Bird Opening Sacrifice Intermediate Puzzle (Rated 1179): Spot a Mate in 3 — Kingside Attack
This middlegame puzzle is a classic example of a forcing kingside attack where king safety matters more than material. White’s queen and rook coordinate to create a mating net around the black king, and the key idea is to use checks that restrict escape squares. The position also shows how a pinned pawn and an exposed king can turn a seemingly balanced classical chess position into a direct tactical win.
