Defensive Move Intermediate Puzzle (Rated 1065): Win Endgames — Crushing Defensive Move

This chess endgame is a classic example of how a single defensive move can turn into a decisive tactical resource. The key idea is to use king activity, passed pawns, and piece coordination to create a forcing sequence that leaves the opponent’s king short of safe squares. In classical chess, endgames often hinge on tempo, and here the active king and knight work together to exploit weaknesses around the enemy king and the advanced pawn structure.
