Magnus Carlsen (White) Puzzle: Win a Fork — Knight Checks

A knight fork is especially powerful in a chess endgame because each piece matters and king placement is often exposed. Here, the active knight can leap to a protected central square with check, attacking the enemy king and rook at once. The check removes the opponent’s freedom to save the rook immediately, turning a seemingly balanced position into a decisive material gain. This is classical chess calculation: identify forcing checks before assessing slower passed-pawn plans.
