Sacrifice Puzzle (Rated 1470): Spot Mate in 2 — Queen Sacrifice

This middlegame puzzle is a classic forcing sequence built around king safety and a sacrifice that drags the defender away from the key square. Even though White is materially ahead, the position is decided by calculation, not material count. The attacking side uses a direct check to force a capture, then finishes with a second rook check on the same file. Patterns like this often appear in classical chess and tactical game reviews where the king has limited escape squares.
