You will read article after article in golf magazines about how to fix a slice.
Unfortunately, very few conventional golf swing instructions on how to cure a slice do the job. None address the underlying cause of a strike.
The golf swing tips you read about in the magazines and see on television attempt to address the symptoms associated with a slice rather then the real cause of a slice.
The underlying cause of a slice is the way the left hand is gripped on the club (for right-handed golfers) when assuming either an overlapping, interlocking or baseball style of grip.
Since the conventional golf method of gripping the left hand on a club places the club diagonally across its fingers and palm, the instant the right hand is gripped on the club the clubface will be rotated to a slice alignment.
In addition, the first move of any body part after initially gripping a club with either an overlapping, interlocking or baseball style of grip will rotate and lock-in a slice ball flight alignment. This means almost any body part movement after initially gripping the club, including partially un-gripping and re-gripping the club.
To fix a slice you must have at least two body part movements after initially gripping the club. The second body part movement will rotate the alignment and swing path of the clubface to a square position. It also will lock-in such a square alignment.
These body movements will lock-in a straight ball flight alignment and enable you to hit a golf ball straight.
However, many beginning golfers as well as recreational and weekend golfers do not routinely make at least two body part movements after assuming their grip. The routine for many is to address the ball, align the shoulders parallel with the target line, center the clubface behind the ball and grip their hands on the club either with an overlapping, interlocking or baseball style of grip, and then, execute a simple golf swing.
This routine rather well guarantees a slice golf shot assuming sufficient club head speed unless the clubface is manipulated in some way during the golf swing to rotate it to a different alignment.
Of course, manipulating the club during the golf swing to re-route the clubface to a square alignment at impact is what many conventional instructors teach which only goes to prove the clubface was in a slice alignment at the beginning of the swing
If not, there would be no reason to manipulate the club during the golf swing.
In each of my more than 100 ways to hit a golf shot as straight as a laser beam, there are precisely two body part movements after initially gripping the club with either an overlapping, interlocking or baseball style of grip or, two body part movements after gripping the left hand on the club.
In either case, such movements rotate the clubface from a slice alignment to a square alignment.
The other way I instruct to fix a slice and produce golf shots as straight as a laser beam is to modify the conventional overlapping, interlocking or baseball style in some way so the left hand is placed squarely instead of diagonally across its fingers and palm. Such revolutionary gripping techniques are covered in my book, How to Lock-In a Perfect Grip.
