Blackmar Diemer Gambit Accepted Sacrifice Intermediate Puzzle (Rated 1337): Spot a Mate in 2 — Kingside Attack
This middlegame puzzle comes from the Blackmar-Diemer Gambit Accepted, where rapid development and king safety matter more than material count. Black’s attack is built around a direct kingside assault against a vulnerable white king shelter. The key idea is to exploit the exposed king, overloaded defenders, and the weakened dark squares around the white monarch. When the pieces coordinate on the h-file and g-file, a forcing tactical sequence can end the game immediately.
