Understand the Omaha poker rules before you play
Popularly most of the poker variants are played for high rank hands. The high-lo game supports one to play the best high or best low hand towards splitting the pot. Sometimes you can see that you will be able to make both the high hand and the low hand, thus eventually scooping the pot!
Understanding Omaha poker rules before you play the high-low games is quite necessary so that you do not fold your hands when you have low hands; if you are going to have the best low hand chances are that you can split half the pot, provided someone else does not have an equally qualifying low hand. Even if someone else is going to hold an equally good hand you can at least expect to split quarter of the pot! And, that should sound quite fair rather than losing all that you have invested!
Omaha poker rules relating to the 2 from your pocket cards is very important and you cannot just play the boards from using just one card from your hand to make the winning. There are going to be many times that you will have a card that can make the best possible hand with 4 board cards, but such is not allowed. The best of the hands are not considered, unless there are 2 cards used from your original pockets.
