A. Omaha, also known as Omaha Holdem is a community card poker game similar to Texas Holdem. In this online poker version, players are dealt four private (hole) cards each. Five community cards are dealt face up on the table. In Omaha, players have to use exactly two of their hole cards together with exactly three of their community cards to make the best of five card poker hand.
In Omaha, the betting starts with a small blind, to the left of the dealer that is followed by a big blind. These are compulsory or forced bets that must be made before seeing one's cards. Play runs clockwise starting from the blinds, with each player having the option to fold, call, or raise. The blinds are "live", meaning that they may raise in quantity when the action gets back around to them.
Again the next 3 cards are dealt face up in the middle of the table; this is called the "flop". A round of betting follows, with action starting from the first blind, i.e. immediately to the dealers left. Another card is dealt face up (called the "Turn"), followed by another round of betting, again beginning to the dealer's left. Then the final card (the "River") is dealt which is followed by the final round of betting.
In Omaha Hi each player makes the best five-card combination to win the pot. Players have to ensure to use exactly 2 hole cards and 3 board cards. No more any less.
