Over The Chin Finish

Variety

顎越しフィニッシュ(Ago-Goshi Finisshu)

Transliteration

Translation: over the chin finish

Overview

The Over The Chin Finish is a rear naked choke variation where the choking arm is applied over the opponent's chin rather than under it — using the forearm to push the chin upward and backward while the bicep and opponent's shoulder create bilateral compression on the neck. ^[1] While technically a crank element, the over-the-chin RNC is legal in most competition formats and is used when the opponent's chin tuck prevents standard under-chin placement. ^[1],[2]

Biomechanical Mechanism

Primary Action — Applying this specific choking or cranking configuration to the opponent's neck or spine

Joints Involved — Neck (cervical spine — the target of all chokes/cranks in this family), arms (the choking limb creates the compression surface), shoulders (positioning determines the choking angle)

Force Vector — Bilateral compression (chokes compress from two sides) or rotational/extension (cranks apply torsion or hyperextension)

Submission Mechanic — The specific grip, arm positioning, and body alignment create the unique compression geometry of this variation

Position & Entry

From back control — Establish back control, then transition to this specific choke/crank variation

From front headlock — Secure the front headlock, then apply this specific choke configuration

From the parent position — Enter through the position described in the parent genus/species

Variants

Training Notes

✓Apply slowly in training — chokes and cranks can cause injury if applied explosively

✓Tap early when caught — blood chokes cause unconsciousness rapidly; neck cranks can damage the cervical spine

✓Drill the specific grip and positioning until automatic

✓Chain with alternative choke variations when this one is defended

Common Mistakes

!Applying too fast — gradual application is safer and often more effective

!Wrong grip positioning — the specific grip variation defines this technique; incorrect grip = different technique

!Not controlling posture before applying

!Holding after the tap — release immediately
