PLO button opening hands

What should you open on the button in PLO?

The button is the widest first-in seat, but it is not a license to open anything with an ace in it. Good button opens still need connection, suit coverage, and a real route to the nuts. This guide gives you a practical baseline you can use before you reach for the opening-range tools.

Open Premium rundowns, strong Broadway shapes, and hands that keep more than one nut path alive.
Mix Pair-plus-support, suited aces with real structure, and deeper-stack hands that still connect.
Fold Disconnected rainbow hands, weak gap hands, and holdings that only look playable because of one card.

Button baseline

Open the hands that keep real nut pressure alive.

On the button, the safest default is still structure. Start with premium rundowns, strong Broadway shapes, and pair-plus-support hands that can make the nuts or keep redraws live. As the table softens or stacks deepen, widen into more connected suits and hybrid shapes, not into random high-card combinations.

Open

Premium rundowns and double-suited Broadway hands.

  • A♠ K♠ Q♦ J♦ keeps straight and flush routes open.
  • K♠ Q♠ J♥ T♥ stays live across a wide range of flops.
  • Q♠ J♠ T♥ 9♥ still plays like a system instead of a guess.
  • These are the hands you can open most comfortably without needing table softness to rescue them.

Mix

Hands that need depth, softness, or both to be worth more often.

  • A♥ A♣ K♠ Q♠ gains value when the side cards keep the hand live.
  • A♠ J♠ T♦ 8♦ wants more room to realize equity.
  • K♥ Q♥ 9♠ 7♠ can be fine when position and table texture help.
  • Mixing is about context, not about pretending a marginal shape is premium.

Avoid

Hands that look playable but do not keep enough nut routes alive.

  • A♠ Q♦ 8♣ 3♥ is too disconnected for a clean button open.
  • K♥ J♣ 8♦ 2♠ lacks the engine that makes PLO hands valuable.
  • Any hand that only feels good because it has one high card usually belongs lower in the range.
  • The button is wide, but it is not a reason to open trash.

Example opens

Use concrete hand shapes instead of guessing from rank alone.

These examples are the fastest way to turn the idea into a preflop habit. Read the shape first, then ask whether the hand keeps enough connection, suit density, and redraw value to justify the open from the button.

Clear open

A♠ K♠ Q♦ J♦

Open. This is the cleanest kind of button hand because it keeps broadway pressure, suit leverage, and straight potential all at once.

Clear open

K♠ Q♠ J♥ T♥

Open. Two suits and a clean run make this a strong candidate when you want to attack from the widest seat.

Mix

A♥ A♣ K♠ Q♠

Mix. The pair matters, but the side cards have to keep the hand connected enough for the open to stay clean.

Mix

A♠ J♠ T♦ 8♦

Mix. Stronger with depth, later-game pressure, or softer blinds that let the hand realize more of its equity.

Usually fold

A♠ Q♦ 8♣ 3♥

Fold. A lone ace is not enough when the rest of the hand is disconnected and vulnerable to domination.

Usually fold

K♥ J♣ 8♦ 2♠

Fold. The gaps are too wide and the hand does not keep enough useful boards in play against real resistance.

Depth and table texture

The button widens first, but depth and softness still change the answer.

Deeper stacks reward hands that keep redraws live because later streets matter more. Shorter stacks tighten the cutoff because speculative gaps become harder to realize. Live loose tables can widen the button a little, but the hand still has to be coherent enough to continue when called.

100BB

Keep the opening pool centered on hands with clean nut routes.

  • Open the strongest connected shapes first.
  • Mix only when the hand is still structurally sound.
  • Do not widen just because the seat is good.

150BB+

More hands play when redraws can realize across later streets.

  • Suited aces with support move up.
  • Pair-plus-connectivity hands gain value.
  • Deep stacks reward hidden nut potential more than thin made hands.

Live cash

Soft tables let the button widen a little, not a lot.

  • Dead money and limps can justify a wider attack.
  • Bad structure still plays badly when the pot grows.
  • Use table softness as a tiebreaker, not as a substitute for shape.

Common mistakes

The biggest button leak is opening too wide for the wrong reason.

Being on the button makes weak hands look less dangerous than they are. The fix is simple: open for structure, not for optimism.

Mistake 1

Opening every hand with an ace.

A bare ace does not save a disconnected hand. If the rest of the cards do not help, the hand still belongs below the open threshold.

Mistake 2

Using the same button range at every stack depth.

Hands that are fine deep can become much less attractive at 100BB when the postflop room disappears.

Mistake 3

Ignoring how the blinds defend.

If the table is active and the blinds continue well, the button range still needs stronger structure to hold up after the flop.

Mistake 4

Confusing cheap opens with profitable opens.

A hand that is cheap to enter is not automatically a hand that realizes enough equity to be worth the pot.

FAQ

Short answers for the most common button-opening questions.

Is the button the widest open seat in PLO?

Yes. It is usually the widest first-in seat, but the hand still needs connectivity, suit coverage, and a real route to the nuts.

Should I open every suited ace on the button?

No. Suits help, but disconnected hands still fail when the structure does not support them.

What hands are safest to open on the button?

Premium rundowns, strong Broadway shapes, and pair-plus-support hands are the safest starting point.

How does stack depth change the answer?

Deeper stacks reward redraws and hidden nut potential, while shorter stacks push you back toward cleaner, more direct strength.

What should I read next?

Use the opening-ranges guide, then compare one hand across seats with the checker and the evaluator.

Does this replace a chart?

No. It gives you a usable baseline. The opening-range tools turn that baseline into seat-by-seat confirmation.

The cleanest study loop is simple: read the button baseline, test the same hand in another seat, and confirm the result against the broader opening-ranges guide. That keeps the site free, useful, and practical.
