Ruy Lopez Marshall Attack Puzzle (Rated 856): Crush with a Discovered Attack — Tactical Win
This middlegame puzzle is a classic example of a crushing tactical sequence built around a discovered attack and king-side pressure. Black’s pieces are coordinated to exploit the exposed white king and the loose queen on d3, while White’s own attacking setup leaves key squares and pieces vulnerable. The position rewards seeing forcing moves first: checks, captures, and threats that open lines. Once the king is dragged into the attack, Black can win material and keep the initiative with a decisive follow-up.
