Centralized King Puzzle (Rated 1145): Fork — Win Material
A fork is a tactical move that attacks two or more valuable targets at once. In this middlegame position, White must exploit an exposed king and a hanging piece while Black’s queen and rook are active but vulnerable. The key idea is a forcing check that creates a double attack, turning Black’s material advantage into a decisive material gain. This is a classic example of tactical calculation overcoming a stronger material balance.
