Desperado Puzzle (Rated 1800): Use Desperado — Endgame Tactical Refutation

This chess endgame is a classic desperado idea: a doomed piece becomes valuable because it can grab something on its way out. White is materially ahead, but the position is not about simple conversion; it is about using active king play and forcing moves to neutralize Black’s counterplay. The key lesson is that even in a winning material balance, you must calculate the opponent’s most active resource before assuming the game is over.
