Queens Gambit Declined Janowski Variation Puzzle (Rated 1153): Win Material — Discovered Attack

This middlegame puzzle shows a classic discovered attack pattern in the Queen's Gambit Declined. White’s pieces are coordinated around the enemy queen and king, and one forcing move creates immediate tactical pressure by opening a line while also checking the king. The key idea is that a capture can be more than a trade: it can uncover a stronger attack on a valuable target and force the opponent into a losing response. In practical play, these motifs often decide the game through decisive material gain.
