Sicilian Defense Brussels Gambit Puzzle (Rated 1338): Win Material — Discovered Attack
This middlegame puzzle is a classic example of a discovered attack that wins material by forcing the opponent’s pieces into a tactical sequence. White’s advanced bishop creates direct pressure on the king side and also exposes loose coordination behind it. Black must respond accurately because the key defender is overloaded and the king shelter is weakened. In positions like this, tactical refutation often comes from removing the active attacker and then using the resulting alignment to win back material.
