Fork Advanced Puzzle (Rated 670): Fork — Endgame Tactics

A fork is a tactical pattern in which one piece attacks two or more valuable targets at once. In this chess endgame, the knight can exploit the exposed king and an active rook, creating a decisive material gain. The key is recognizing that a check can also be a forcing attacking move, especially when the opponent’s king and rook are aligned with a strong knight outpost. Once the fork appears, White can simplify into a winning position.
