My thoughts were
exf6 gxf6 then not f5 but simply Kd4 and Blacks best reply is Kf5, I thought Black would be in Zugzwang after that but it appears not. My Kd4 idea does work after gxf6 though, because then Kf5 exf6 Kxf6 Ke4 and that is the zugzwang we are after. Your f5+ line missed fxe5+ after Kf4

I shared this on the Clermont Chess Club facebook page, and it picked up additional positive press. We even talked it at my club when I went today. Definitely a great example and teaching position.
