Starting hands

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.

Exemple of a double suited hand: Q♥ A♥ 2♦ K♦
Exemple of a rainbow hand: Q♥ A♣ 2♠ K♦
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.

Table 3. **Made hand versus drawing hand**
Situation	Percent
Top set against flush draw	70%-30%
Middle set against flush draw	70%-30%
Top set against flush draw + two pairs	68%-32%
Set against wraparound straight draw	52%-48%
Set against double wraparound straight draw	53%-47%

No decimals are used. The numbers are only approximal.

Comments

Factors that can affect the odds are for example blocking cards.

Flush draws versus straight draws

In Omaha, hands with flush draws are often more likely to win than straight draws.

Table 4. **Drawing hands**
Situation	Percent
Flush draw against wraparound	60%-40%
Flush draw against double wraparound	55%-45%

No decimals are used. The numbers are only approximal.

Comments

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.

Games Supported

Generic Syntax is currently available for all games.

Generic Syntax may also be used to specify the board and dead cards.

Ranks and Suits

The standard ranks are 'AKQJT98765432'.
The standard suits are 'shdc'.
Suit variables are 'wxyz'. See the examples below for how these work.
All other letters not listed above are rank variables. 'R' for Rank, 'O' for Other rank, and 'N' for aNother rank are reasonable choices. See the examples below for how these work.
'*' is the wildcard rank, and means 'any rank'.

Here are some example 4-card (omaha) ranges using only the above:

AsKhJd2c- a specific hand where all cards are known.
AA- a hand with at least two aces in it.
AxAyxy- double-suited Aces.
sshh- a hand with two spades and two hearts.
wxy- a hand with at least three suits.
****- a completely random hand. This can be written more simply as '*'.
RRON- A hand with one pair and two non-paired side cards.
RxRyOxOy- A double-suited hand with two pairs in it.

Percent of Hands

ProPokerTools has its own ranking of hands for omaha, omaha hi/lo, hold'em, five-card omaha, and five-card omaha hi/lo. Here are a few examples of how to generate ranges using these rankings:

15%- The top 15 percent of hands (full-ring)
5%-10%- Hands between the top 5 and top 10 percent of hands (full-ring)
1%-100%- All hands

The default rankings are for full-ring games. Also provided are rankings for 6-handed games. To specify the 6-handed rankings, simply add '6h' after the percentage sign:

15%6h- The top 15 percent of hands (6-handed)
5%-10%6h- Hands between the top 5 and top 10 percent of hands (6-handed)

Combining Ranges

There are three ways to combine multiple ranges.

Use ',' (read as 'or') to get the union of two ranges. For instance, in hold'em, 'JJ, AK' means 'Jacks OR Ace-King.'
Use ':' (read as 'and') to get the intersection of two ranges. For instance, in hold'em, 'xx:15%' means 'hands that are suited AND in the top 15% of hands.'
Use '!' (read as 'not') to get the difference of two ranges. For instance, in omaha, 'AA!AAA' means 'hands with two aces NOT three aces.'

Note that all three combinators (',', ':', and '!') can be used together. For instance, in omaha, 'AA:xxyy, JJ!JJJ, KK' means 'double suited aces or a hand with exactly two jacks or a hand with at least two kings.'

Rank Spans

Rank spans allow you to specify cards that vary from a start rank to an end rank. This is easier explained with a few omaha hand examples:

KQJT-T987- Equivalent toKQJT,QJT9,JT98,T987
AAJT-AA87- Equivalent toAAJT,AAT9,AA98,AA87

It is possible to use multiple rank spans in the same hand if they are enclosed in square brackets. For instance:

[A-Q][J-T]23- Equivalent toAJ23, AT23, KJ23, KT23, QJ23, QT23

Furthermore, you can use a trailing plus or minus to indicate ascending or descending ranges:

T8+- Equivalent toT8,J9,QT,KJ,AQ
664-- Equivalent to664,553,442

Finally, suits and suit variables are allowed, as long as both sides match:

TsJs-KsQs- Equivalent toTsJs,JsQs,QsKs
[Kx-Jx]x- Equivalent toKxx, Qxx, Jxx

Rank and Suit Lists

Occasionally, you want to have a card match a particular set of ranks, suits, or cards. Here are some examples:

[2,3,4]- Equivalent to2-4
[2,4,6,8,T][3,5,7,9]- A hand with at least one odd and one even number card.
[As,Ah,K]K- Equivalent toAsK, AhK, KK

Card Order

Card order is preserved for games where the order of cards is significant (stud, stud-8). Card order is ignored for other games (hold'em, omaha, omaha-8). Card order is also preserved for flop game boards on the turn and river.

