Learn How to Spot a Discovered Attack: Tactical Refutation
This middlegame puzzle shows a classic tactical refutation in the Sicilian Defense, Smith-Morra Gambit Accepted. Black’s pieces are coordinated around White’s king and loose kingside pieces, so one forcing move can create a discovered attack and win material with check. The key idea is that a capture on f3 opens lines for the queen and removes a defender at the same time. In practical terms, this is a decisive material gain, not a mating pattern.
