Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a direct tactical shot on the queen. White’s bishop is lined up with the enemy king and also masks the queen’s pressure on the d-file, so moving it creates a powerful double threat. The key idea is that one piece can be doing two jobs at once: checking the king and uncovering an attack on a more valuable target. That kind of coordination often decides classical chess puzzles.
