Tips to play Omaha Hi/Lo
Play to Win: The spirit of the game is in winning it, so after the flop, if your high hand is not a sure winner and might have to split with the low, or even if you are playing for low but don't stand a decent shot at the high hand, it's a good idea to check/fold and get out early.
Slow play most Omaha hands: Early raises are risky unless you know you can't lose.
Avoid playing middle suited connectors. Hands like 8h 9h spell bad news in high-low split. In order to make the high end of a straight, you need to catch the cards that will also qualify low hands. To play these you also need a suited ace or an A2.
Do not overbet A2, A3 and 2 3 nut lows. You could end up getting quartered as these are often shared with another player. If there are two playing the same nut low and one going high, every bet you make contributes 1/3 to the pot that will only pay you 1/4 back. It makes sense to check around. Fast play, here will make you money if there are three or more other players with either high or losing low hands.
Beware of uniform flops, like 8 7 6, they could easily turn into straights that can overtake your high pair trips, or other good hand.
Watch out for Suited Flops that can make a completed flush. Hold the nut in that suit, or have trips or two pair that can fill up.
Check the raisers chips. Players that are close to all-in often rush the betting just to get all their chips in a sink-or-swim last hand.
Study your opponents, especially when you are not playing hands and can pay careful attention. Look for any "tells" (give away mannerisms) that disclose information about their hands etc.
Get caught bluffing once in a while, as it varies your play. You win pots that you don't deserve when your bluff works.
