Discovered Attack Puzzle (Rated 1456): Win with a Discovered Attack — Middlegame

This puzzle is a classic example of a discovered attack in the middlegame, where one piece moves to open a line for another and create immediate tactical pressure. The key idea is that the opponent’s king and queen are vulnerable on the same file/diagonal, so a forcing sequence can win material fast. Even though the position looks like a chess endgame in structure, the tactics are pure classical chess: active pieces, open lines, and a decisive tactical refutation of the last move.
