[O.B.Left]

Couple of ideas for your consideration.

-the pull might not be directly related to the head pull in. For pull correction research or hit the search function for the following key words: "roundhousing", "startdown waggles", "Turned Shoulder Plane, TSP", "Hip Slide with a Delayed Turn", "Cleared right hip".

-The head pull in thing. By adjusting your body around the RFFW at Impact Fix you will, amongst other things, establish the exact Radius from left shoulder to the ball needed at Impact. This radius, this position in 3D space of the left shoulder, low point, is critical. Once properly established movement in the body, such as a push of the backside towards the target line in transition may alter the position of the left shoulder and change the radius for the worse. For experienced golfers the brain will often, subconsciously, make a corrective move to reestablish the proper radius. A push in of the backside with a corrective pull back of the shoulders is not uncommon.

I find it very interesting that this corrective action which is totally subconscious can be explained using Homers geometry. As if our brains know his geometry while we, consciously anyways, do not.

So the "turtle" can be a corrective action taken to offset a shortening in the radius. The head and neck being attached to the shoulders, of course.

Homer would have us preview our impact alignments at Fix exactly. This relegates the high chin position at address to the scrap heap. The head should be positioned such that you are looking at the ball with a straight gaze, the eyes not looking down the cheeks or anything. This is what you will do at Impact after all. As a side bar, this is really important when putting. A high chin when putting will often have the nose blocking your right eye ball's view of the hole, meaning no stereoscopic vision, no depth perception when the head in its address position. Try a straight gaze, it helps me stop at Top too, instead of getting too long.
