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 β 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 β Applying this specific choking or cranking configuration to the opponent's neck or spine
Joints Involved β Neck (cervical spine β 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 β Bilateral compression (chokes compress from two sides) or rotational/extension (cranks apply torsion or hyperextension)
Submission Mechanic β The specific grip, arm positioning, and body alignment create the unique compression geometry of this variation
Position & Entry

From front headlock β Secure the front headlock, then apply this specific choke configuration
From the parent position β Enter through the position described in the parent genus/species
