Learn How to Win with a Fork: Chess Endgame Tactic
This chess endgame puzzle shows how a seemingly active defense can collapse when one forcing move creates a tactical fork and a mating net. The key idea is to use check to drag the king into a worse square, then continue with a second forcing move that wins material by attacking two targets at once. In classical chess, these long tactical sequences often decide the game even when one side is already materially ahead.
