Great stuff. As one who's short game is not nearly what it should be - this extra "tool" will be a welcome addition to the toolbox. I've always tended toward a divot on ALL my shots which sometimes results in those "hot" chips and pitches. This is a great explanation of how to get away from that and attain some consistency on those delicate shots.
I'm liking more and more how the various TGM cross-references work. It's becoming more clear to me why the book is structured the way it is.
I believe so. Years ago, when I was coming up, we hit these short shots with an open-open set up and traced the line left. This create a "steep" angle of attack and some divot. Decades later I am standing on the tee working on a swings and every tour player I work with has a much shallower angle of attack. No mystery to it, they are using a very flat plane inside 20 yds of the green.
