Attraction Intermediate Puzzle (Rated 1445): Crushing Fork — Decisive Material Gain

This chess puzzle is a classic middlegame tactical refutation where active rook play and king pressure outweigh the material balance. The key idea is attraction: one piece is lured onto a square where it becomes vulnerable to a forcing sequence. Once the king is drawn into the line, the follow-up creates a crushing fork that wins major material and leaves the defender helpless. In practical classical chess, these motifs often appear when open files and exposed kings combine.
