Omaha 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. 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 player to the left of the small blind is required to post the big blind, equal to the lower stake limit. All the blinds in Omaha 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, 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 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 have equal amounts of money bet as the previous players. Until 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 (four bets for limit games).
After the first round of betting is over, the Flop (the first three community cards) is dealt. The community cards are common to all the players participating in the hand.
After this the fourth community card is dealt; this is known as the Turn. The betting limits now increase to the higher limit of the stake structure for the remainder of the hand. After betting on the turn is complete, the fifth and final community card is dealt; this is known as the River. Betting continues as on the turn.
Once all the bets have been made, there are two possible outcomes: either all the players but one have folded (and hence that person wins the pot), or the remaining players reveal their hands and the best hand wins the pot.
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.
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.
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.
After the final round of betting, it’s time for the 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.
If two or more hands are the same ranking, the winner is the one having the higher cards. For example, a Flush with an Ace high beats a Flush with a King high. If the poker hands remain tied, then the highest card not being held in common (the kicker) determines the winner.
The suit order of the cards is not taken into account while deciding on the winning cards.PartyPoker.com follow standard rules of poker. 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. If there is an odd chip, the winning player to the left of the button/dealer will receive it.
The game play remains same for both No-Limit and Pot-Limit Omaha game with a few exceptions to the rules mentioned above:
In Limit Omaha a maximum of four bets is allowed per player during any betting round. This includes a (1) bet, (2) raise, (3) re-raise, and (4) cap, but in No-Limit and Pot-Limit there is no limit to the number of raises that a player can make. The only criteria being that you cannot raise yourself, (i.e. if a player bets during a betting round, then that player would have to be raised by another player in order for him/her to be able to re-raise). If all the other players in the hand only call or fold, the player would not get an option to raise, because the last raise was done by him/her.
