Yeah, that's the funny thing about Omaha...there aren't any dominant hands pre-flop. Whereas with Hold 'Em, if you pick up AA, AK, KK, etc. even if you miss your hand...heads-up, or with a narrowed field, your hand still has a chance of holding up...with Omaha Hi for example, AAKK double suited (I'm presuming this is the best hand, I don't really know), is great...until you get a rainbow flop without an Ace or a King, then you have to fold it straight up.

But yeah, basically, the best hands in Hold 'Em can sometimes stand up without help...Omaha hands can't.

About the best starting hands in Hi/Lo...I've just been looking for articles for Omaha, and couldn't find any, but i'd say AA23 does sound like the most powerful hand. With Stud Hi/Lo I reckon 345 or rolled up trips are the best starting hands.

I used to be a predominantely Hold 'Em player...but the more you play these other games, the more addictive they are.
