Nxd4 Puzzle (Rated 1500): Deflect — Fork

Deflection from a fork is a tactical idea in which a valuable defender or active piece is lured away from its duty. Once that piece moves, a second target becomes vulnerable to a fork or knight attack. In this chess endgame, Black uses rook activity and a forcing check to disrupt White’s coordination. The key is not merely winning a pawn, but creating a sequence where White’s rook and knight cannot protect each other effectively.
