Blackmar Diemer Gambit Accepted Sacrifice Intermediate Puzzle (Rated 1343): Mate in 2 — Queen Sacrifice

This middlegame puzzle is a classic mating net built around king safety and a forcing queen sacrifice. White’s heavy pieces are aimed directly at the black king, and the key idea is to remove the defender that keeps the h-file and h7 square protected. Once that shield is gone, the rook can join the attack with a direct checkmate pattern. The position rewards players who notice how active pieces, open lines, and a vulnerable king can outweigh material.
