Learn How to Win the Endgame: Zugzwang
This chess endgame puzzle is built around a long zugzwang pattern: the side to move is forced into a sequence where every active-looking choice fails. The key strategic idea is that material and pawn structure matter more than piece activity once the position has simplified. Here, a tactical shot removes the defender and converts the advantage into a winning king-and-pawn ending. The position rewards precise calculation, not general plans.
