Omaha is often played high-low split, 8-or-better. The
player may use any combination of two holecards and three
boardcards for the high hand and another (or the same)
combination of two holecards and three boardcards for
the low hand.
The rules governing kill pots are listed in “Section
13 – Kill Pots.”
RULES OF OMAHA HIGH-LOW
1. All the rules of Omaha apply to Omaha high-low split
except as below.
2. A qualifier of 8-or-better for low is used. This
means to win the low half of the pot, a player's hand
at the showdown must have five cards of different ranks
that are an eight or lower in rank. (An ace is the highest
card and also the lowest card.) If there is no qualifying
hand for low, the best high hand wins the whole pot.
