A Stud game where the best high hand and the best 8-or-lower low split the pot.
A low is 5 unpaired cards of 8 or lower, and if there is no low, the high takes the whole pot. You choose freely from 7 cards, so you can use different 5-card hands for high and low (an ace also counts as 1). Example: (A-2) 5 gets a 49% share against KK (56% if all 3 are the same suit), and a high-only K-Q-J gets 44% against a 3-card low. The E in HORSE.
