Well, it's good that you're taking divots.

So when you move the ball back, you still compensate to hit fat?

I went through a period of hitting it chunky for a while, so I altered my practice swing by lining up to the ball, taking a couple swings, noting where my divot started in relation to where the clubhead was at address, then I addressed the ball using the same relative setup. It seemed to stop the chubby shots for me.
