In Omaha Hi / Lo, a “high” hand is defined in the same way as in Hold'em or Omaha, following the traditional hand rankings. The “low” hand requires a little more explanation, especially if you are new to split play or high-low poker. First of all, whatever cards you use to make your hand, it doesn't matter for a low hand. You can use the same two cards, two other cards, or any combination, as long as you use two cards from your four-card hand plus three community cards to create a five-card hand.
