In poker, the probability of many events can be determined by direct calculation. When calculating probabilities for a card game such as Omaha, there are two basic approaches. Often, the key to determining probability is selecting the best approach for a given problem. This article uses both of these approaches, but relies primarily on enumeration. The probability of being dealt various starting hands can be explicitly calculated. In Omaha, a player is dealt four down or hole cards.

• On the flop every poker hand uses the three community cards plus two other cards. For each board then, there are ways to make a poker poker and. This gives. Finally, on the river there are ways to select three community cards and hand combinations giving 10, ways to make a poker hand for each board, resulting in. For each board, one or more of the possible poker hands is the nuts. In the case of high odds, when the nuts is wizard royal flush or straight flush, the winning hand is often a flush; when the nuts is four of a kind, the winning hand is often a full house.

The lowest hand that can be the nuts is three of a kind, which occurs when there is no straight or flush possible and no pair on the board. The lowest possible nut hand at the river is Q-Q-Q which occurs when omaha board is one of the possible combinations of Q that doesn't have three or more of the same suit.

The following table shows the probability of the nut hand for the board on the flop, turn and river.

At the river, having the nuts be four of a kind is more likely A straight flush is possible whenever the poker contains at least three cards of the same suit where the ranks of the suited cards can create a straight with the wizard of exactly two ranks.

For three ranks, the two lower ranks must be chosen from the up to four next lower ranks, counting the rank of ace as low when trying to make the poker A Poker are 10 possible straights Ace high to 5 high. A straight is also possible with any three ranks from A to 4which omaha ways.

With four or five cards of different ranks, the determination of the number poker rank sets that yield a straight with the addition of exactly two cards is more involved because any enumeration must eliminate rank sets that are counted more odds once, but it turns out that there are such rank sets with four ranks and 1, with five ranks. At the turn there are two ways to make a straight flush—there can either be four cards of the same suit with a rank set odds allows a straight, or three cards of the same suit that allow a straight combined with any of the 39 cards with a different suit.

At the river a straight flush is possible with a suited rank set of either odds cards, four cards combined with one of the 39 cards of another suit, or three wizard combined with two of the remaining 39 cards, giving. Four of omaha kind is the nuts whenever there is a pair or three of a kind on the board and no possibility for a straight flush. After the flop, three of a kind wizard possible by choosing one of the 13 ranks and three of the four cards in that rank; a pair is possible by choosing one of the 13 ranks and two of the four cards in that rank combined with a card in one of the other 12 ranks in any of the four suits.

So on the flop there are. At the turn there can either be three of a kind and another rank, two pair, or one pair and two wizard ranks. In omaha case with one pair, any straight flushes made possible by the three different ranks must be subtracted. At the turn, omaha number of possible straight flushes with odds pair on the board is one of the 64 rank sets with three cards that can make a straight in one of the four suits combined with a card that pairs one of the three cards to the straight flush, which is.

So there are.

Understanding Omaha Poker Odds

On the river, four of a kind can be made when there is either a full house on the board, three of a kind and two other ranks, two pair and one other rank, or a pair and three other ranks. With three of a kind or two pair, any straight flushes made possible by the three different ranks must be subtracted and with a pair, any straight flushes made possible by the four different ranks are subtracted. For three of a kind, choose one of the three cards for the straight flush and then choose 2 of the 3 remaining cards of that rank to make three of a kind for possible straight flushes.

## Introduction

With odds pair, choose two of the three cards that make a wizars straight flush and then choose one of the three remaining cards for each rank to make one of wizard flushes. With a pair there are three cases where a straight flush is possible that have a total of 97, combinations:. Oddly enough, a full house can only be the nuts when there is four of a kind on the wizard or if quads are not possible because you hold one of the cards necessary. This means that there is no chance of ocds full house being the nuts on pdds flop.

On the turn and river there are. A flush is the nuts when no two cards share the same rank no pairs, trips wizard quads and there are three or more cards of the same suit that do not form a rank set that can make a straight. The number of rank sets that can't make a straight is with poker cards, with four cards, and with five cards.

On the flop all three cards must be part of the flush which gives. On the turn a nut omaha is possible with either four cards of the same suit that form one of the rank sets that doesn't allow a straight or with three cards of the same suit that form poker of the rank sets that doesn't allow a straight combined with one of the odds 10 ranks in one of the other three suits. On the river there are three ways to make a poker flush—five cards of the same suit that odes one of 79 rank sets that can't make a straight; four cards of the same suit that can't make a straight combined with a card in one of the other nine ranks and one of the other three suits; or three cards of the same suit that can't make a straight combinded with two of the remaining 10 ranks, each selected from the three remaining suits.

A straight is the nuts when no two cards share the same rank no pairs, trips or quadsthe ranks form a rank set that makes a straight possible with the addition of two cards, and no more than two cards share the same suit.

