Omaha is considered, by some, to be the hardest game of Poker to master. Of all of the different games of Poker, Omaha is for many the hardest to learn to play and the hardest to bluff in. It is played most often at fixed limits, like Texas Hold'em and pot limit.
The game of poker involves both luck and skill. In the short term, luck can play a significant role in determining the outcome of individual hands or sessions. However, over the long term, skill becomes a more important factor in determining success in poker.
