Maybe it is a vertical hinge making contact prior to layback? But what makes it fly so far? Simple trapping?

I was not using the correct TGM terms to describe a very effective technique. Thanks to Darly, Jerry, OB Left, and Kevin for the insights.

The left wrist (front wrist) vertically cocks or is neutral, or uncocks before swiveling right or left with the aid of the forearm. Try it!

Now watch this video! Let's start with Lynn Blake's very simple video you can watch here:

If you swing or hit, you are cocking the left wrist and uncocking it by pulling the power package to discharge and fully swivel the left wrist to the left ear or by driving the front arm or primary lever. I use this stroke everywhere except within 150 yards and in.

If you start with a fully uncocked front wrist and pull or drive that wrist, you get a "chicken wing" if you don't folow through.
If you do follow through, you get a nice high finish.

The right forearm supports the primary lever and drives it in swing or hit. The support of the right forearm and the flatness of the uncocked left wrist is normally only experienced when both arms are straight. My guess is that the uncocked left wrist has fewer moving parts when driven through impact and therefore less power loss. More effective power transfer, and more consistent club head motion maintains accelleration. The de-lofting of the club adds distance as well. Yesterday, my short irons and chips were all 10 yards longer than normal.

Enjoy your game!
