Arm Triangle Choke — From High Knee-on-Belly
Variety肩固め（高膝乗せから）(Kata Gatame — From High Knee-on-Belly)
TraditionalTranslation: Shoulder Hold / Head-and-Arm Choke — From High Knee-on-Belly
Overview
A kata gatame (head-and-arm choke) variation performed from a high knee-on-belly position, where the attacker slides the knee further up toward the opponent’s chest or shoulder line. This elevated base increases shoulder and chest pressure into the opponent’s neck, creating a tight arm-triangle configuration while maintaining positional dominance.
History & Origin
Evolved from classical kata gatame; the “high knee ride” variation became common in modern BJJ as practitioners experimented with mobility and pressure attacks from knee-on-belly.
Effectiveness
High knee placement creates additional respiratory restriction that compounds the choking pressure, making the arm triangle finish faster and more difficult to defend. [1]
Lineage
The arm triangle from high knee-on-belly combines the pressure of KOB with the head-and-arm strangle, developed in modern BJJ. [1]
Competition Record
This transition is seen at advanced BJJ competition levels where positional control leads to submission opportunities. [1]
