Обзор
A head-and-arm choke (kata gatame) applied from knee-on-belly. The attacker pins the opponent with the knee ride, isolates the near arm across the opponent’s neck, and drives the shoulder and chest into the carotid while locking a head-and-arm clamp. Finish is created by shoulder adduction, chest pressure, and angle change—not by leg triangling.
История и происхождение
Modern BJJ adaptation of kata gatame that emphasizes using the mobile knee-on-belly pin to create the arm-across feed and immediate finishing pressure.

Биомеханический механизм
Action — Lateral vascular compression using opponent’s trapped arm against their neck plus attacker’s shoulder/chest pressure
Joints Affected — Neck (carotid arteries), shoulder of the trapped arm
Torque/Force — Shoulder adduction with scapular protraction; chest drop; head positioning to close space; base stabilized by knee-on-belly
Позиция и вход
From side control, post to **knee-on-belly** (knee centered, toes active). With your **right hand** cross-face across the jawline to turn the head away; your left hand controls the near wrist/triceps and **feeds the arm across** the opponent’s neck. Slide your **right arm under the head** and around the opponent’s neck/arm, connect palms (gable) or RNC-style (grab right biceps, left hand to crown). Keep knee pressure to pin hips, **drop right shoulder** toward the neck, **walk your body toward the head at ~45°**, and sprawl the left leg for base. Squeeze elbows, drive chest, and micro-adjust head position to close the space for the choke. Optionally transition to mount while maintaining the lock if you need more pressure.

Заметки по тренировке
✓Maintain knee ride pressure to stop hip shrimping
✓Keep the opponent’s elbow **high and across**—if it slips below the chin, reset the feed
✓Finish by **angling** (walk toward the head and drop shoulder), not just squeezing arms
✓If space remains, transition to mount or switch to d’arce/anaconda as the arm slips.
Типичные ошибки
!Trying to finish without the arm truly across the neck
!Leaning too far forward and getting rolled
!Keeping head too high (leaves space)
!Squeezing without walking angle/shoulder drop (becomes neck crank instead of choke).

Часто задаваемые вопросы
What should I do if my opponent pushes my knee off during knee-on-belly?
Let them push your knee off and turn into you—this is actually what you want. According to ROYDEAN, when they turn into you, you can grab the collar ridge, circle your forearm around to create a wall, and finish the choke by rolling your bottom wrist up into the neck.
How do I set up the grip correctly for the arm isolation triangle from knee-on-belly?
ROYDEAN recommends opening the collar, grabbing the ridged material, and starting your forearm at about the middle of the opponent's head. Then circle your forearm around tightly so the top arm becomes a wall, with your bottom wrist ready to roll up into the neck.
What if I'm too short to finish the choke with my pinky in the crook of my elbow?
ROYDEAN suggests modifying the grip for bigger opponents or if you're shorter: instead of pinky-to-elbow, simply place your hand flat on your forearm and roll it up the same way as you compress.
How do I finish if my opponent has an underhook and his arm is stuck in front of him?
ROYDEAN recommends threatening an armlock by straightening your arm on the ground to push against their elbow, forcing them to turn. Once they turn in, dive your shoulder below their lat to enter the triangle position and finish the choke.
