Application of ACCs-2-3

[Amen Corner]

I started a similar thread on the topic of PA#3 release in the advanced section.

Okie - Regarding the magic of PA#3's roll action, you wonder what makes the left hand roll into impact.

I suspect that the major factor is the movement of the right palm. At the delivery position. the right elbow is still bent at a right angle and the right palm faces more-or-less in the direction of the ball-target line. Then, during the release swivel phase of the downswing, the right elbow straightens and that causes the right forearm to paddlewheel into impact so that the right forearm is behind the shaft at impact and the right palm faces the target at impact. That means that the right palm moves through a 90 degree rotation during the release swivel phase of the swing, and that phenomenon should roll the left hand over (= release of PA #3). On page 73 of the 7th edition, HK states-: "The "On plane" Right Forearm ALWAYS establishes and maintains the correct clubshaft-left arm angle through release and impact".

Jeff.

The straightening of the rear arm is of great importance, imo, when talking about the relationship between acc 2 and 3.

As you stated above, being on plane to begin with. But let´s not forget about which loading the player is intending to use and thereby where the rear elbow is positioned.

This would affect if the release is sequenced or simultanious.
