Set up, a Basic Part of the Swing Map, affects your entire swing
Since the face of the club controls the direction of the shot, we can hit controlled draws and fades by keeping our clubface at the target and then moving our set up and alignment slightly left or right
Possibly the worst advice anyone can get is to keep their head down during the swing, this completely restricts the turn, you want to keep your head centered not down, so that you can make a centered pivot with no sway or spine angle break down
