I am presently working my way through some of Yoda's old posts.
He stated-: "Per6-B-1-D, Extensor Action is always a below-plane Pull. This Pull straightens ideally, the entire Primary Lever Assembly (both the Left Arm and Clubshaft / 6-A-2) through Pressure Point #3. However, with the less skillful player, this #3 Pressure Point Pull may induce Clubhead Throwaway. In which case, the Extensor Action should be limited to astraightening of the Left Arm only (by Pulling on the Left Thumb through Pressure Point #1). In either event, the Extensor Action is always a Pulling Action, never a Pushing Action.
You can't Push a piece of string into a straight line."

I cannot understand this position. It is my understanding that the right hand is pushing on the left thumb (PP#1 point) in such a direction (directionally along the longitudinal axis of the left arm) so that it extends the left arm. The left arm is pulled straight, but it pulled straight by a
push-action exerted by the right arm/hand unit.
I also think that it is possible to push a string (which is lying on a tabletop) into a straight line - by using the tip of a finger to push against one end of the string (in a straight line direction towards a distant target point). This explanation is identical to the idea of a horse pushing against a harness in order to pull a cart in a straight line direction.
