Knight Endgame Puzzle (Rated 1328): Win a Knight Endgame — Crushing Defense

This chess endgame is a classic example of how one accurate defensive move can completely change the evaluation. Even when the material looks balanced, active king placement, passed pawns, and piece coordination decide everything. In knight endgames, a single loose piece can become a tactical target, and the side to move must calculate forcing exchanges before committing to a plan. The key idea is to use simplification to convert activity into a winning pawn race or a decisive king-and-pawn ending.
