Railroad Mate Puzzle (Rated 995): Mate in 2 — Endgame King Safety

This chess endgame puzzle is a classic example of king safety deciding everything. White’s queen and rook coordinate to create a mating net around the exposed black king, while the black pieces are too tied up to help. The key idea is that forcing checks can override material balance when the enemy king has limited flight squares. In classical chess, spotting these direct threats quickly is often the difference between a win and a missed chance.
