Opposite-side triangle escape
Also known as Opposite Triangle Escape — the canonical term used on this site.
Descriptive — triangle closed on the far side
Opposite-side triangle escape is the descriptive name for opposite triangle defence, where the lock closes on the side away from the trapped arm rather than across it.
Etymology. “Opposite-side” specifies which shoulder ends up inside relative to which leg crosses. It is a fussy distinction on paper and a decisive one in practice, because it changes the direction the defender must turn to relieve the strangle.
Mechanics. Turning the wrong way tightens the lock, so identifying the closing side precedes any escape attempt. Once identified, the defence follows the standard triangle hierarchy — recover the arm, rebuild posture, turn toward the closed side — with the direction reversed from the front triangle a defender is used to.
Cross-reference. “Far-arm triangle defence” is the alternate name. Full escape coverage on Opposite Triangle Escape.
