Omaha
This list covers all 56 hands that qualify in an 8h split pot game.
Omaha H/L, 7 Card Stud H/L, as well as being the best 56 hands in A5 Triple Draw
Outs and Odds Against are your best tool in Omaha because of the nature of the game and your starting hand selection. In some cases you will have several outs to win the pot when your starting hand allows you for multiple possible cards to finish your straight draw (for example you hold 4 5 6 7 and the board is 9 8 2 3 any remaining 5 will give you a 9 high straight, A will give you a 5 high straight, 10 will give you a 10 high straight leaving you with 11 possible outs.)
Key Differences Between Hold Em and Omaha: Omaha has 4 down cards instead of the 2 in Texas. You MUST use 2 down cards in combination with 3 Table Cards to win in Omaha.
The following applies to Omaha only, not Omaha High / Low. In Omaha High / Low you want hands that will win both the high and the low such as AK23 double suited or something similar. Think A2345 and TJQKA put together.
