I agree that opening your stance must allow you to clear your hips properly. normally when you open your stance it CAUSES you to fade or slice, becuase now your clubface is open to the target line (your feet). This method is actually a way tiger hits a fade. with an open stance you will be able to turn through the ball better rather then sliding, which is what im guessing your doing. also placing the ball back in your stance would only increase a fade/slice as well. think about it logically. the farther back in your stance the ball is the less time the clubhead has to square up to the ball. Thus the clubface will be open at impact.
