The half nelson is referred to by most coaches as being the easiest but most effective move in folkstyle wrestling, and is very commonly used.
The half nelson is done using only one hand, by passing it under the arm of the opponent and locking the hand on the opponent's neck.
Several different nelson holds exist, and they can be separated according to the positioning of the encircling arm(s). A nelson is used to control an opponent or to turn them over onto their back and execute a pin.
HOW TO
You’ll start by getting your opponent "broken down" (flattened to belly) laying face down with you on top.
First reach across to the opposite side from you placing your far hand under your opponents armpit and securing their wrist.
Next you will pass your near hand under the arm of the opponent and locking the hand on the opponent's neck.
When the half nelson is applied first suck the far wrist (wrist control) toward your opponents chest then get up and drive the shoulder the half nelson is on toward your opponents ear.
As you opponent roles over sink the half in deeper and settle back so you are chest to chest with the opponent.
Once the opponent is on their back make sure to pick up the head and squeeze, look up and be on your toes with a wide base.