Card order in Stud Games

In seven-card stud, the order of the cards as they come out is significant except in the case of the first two cards. For instance, 'KsJhTd' and 'KsTdJh' are NOT considered the same hand. 'KsJhTd' and 'JhKsTd' ARE considered the same hand, because the order of the first two cards is not considered significant. When combining ranges, card order is respected for cards on third-street and beyond. For instance, 'KQJ:xxy' implies a stud hand with a suited king-queen in the hole and an off-suit jack showing (an equivalent way to write it wold be 'KxQxJy').

Card Order in Flop Games

There is no concept of card order in generic range syntax for Hold'em and Omaha. For instance, in Hold'em, 'KJ:hd' translates directly to 'a hand with a king and a jack AND a hand with a heart and a diamond'. As such, it is equivalent to 'KhJd, KdJh' - it is NOT the same as 'KhJd'. Similarly, in Omaha, if one wanted to specify a hand with ace-high flush potential in hearts single-suited, one would write 'Ahhxy' - it is NOT correct to write 'A:hhxy', as that would include hands such as 'AcJs7h6h'.

Card Order on Flop Game Boards

For games with a shared board (hold'em, omaha, omaha-8), the order of the first three cards (the 'flop') is not significant, while the order of the last two cards (the 'turn' and 'river') is significant. For instance, the boards 'KKJ' and 'JKK' are equivalent - they translate to 'a flop with two kings and one jack'. However, the boards 'sshds' and 'sshsd' are NOT equivalent - the first board has a flop with two spades and one heart, a diamond on the turn, and a spade on the river, while the second board has the same flop but a SPADE on the turn and a DIAMOND on the river.

Card Counts

For games where the number of cards in a hand is always known (hold'em always has 2 cards, omaha always 4), ranges are always implicitly 'topped off' with wildcards to bring the number of cards up to the correct number. For instance, in omaha, 'AA' is equivalent to 'AA**', and 'KJ:xxy' is equivalent to 'KJ**:xxy*'.

For stud games, card counts can vary. For stud and stud-8, card counts are brought up to a minimum of three cards, but no other topping-off is performed. For example, 'KJ' is equivalent to 'KJ*' (because all hands are brought to a minimum size of three). In addition, sub-ranges can only be combined if they have the same number of cards listed. For instance, 'KJ84:xxyz' is legal, whereas 'KJ84:xx' is not.

No Pair Constraint

You can enclose any number of cards in a subrange in curly braces to indicate that there are no paired cards. For instance:

A{A$W$W}- an omaha hand containg two aces and two non-paired wheel cards
{$W$W 5s}- a stud hand with a wheel draw headed by the five of spades

Special Stud Syntax

The pipe ' ' character can be used to delineate separate ranges for portions of a stud hand. For instance:

AA-TT, ss Ks-A big pair or two spades in the hole and a king of spades showing
xx:[9-Q][9-Q] RR s, K-Suited medium-large cards in the hole and a pair showing on fourth street followed by a spade or a king on fifth street

Note that each of the range pieces separated by ' ' are completely independent of each other. This means, for instance, that 'xx xx' does NOT mean four suited cards - it means two suited cards in the hole and two suited cards showing.

Syntax Macros

Syntax macros are a useful way to avoid typing in the same string of characters over and over again. Macros begin with a $ and may contain numbers and letters. Macros may reference other macros (but no macro may reference itself). The Generic Syntax comes with the following built-in macros:

