Welcome to 5-card Pot-Limit Omaha (PLO). The first thing to understand is that it's a completely different game from No-Limit Hold'em, especially before the flop. In Hold'em, a hand like pocket Aces is a massive favorite against a random hand. In 5-card PLO, the equities run much closer together. This means the best starting hand is only a small favorite against a mediocre one.

With five cards, the number of possible combinations skyrockets. This leads to bigger, more complex hands postflop. Your preflop goal is to play hands that work well together and give you multiple ways to hit a strong hand like a straight, a flush, or a full house. Let's look at a quick comparison.

Notice the difference? Even a premium hand like double-suited Aces and Kings in PLO is only a 60/40 favorite against a connected, but much weaker, hand. This is the single most important concept to grasp. Because equities run so close, you'll see more players entering the pot, making postflop skills and, crucially, position, paramount.

Since you have five cards, you want them all to coordinate. A good starting hand has a combination of three key features: high cards, suitedness, and connectivity.

The best hands combine all three elements. Consider a hand like A♠️ K♠️ Q♦️ J♦️ T♣️. This hand is amazing. It has high cards (A, K, Q, J, T), it's double-suited (spades and diamonds), and it's perfectly connected. It can make the nut straight, the nut flush, and a variety of other strong hands.

Conversely, a hand like K♠️ 8♦️ 7♣️ 3❤️ 2❤️ is very weak. It has one high card, but the rest of the cards are disconnected and don't work together. It has a weak flush draw and minimal straight possibilities. This is a hand you should fold without a second thought.

If close equities are the most important mathematical concept in PLO, position is the most important strategic one. Position refers to the order in which players act during a betting round. Acting last is a massive advantage.

When you're in late position (like the Cutoff or the Button), you get to see what everyone else does before you have to act. This gives you more information. Did they raise? Did they just call? How many players are in the hand? This information allows you to make better decisions.

Because you have this informational edge, you can play a wider range of hands profitably from late position. From early position, you're acting with less information, so you must be much more selective. You should only play your strongest, most coordinated hands from up front.

A hand that might be an easy fold in early position could become a profitable hand to play in late position, especially if several players have already entered the pot. Your goal is to play strong, coordinated hands in position against weaker ranges.

Time to test your understanding of these preflop fundamentals.

Mastering these preflop principles is the first step. By selecting hands that are coordinated and playing them from the right position, you set yourself up for success on later streets.
