This is a study by Cheron. It’s White to Play and Win. How would you go about it?
Sometimes even studies are remarkably simple in their execution. 1.Ng7+! Nxg7 2.h6 and the pawn can’t be stopped. BTW, Black can refuse to take the knight and head to the corner and hope for stalemate, but (and this happened in a tournament game I once played, but the key is for White to only push the pawn to h6, not h7, with the king and bring the knight up to force the king out of h8 with a check followed by h7.
