Omaha poker
Omaha is comparable to hold’em because it also uses a three-card
flop on the board, a fourth board card, and then a fifth board card. Each
player is dealt four holecards (instead of two) at the start. In order
to make a hand, a player must use precisely two holecards with three boardcards.
The betting is the same as in hold'em. At the showdown, the entire four-card
hand should be shown to receive the pot. The best possible five card poker
hand, using exactly two hole cards and three community cards, wins the
pot.
