Playing in Omaha is all about getting on top, very similar to how it is in Hold’em. But, there’s a difference! In Omaha, when you bit big, essentially what you’re doing is declaring to everyone on the table that you have a good hand, which then proceed accordingly. If you’re betting high on a straight, the others will figure it out and will then analyze their moves according to your strategy, and will either play you or sit out. Either case, you’ve made it very evident that you have good cards.
Betting is very interesting in the way that at the same time, a player can show both toughness and vulnerability. You never know what to expect. Even when you think you have good cards, you can still be outbid and lose. In the flop/post-flop Omaha play the concept is that before someone beats you at the bet, make sure you win the pot.
Pre-flop betting is important in Hold’em since it eliminates people with bad a card which is why Hold’em is a game which can accommodate only players with medium to good cards. However, even those cards are not unaffected by cards such as A5 or K9. Nothing stings more than slow playing with a couple of cards and then realizing that an opponent flops a strange pair of cards which is higher than your pair, eliminating your hand. So it doesn’t matter if people know you have high cards – that may make them sit out later on in the game.
But Pre-flop betting is not recommended in Omaha play. A strong pre-flop bet indicates that the player holds good cards, either A’s or K’s or a pair of suit. When you’re well informed on the tactics being used by the others, you can decide your game play accordingly and realize who has the high Ace flush. If you fold when in that position, you may land up saving a lot of money. If the pre-flop better tries that again, his second hand will not be so lucky because people will know that he has good cards.
Keep your strengths in check, don’t reveal them. Just like in Hold’em, game position is it. If your hand is strong and you’re in a strong position you must do all it takes to save your hand, but that will transmit information to the opponents. If, on the other hand, you’re late in betting with the same cards, your opponents will not be able to figure out your hand.

Like in Hold’em, Omaha is also conducive to slow playing and check-raises, which are both very powerful in winning.  However, bear in mind that slow playing can be very tricky when you have a flush or a straight, as you can potentially be beaten. Check-raising can be successfully employed with you are strong in your position, hold on to the straight nut and are certain that the players sitting after you will bet and then raise.

The players you’re playing against actually depend whether you’re going to do check-raising or not. Loose-aggressive players sit out when they have good upper hands, or call raises. The pros know that check raises are risky, since the better players will not strategize them, unless the hands they have are very strong.
