Samuel Sevian (Black) Puzzle: Checkmate — Mate in 1

This position is a sharp tactical lesson in king safety. Black’s king is exposed in the center, while White’s queen and bishop coordinate across key squares around the king. The main idea is to recognize when the opposing king has too little shelter and too few legal replies. Although the position contains endgame-like material and passed-pawn possibilities, the immediate priority is a forcing checkmate. Strong piece coordination can make king activity a liability rather than an advantage.
