[Yoda]

Here's an interesting point which is not in the book. So please look away for those who's only into pure Homer Kelly.

The Golfing Machine says that the Left Wrist controls the Clubface. But once you've mastered the idea of producing different Hinge Actions with your Left Wrist remaining Vertical to one of the three Basic Planes, a very convenient way to control the Clubface is through the Lag Pressure sensed by Pressure Point #3. 'What?' you may ask, 'I thought Pressure Point #3 was only for sensing Clubhead Lag Pressure'.

[Bold by Yoda.]

Convenient, yes, but not as precise.

Convenient because control of both the Clubhead and Clubface are now in one Hand.

Imprecise because variations in Right Elbow Bend and Location will disturb the Clubface alignments, making it an inferior procedure.

Better to free the Right Hand and Arm of all responsibility except their Straight Line Drive through the Ball and Plane Line Tracing. And assign to the Left Wrist the task of returning to Flat and Vertical at Impact for execution of the Hinge Action.

Left Hand -- Hinge Action and Clubface Control.

Right Hand -- Clubhead Lag Pressure and Clubhead Control.

Unless, of course, you prefer to do it otherwise. In which case, Homer Kelley would have been the first to say...

"Fly at it!"
