Mir Lock Escape
Mir lock escape — the one arm attack the tucked elbow does not answer. Deny the overhook, strip it before the clasp closes, then follow the rotation.

The Mir lock takes an overhook above your elbow, folds your bent arm across the attacker’s chest, clasps it there, and turns it up and away until your shoulder runs out of rotation. For the attack, see Mir Lock. You will meet it wherever you present a near arm — under K-guard, Z-guard or the clamp, and from underneath knee on belly, north-south or side control. It shares that position set with the shotgun armbar, and the two read the same offered arm.
★ This is the arm attack your arm defence does not answer. The corpus is consistent about keeping the elbow bent and connected to the ribs — it denies the armbar, the straight armlock and the baratoplata. The Mir lock attacks a bent arm at roughly a right angle. Folding your elbow does not deny it; folding your elbow is the shape it wants.
What denies it is winning the arm battle above the elbow. An overhook is the whole control, and an arm that never gets reached over is an arm this cannot touch. That makes the defence a hand-fighting habit rather than a submission escape, and it sits in the same family as the bicep slicer, where the trained reflex is also what finishes you.
Elevated RiskMir Lock (defending) is an elevated risk technique. Two joints loaded together. The shoulder takes rotation through the capsule and rotator cuff; the elbow, folded and turned rather than extended, takes a torsional load. Compound loading shortens the tap window, and rotational shoulder pressure gives its warning late — the shoulder has genuine rotational range, so the movement feels survivable well past the point where the capsule is loaded. Sources are consistent that held past the tap it damages both joints. Serious injury can occur fast — two joints together, with the shoulder's rotational signal arriving later than an elbow extension would.
