In Omaha your task is to create the best possible five cards from the nine available (four hole cards and five community cards). The key point to remember is that that you must use two and only two of your hole cards in forming this hand.
Let's take a look at how this works in practice.
Hole Cards | Board Cards |
Here your best hand is no pair, Ace-high. Your best five-card hand is A-K-Q-J-9.
Hole Cards | Board Cards |
This time you have a pair of Sixes, Ace kicker. You can use the two Sixes on the board to make a final hand of 6-6-A-K-Q.
