Antoaneta Stefanova (Black) Puzzle: Fork — Win Material

A fork is a tactical move that attacks two or more valuable targets at once, often with a knight. The strongest forks frequently come with check, forcing the king to respond while another piece remains vulnerable. In this chess endgame, White uses an active knight to create a forcing threat against the king and a rook. The idea turns Black’s material advantage into a decisive material gain through coordination, timing, and accurate calculation.
