Open Guard to Double Unders is the entry in which the top passer scoops both of the opponent’s legs onto their shoulders, elevates the hips, and clasps the hands behind the back to establish the bilateral-underhook stacking control.

Open Guard to Double Unders is the foundational entry into one of Brazilian Jiu-Jitsu’s most punishing pressure-passing controls, achieved when the top player digs both arms underneath the opponent’s thighs from an open-guard passing posture, lifts the hips off the mat, and clasps the hands behind the opponent’s lower back. Rather than passing immediately, this transition establishes the double-underhook stack as a stable controlling position from which side control, mount, or the back become available.

The entry shines against open guards where the legs are presented in front of the passer, particularly butterfly guard, seated/shin-to-shin guard, and supine open guards where the feet are not deeply pinning the hips. By committing both arms under the legs and driving the knees toward the opponent’s armpits, the passer stacks the defender onto their shoulders, eliminating frames and hip mobility before any passing motion begins. The defining requirement is timing: the underhooks must be dug as the opponent’s hips are momentarily light or as their guard opens, before they can re-pummel a foot or knee inside to create a frame.

For the passer this entry is a commitment. Diving both arms under the legs surrenders the ability to post, so it must be done with the head and chest already controlling the stack and the base wide. Done correctly it converts a neutral open-guard exchange into a dominant, fatiguing control. Done carelessly it exposes the passer to back-takes, hip-bump-style reversals, and deep half entries as the defender uses the passer’s committed posture against them.

Key Principles

  • Dig both underhooks simultaneously in one motion - a staggered, one-arm-at-a-time reach lets the opponent frame on the slow side

  • Drive the opponent’s knees toward their own shoulders to stack their weight before clasping, killing frames and hip mobility

  • Clasp the hands behind the lower back (gable or S-grip) or grip the belt so both legs become a single controlled unit

  • Keep your head pressuring into the chest or hip so the committed posture does not expose your back

  • Maintain a wide, mobile base on the toes so you can ride bridges and resist being rolled during the commitment

  • Time the entry to the moment the hips are light or the guard opens, never against deeply pinning feet

  • Treat the control, not the pass, as the goal of this entry - secure the stack first, advance second

Common Mistakes

  • Reaching under one leg at a time instead of digging both underhooks together

    • Consequence: The opponent frames or inserts a knee shield on the slow side, blocking the second underhook and stuffing the entry entirely
    • Correction: Treat the scoop as a single explosive motion driving both forearms under the thighs simultaneously so neither side is left exposed
  • Securing the underhooks only under the knees rather than the thighs

    • Consequence: The control is shallow, the opponent easily separates the legs, and the stack never consolidates
    • Correction: Drive your shoulders under their hamstrings so your forearms are deep beneath the thighs before you clasp
  • Clasping the hands before stacking the hips

    • Consequence: You lock a grip on an opponent who still has frames and mobility, allowing them to shrimp out or recover guard despite the grip
    • Correction: Elevate and stack the hips onto their shoulders first, then clasp the hands once their weight is already compromised

Playing as Defender

→ Full Defender Guide

Key Principles

  • Treat the moment the passer clears your feet as the alarm - the underhook entry is imminent and you have a narrow window to act

  • Keep a foot or knee framing on the hip or shoulder to deny clean penetration of both arms under your thighs

  • Make the entry asymmetric - if one underhook is in, frame hard on the open side to stop the second

  • Turn your hips to one side rather than accepting a flat stack, preserving a deep half entry on the low side

  • Exploit the passer’s committed arms - their back and balance are exposed, so dive under or bridge-and-roll when the stack forms

  • Use frames built on skeletal alignment, not muscle, so you survive the stack pressure without exhausting

Recognition Cues

  • The passer clears or strips your feet off their hips and steps their hips forward to close distance to your thighs

  • You feel one or both of the passer’s forearms sliding under your thighs and their shoulders dropping beneath your hamstrings

  • Your hips begin to elevate off the mat as the passer lifts with their shoulders and drives your knees toward your own shoulders

Defensive Options

  • Insert a knee shield or keep a foot framing on the passer’s hip to block the second underhook - When: The instant the passer clears your feet and reaches for the first underhook, before both arms are under your thighs

  • Dive underneath the passer’s committed posture to enter deep half guard - When: As the stack begins and the passer drives their weight forward but before the hands are clasped and the head is anchored

  • Bridge and roll into the passer’s committed arms to off-balance and reverse them - When: When both of the passer’s arms are buried under your legs and their base narrows or their head is not yet anchored

Variations

Belt/Waistband Grip Entry: Instead of clasping the hands behind the lower back, the passer grips the belt or waistband (gi) once both arms are under the thighs. This grip is harder to break than a hand clasp and gives a strong handle to steer the hips during the subsequent pass, at the cost of slightly slower entry speed. (When to use: Gi training where a belt or sturdy waistband is available and grip security is prioritized over entry speed)

Body-Lock Double Unders Entry: A no-gi adaptation where, after digging both underhooks, the passer connects the hands into a body lock meeting on the far hip rather than the lower back. This deepens the connection for no-gi where sweat makes grips slip and emphasizes a tighter chest-to-thigh stack. (When to use: No-gi or MMA contexts where grips are slippery and a deeper body-lock connection is more reliable than a behind-the-back clasp)

Position Integration

Open Guard to Double Unders is the bridge between neutral open-guard passing and the dedicated double-underhook pressure-passing system. It sits at the top of a passing tree whose branches include the Double Under Pass to side control, a back-take when the defender turns away, and a mount entry when the legs are cleared - all of which depend on first establishing the stacking control this entry provides. Within a passer’s game it complements other open-guard pass entries such as the toreando, knee cut, and leg weave, offering the heavy, committed option for opponents who present their legs in front rather than framing deeply on the hips. Strategically, mastering this entry teaches the passer to read when the hips are light enough to commit both arms and to consolidate control before advancing, a discipline that transfers across the entire pressure-passing hierarchy. For the guard player, understanding the entry from the defensive side is equally essential, since recognizing and interrupting it before the stack locks is one of the highest-value open-guard retention skills.
