If you walk into a five-card PLO tournament with four-card instincts, three things will cost you chips before the first break: you will overvalue pretty hands, underweight redraws, and pay off too many second-best made hands.

The fifth card does not just make your hand stronger. It makes more players connect harder, with more backup, in more directions — and tournament chip preservation does not forgive that.

If you are still building the baseline adjustment from four-card to five-card, start with the broader PLO5 strategy transition guide, then come back here for the tournament stack-depth rules.

What Changes Immediately

Three shifts hit on day one:

  • Nuttedness thresholds rise. A flopped straight that was a comfortable get-in hand at four-card is now a frequent second-best.
  • Redraws get heavier. Made hands more often arrive with flush, boat, or higher-straight backup that improves through the river.
  • Hand-class separation compresses. The gap between "good" and "stack-off good" is narrower; the penalty for confusing them is wider.

The tournament-specific consequence: pots go multiway more often, opening fields play looser early, and a dominated stack-off near a pay jump is the single most expensive mistake you can make.

The Decision Lens, Stated Once

Before any chip decision, ask:

  1. Nut path — does this hand make the nuts on the streets that matter?
  2. Redraw density — when it makes a strong hand, does it keep improving?
  3. Domination risk — how often does it make an expensive second-best holding?

That is the entire framework. Use it as a filter, not a chapter.

Five-Card Tournament Strategy by Stack Depth

This is the section that earns its keep.

100bb+ (Levels 1–4 of most events)

Realization is good and mistakes are recoverable, but the stack lets opponents punish bad postflop construction over multiple streets.

  • Open more: double-suited connected aces (A♠K♠T♥9♥8♦), high-quality middling rundowns (J♠T♠9♦8♦6♣), pair-plus-rundown hybrids with two suits.
  • Open less: pair-with-danglers (A♣K♦K♠Q♥4♣), unsupported high-card broadway (A♥Q♥J♣9♦4♠), gappy rundowns missing a suit.
  • 3-bet only: double-suited AAxx with a connected side card and double-suited connected aces. Skip 3-bets with rainbow AAxx and high-card hands; flat or fold.
  • Flat OOP: single-suited rundowns with no gap, and double-suited connected aces. Fold disconnected high-card and weak single-suited broadway from the blinds.
  • Stack-off threshold: top set without nut-flush coverage, a straight blocker, or a paired board is a one-street hand on coordinated boards.

40–80bb (the awkward band)

SPR drops fast, so one flop decision often commits the stack. Postflop realization is poor — defend less, attack tighter ranges.

  • Open the same nut-path hands as 100bb+, but cut middling rundowns from UTG and UTG+1.
  • Flat OOP: essentially never. Either 3-bet or fold.
  • 3-bet selectively at 50–70bb: restrict 3-bets to hands you would commit at 4-bet — double-suited AAxx with side connectivity, and double-suited connected aces. Everything else, flat IP or fold.
  • BTN versus single raise: defend any clean rundown 8-high or higher, double-suited or pair-plus-rundown. Fold pair-with-danglers entirely.
  • Stack-off rule: with a non-nut made hand, you need at least two of {nut-flush draw, nut-straight redraw, top-set or better, paired board}. One redraw is not enough at this depth.

Sub-30bb (commit-or-fold territory)

Stop thinking "see a flop." Start thinking "what is my stack-off range, and what is my pay-jump exposure?" The same patterns covered in beating short-stacked PLO apply, with one extra wrinkle: in a tournament you cannot reload.

  • Open from EP: AAxx with any rundown component, KKxx double-suited, and rundowns 9-high or higher with a suit. Fold middling rundowns and pair-with-danglers.
  • 3-bet/jam thresholds at 20–25bb: jam AAxx single- or double-suited, KKxx double-suited, and double-suited connected aces. Fold rundowns to opens — they realize too poorly when shoved over.
  • Defend BB versus single raise: any rundown with a suit, AAxx, KKxx, and double-suited connected broadway. Fold rainbow high-card hands even at price.
  • Reshove range over an open with 12–18bb: tighter than four-card. Aces and double-suited rundown wraps only.
  • Pay-jump rule: with 25–35bb in the money, preserving a dominated stack-off is worth more than the 5–8% equity you would pick up by gambling. If your hand has only one redraw, fold and reload your strategy at the next pay jump.

Preflop Hand-Class Quick Reference

Five classes, two actions each, no hedging.

Premium connected aces — A♠K♠T♥9♥8♦

  • 60bb CO open: yes; 3-bet over a BTN re-raise.
  • 25bb UTG: open. Multiple nut paths and redraw density survive low SPR.

