Caro Kann Defense Advanced Pawn Beginner Puzzle (Rated 1037): Promote — Mate in 1
This puzzle highlights the power of a passed pawn when the enemy king is boxed in. Even in a middlegame-like position, promotion can be the most forcing idea on the board, especially when the new queen arrives with checkmate. The key lesson is to look for immediate promotion threats before considering material grabs or quiet moves. When the promotion square is protected and the king has no flight squares, a one-move finish can appear from nowhere.
