Five-Card PLO: More Cards, More Complexity

Unless you've been away from poker for a few years, you've probably run into PLO5 games — live or online. The format is gaining popularity fast, and many players are asking the same question: is it actually worth learning?

While PLO5 is still less common on major online platforms, it has quickly become a favorite in live games, especially among action-oriented players. Many PLO cash tables now include the five-card variant, and in some cases, it even replaces traditional PLO.

The reason is simple: with five cards, the game becomes even more dynamic, leading to bigger pots, closer equities, and more action overall.

So, what exactly changes in PLO5 — and how should you adjust your strategy?

How Is PLO5 Different From PLO?

At first glance, the only difference between PLO5 and PLO is the number of hole cards. That's mostly true — but this one extra card changes the flow of the game more than you might expect.

Let’s start with the number of preflop combinations — the additional card increases it dramatically.

Start with the math. The extra card increases the number of preflop combinations dramatically:

• No-Limit Hold'em: 1,326 combinations
• PLO4: over 270,000 combinations
• PLO5: roughly 2.8 million combinations

PLO4 and PLO5 share the same pot-limit rules and the same community cards, so the differences come down to the details of hand selection. The fifth card adds complexity — and that makes correct preflop play even more important.

You already know how easy it is to get carried away in regular PLO: many hands simply look good to less experienced players. This effect is even stronger in PLO5. With five cards, every hand contains at least two cards of the same suit, and most hands have some level of connectivity.

Don't be fooled by this. On average, a playable PLO5 hand needs to be a stronger version of a playable PLO4 hand — not a looser one.

For example, in mid-stakes Pot Limit Omaha at 100 BB, you can profitably open UTG with nearly 64% of your KK combinations. In PLO5, under the same conditions, that number drops to around 30%.

There are many more nuances like this — such as a stricter approach to double-suited hands in some spots, a more flexible approach to cold calling in some scenarios, or less aggressive play with certain AA combinations. These adjustments, among others, form the foundation of a solid PLO5 strategy.

While overall opening frequencies by position may look similar to regular PLO, the real edge comes from these finer details.

Common Mistakes in Five-Card PLO

As in PLO4, Aces in PLO5 are not always hands you want to raise or reraise preflop.

This effect is even more pronounced, as equities run closer in PLO5. As a result, it’s rare to get all the chips in preflop with a meaningful equity edge. That said, premium AA hands still perform well — for example, AAJJT double-suited can have around a 60/40 edge over weaker AA holdings like AA2T7 single-suited.

Correct preflop decisions carry over into postflop play, too. With deeper stacks, the edge from good hand selection matters even more.

Postflop Discipline Is Everything

In No-Limit Hold'em, flopping top pair is often strong enough to commit a large part of your stack — sometimes all of it. In regular PLO, that's already far less common: only top pairs with strong side cards can be played aggressively or hold up under pressure.

In PLO5, top pairs are even more vulnerable. Most of the time, only the strongest combinations with well-connected side cards can continue when facing aggression.

PLO5 rewards discipline more than almost any other format. You'll often need to fold hands that look strong but perform poorly in practice, simply because their equity is too low.

A good example is stacking off with “the nuts.” For less experienced players, getting all the chips in with the best made hand may seem natural.

In PLO5, this can be a costly mistake. For instance, holding 8♠7♠ on a 6♦5♣4♥ board without any backup (no redraws) against the same straight combined with a set or a flush draw can leave you with less than 30% equity — despite currently holding the best hand.

This is the key idea: in PLO5, you need to think beyond your current hand strength and consider how your hand performs on future streets.

Where the Edge Comes From

The good news: PLO5's nature attracts action-oriented players who are reluctant to fold hands like a bottom or middle set, or a weak flush.

With so many possible preflop combinations, it's easy to misjudge which hands are actually worth playing in the first place. Many players today understand Texas Hold'em preflop strategy reasonably well — but PLO5 preflop strategy is far less studied and far less intuitive.

As a result, PLO5 often has some of the softest fields among mainstream poker formats. If you don't believe it, try a local cash game — you might be surprised.

Why PLO5 Is Worth Playing

PLO5 is a complex format, but that complexity is exactly where the opportunity lies. Many players underestimate how much the fifth card changes hand strength and decision-making, which leads to frequent mistakes. With a solid grasp of the fundamentals, you can exploit these gaps and build a real, lasting edge.
