The Classic Back-Rank Mate
Black's own pawns look like protection — but they're actually a prison wall.
Your Move
White to move. Find the one move that delivers checkmate.
Solution: 1. Ra8#
The a-file and the 8th rank are both completely open, so the rook slides all the way to a8. Black's king cannot move to f8 or h8 (the rook covers the entire back rank) and cannot step forward (its own pawns block f7, g7, and h7) — checkmate.
