Difficulty:

Guard Attacks

Triangle Choke (Sankaku-Jime)

IBJJF: White+

Submission (Instant Win)

One of the highest-percentage submissions in grappling history. Traps the opponent’s head and one arm between your legs to compress both carotid arteries.

Biomechanical Execution Steps

1Control opponent wrists or sleeve grips; push one arm inside your guard while pulling the other outside (1-In, 1-Out principle).
2Shoot your hips up explosively and lock your ankles behind the opponent’s neck.
3Cut a 45-degree angle to the trapped arm side, grab your own shin with opposite hand to secure the frame.
4Place your foot on the opponent’s hip to angle out further, lock the figure-four (knee over foot), squeeze knees together, and bridge slightly.

Common Execution Mistakes

•Staying flat and straight in front of opponent instead of cutting the angle
•Failing to pull the trapped arm across the opponent’s centerline
•Grabbing your own foot instead of your shin (risking self-ankle injury)

Opponent Defense & Counters

•Posture straight up with hands framed on opponent hips
•Stack pass: drive knees into opponent chest and walk hips around to side control

Apparel Tip: Ranked rashguards with silicone hem prevent slippery sweat from breaking your shin lock grip.
