The first times i've played to omaha, somebody explains me that omaha is a game for nuts.. straight and flush are some things which offen occur
When you play to omaha a set is like a middle pair in hold'em, a pair means nothing.
You'll often draw on Omaha, and especially on hi-lo, so you have to be agressive
It's a good lesson for hold'em I think, but it's not at all a game for noobs
