And another question..........did he arch it for iron shots only?

Its a horizontal hand motion, but the opposite to the usual one, a reverse bend to the left wrist. A little bit of "insurance" against Throwaway and a closing clubface. Given a weak left hand grip you need to arch it to get the hands ahead at impact. You dont need to "turn it down" if you have a neutral to strong left hand grip.

Is the Arch a "compensation" then? Hmmm


D, are you saying you cant roll continuously and Horizontal Hinge? You saying the arch is a little hold off move to a roll? It could be.

Yes, the Arch is a little hold off move to a roll. It results naturally from his swivel and allows him to Horizontal Hinge.

The Left Wrist must remain Vertical to the associated Horizontal Plane through Impact to achieve a Closing Only alignment through the Impact. Rolling through Impact would Impart a Hooding motion through Impact and would work well if you set up to strike the ball at low-point because it would additionally supply the downward blow to sustain the line of compression. However, in a normal procedure, the Clubhead is moving Down and Out and is responsible for those two elements of a three dimensional Impact. Horizontal Hinging is responsible to turn the Line of Compression during the three dimensional Impact, to sustain the line of compression through the Impact until separation. The Hookface design of the Clubhead diverts the Ball from a Circular path to a Straight Path.
