Try under handing a golf ball...

That's as bad an idea as Hogan's sidearm/underhand basketball pass. It's called steering. Chips or full shots, you should drive PP#3 down-plane towards the ball with the right shoulder, if Swinging, or with the right tricep, if Hitting. You should never make a hand effort toward the target! If you're going to throw a golf ball in order to get the correct swing feel, it should be toward the one on the ground.
