Ruy Lopez Fork Beginner Puzzle (Rated 918): Win a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of a tactical refutation built around a fork and a hanging piece. Black’s active knight jumps into the enemy camp with tempo, creating a direct threat against the king while also attacking a major piece. The key idea is that the opponent’s pieces are overloaded and poorly coordinated, so one forcing move can win material immediately. In classical chess, these moments often decide the game before any long-term plan matters.
