Here are some important probabilities in Omaha that returns in different situations. Knowledge about probabilities will help you to better evaluate situations in poker. You will , for example, know when you should call and when you shouldn't, and, vice versa, know when to fold and when the odds are in your favor.

  1. The next two tables show the probabilities in 5-card stud with one wild card. The first table is for a partially wild card that can only be used to complete a straight, flush, straight flush, or royal flush, otherwise it must be used as an ace (same usage as in pai gow poker). The second table is for a fully wild card.
  2. The number and probability of a royal flush alone is 4 and 0.0000015. 3The error in the sum of the probabilities is due to rounding. In similar tables to come, the symbol. will indicate the same thing.
  3. It looks like you're trying to calculate the odds of flopping a flush, not a flush draw. In this case the odds of the events all happening is a multiplication of the odds of each individual event (11/50.10/49.9/48 so 0.84%) OP is asking the odds of flopping a flush draw, so 2 suited, one unsuited out of the three in all combinations.

Starting hands

You have a flush draw on the flop with 9 outs. You will improve it on the turn: 9.2=18% and real poker odds are around 19%; You have a straight draw on the flop with 8 outs. You will improve it on the turn: 8.2=16% and real poker odds are around 17%; You have two over cards on the turn with 6 outs.

There are many starting hands in Omaha (16.432 if not all suit combinations are counted), which makes it difficult to get an overview. Table 2 will hopefully increase that overview a bit.

The best Omaha hands are less bigger favorites against an average hand compared to Texas Hold'em.
In Texas Hold'em, common knowledge is that A-A is very big favorite against all other hands. In Omaha, A-A as a part of a hand is far from that strong. In general, an A-A-x-x hand versus a random four-card hand is a 70-30 favorite in average (if all the starting hands that are normally folded are excluded, the A-A-x-x hands will be even less favorites).

Made hands versus draws

A typical feature in an Omaha Hi game is a set against a hand with several drawing possibilities. The made hand will not be a very big favorite (sometimes it is an underdog), so the recommended strategy is to play fast and bet/raise the pot in these situations.

Poker Odds Flop Flush Draw

Since that many cards are in action, there are often combined possibilities, which makes it hard to give general percentages. A hand with a flush draw has mostly something else, like a pair or a straight draw as well.
