That’s very useful! Now…is there one for when I savagely hooked my 5 wood twice in a row for no reason whatsoever?
There's always a reason for the ball to go in where it goes.
Short answer, your hands and arms are rotating, moving "too fast" relative to your downswing / body turn. - Usually caused by
trying to hit the ball "too hard", or trying to gain a few "extra" yards.
Fundamentally the angle of the clubface relative to the clubhead motion path at impact will determine what kind of spin is imparted
to the ball and therefore what curvature results.
For a right handed golfer, when you swing the club back, the clubface will "open" relative to the ball target line until the club face is parallel
to the target-line, and the club shaft is also parallel to the target line. As you continue the back swing, the body will turn, to the extent your
flexibility allows.
On the downswing, the motion reverses, ideally with the body "unwinding" turning to the left and arms swinging down and returning
close to the address position, with the clubshaft and clubface again approximately perpendicular to the target line, and the clubface
returning to the ball.
If the arms and body
are reasonably in sync, so that the impact position resembles the address position, the ball will fly relatively straight towards the target.
**** hook ***
If the arms and hands move too fast relative to the body "unwind" on the downswing, the impact "geometry" will have the clubface and
arms "closing" (relative to the ball-target path) too quickly, and the
clubface will be turned to the left of the target line, instead of being perpendicular to the line. The result will be that the clubface will be facing left of the direction the clubhead is moving, therefore causing a right-to-left spin on the ball, causing it to curve from right to left.
The degree to which the clubhead is closed, along with how quickly the clubhead is closed, relative to the clubhead motion, will determine how quickly and how much the ball draws, hooks, or "snap hooks"
*** slice **
The slice is caused, by the opposite orientiation of the clubface / club head motion, i.e with the clubface "open" (facing right) of the
clubhead motion.
One of the most common contributing factors to a slice (or fade ..(fade-> reduced left-right curvature), is excessive tension in the trail
wrist / forearm / arm or body in general, which prevents the natural "closing" of the clubface and body turn to occur on the downswing.
The excessive tension, usually a result of trying to "hit the ball hard" (instead of thinking of making the clubhead "go fast" THROUGH the ball).
In addition or instead of just having too much trail-hand-wrist tension, the golfer can swing the club "over the top" / "across the line", instead of along the correct clubhead path. (On the "swing plane"). This over-the-top move can be caused by trying to swing the clubhead
directly towards the ball from the "top" of the backswing, instead of swinging the clubhead
down and along the club swing path.
In the latter / correct motion, the clubhead follows a "virtual hula hoop" that was set at addresss (the tilted club shaft, being the "hoop").
The club head path is then too steep and causes a "glancing" contact, to a degree, the more "off-plane" the contact, the weaker the shot.
A golfer who slices, will tend not to use their "kinetic chain" properly on the downswing, i.e. using only the hands and arms. Of course any degree of correct body / arm use is possible from the weakest arm-hand chop to the strongest swing, using all of the muscles coordinated together.
