Mounted Triangle Escape

This page covers escape from the mounted triangle — a triangle choke applied from mount, with the attacker above and one leg across the defender’s neck locked behind the other leg’s knee, and the defender’s arm trapped inside. Bilateral carotid compression comes from the inner thigh on one side and the defender’s own trapped shoulder on the other. Because the attacker is on top, gravity adds weight to the compression and the defender cannot use posture-up escapes available against the guard triangle.

For the attack, see: /technique/triangle/mounted-triangle. The mounted triangle arrives via S-mount (most commonly) or high mount when the defender elevates a shoulder to defend an armbar. The position is structurally hostile to escape — the defender is on bottom, the attacker has gravity, and the triangle has already locked. Escape priority is upstream: prevent S-mount arm isolation, block the leg before it crosses the neck, and disrupt the lock before it tightens.

Mounted sankaku jime escape(Japanese — triangle choke from mount)

The mounted triangle has a clear staged assembly from mount. Each stage compounds the difficulty of the next.

Early stage — Mount with arm isolation (S-mount forming)

The attacker is transitioning to S-mount and isolating one of the defender’s arms across the body. The triangle has not yet formed. This is the cleanest escape window — standard mount escapes (elbow escape, upa bridge, heel drag) still apply, and preventing the arm isolation prevents the triangle entirely.

Committed stage — Leg crossing the neck, triangle forming
