"the point may be made that is impossible to inscribe perfect circles while center is in motion. that is the turning shoulder. the straight line requirements of the compression point are satisfied as long as both horizonal and vertical centers move precisely in unison. directional control remain stable because both centers are moving precisely in a circle....THAT IS THE CIRCUMFERECE OF THE SHOULDER TURN." there are anatomical considerations for the shoulders to turn in a cirlcle as you know. my first question to you is how do you rectify turning the shoulders turn in a circle and transfer the weight on the backswing? translating only the hips would tilt the spine to the left....translating the hips and the head would violate the circle requirements. next, how do you reconcile the change of standard knee action from edition 2 to right anchor in later additions?? as it seems to me the right anchor flattens the hips and shoulder turn? the flatter than rotated shoulder turn change the horizonal component of the backswing and translate the axis of the shoulder turn back to the right....violating 2g(later 2h)......of course all bets are off if you allow the hip and shoulder turn to both move back equally (lunge equals sway). all the best Thanks for your post, Andy. Good questions all and ones I will be happy to discuss in detail later. Meanwhile, I am stealing time from Mrs. Yoda waiting with my cold coffee on the terrace at Baltusrol as I post this quick answer from the locker room. 1. The Shoulder turns about its Pivot Center, the Stationary Head (or, alternatively, the 'point between the shoulders'). The Pivot Center remains fixed, regardless of other Component Motion or Action, e.g., the Weight Shift via the Hip Slide (in either direction or both). 2. With Head held Stationary, any Weight Shift (Hip Shift) does indeed cause the lower spine to swing away from its fixed top. Again, this 'tilt' occurs in both directions. The movement of the lower spine toward the target in the Downstroke is well known. The movement away from it in the Backstroke has been virtually ignored. 3. Both items #1 and #2 above are possible because of our 'Hula Hula flexibility' -- the ability to move the Shoulders independently of the Hips (and vice versa) -- as described in 7-12 (the Pivot). 4. The Bent Knee (either the Right on the Backstroke or the Left on the Downstroke) does indeed flatten the Hip Turn. Any straightening of either Knee tilts the Hips in the direction on the straightened knee. This straightening is the 'Standard Action,' so described by Homer Kelley because "this is the way it has been done [by most golfers] for centuries." The Maximum Participation Stroke Pattern in the 3rd edition utilized this Standard variation (10-16-A) because it has the most movement of the Knee Action Variations, i.e., the "Maximum Participation." 5. In his personal work with students, Homer Kelley himself differentiated between the Sample Stroke Patterns of the 3rd edition -- customized Patterns -- and the Basic Stroke Patterns of the later editions (12-1-0 and 12-2-0). This is a great topic. Let's keep it going. Meanwhile, Andy, I'm off for Westchester and the Barclays Classic this afternoon. Hope to see you on the tee! __________________ Yoda Yoda View Public Profile Send a private message to Yoda Visit Yoda's homepage! Find all posts by Yoda
