Learn How to Promote: Pawn Promotion
This middlegame puzzle is built around a classic promotion attack: a passed pawn, active rook, and exposed king combine to create a forcing mating net. White’s pieces are coordinated to overload the defender and open lines near the black king. The key idea is that a sacrifice can drag a pawn away from its defensive post, after which the rook and promoted pawn work together to finish the attack. It is a strong example of how pawn promotion can be the final tactical resource in classical chess.
