This is my first post. I've been studying the yellow book for about six months now and this forum has been a great help in my guided struggle. Thanks to all who contribute. You guys are fantastic.

One of the things that puzzle me is the difference between the Standard Hip Turn and the Slide Hip Turn:

Standard Hip Turn per 10-14-A is a free turn in both directions with a weight shift in both directions. However, even with the Standard Hip Turn, there also has to be a sliding motion of the hips to allow the weight to shift and to create secondary axis tilt. The Slide Hip Turn per 10-14-B is defined as a free motion in both directions by the sliding of the hips with a weight shift in both directions and a delayed turn. So Standard Hip Turn is a turn with a slide, and Slide Hip Turn is a slide with a (delayed) turn? Is the difference only the amount of slide? Or its timing?

Any help appreciated.

Welcome aboard, Par71, and thanks for this incisive first post!

First, a little history: Until the 6th edition, the Slide Hip Turn was defined as a Slide (in both directions) with no appreciable Turn.It is the action demonstrated in Photos 10-14-B #1 and #2. It is also the action that unfortunately remains described in the Chapter 11 summary (11-14-B). This oversight originated with Homer Kelley and has yet to be corrected by the current publisher.

As you have noted, the amended definition in the 6th and 7th editions is a slide with a delayed turn (in both directions). This new definition differs from the Standard Hip Turn in that it emphasizes a more exaggerated Slide parallel to the selected Delivery Line (normally the Square Plane Line / Target Line) prior to the Turn.

An example would be the Slide Hip Turn of Colin Montgomery. Take a look at the linked Swing Sequence, and the differentiating features of Slide versus Standard will be readily apparent. Note especially how the exaggerated Hip Slide (even though coupled with a Delayed Turn) moves Colin's right leg to vertical in the Backstroke and left leg beyond vertical at the Finish. http://www.todaysgolfer.co.uk/Golf/v...ence-Golf-Tip/

Personally, I use and teach the more conventional Standard Hip Turn of the first six editions, even though the posthumously published 7th edition now lists the Slide Hip Turn as the 14th Component Variation (in both the Drive and Drag Loading Basic Patterns / 12-1-0 and 12-2-0). However, if a student came to me with a well-executed and integrated Slide Hip Turn, I would not change it.
