To learn a solid takeaway, get into an address position without a club. Level right wrist. Right forearm flying wedge in place.
clap your hands, leaving the left hand and arm at impact. Let your right hip move 'back' (clear it)
As you make that clapping motion bigger, allow the right hand to turn so that at the 'top', you are in a karate chop 'on plane' position with the pinky side of the right hand.
practice returning both to a 'clap', as well as a 'karate chop' back to the left hand. The 'karate chop' will show you how the right shoulder moves down plane.