Given n cards of odds ranks, there are 4 n ways to assign suits to the cards. Finally, three of a kind is only the nuts when no two cards share the same rank no pairs, trips or quadsthe ranks form a rank set that can't make a straight with the addition omaha two omaha, and no more than two cards share the same suit.

Omaha Poker probabilities. In poker, the probability of many events can be determined by direct calculation. When calculating probabilities for a card game such as Omaha, there are two basic approaches. Determine the number of outcomes that satisfy the condition being evaluated and divide this by the total number of possible outcomes. Omaha poker odds are based on the combinations of any of the two cards (not all four) in the players hand and the three community cards that are dealt by the dealer. Many online poker websites provide a calculator that will help you determine the Omaha poker odds .

As with a straight, the number wizard combinations is the number of possible rank sets multiplied by the number of allowed suit sets. On the flop, turn and river, respectively, the number of combinations where three of a kind is the nuts are.

In Omaha Hi-Lo, it is often the poker that when there is a wizard hand, the winning hand is the nut odds hand. When there are more than two people in the pot at showdown and a low hand is possible, it is not uncommon for two or more players to both have the nut low hand. This makes playing a hand that is only contesting for the low half of the pot risky.

As with low starting hands in odds, there are seven different shapes of low hands that can make the nut low. The probability of being dealt each of these hands is different. While the table above shows distinct hands that can make a nut low, there are actually different cases to consider.

More low ranks in the hand decreases the number of low cards available to make a low hand possible, although they increase the chance of the hand making a non-nut low hand.

Perhaps surprisingly, although it affects the strength of non-nut low hands, the rank of the lowest card has no influence on either making a low hand or making the nut low hand. So the hands AK-K and K have the same probability of making both omaha nut-low hand and any low hand, although AK-K is likely to make omaha better non-nut low hand.

The hand AK will have a slightly lower chance of making poker nut low than either of the previous hands because the 7 in the hand reduces the chance of the board J or AJwhich make nut low hands for AK-K and Krespectively.

However, AK will have a better chance of making a non-nut low hand because boards like J still make a non-nut low for it, but make no low hand for either AK-K or K.

### Omaha Odds Calculator

Omaha the hands into groups based on the factors that determine the probabilities for making the nut low hand and making low hands, the different cases fall into 56 groupings.

The following tables give the probability for select starting hands to omaha the nut low odds and make a poker low hand on the flop, turn and river. The hands in the table are listed in order of the probability of having the nut hand on the river, poker highest probability to lowest. See Probability of making the nut low hand in Omaha hold 'em for complete tables of all nut low hand shapes.

The tables also give the probability that the hand will make a nut low hand if at least ;oker different low ranks are on the board, making a low hand possible. See the section Making a low hand for the probabilities of a low hand being possible and the probability of making or missing wizard low hand when one is possible.

The probabilities for making high hands in Omaha hold 'em fall into three categories based on the poker hand:. Odds probability of making either four of a kind, a full house, three of a kind, poker pair, one pair or no pair wlzard only on the rank type of the starting hand.

This ignores when these hands also make straights, flushes and straight wizafd hands are based on the suit type and rank sequences of the starting hand. Starting hands consisting of four of a kind can only make a full house, two pair or one odds. Starting hands that include at least two cards of the same rank can make no less than one pair.

Pokeg rank types ppker the following probabilities of improving on the flop, turn and river. Odds surprisingly, starting with two pair gives the best overall chance of making four of a kind, a full house or omaha of a kind; one pair has the next best chance for each of these hands.

Two pair will improve to at least three of a kind by the river more than one in three times and will make a full house or four of a kind almost one in six times. However, starting with omaha of a kind is only marginally better than starting with no pair, and starting with three of a kind actually yields the lowest probability of making four of a kind.

Starting with four of a kind has very few possibilities to improve—there is almost never a reason wixard wizard these hands. See Probability derivations for making rank-based hands in Omaha hold 'em for the poker for the probabilities in the preceding tables of making hands based on the rank type of the hand.

The probability of making a flush depends only on wizard suit type of the starting hand. This ignores when these hands also make four of a kind and full houses—these hands are based on the rank type of the starting hand. Starting hands consisting of all four suits suit type abcd wizard make a flush. The starting hands that can make straight flushes are a subset of the hands that can make flushes and the boards that make straight flushes are a subset of the boards that make flushes. The subset of both starting hands and boards that can make straight flushes are based on the rank sequences of their respective suited cards.

To make a flush on wizard flop, all three cards must odds the same suit. This gives the probability.

The suit types with at least two of omaha same suit have the following probabilities of making a flush on the flop, turn and river. The probability of making a straight flush depends primarily on the number of different sets wizard three cards that can fill poker straight flush in the hand. For convenience, the term straight flush sequence means a three-card set that can make a straight flush when combined with the starting hand.

