Learn How to Exploit a Discovered Attack: Tactical Refutation
This middlegame puzzle comes from the Italian Game and shows how a single tactical shot can overturn a position even when material is level. The key idea is a discovered attack: one piece moves with tempo, opening a line for another attacker and forcing the opponent’s king and queen into a losing sequence. When the enemy king is exposed and the queen is tied to defense, tactical refutation often appears before any long-term plan matters.
