Arm triangle pin
Also known as Kata Gatame — the canonical term used on this site.
Training background: Describing the pin-and-choke dual function
Descriptive — pin-and-choke dual function
Arm triangle pin is the descriptive name for the kata gatame — flagging the pin’s structural identity as the holding-configuration of the arm-triangle choke, with the same geometry serving both pin and submission roles.
Etymology. “Arm triangle” specifies the structural form; “pin” attaches the positional-hold category (distinct from “choke” which would attach the submission category). The compound predominates in coaching contexts that emphasise the pin-and-choke dual function explicitly.
Mechanics. The same closed-loop arm-and-chest structure that produces the arm-triangle strangle also pins the bottom player — the configuration is “always already” the submission setup, which is the position’s psychological leverage.
Cross-reference. “Head-and-arm hold” is the alternate name; kata gatame is the Japanese name. Full mechanical coverage on Kata Gatame.
