Blackmar Diemer Gambit Declined Discovered Attack Intermediate Puzzle (Rated 1614): Exploit a Kingside Attack — Decisive Material Gain
This middlegame puzzle shows how a direct attack can outweigh a material deficit when the enemy king is slightly exposed and key defenders are overloaded. White’s active queen and rook coordinate with the bishop to create a forcing tactical sequence that wins material and keeps the initiative. The idea is not a random sacrifice, but a calculated breakthrough that opens lines, removes defenders, and turns piece activity into a decisive advantage.
