Omaha
Omaha is similar to Texas Hold'em in many ways. One of the difference is that the player is dealt four pocket cards instead of two. There is also Omaha played with five and even six hole cards but the most common type of Omaha is played with four hole cards. During the game five cards will also be dealt on the table visible for all players. These cards are called community cards. Another difference between Texas Hold'em and Omaha is that the best 5-card-hand in Omaha most contain exactly two of the players pocket cards and exactly three of the community cards. This means that if a player is dealt four aces he can only use two of them create a hand.

The Blinds
In Omaha a dealer button is used, just like in Texas Hold'em, to see where the cards should be dealt from. This dealer button is moved one step to the left after every round. The small and the big blind are posted by the two players left to the dealer button.

Preflop
When the blinds have been placed on the table, each player is dealt four cards faced down. These cards are called pocket or hole cards. The player to the left of the big blind starts the betting round by calling, raising or folding his cards. The first betting rounds are finished when all players have either called the big blind or folded.

The Flop
When the first betting round is complete the dealer deals 3 cards on the table faced up. These cards are called the flop and can be seen by all players. The player to the left of the dealer button starts the second betting round by either checking or betting. If a player bets into the pot the other players have to decide if they want to call, raise or fold. The second betting round is over when all players have either put an equal amount in to the pot or folded.

The Turn
When the second betting round is complete the dealer puts out one more card faced up on the table. This card is called The Turn or 4th Street. This card is also showed to all players at the table. The third betting round works the same way as the second round. The third betting round is over when all players have either put an equal amount in to the pot or folded.

The River
The dealer puts out the last and 5th card called the river or 5th street. This card is showed to all players and can be used by any player to combine a hand. A fourth and last betting round occurs and works exactly the same way as the second and third betting round.

Showdown
After the fourth and last betting round, it's time for the showdown where the players still left get to show their hands. The player must use two of his pocket cards and three of the community cards to creat the possible 5-card hand. The player with the best combination wins the pot. If both players have equally good hands, the pot is split.
