Openings Against E4 Puzzle (Rated 824): Fork — Win Material

A fork is a tactical move in which one piece attacks two or more valuable targets at once. In this middlegame position, Black’s active knight uses check to gain time and exploit White’s overloaded coordination. The key idea is not simply attacking a loose piece, but forcing the king to respond while the knight reaches a powerful outpost. This creates a decisive material swing, showing how forcing moves can overturn the apparent advantage of an extra rook.
