You know it was pretty much basics, the biggest thing for me was that I had far more hands and arms involved in my chipping than I realized, so he had me chipping with a ball between my arms, which helped a ton.
I was shifting my weight, which was leading to inconsistent ball contact, and also had way too much tension in my right arm. He had me let the left shoulder drive the motion and almost make the right arm limp. Lastly short backswing, long through swing.
Point is, there was nothing really ground breaking, but I needed a different set of eyes to look at it, I would have sworn I was staying on my left side and not getting handsy.
