Let's face it: the folks who became poker players are the ones who didn't share their toys well as children. Splitting a pot is an almost obscene concept to most players.
In Holdem, your biggest fear is probably that Stanley from New York didn't fold when he should have, and might catch a lucky card on the river. In Omaha, you have much more territory to defend.
You see potential, you bet based on that potential, and you either win big or go home wondering how to explain the big hole in your bank account to your spouse.
A common mistake that a number of players make is that they completely ignore the high hands and focus almost exclusively on making the best low. The reason for this is that flop often comes down with an abundance of low value cards that are more of a help when making a low hand. Settling for a split pot is not a very good way to make money. When the flop produces three or more high value cards, creating a decent low becomes almost impossible, so a high hand may very well scoop the pot.
When playing the Turn in Omaha High-Low, there are definitely some things you should avoid doing in order to not wind up a casualty of this aspect of the hand.
