Less than full shots.
On these less than full shots, the real ememy is SLACK.
THE MANZELLA DICTIONARY
SLACK:
How much you can turn your hips toward the target while your shoulders stay still. Also, how far you can move your arm/hands/club unit (the Power Package) without moving your shoulders.
The answer is a Delayed Pivot with a Delayed Hip Action.
In DELAYED "Hip Action," the Shoulders pull the hips around on the backswing and the Hips pull the shoulders on the downswing. By configuring the "Open-ness" of the stance, how much weight is on the left foot, and how much you use the knees to stop the Shoulder Turn, you can precisely make what FEELS LIKE a FULL BACKSWING and a "normal" downswing, and hit it a precise distance.
The DELAYED Pivot is simply this "restricted" backswing pivot and a "normal" downswing pivot.
Then, all you have to do is control SPEED, SHAFT LEAN, and COMPRESSION and you'll be as good as anyone with the wedges.
