Overhook Extraction is a critical defensive technique for escaping the New York position within 10th Planet’s Rubber Guard system. When trapped in New York Top, your arm is locked in a deep overhook while your opponent’s shin crosses your back, breaking your posture and compromising your base. The overhook extraction addresses the arm control component, freeing your trapped limb and opening pathways to posture recovery and guard passing.
The technique operates on the principle that the overhook, while strong, has a structural weakness: it requires constant tension and positioning from the bottom player. By systematically changing the angle of your trapped elbow and using rotational movement rather than linear pulling, you exploit the overhook’s blind spots. The key insight is that pulling straight back reinforces the overhook, while corkscrewing your elbow downward and toward your hip creates an angle the overhook cannot maintain.
Strategically, overhook extraction should not be attempted in isolation. The sequence must address base and posture concerns simultaneously. Attempting extraction without stable base invites sweeps; attempting it without addressing posture allows the bottom player to transition to other attacks like triangles or omoplatas. When executed correctly within the proper sequence, overhook extraction serves as the gateway from defensive survival in New York to offensive guard passing opportunities.

Key Attacking Principles
- Never pull the trapped arm straight back - this reinforces the overhook and triggers counter-attacks
- Corkscrew motion (elbow down and toward hip) exploits the overhook’s structural blind spot
- Base establishment must precede extraction attempts - wide knees prevent sweeps during the technique
- Posture engagement during extraction prevents triangle transitions as the arm comes free
- Grip fighting the opponent’s shin-controlling hand creates space for the extraction motion
- Speed is secondary to angle - correct elbow angle succeeds where explosive pulling fails
- Immediate guard passing engagement after extraction prevents opponent from re-establishing control
Prerequisites
- Wide base established with knees spread to prevent sweeps during extraction attempt
- Free hand actively grip-fighting opponent’s shin-controlling grip or framing on their hip
- Core engaged and weight distributed to resist forward pressure from opponent
- Mental recognition that overhook grip has weakened or opponent’s attention is divided
Execution Steps
- Establish base: Widen your knees significantly to create a stable triangular base. Your free hand should frame on opponent’s hip or grip-fight their shin-controlling hand. Without stable base, the extraction will result in a sweep.
- Engage posture: Begin driving your chest upward while keeping your trapped elbow tight to your body. Do not attempt to stand or create distance yet - focus on engaging your posterior chain to resist the downward pull of the shin control.
- Compromise shin control: Use your free hand to grip-fight opponent’s hand that is controlling their own shin. Peel fingers or strip the grip by pushing their wrist toward their body. Even partially weakening this grip reduces the structural integrity of the entire New York position.
- Angle the elbow: Rotate your trapped elbow downward so it points toward your own hip rather than toward the floor. This subtle angle change is critical - it positions your arm for extraction rather than reinforcing the overhook’s grip.
- Corkscrew extraction: While maintaining the downward elbow angle, begin a spiraling motion toward your hip. Think of unscrewing a tight lid rather than pulling straight back. Your elbow leads the motion, your shoulder follows, and the arm extracts in a curved path.
- Maintain posture through extraction: As your arm begins to free, immediately drive your posture upward. The moment of extraction is when triangle attacks become available - keeping your head and shoulder high prevents the leg from shooting over your shoulder.
- Secure passing grips: The instant your arm is free, establish control on opponent’s legs or hips for guard passing. Do not pause to celebrate the extraction - your opponent will immediately attempt to re-establish New York or transition to other guards.
Possible Outcomes

| Counter | Triangle Control | 10% |
Opponent Counters
- Opponent deepens overhook and tightens shoulder-to-armpit pressure when they feel extraction beginning (Effectiveness: High) - Your Response: Pause the extraction and focus on grip-fighting their shin control instead. Once shin control is compromised, return to the extraction sequence. → Leads to New York
- Opponent shoots leg over your shoulder for triangle as your arm extracts (Effectiveness: High) - Your Response: Drive posture up and stack immediately. The triangle attempt requires your head down - keeping posture defeats the counter and may create passing opportunities. → Leads to Triangle Control
- Opponent uses your extraction motion to generate hip bump sweep momentum (Effectiveness: Medium) - Your Response: Maintain wide base throughout and keep weight centered over both knees. If sweep begins, post with free hand and drive weight toward the sweep direction to counter. → Leads to New York
- Opponent transitions to Invisible Collar or Zombie before extraction completes (Effectiveness: Medium) - Your Response: Recognize early and shift to stack defense rather than continuing extraction. Address the new position before returning to overhook extraction attempts. → Leads to New York
Test Your Knowledge
Q1: What is the primary goal of Overhook Extraction and what comes immediately after? A: The primary goal is to free your trapped arm from the opponent’s deep overhook control in New York position. However, the extraction itself is not the end goal - it is the gateway that enables offensive action. The instant your arm is free, you must immediately establish grips on opponent’s legs or hips and begin guard passing before they can re-establish rubber guard control.
