Stack Pass

Quick Introduction​

The stack pass is a pressure-based guard pass that folds the opponent onto their own shoulders, taking their hips off the mat and neutralizing the legs from above. It is one of the oldest and most reliable passes in jiu-jitsu — Royce Gracie's UFC-era game relied heavily on stacking — and remains a go-to pressure pass at every level.

The technique works from closed guard, open guard, and butterfly guard with minor variations, and it pairs naturally with the over-under pass and smash pass.

Position Overview​

From: Closed Guard (opened), Open Guard, Butterfly Guard | Finish: Side control or knee-on-belly

The Standard Stack Pass​

  1. You're inside their guard (closed or open), postured up — head up, spine straight
  2. Hands control both their knees (or biceps, or pant cuffs) — both legs accounted for
  3. Drive forward into them, pushing their knees toward their own face
  4. Their hips lift off the mat as they get "stacked" — back rounded, knees by ears
  5. Pick a passing side — usually the side where they're weakest or least mobile
  6. Walk around toward that side, keeping pressure forward
  7. Slide your near hip down to the mat as you clear their legs over your head
  8. Land in side control, near-side underhook secured

Key detail: Posture is non-negotiable. Stacking with broken posture (head down, hands on the mat) folds you into a triangle or armbar.

Stacking From Closed Guard (Standing)​

  1. Open the guard by standing in their guard (knees on their hips, posture up, hands on their hips or belt)
  2. Force one knee through; their legs open
  3. Drop down and capture both legs (under-hook one thigh, control the other knee)
  4. Drive forward — stack starts
  5. Walk around to a side as above

Stacking From Open Guard​

  1. They're seated or on their back, you're standing or kneeling
  2. Step in close, posture up
  3. Hands grip both pant cuffs or both knees
  4. Drive your weight forward; their hips fold
  5. Choose a side, walk around, finish

Combining Stack + Over-Under​

  1. Set up the stack with both knees controlled
  2. Slide one arm under-hook around a thigh (the side you'll pass)
  3. Other arm over-hooks the other thigh, gripping their belt or pant
  4. Now you have over-under grip ON TOP of the stack
  5. Drive shoulder into their thigh, pin legs overhead, walk around

This combination — stack + over-under — is one of the most reliable pressure passes in BJJ at all levels.

Defending Common Counters​

Their counterResponse
They build hips up, push you backReset posture; don't lose your grip on knees
They invert/spinMaintain leg control on at least one leg; ride the spin
They frame on your bicepsStrip the frame, drive forward harder
They threaten triangleStep the threatened side out wide; pop posture immediately
They go to deep halfStop, reset; deep half neutralises the stack

Core Principles​

  1. Posture first, pass second — never stack with rounded back
  2. Both legs controlled — don't release one to grab grips elsewhere
  3. Forward drive, not arm push — pressure comes from hips and chest
  4. Pick a side decisively — late commitment lets the guard recover
  5. Slide the hip, don't jump — final entry is a smooth knee-to-floor transition

Common Mistakes​

MistakeFix
Broken posture mid-stackReset, posture up, then re-stack
Releasing one leg to "set up" the passMaintain both leg controls until you're clearing them overhead
Slow walk-aroundCommit to a side and move with intention
Stacking into a triangleCheck that both their arms are accounted for before driving forward

When to Look For It​

  • Opponent's hips are flat — easier to lift them onto shoulders
  • Smaller opponent or weight-class advantage — stack relies on top pressure
  • Gi or no-gi — works in both, grip details vary
  • Opponent has weak hips or limited flexibility — they can't bridge out
  • Less effective against tall/lanky players — they fold but recover guard quickly

Next Steps​

  1. Over-Under Pass — Natural combination with the stack
  2. Smash Pass — Pressure-pass cousin from half guard top
  3. Pressure Passing — Conceptual framework that includes the stack
  4. Knee-Cut — Stack's mobility-based counterpart for when stacking won't work
