Club face release is not some mystical search for enlightenment, but it
is an essential fundamental that every single golfer must learn to do.
Every single pro's swing is different, yet the one single thing they all do
and can control very well, is the face release.
If you don't release/rotate the club face through impact enough, you'll only hit
a push/fade/slice or flop it altogether.
Obviously now if there is too much release through impact you'll draw/hook.
Knowing how to draw it strong is key when combined with a proper weight
shift toward the front foot on the down swing. The result is the "distance
with no effort shot" that you see on the pro tour.
Without learning to release the club face you'll never learn to draw the ball,
stick the ball on the green, add so much back spin so the ball rolls back to
the pin and lastly, crush it a controlled 280-300yds out of the box.
as my instructor always told me...(being a right handed golfer)
"if you fully release the face it is impossible to hit the ball right"
"if you properly shift your weight forward it is impossible to hit the ball left"
"when you can do both together you can only hit a powerful pure straight"
