Rapport Jobava System Fork Intermediate Puzzle (Rated 852): Mate in 2 — Queen Sacrifice
This middlegame puzzle is a classic example of a forcing mating attack built around king safety and piece coordination. White’s queen and knight work together to exploit weak dark squares around the black king, while the black rook on e8 becomes a tactical target. The key idea is that a forcing check can drag the king onto a vulnerable square, after which the follow-up finishes the game immediately. In classical chess, these short combinations often begin with a sacrifice that opens the path to mate.
