I have had a terrible hiccup with the 3sk. All of a sudden, I could not play at all. The ball might go anywhere. Even sideways! In the end I had to go for a lesson. The pro immediately spotted that I was coming too far inside on the backswing. So, I was overdoing it. He has put me basically right but I have to go to the range to ingrain it again. Just a suggestion in case anyone else goes the same way.
