Learn How to Win Material: Discovered Attack
This middlegame puzzle shows how a seemingly active queen can become a tactical target when a bishop move opens a line. The key idea is a discovered attack: by moving one piece with tempo, you reveal pressure from another piece behind it. Here, the position also features kingside tension and a pinned piece, so the tactic works because Black’s queen is overextended and White’s queen can suddenly attack it with gain of time and material.
