Omaha can be tricky at times and it probably best to get used to the Omaha hi games first before diving into the Hi/Lo part as that can really confuse a newer player.

- Hi/Lo (8/b)
The best piece of advice i ever heard on Hi/Lo was - only look for the Hi hand.
Basically if you think you have a good Lo hand and put a lot into the pot, you may only win a 1/4 of the pot if you have to share, so in fact you'll end up losing chips .
Also some times there isnt a winning Lo hand so the Hi will always take the chips.
Sorry if this is a bit confusing but once you begin to see the light it is a really good game.
