Ruy Lopez Marshall Attack Puzzle (Rated 1076): Win with a Discovered Attack — Tactical Chess Puzzle with Hints
This middlegame puzzle is a classic example of a discovered attack combined with a forcing check. Black’s pieces are ideally placed to exploit the loose coordination of White’s king-side and central defenders. The key idea is to remove a defender while opening a line for a rook to become active on the d-file. In positions like this, activity matters more than raw material: when one piece is pinned, overloaded, or tactically vulnerable, a forcing sequence can quickly decide the game in Black’s favor.
