Blackmar Diemer Gambit Pietrowsky Defense Puzzle (Rated 1119): Win Material — Discovered Attack
This middlegame puzzle shows how a discovered attack can turn king safety into a decisive material edge. White’s active queen and bishop coordinate against the exposed black king, while Black’s queenside pieces are awkwardly placed and one key defender is vulnerable. The point is not just to check the king, but to use forcing moves that improve the attack and win material at the same time. In sharp classical chess positions, activity often matters more than the extra pawn.
