Omaha - Rules and Information:

Omaha Hold ‘em is played with a standard 52-card deck, with each player receiving four down cards as their initial hand. There is a round of betting after these cards have been delivered. Three board cards are then turned face-up(which is called "the flop") and another round of betting occurs. Another card is turned face up, followed by a round of betting. A final board card is then turned up and a final round of betting ensues. These five board cards are "community cards" and after the final round of betting has been completed, a player must use a combination of two cards in his hand and three cards from the board to determine his best hand.

Omaha uses a flat disc called a "Dealer Button" to indicate the player, who in theory, deals the cards for that pot. The button (player with the Dealer-Button) is last to receive cards on the initial deal and has the right of last-action on all betting rounds except the first. One or more "blind" bets are used to stimulate action and initiate play. "Blinds" are posted before the player looks at his cards. "Blinds" count as part of that player’s bet, unless the structure for a specific game or situation requires part or all of a particular "blind" to be "dead". "Dead" chips are not part of a player’s bet and are taken into the center of the pot.

"Blinds" are posted by players in consecutive clockwise order from the Button. Action is initiated on the first betting round, by the player on the immediate left of the person who posted the furthest "blind" clockwise from the Button. On all subsequent betting rounds, the action is started by the first active player clockwise from the Button.
