French Defense Queenside Attack Puzzle (Rated 1183): Win with a Discovered Attack — Chess Puzzle with Theory & Hints

This middlegame puzzle shows how a single active knight can create a decisive tactical sequence by forcing the enemy king into a worse square and opening lines for the rook. The key idea is a discovered attack: one piece moves with tempo, uncovering a stronger threat behind it. Here, White’s heavy pieces are already aligned on open files, and Black’s king safety is compromised by loose coordination and a vulnerable queen-side structure.
