The Inside-Aft Quadrant -- Facts And Illusions (2-J-2 Inside-Out Impact)

With the Left Wrist positioned Flat, Level and Vertical, the Club is rotated within the Grip -- Closed for Draws and Opened for Fades -- to agree with the new Ball Location. A Ball placed back in the Stance will Draw because the Clubface makes contact with the Outside Aft quadrant of the Ball. A Ball placed forward in the Stance will Fade because the Clubface makes contact with the Inside Aft Quadrant. Strategically, knowing these simple facts can help you manage risk throughout your Round. There are times, for example, when it is advisable to position the Ball just slightly forward or back of Straightaway Location, but not necessarily enough to produce an actual curve. With trouble right, you want to make sure that if the Ball curves at all, it curves to the left, i.e., away from the trouble. So, you move it a half inch back in your Stance. Similarly, with trouble left, you move the Ball a half inch forward. Now, having taken out that little 'insurance' policy, the Ball may not curve away from the trouble, but you have eliminated the possibility that it will curve into trouble. It's the way Champions think. I thought a draw was struck on the inside aft and a fade on the outside aft of the ball. Did you mean to write it this way?

Thanks for this first post, efnef, and welcome aboard. Glad this one drew you into the fray!

My post was correct. Reference the right-hand sketch in Figure 2-B (The Venturi Effect). If the Impact Point (B) is to either side of the vertical, it will produce a 'sidewise push' -- the Line of Spin Direction (A-B) -- and the corresponding Ball Behavior (A), either a slice or a hook. Thus, a Ball Impacted left of the centerline (Inside Aft Quadrant) curves left-to-right, and a Ball Impacted right of center (Outside Aft Quadrant) curves right-to-left.

For simplicity and ease of understanding, think of the billiards stroke and the straight line thrust (linear force) of the cue stick against the cue ball. If the right hand side of the cue ball is struck, the ball spins to the left. If the left hand side is struck, it spins to the right.

But, haven't we all been told to "aim toward the Inside-Aft Quadrant" of the Ball? Isn't that where 7-3 says our eye should direct our Thrust? The answer to both questions is 'yes,' and to reconcile the apparent conflict with the Inside-Aft Slice Impact Point of 2-B, you're going to have to burn a few brain cells. It's a first-class 'seems as if' problem, and it requires work to understand it.

Remember, the Clubhead is driven down the face of the Inclined Plane by an On Plane Force (1-L #10). Because the Inclined Plane is Inclined, this Force is directed Down-and-Out through Impact until it reaches Low Point (1-L #13). This means you are going Down-and-'Inside-Out' through the Ball (Sketch 2-C-1 #3), i.e., through the visual Inside-Aft Quadrant.

However, at Impact, a Straightaway Flight (per 2-B and Sketch 2-C-1 #1) demands that the Impact Point actually be on the Vertical Center Line of the Ball. So, what appears to the player to be the Inside Aft Quadrant of the Ball is actually its Center Line. And it is through this visual Inside-Aft Impact Point -- but actually the On Center Line Impact Point -- that the player directs the #3 Pressure Point Pressure (7-3). Study carefully the sustained Center Line Impact Point in relation to the Impact Position (the dashed curved Center Line) and the Separation Position (the solid Vertical Center Line).

It may also help to remember that Clubhead Path (Clubhead Line of Flight per 2-F and 2-N-0) and Clubface Alignment (2-G) are two very different things. And it is their divergence that produces the curved Flight Path of the Ball. Study 2-D-0, 2-E and 10-5-A/D/E.

This isn't easy stuff, and you're going to have to study and meditate on it for awhile. There is no other way. Just keep coming back to it, and one day it will all make sense. Meanwhile...

Good luck!

Brian,

As Homer would say...

"Kee-rect!"

My posts referenced only the (2-B) Clubface-to-Ball Impact Points and reconciled these points with the On Plane Inside-Out Clubhead path through the "Inside-Aft Quadrant" of the Ball. This, of course, has never been done in the history of The Golfing Machine and more than answered the question asked.

However, given the subject focus and limits of reader attention, my post only encouraged students to pursue their own study of Clubhead path (2-F and 2-N-0) and Clubface alignments (2-G) through Impact.

You can't write a book with every post, but I do the best I can.
