I was being mindful of my positioning last night, and keeping in mind the inner leg advice. I was aware, and my opponent commented that my BH chops were in front of my body. His comment was that his meant they popped up, and I didn't have much room for a full chop, so couldn't impart much spin. I did try to move the right foot and then left foot, and then chop the ball *beside* my body, rather than in front of. I still need a lot of practice at this.
