[1] There are two common methods for playing high-low split games, called declaration and cards speak.
Especially when using the ace-to-five low method, it is possible for one player to have both the low hand and the high hand, and therefore win all of the pot (called "scooping," "hogging" the pot, or "going pig").
In the event more than one player ties for either high or low, the pot can be further split into quarters or smaller fractions.
It is common, especially in cards speak games, to require a certain hand value or better to win the low half of the pot, called a qualifier.
The sets may overlap: for example, in seven-card stud played high-low split, a player dealt 7-7-6-4-4-3-2 can play a high hand of 7-7-4-4-6 (two pair, sevens and fours) and a low hand of 7-6-4-3-2 (seven-high).
