A variation of poker where the pot in each game is split between the best and the worst hands. The worst hand usually comprises the five lowest cards, so in Omaha hi/lo on VC Poker, the nut low is A, 2, 3, 4, 5.
In Hi/Lo games, the pot is split with half going to the best high hand, and half to the best low hand. Many hi/lo games have a qualifier for low which means hands must be at least 8-low to be in contention for the low half of the pot.
