Standing leg lock defence

Standing leg lock defence is a descriptive name for standing vs entangled guard — framing the standing position as the defence to a leg entanglement.

Etymology. “Standing” names the posture; “leg lock defence” frames it by purpose, staying upright to avoid the finish. The label names the position by what it protects against rather than the entanglement it faces.

Mechanics. Staying standing denies heel exposure, which is determined by position rather than grip: from a vertical posture the attacker keeps the threatened heel hidden and the knee aligned, so the entanglement cannot rotate to the angle a finish requires.

Cross-reference. “Stacking defence against ashi,” “Vertical ashi defence,” and “Standing 50/50 counter” are sibling aliases. Full mechanical coverage on Standing vs Entangled Guard.
