pot.

There is a set rank of cards, which is used for deciding the winning combination. To view the various ranks that are possible, click here

Ties: In case two or more players "tie" for one side of the pot, they will split that half into equally divided portions. If there is an odd chip(s), it will go to the person(s) closest to the left of the "button". (One player winning the "High" side and two players who ties for the "Low" side is not uncommon in Omaha 8 or Better.)

Some things to Remember
1) Straights and Flushes do NOT count against you when qualifying for "Low".
2) You are permitted to use different cards in your hand for the "High" side and different cards for the "Low" side or the same cards for both the "High" and "Low" sides. In a split pot, any leftover odd chip goes to the "High" side of the pot.

Key to Remember: To determine your hand(s) in Omaha 8 or Better, you MUST play two of your four "down" cards with three of the "up" cards (community cards). You may play different cards for the "High" and "Low" sides.

The suit order of the cards is not taken into account while deciding on the winning cards. Normally, should poker hands be absolutely identical in ranking, the rule of poker pot distribution will be split evenly between the two or more winning players. This applies to both play money and poker for real money.

For all the four rounds of betting, the house based on set rules collects a commission, which is known as the rake in poker terminology.
