The game is broken down into five distinct phases:
Pre-flop: Players are dealt four cards each that only they can see. Then there is the initial betting round and much like Texas Hold'em, there is a Big Blind and Small Blind.
The Flop: The dealer places the first three community cards face up on the board. Then the second round of betting will take place.
The Turn: The dealer places one more community card face up on the board. Another round of betting happens.
The River: The last betting round. The dealer places the fifth and final community card face up on the board.
Showdown: The players still in the hand reveal their cards to determine the winner.
Once at the showdown, remaining players reveal their cards. This is where a critical rule for Omaha comes into play:
You must use exactly two cards from your four-card hand and exactly three cards from the five community cards on the board to make your best five-card poker hand.
This is a key difference from Texas Hold'em, where you can use one, two, or even none of your own cards. In Omaha, you cannot "play the board".
Many new players make the mistake of using only one of their four hole cards. Let's look at an example to see why this is a costly error.
Imagine you have A♥ Q♣ 7♦ 6♦ in your hand.
The community cards are 10♥ 5♥ 9♣ 2♥ K♥.
You might think you have a flush because you have an ace of hearts and there are four hearts on the board.
This is incorrect!
The rules of Omaha require you to use two of your hole cards. You cannot make a hand using only one hole card (your A♥) and four community cards. In this scenario, your best hand is actually just a pair of queens (using the Q♣ from your hand and the Q♥ from the board), as you cannot form a flush with only one heart in your hand.
This is the most common mistake beginners make, so remember: two cards from your hand, three from the board!
While the basic rules of poker remain constant, the betting structure profoundly changes a game. No-Limit and Pot-Limit are the two most common betting formats, each with its own unique strategic nuances. Understanding these differences is key to mastering each game.
Minimum Bet: A bet must be at least the size of the big blind, and any raise must be at least equal to the previous bet or raise.
Common Game: No-Limit Texas Hold'em is the most popular poker variant in the world.
Betting: The maximum bet or raise is equal to the total amount of chips currently in the pot.
Calculating a Pot-Limit Bet: The maximum raise is the sum of the current pot plus the amount you need to call to stay in the hand. For example, if the pot is 100 Chips and a player has bet 20 Chips, the total pot is now 120 Chips. You would need to call the 20 Chips, so you can raise by the full pot, which would be 120 Chips. Your total bet would be 20 Chips (the call) + 120 Chips (the raise) for a total of 140 Chips.
Strategy: This format leads to more post-flop action because it's difficult to go all-in pre-flop. Players can't just shove all their chips in at the beginning of the hand; they must build the pot step-by-step, leading to more turns and rivers being seen.
