We've become so concerned with certain swing movements and positions that we tend to forget how the hands should use the golf club.
Fundamentally many golfers have the wrong idea about how the golf club should make contact with the ball.
Most people try to flip the clubhead under the ball and lift it up in the air.
Let the loft of the clubhead lift the ball into the air -- resist trying to lift the ball, as you want to sweep the ball from the ground.
The loft of the clubhead is designed to get the ball up and attempting to get the club head under the ball only leads to miss-hits and poor golf swings. The proper motion of the golf swing is the same as a waist high baseball swing.
The hands, wrists, and forearms rotate during the swing -- they do not stop and flip. If the hands, wrists, and forearms rotate like a baseball swing -- then your grip will undoubtedly affect how much the club rotates.
Try this: put your hands together like you're praying.
Have your hands neutral and not tilted to the left or right.
Now, turn your hands to the left so that the right hand is on top of the left hand. That is the proper rotation of the hands during the golf swing.
Now put the hands in the prayer position again -- but this time turn them a little to the right and stop.
From that position, rotate the hands to the left -- see how you have more leverage when you start from the right instead of the neutral position.
That hand position from the right, when on the golf club, is called the "strong" grip.
It is strong because it has more leverage. But it is only strong and has more leverage if it rotates to the left.
If your hands "flips" instead of rotating, the clubface will open and your ball flight will inevitably result in a slice.
Out of Bounds: Keep calm and learn the definition of insanity.
