The Topic of the Video was "Hitting the Ball Straight using a Driver requires a different Swing than when using an Iron".

We (a few) know that Striking the Ball with an Angular Force so that the Ball responds as though it were struck by a Linear Force, requires the Clubface to be Square to the Angle of Approach at Contact (create the Line of Compression) and rotate that Line of Compression to become square to the Target at Separation. Without equal pressure on the Horizontal Plane (the Ball and Clubface rotate around the Impact Point), the Ball will develop Side Spin.

In a nutshell. If the Clubhead is traveling 5 degrees inside-out and the Impact Interval is 1/4" (5 iron), how do you Rotate 5 degrees in that short of a distance?

If you Strike the Ball with a Clubface Square to the Target and at separation it remained square to the Target, then How do you manage equal lateral pressure on the Ball if the Clubhead is traveling as little as 1 degree from inside-down and out?
