Syntax for board structure

The syntax described below can be used to specify text-based input in the "Board" section of the postflop editor.




Values
AKJ: Only AKJ boards are accepted.
AK*: The board is AKx, where x is any card.
(AK**): The board is AKxx. The board contains no pairs in the part within the brackets. If it's (AA**) then AA is not counted as a pair.
AK>7: The board is AKx, where x is a 7 or higher.
AK<7: The board is AKx, where x is a 7 or lower.
AK[8,Q]: The board is AKx, where x is 8 through Q.


Flush properties
AK5f0: The board is AK5 rainbow.
AK5f2: The board is AK5 with a 2 flush.
AK5f3: The board is AK5 with a 3 flush.
AK5f>2: The board is AK5 with at least a 2 flush.
AK5f<2: The board is AK5 with at most a 2 flush.


Overcards to the flop or board
On the turn, an overcard can be specified as [>B] or [>F], for instance ***[>B].
On the river, an overcard to the flop is [>F] and an overcard to the board is [>B].

For example, ***[>F][>F] means that both the turn and river are overcards to the flop, however, the river may be below the turn card. So 239KJ would be TRUE here.


Cards relative to the flop or board
It's also possible to specify a turn/river to be relative to other flop/board cards.
For example, ****[>2F] means that the river will be greater than the second flop card (but below the top flop card).

Other examples:
- ****[>=3B]: River is above or equal to 3rd board card (but below 2nd card)
- ****[>=3F]: River is above or equal to 3rd flop card (but below 2nd card)
- ***[<2F]: Turn is below second flop card (but above third flop card)
- ***[=2F]: Turn is equal to second flop card
- ***[<=2F]: Turn is at most second flop card (and above the third flop card)
- ***[>2F][<2B]: Turn is above second flop card and river is below second board card
- ***[>B],***[<3B]: The turn is either an overcard to the board or below the third board card


Defining multiple boards
Multiple boards can be separated by a comma: AK*,AQ*,AJ*.


Combining value/flush/overcard properties
Any combinations of the above are possible.
