Directing Thrust At An On Plane Aiming Point
 

Very nice, rchang! Because your simple question demands a not so simple answer, I have actually given two answers: the Basic Answer (Item #3) and the Advanced Version (Item #6). Accordingly, I've moved your post to the Advanced Section where any discussion of points #4-#6 should take place. Hang on...this is going to get a little sticky, especially for the newer students.

1. The Target Line could also be labeled the Impact Point Plane Line, and the line passing through the Low Point could be labeled Low Point Plane Line. There should be nothing mysterious about these lablels: They merely identify parallel lines that co-exist on the face of the same Inclined Plane and that pass through two defined points.

2. The Impact Point Plane Line does indeed rest atop the ground, whereas the Low Point Plane Line is in the ground, but again, on the same Inclined Plane.

3. Here then, is the Basic Answer to your question: Because the two Lines are parallel, when you point at one -- with the Tracing Right Forearm and #3 Lag Pressure Point -- you simultaneously point at the other. Therefore, it is sufficient to direct your Thrust at -- but through! -- an Aiming Point on the Impact Point Plane Line.

But, as promised, there is more!

4. The Three-Dimensional Direction of Thrust -- Downward, Outward and Forward -- will be that defined by the Delivery Path of the Hands (7-23). This concept is most clearly illustrated by Photo 10-23-A #1.

5. This Delivery Path Line of Thrust is established at Impact Fix and is parallel to the Right Forearm Angle of Approach: Note (1) the Right Forearm in Photo 10-19-A #2 is pointing directly at the Impact Point Plane Line but well in front of the Ball; and (2) that the Right Forearm is parallel to the Delivery Path. Thus, the Right Forearm Angle of Approach precisely defines:

• a. The parallel Delivery Path of the Hands;
  
  b. The Right Forearm's own Cross Line (but On Plane) Thrust through Impact; and also
  
  c. The Angle of Approach of the Clubhead (through the Inside Aft qadrant of the Ball where the eye directs the Delivery Path Thrust via Pressure Point #3 (7-3 and 7-11).

[Note: Photo 10-19-A #2 is meant to depict Drive Loading, not the Right Forearm Angle of Approach. This is the first time -- and possibly the last -- that I will use a photo for a purpose beyond its captioned intent. The reason I've done so is that there is no better photo in the book with which to illustrate this esoteric concept.]

6. So, here then, is the Advanced Answer to your question: The Aiming Point -- established at Impact Fix -- is located at the intersection of the Impact Point Plane Line and the Three-Dimensional Line of Thrust defined by Delivery Path of the Hands and its parallel Right Forearm Angle of Approach. It is precisely down that Line that you direct your #3 Pressure Point Thrust -- Down Plane through the Impact Point and Low Point until Both Arms are Straight (1-L-15).

The Angle Of The Turned Shoulder Plane Angle
 

From a down-the-Line view, the Right Forearm during Impact will be on the angle of the Turned Shoulder Plane. This Ideal Plane Angle should not be thought of in terms of an absolute degree of Tilt. Instead, it will vary:

1. From Club to Club (Steeper for the shorter Clubs and Flatter for the longer Clubs per 7-5/6/7);

2. Between Hitters and Swingers (the Shorter Shoulder Turn of the Hitter requires a Steeper Plane per 2-H); and

3. From Player to Player (the less flexible players may have a shorter Shoulder Turn and therefore use a Steeper Plane).

Establishing The Clubshaft's Forward Lean
 

The Clubshaft's Forward Lean (2-J-2) through Impact and the Right Forearm's Angle of Approach are dictated by:

1. Club design (2-G);

2. Plane Angle and the consequent Clubhead Line Of Flight (2-N-O);

2. Ball Location (3-F-7-E); and

3. The degree of Right Wrist Bend established at Impact Fix (6-C-2-A).

Plane Line Patter For TGM Junkies
 

My good friend Martee -- a Hall of Fame poster if there ever was one -- has asked for clarification regarding Plane Lines. Well, buckle up, folks, because here we go!

1. My quoted answer to rchang72 was in specific reference to his two graphics wherein the ball rested on the ground and the Low Point was in the ground. However, as Martee correctly points out, in the case of a Teed Ball there may be only 'air' divots -- this great phrase courtesy of our own PGA Professional Drewitgolf! -- or with a Ball placed precisely at Low Point only a brushing of the ground.

2. And it is possible, as Martee points out, that that the Low Point could be "other than outside the Target Line." Certainly that would be the case if the Ball is positoned at Low Point (in which case it would be on the Target Line).

3. Of course, the Target Line and the Plane Line are two different 'animals' and must maintain their respective identities. This is the case even when the Plane Line (either Impact Point or Low Point) lies atop the Target Line. Hence, the nine different Plane Line-Stance Line-Target Line Combinations of 10-5. And remember, you aways swing along (Trace) the Plane Line, but only in the Square-Square Combination of 10-5-A do you swing along the Target Line.

4. Finally, as I pointed out in my post to rchang72, in those instances where the Low Point Plane is indeed below ground, it is enough to monitor only the Impact Point Plane Line that is above ground. Then, make sure you Trace it with your Right Forearm in its Three-Dimensional, Downplane Attack Angle (of Approach) per 2-N-0 and 7-3. This will insure that the Clubhead makes its proper Down, Out and Forward orbit (Arc of Approach per 2-J-3) through the Impact Point Plane Line toward Low Point.

There now, Martee. Glad we got that all cleared up! :shock:
