…that can work on the full swing too.
Like a sniper changing the setting on his scope…
It gets you out of hitting at the ball and many other nasty things in chipping.
Eye a spot in front of the ball, swing there and let the ball get in the way. Most people’s practice swings are good and that is basically what this is. You will have extra shaft lean at the ball as you are swinging to a point in front of the ball. Even if you scoop at the spot in front of the ball, the club will be in a better place at impact.
Never, take your eye off that spot. It is a practice swing to that spot in front of the ball and the ball gets in the way.
