After Kg4,Be7 then eventually to f5 with either Kf5,pxf4 - Kxf4, whatever or Kg4 pxp, Kxp whatever-- White's king gets to f5 and blacks king is cut off from getting back there. That seem to be the purpose of Kg4 to begin with. To keep the black king off of f5. After that it looks like an easy win for white. Pxp to start with allows the black king access to f5??
