Having trouble with solid contact? Try this drill and you will definitely understand the chipping angles for solid contact.
The chipping motion is a downward or decending movement into the ball.
The best way to FEEL this movement? Chip from down-hill Lie
The down-hill chip forces you to set your body on the correct angles. The entire body is on the angle of the ground. Your hips, knees, and shoulders all are angled on the lay of the land (see above).
(Incorrect) Notice how the hips-knees-shoulders are NOT on the lay of the land. This results in a hitting TOO far behind the ball. Ultimately not allowing you to create the descending angle into the back of the ball.
