Most clinches in wrestling come naturally. Head and arm, Over Under, and Under Hooks are pretty easy to get by accident.
The Russian 2 on 1, however, is not something you stumble upon by accident. Untrained people generally have no idea what it is and how to deal with it, so it gives you that south paw edge if you learn it well.
One of the first techniques every wrestler learns from the 2 on 1 is the throw by. It is simple, effective, and easy to setup – my favorite type of move.
