Learn How to Spot a Discovered Attack: Decisive Material Gain
This middlegame puzzle comes from the Semi-Slav Defense and shows how a single tactical idea can overturn a position even when the material looks balanced. The key motif is a discovered attack against the king-side, where a forcing bishop move opens lines and creates immediate pressure on the enemy king and queen. Once the defender is dragged into a capture, the follow-up wins material because the queen is left exposed and the king’s shelter is weakened.