Macro	Meaning	Games	Translates to	Example
$s	suited constraint	Hold'em	:xx	AK$s- ace-king suited
$o	off-suit constraint	Hold'em	:xy	JT$o- jack-ten off-suit
$B	big card	All	[A-J]	$B$B- two big cards
$M	middle card	All	[T-7]	$M$M- two middle cards
$Z	small card	All	[6-2]	$Z$Z- two small cards
$L	low card	All	[A,2,3,4,5,6,7,8]	$L$L$L$L!RRRR- four cards that can make a low (omaha hi/lo).
$N	no-low card	All	[K-9]	$N$N$N$N- four cards that cannot make a low (omaha hi/lo).
$F	face card	All	[K-J]	$F$F- two face cards
$R	broadway card	All	[A-T]	$R$R- two broadway cards
$W	wheel card	All	[A,2,3,4,5]	$W$W- two wheel cards
$ds	double-suited constraint	Omaha, Omaha Hi/Lo	:xxyy	AA$ds- double-suited aces
$ss	single-suited constraint	Omaha, Omaha Hi/Lo	:xxyz	AKQJ-9876$ss- single-suited medium-to-large rundown (hand has three suits)
$np	no pairs constraint	Omaha, Omaha Hi/Lo	!RR	15%$np- a hand in the top 15% with no paired cards
$op	one pair constraint	Omaha, Omaha Hi/Lo	:RRON	5%$op- a hand in the top 5% with exactly one pair (and no trips)
$tp	two pair constraint	Omaha, Omaha Hi/Lo	:RROO	20%tp- a hand in the top 20% with two pair
$nt	no trips constraint	Omaha, Omaha Hi/Lo	!RRR	50%$nt- a hand in the top 50% with no trips (or quads)
$0g	a zero-gap rundown	Omaha, Omaha Hi/Lo	AKQJ-	$0g:10%- a zero-gap rundown in the top 10% of hands
$1g	a one-gap rundown	Omaha, Omaha Hi/Lo	(AKQT-, AKJT-, AQJT-)	$1g:20%- a one-gap rundown in the top 20% of hands
$2g	a two-gap rundown	Omaha, Omaha Hi/Lo	(AKQ9-, AKT9-, AJT9-)	$2g:ss- a two-gap rundown with two or more spades

Weighted Ranges

Weighted ranges are supported for hold'em, omaha, and omaha hi/lo.

Weighted ranges allow you to specify the relative probabilities of hands appearing in a range. For instance, if we want a range where aces and kings are always played but queens are only played half the time, we could write 'AA-KK@100,QQ@50'.

Generic Syntax Odds and Ends

Case ('A' vs. 'a') is ignored. Nevertheless, ranges are easier to read if ranks and rank variables are capitalized while suit variables are in lower case.
Aces are always high. This means that 'A-5' is equivalent to '[A,K,Q,J,T,9,8,7,6,5]'. If you want wheel cards, you can use [A,2,3,4,5] instead.
Suits and suit variables are attached to the rank on their left. If the symbol immediately to the left is not a rank (A, K, ...), rank variable (R, O,...), or wildcard rank (*), then a wildcard rank is implicit. For example, 'ss' is equivalent to '*s*s', 'KsTsxx' is equivalent to 'KsTs*x*x', and 'sJhhd' is equivalent to '*sJh*h*d'.
Suit variables will not bind to any suits listed in a range. For instance, 'ssxx' means two spades and two cards of some other suit - the 'x' will not assume the value of spades. Similarly, rank variables will not bind to any ranks listed in a range. For instance, 'AARR' means aces with another pair - it does not include four aces.
Parentheses ('(' and ')') have the highest precedence, and can be used for grouping. For instance, '(AK, JT):xx' is equivalent to 'AxKx, JxTx'.
Constraints ('!' and ':') have the next highest precedence after parentheses, and are left-associative. For instance, 'AK,*:xx!RR' is equivalent to 'AK, (*:xx)!RR'
Commas (',') have the lowest precedence.

Key Differences vs. Classic Syntax

Here are a few quick notes for those of you who have made extensive use of the classic ProPokerTools range of hands syntax:

Hold'em Players

At long last, hold'em range syntax gets as much expressive power as omaha. Hooray!
's' and 'o' no longer mean suited and off-suit. 's' always means spades. If you want a suited hand, you have two options - you can use suit variables ('AxKx' for ace-king suited), or the suited macro ('AK$s'). For offsuit, use 'AxKy' or 'AK$o'.

Omaha Players

If less than four cards are specified, wildcards ('*') are added for you. Where you used to write 'AA**', you can now write 'AA'. Where a random hand was '****', '*' will now suffice.
'&' (the 'and' combinator) has been replaced with ':'. This is partly to avoid confusion with the old syntax, and partly because the colon just feels better.
Operator precedence has been fixed to match users' expectations. In the old syntax, errors seemed almost more common than correct usage when combining '&', ',' and '!'. Constraints ('!' ('NOT') and ':' ('AND')) now have high precedence and are left associative. This means that 'AK:15%, JT:30%, KQ!Ks' means what it looks like - namely, 'ace-king in the top 15% or jack-ten in the top 30% or king-queen without the king of spades'. The most common case where you need parentheses in the generic syntax is when you apply a constraint to a number of subranges, such as '(AA, AK):xxyy' for 'aces or ace-king double suited'.

Stud Players

Stud now has the same expressiveness as other games.
There is no longer a limitation that upcards be specific cards (although there is a maximum number of hands allowed in any range).
