Fork Puzzle (Rated 845): Spot a Knight Fork — Endgame Tactic

This puzzle shows a classic knight fork in a practical chess endgame-like middlegame. White’s extra material looks comfortable, but Black’s active knight creates immediate tactical pressure with check and a follow-up win of material. The key idea is that a forcing move can overturn static evaluation when the enemy king and a valuable piece are aligned on vulnerable squares. In classical chess, these short tactics often decide the game before any long strategic plan matters.
