Omaha Sit N Go Short-Handed Play
For the most part, the transition from Hold 'Em to Omaha in the early and middle stages is pretty easy simply because many players will employ the same general strategy in the Hold 'Em Sit N' Goes that they play. However, the late strategy is going to be quite a bit different simply because of the fact that each player starts with four cards instead of two, so while the general strategy might be the same, the particulars are going to be different.
When you are playing short-handed, as you should already know from Hold 'Em, drawing hands lose their importance and are replaced by high-card hands as being the hands that you want to enter pots with. This means that any A-K-X-X hand is usually a great hand in short-handed Omaha play and depending on the situation and how tight your opponents are playing any A-X-X-X might be good as well. Of course, the higher the complimentary cards in the hand the better because if you have A-Q-10-9 and the flop comes Q-X-X, then you are still in business pretty big time.
More important than the hand combinations however is the way in which you bet. You want your opponents to fear your raises, because if you take the initiative and make them make decisions about whether to fold or call, you are going to have the advantage over the long run. How many times have you longingly looked at you're A-2 off-suit only to throw it away to a raise three-handed because you wanted a better place to get your chips in during a Hold 'Em Sit N' Go? Well, the same psychology applies to Omaha, so raise big and raise often. Make your opponent constantly make decisions that involve large portions of their chip stacks and you will find that your own path to victory will become easier than theirs.
While being aggressive is always good, it is important not to be reckless. Don't make four or five raises in a row with total crap, because eventually somebody is going to pick a hand that they fancy racing with and you could find your tournament ending pretty quickly if that happens. Selective raises that bunch together when the rest of the table is playing tight and sitting back and waiting for hands but raising with them when you get them is the way to win Omaha Sit N' Goes from a short-handed position.
