What is a half nelson?

A half nelson is a wrestling move in which one participant reaches behind the opponent's neck with one arm and locks their own hands together in order to gain control and potentially manipulate the opponent's body into a disadvantageous position. This move is commonly used to control or pin an opponent in wrestling matches. The half nelson is often combined with other wrestling techniques to create effective combinations and submissions. Mastering the half nelson requires strength, technique, and precision in order to execute it successfully.