Q2: Why does pulling straight backward fail against a properly set overhook? A: Pulling straight back reinforces the overhook’s biomechanical advantage. The overhook is designed to resist linear pulling force - the opponent’s shoulder-to-armpit pressure creates a wedge that tightens under direct resistance. The solution is angular extraction using a corkscrew motion that exploits the overhook’s blind spot below and behind the grip.
Q3: What base position must you establish before attempting overhook extraction and why? A: You must establish a wide base with knees spread significantly before attempting extraction. Without stable base, the focus required for extraction leaves you vulnerable to sweeps - the bottom player can use hip bump or other sweep mechanics while your attention is on the arm. Wide base creates a stable platform that can absorb sweep attempts during the extraction sequence.
Q4: Your opponent shoots their leg over your shoulder as your arm extracts - what went wrong and how do you respond? A: Your posture dropped during the extraction, creating the opening for triangle. The response is immediate stacking - drive your head and shoulder up and forward while pushing into your opponent’s hips. This removes the space needed for the triangle to lock. The correction for future attempts is maintaining upward posture throughout extraction, not just at the end.
Q5: Describe the correct elbow angle and motion path for the corkscrew extraction technique? A: The elbow should angle downward toward your own hip rather than pointing at the floor or flaring outward. From this angle, execute a spiraling motion as if unscrewing a tight lid - the elbow leads, drawing a curved path toward your hip while the shoulder follows. This spiral exploits the overhook’s structural weakness at angles below and behind the grip line.
Q6: Your opponent deepens their overhook when they feel your extraction beginning - how do you adapt? A: Pause the extraction attempt and redirect your effort to grip-fighting their shin-controlling hand instead. The shin control and overhook work together as a system - compromising the shin control reduces the structural integrity of the entire New York position. Once their shin control weakens, return to the overhook extraction with improved odds of success.
Q7: What is the optimal timing window for initiating the corkscrew extraction? A: The optimal window occurs when your opponent’s attention shifts away from maintaining overhook tension - typically when they are adjusting their shin grip, attempting to transition to a deeper rubber guard position like Invisible Collar or Zombie, or when they pause momentarily after a failed attack attempt. Initiating during these windows of divided attention significantly increases extraction success rate.
Q8: What grip must you address on your opponent before the extraction has highest chance of success? A: The shin-controlling grip is the priority target. Your opponent’s hand gripping their own shin creates the closed kinetic chain that powers the entire New York position. Stripping or weakening this grip before attempting extraction reduces the structural integrity of the overhook simultaneously, because the shin control provides the leverage that keeps your posture broken and your arm trapped.
Q9: How does the direction of force differ between the corkscrew extraction and a standard arm pull? A: A standard arm pull applies force directly backward along the arm’s axis, which the overhook is mechanically optimized to resist. The corkscrew extraction applies force in a downward spiral toward your own hip - a rotational vector that the overhook cannot efficiently counter. The force path curves below and behind the opponent’s shoulder-to-armpit wedge, bypassing the overhook’s strongest resistance plane entirely.
Q10: Your extraction attempt is blocked and your opponent begins transitioning to Zombie - what is your response? A: Immediately abandon the extraction and shift to stack defense. The Zombie position deepens leg control and creates additional choking threats that are more dangerous than New York. Address the transition by driving your weight forward into your opponent’s hips to prevent their leg from climbing higher. Once you have neutralized the Zombie attempt and returned to New York, reassess whether extraction or an alternative escape is more viable.
Safety Considerations
Overhook extraction carries moderate injury risk primarily to the shoulder and elbow of the trapped arm. Never explosively yank your arm to escape - this can hyperextend the elbow against the overhook pressure or strain the shoulder capsule. The corkscrew motion should be smooth and controlled. If you feel significant pain during extraction, stop and work to create space rather than forcing through. Partners should release immediately if the person on top signals discomfort. When drilling, start with zero resistance and progress slowly to ensure both partners understand the mechanics before adding intensity.