Pair with danglers — A♣K♦K♠Q♥4♣

  • 60bb UTG: fold.
  • 25bb BB versus BTN open: fold. The dangler poisons multiway value.

Middling rundown — J♠T♠9♦8♦6♣

  • 60bb BTN versus CO open: call.
  • 30bb UTG: fold; the suit does not survive a re-raise that puts you all-in.

Weak single-suited broadway — A♥Q♥J♣9♦4♠

  • 60bb CO: fold.
  • 60bb BTN versus single raise: defend only headsup against a wide blind opener; multiway, fold.

Four-card-looking trap — K♠K♥J♣7♦3♣

  • 60bb UTG: fold.
  • 25bb BB versus BTN open: fold. The fifth card adds nothing — no connectivity, no nut path, just a dominated KK in a multiway pot.

Tag every hand from these classes you played in your last session as looked premium, dominated multiway. Review the tag the night before the event.

Postflop Example: Naked Straight vs. Redraw-Rich Straight

CO opens 2.5bb at 55bb effective. BTN calls. BB calls. Pot 7.5bb. Flop J♠9♦7♣ (SPR ~7).

  • BB: K♣T♣8♦4♠3♥ — straight, no clean redraw.
  • BTN: A♠T♠8♥6♥5♦ — straight, plus open-ended toward the nut, plus backdoor nut-flush, plus key blockers.

CO checks.

  • BB action: check. Leading is a chip-burn — ahead of CO's range now, behind by the river versus half of it. This is a check-call hand, not a check-raise hand.
  • BTN action: bet 60% pot. With clean future coverage, build the pot while CO and BB have to respect every turn card.
  • If BB check-raises BTN: BTN calls. Do not 3-bet — you fold out worse and bloat against sets and higher straights.
  • Turn 2♣, BB leads pot: BTN folds. The hand cannot improve cleanly into a three-way 1.5x-pot turn raise.

The principle: at 55bb with one street already played, your made hand needs an upgrade path. Without one, you are a bluff-catcher with no fold equity. Confirm the redraws math yourself in the PLO5 equity calculator before you trust this in-game.

Second Postflop Example: Four-Card Continue, Five-Card Fold

UTG opens, BTN calls, BB calls. 60bb effective. Pot 8bb. Flop K♥7♥4♣ (SPR ~7).

BB: A♠Q♥J♥T♦5♣ — second-nut flush draw, gutshot to broadway, two overcards.

In four-card PLO, this is a routine check-call versus UTG's c-bet. In five-card PLO with three players, fold the check-call. UTG's continuing range now contains a King with a heart redraw, the nut flush draw with overcards, two-pair-plus-flush-draw, and sets with a redraw. Your second-nut flush is dominated by half the heart cards UTG can have, and BTN's call narrows you further.

Correction rule: when you are drawing to a hand that is frequently second-best in the five-card field, demand price (≤25% pot facing one bet) and zero multiway exposure, or fold. The same logic applies to most non-nut flushes at this depth.

Three Tournament-Killing Mistakes

Top set on a coordinated board, no backup. A♠A♦J♣J♥4♠ on J♦T♠8♣, three-way at 40bb. Correction: check-call once, then re-evaluate. Stack off only with nut-flush blockers or a paired turn.

Non-nut flush in a multiway pot. Q♥J♥T♣9♠3♦ on K♥8♥4♣2♥, three-way. Correction: check-call max one street, fold to a raise. Never lead the river.

Weak wrap at 30–40bb. Q♠J♦9♣8♣4♥ on T♥7♠2♦. The wrap hits a non-nut straight half the time. Correction: call one bet, fold to action. Save 35bb for a cleaner spot at the next pay jump.

A One-Week Five-Card Tournament Prep Routine

  • Day 1–2: 15–20 preflop spots split 5/5/5 across 100bb+, 40–80bb, sub-30bb. Write one concrete action per hand: open, call, 3-bet, fold.
  • Day 3–4: 10 postflop stack-off spots. Note seat, player count, effective stack, SPR, and a one-line action plan.
  • Day 5: review last session for the three mistake tags above. No other leak hunting — you are sharpening, not rebuilding.
  • Day 6: five bubble or pay-jump hands. Include at least one 35bb preservation example where the right play is fold and reload.
  • Day 7: one rep through the equity calculator on your three closest stack-off decisions from Day 3–4.

Bring one card to the table:

  • What nuts do I make here?
  • If I am strong now, what improves cleanly?
  • If this goes multiway, am I value-betting or walking into domination?

Answer those three before any chip decision over 25% of your stack and the four-card instincts stop costing you chips.
