SAFETY: Triangle Choke Side targets the Carotid arteries and jugular veins. Risk: Carotid artery compression causing unconsciousness. Release immediately upon tap.
The Triangle Choke Side (also called Side Triangle or Kata Gatame Triangle) is an advanced variation of the traditional triangle choke executed from top positions, most commonly from side control or north-south transitions. Unlike the standard triangle from guard where the defender is between the attacker’s legs, the side triangle traps one of the opponent’s arms across their own neck while the attacker’s legs create the choking mechanism from a perpendicular angle.
This submission represents a sophisticated understanding of triangle mechanics, as it requires precise leg positioning and body angle adjustments that differ significantly from the bottom triangle. The side triangle often emerges opportunistically when opponents defend traditional side control attacks by creating frames or attempting to turn into the attacker. The choke’s effectiveness comes from the ability to isolate one arm while using it as a wedge against the opponent’s own carotid artery.
The side triangle is particularly valuable in no-gi grappling and MMA contexts where traditional collar chokes are unavailable, and it serves as an excellent counter to common defensive reactions from bottom positions. Mastery of this technique demonstrates advanced technical knowledge and the ability to recognize and capitalize on dynamic positional transitions.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Carotid artery compression causing unconsciousness | CRITICAL | Immediate with proper release; potential for concussion if unconscious |
| Neck strain from torque and pressure | Medium | 3-7 days with rest |
| Shoulder hyperextension from trapped arm | Medium | 1-2 weeks with proper care |
| Jaw compression and TMJ stress | Low | 2-5 days |
Application Speed: EXTREMELY SLOW - 5-7 seconds minimum application time in training. Blood chokes can cause unconsciousness in 3-8 seconds under competition pressure.
Tap Signals:
- Verbal tap (any vocal signal)
- Physical hand tap on partner or mat
- Physical foot tap on mat
- Any distress signal or change in breathing pattern
- Loss of resistance or body tension
Release Protocol:
- Immediately release leg pressure and open triangle configuration
- Remove all pressure from neck and trapped arm
- Allow opponent to turn head to restore blood flow
- Check partner’s consciousness and breathing immediately
- If unconscious: elevate legs, monitor airway, ensure medical attention if needed
- Never apply additional pressure after tap signal
- Maintain awareness of partner’s neck angle throughout release
Training Restrictions:
- Never spike or jerk the submission - always apply gradual, controlled pressure
- Never use competition-speed application in training scenarios
- Always ensure partner has at least one hand free to tap
- Never practice on partners with pre-existing neck, jaw, or shoulder injuries without explicit clearance
- White belts should only practice with supervision and on willing, experienced partners
- Stop immediately at any sign of partner distress beyond normal defensive reactions

Playing as Attacker
Key Principles
-
Angle perpendicular to opponent’s body - side triangle requires 90-degree body positioning relative to opponent’s torso, not the parallel alignment of traditional triangles
-
Trap one arm across opponent’s neck - the isolated arm must cross their own centerline to create the choking wedge against their carotid artery
-
Figure-four leg configuration - same locking mechanism as traditional triangle with one leg across the back of neck and the other locked behind the knee
-
Hip pressure toward opponent’s head - driving hips toward their head tightens the triangle and prevents them from posturing or creating space
-
Control the free arm - the opponent’s non-trapped arm must be controlled or pinned to prevent defensive hand-fighting and escape attempts
-
Adjust angle dynamically - as opponent defends, continually adjust your body angle to maintain perpendicular pressure and prevent them from turning into or away from the choke
-
Squeeze knees together, not just legs - the finishing pressure comes from bringing knees toward each other while maintaining the lock, creating circumferential compression

Common Mistakes
-
Applying triangle from parallel position instead of perpendicular angle
- Consequence: Choke fails because pressure is distributed incorrectly, and opponent can easily posture or turn to escape. Parallel positioning mimics bottom triangle mechanics which don’t work from top positions.
- Correction: Always ensure your body is 90 degrees to opponent’s torso with hips high and positioned toward their head. Think of making a ‘T’ shape with your bodies. Reposition before attempting to finish if angle is wrong.
-
Locking triangle before properly securing trapped arm position
- Consequence: Opponent pulls their arm out during the lock transition, eliminating the choking mechanism entirely. Triangle without the trapped arm is ineffective and easily escaped.
- Correction: Use upper body pressure and grips to fully secure the arm across their neck before committing to the leg swing. Patience in the setup phase is critical - don’t rush to lock the triangle.
-
Failing to control opponent’s free arm during finish
- Consequence: Opponent inserts free hand into triangle, creates space, or uses it to frame and escape. Free arm gives them multiple defensive options that compromise the submission.
- Correction: Dedicate one or both hands to controlling the free arm throughout the finishing sequence - grab wrist, pin to mat, or hug to your body. Never leave their free hand uncontrolled during the finish.
Playing as Defender
Key Principles
-
Arm position awareness - never allow your arm to cross your own centerline toward your neck while under side control, as this creates the primary choking mechanism for the attacker
-
Early intervention priority - the best defense occurs before the triangle locks; once the figure-four is established, escape difficulty increases exponentially with each second
-
Create space inside the triangle - if locked, immediately work to insert your free hand between your neck and the attacker’s thigh to relieve carotid compression and buy time
-
Address the perpendicular angle - turn your body toward or away from the attacker to disrupt their 90-degree alignment, which weakens the choking pressure significantly
-
Protect the free arm at all costs - your free hand is your primary escape tool; if both arms are controlled, escape options become extremely limited and submission is imminent
-
Stay calm under pressure - blood chokes create urgency but panic burns oxygen faster; controlled breathing and systematic escape attempts are more effective than explosive scrambling
Recognition Cues
-
Attacker begins controlling your near-side wrist or forearm and guiding it across your own neck while maintaining side control pressure on your upper body
-
Attacker shifts their hips upward toward your head and begins lifting their near-side leg off the mat, indicating they are preparing to swing it over your head and neck
-
You feel your own arm being wedged against your neck with increasing shoulder pressure, and the attacker’s chest weight shifts from your torso toward your head
-
Attacker’s leg crosses over the back of your neck and their shin settles across your cervical spine while they reach for their own ankle or knee to establish the figure-four lock
Escape Paths
-
Arm retraction to side control bottom: Pull trapped arm back past centerline before triangle locks, using elbow retraction and shoulder rotation to clear the arm from the choking position
-
Free hand insertion and head extraction: Insert free hand as a wedge into the triangle space, create separation between neck and thigh, then systematically work head out of the opening by turning and ducking
-
Bridge and angle disruption to guard recovery: Explosive bridge toward attacker to break perpendicular alignment, then turn into them and work legs between bodies to recover half guard or closed guard
