### Triangle Choke: Korobi Jime The Triangle Choke, or "Korobi Jime" in Japanese, is a quintessential Brazilian Jiu-Jitsu submission technique leveraging an opponent's arm and shoulder to constrict the blood flow to the brain, resulting in a choke. It primarily utilizes the legs, making it a popular and powerful option from guard positions. --- ### Positions - **Closed Guard** - **Open Guard** - **Half Guard** - **Rubber Guard** --- ### Step-by-Step Technique – From Closed Guard 1. **Control the Posture** - Begin in the closed guard with your legs locked around your opponent's waist. - Control your opponent's posture by pulling their head down with one hand while subtly securing one of their wrists with your opposite hand. 2. **Create an Angle** - Use your same-side hand on the controlled wrist to push the opponent's arm across your body. Their arm should reach from your chest to your opposite shoulder. - Simultaneously, use your legs to maintain a tight grip, ensuring their posture doesn't rise. 3. **Secure the Triangle Position** - Swiftly unlock your closed guard and position one leg across your opponent's upper back, ensuring your knee aligns close around their neck. - The opposite leg should move over the shoulder and close on their upper back into a figure-four position. - **Tip:** Hip elevating will create space and make it easier to slip the leg through for securing the triangle. 4. **Lock and Adjust** - Latch the ankle of the first leg behind the knee of the second leg. - Your first leg's foot should point towards the direction of their head, ensuring tight pressure. - Make any necessary adjustments by pulling on your shin of the first leg (not the foot), ensuring your calf compresses against their neck. 5. **Constrict the Choke** - Pull their head down gently as you lift your hips off the ground. - Maintain this pressure while squeezing your legs together, intensifying the choke. - **Tip:** If needed, shift the angle by rotating your position sideways or shrimping slightly away from your opponent to increase choke effectiveness. 6. **Finish the Choke** - Use continued leg pressure and control over their head until your opponent taps. --- ### Important Safety Tip Always apply submissions gradually, especially chokes. Be aware of your partner's verbal and physical taps to prevent injury. ### Practice and Development The Triangle Choke is about angle control and positioning. Consistent practice helps in refining leg dexterity, arm movement, and opponent control, broadening your offensive arsenal in Brazilian Jiu-Jitsu.