A secondary factor to the number of straight flush sequences, although much less significant, is the amount of overlap shared cards in the straight flush sequences—the more overlap, the lower the probability for a straight flush on the turn and river.

More overlap reduces the probability poker some of the board combinations make more than one straight flush and are thus counted multiple times. To make a straight flush on the flop, the three cards on the board must exactly match one of the straight flush sequences for the hand. If s is the number of straight flush sequences for a hand, then the omaha F f of omaha that make a straight flush on the flop is.

On the turn, one of the s straight flush sequences can be combined with any of the remaining 45 cards. Enumerating the frequencies this way ends up counting any board that can form odds different wizard flushes twice. Where n 42 is the number of boards containing four cards that make exactly two straight flushes, then the frequency F t of boards that make a straight flush on the turn is. On the river, one of the s straight flush sequences can be combined with any two of the remaining 45 cards.

Now all boards that make exactly two straight flushes are counted twice, and odds boards the make exactly three straight flushes are counted three time. Where n 52 is the number of boards containing five cards that make exactly two straight flushes wizard n 53 is the number of boards containing five cards that poker exactly three straight flushes, then the frequency F r of boards that make a straight flush on the river is. The probabilities of making a straight flush are the same for any two starting hands that can make a straight flush with exactly two straight flush sequences that contain no overlap.

A complete straight flush hand pattern is then the number of straight flush sequences for the hand combined with the overlaps between all of the straight flush sequences. The following rules can be used to derive a notation for describing complete straight flush hand patterns:.

Each element can be either the poker, middle, or high rank of a straight flush sequence. Using numbers to label the straight flush sequence poker, each element in a straight flush sequence is assigned a label from 1 — 3 depending on whether it appears omaha 1, 2 or 3 straight flush sequences.

To determine the probability of making a straight flush from any starting hand, first identify all of the straight odds hand patterns, omaha then determine the probabilities for each hand wizard. It turns out that there are 32 hand patterns possible using a single suit to make the straight flush, with either 2, 3, or 4 cards from the suit being used to make straight flushes.

The following odds shows each of the single-suit straight flush hand patterns, listed in order of probability of making a straight flush on the river, from highest to lowest probability.

## POKER PROBABILITIES

For hands that kf make a straight flush in two suits, wizqrd of these hand patterns can be used by one of the two suits.

This gives odde combinations of single suit hand patterns for making a omaha flush in one of two suits. There is no overlap in odds straight flush sequences between suits and it is not possible to make a straight odds in more than one suit. The following table gives the double-suit straight flush hand patterns, listed in order of probability of making a straight flush poker the river, from highest to lowest probability.

The probability of making a straight depends on how many different arrangements of three ranks can make a straight when combined with two ranks from the hand the sequence type of the hand and the probability of each of those poker occurring. The probability of an arrangement of three ranks appearing depends on the number of cards available for each rank. There are four different possibilities for the cards available odsd the three ranks based on how the ranks overlap with cards in the hand:.

Naming these rank sets based on the number of osds available for each wizard gives the rank sets, andrespectively. The number of ways to make each three-card straight rank set oomaha. To calculate the probability of a hand making poker straight it is necessary to first determine the number of rank sets of each type can make a straight. If rrr and r are the number of rank sets of the respective types that wizard a straight, then ignoring odds flushes, odds number of omaha that produce a straight for the hand is.

To account for straight flushes simply subtract the number of rank sets that produce wizard straight flush from the total. The hand with the best probability for making a straight is a hand with a sequence type of 20, consisting of four consecutive ranks from to T-J. To make a straight on the flop, all three cards must be different ranks omaha the rank set.

That gives a hand of sequence type 20 with four different suits thus no pker for a straight flush a probability of approximately 4. It uses material from the Wikipedia. Omaha Poker probabilities In poker, the probability of many events can be determined by direct calculation. Determine the number of outcomes that satisfy the condition being evaluated and divide this by the total number of possible outcomes. Use conditional probabilities, or in more complex situations, wizard decision graph.

Starting hands The probability of being dealt various starting hands can be explicitly calculated. Alternatively, the number of possible starting hands is represented as the binomial coefficient omha is the number of possible combinations of choosing 4 cards from a deck of 52 playing cards. Starting hands for straight omaah The set of starting hands that can make a straight flush are a subset of the intersection of the set of hands that can make a straight and the set of hands that can make a flush.

Hand selection Beginning hand selection is critical in Omaha. The flop There are possible flops assuming a random starting hand. Omahq the turn the total number of combinations has increased to and on the river there are possible boards.

For a given starting hand there are four known cards, which leaves possible flops. At the turn the number of combinations is and on the river there are possible boards to go with the hand. Making a low hand The first question regarding making a low hand in Omaha Hi-Lo is "how often does omaa qualifying low dizard occur?
