Learn How to Exploit a Discovered Attack: Tactical Refutation
This middlegame puzzle comes from the Sicilian Defense, Bowdler Attack, where active piece placement creates a tactical refutation against an exposed king. White’s forces are coordinated around the center, and the key idea is to use a forcing check that also uncovers pressure on loose black pieces. The position rewards calculation because the king is still in the middle, the bishop on c2 is vulnerable, and tactical motifs like discovered attack and discovered check decide the game.
