Triangle Choke

A triangle choke, or sankaku-jime (三角絞) in Judo, is a type of figure-four chokehold which strangles the opponent by encircling the opponent's neck and one arm with the legs in a configuration similar to the shape of a triangle. The technique is a type of lateral vascular restraint that constricts the blood flow from the carotid arteries to the brain.

The triangle choke was seen in early Kosen judo competition. Tsunetane Oda, a judo groundwork specialist who died in 1955, had demonstrated the triangle choke on video. The move is often used in grappling and mixed martial arts. The front triangle is particularly favored by adepts of Brazilian Jiu-jitsu. More recently, several side or inverted triangles, typically seen more often in Judo competition, have been used in higher-profile MMA matches.
