Rapport Jobava System Hanging Piece Intermediate Puzzle (Rated 1017): Spot Mate in 1 — Queen Sacrifice
This middlegame puzzle is a classic example of a forcing tactical finish where king safety outweighs material. White’s pieces are active, the black king is stuck in the center, and the back rank is vulnerable because key escape squares are covered. The position also features hanging pieces and loose coordination, so a direct queen-based finish becomes possible. In practical play, these patterns often appear when the opponent’s last move leaves the king exposed and a major piece undefended.
