Attraction Puzzle (Rated 1231): Win with a Fork — Crushing Middlegame Tactic

This puzzle is a classic middlegame tactic where a seemingly active position hides a forcing sequence based on attraction, check, and a crushing fork. The key idea is to lure a defender onto a vulnerable square, then use a forcing move to create a double attack that wins major material. In practical classical chess, these patterns often appear when pieces are overloaded and the king’s shelter is weakened, making calculation more important than long-term strategy.
