Omaha Hi/Lo
The rules of Omaha are very similar to those of Texas Hold'em.
Each player receives four hole cards, instead of two.
A player must use exactly three community cards and two hole cards to make one's hand.
Aces are either low or high, and straights and flushes don't count
for low.
Since everybody must use two hole cards to make a hand, the board
must have three cards 8 or lower for a low to even be possible.
Players often tie for low, and the low half of the pot is divided equally among them.
