Underpromotion Chess Puzzles

Underpromotion is the choice to promote a pawn to a piece other than a queen, usually a rook, bishop, or knight. While queen promotion is the most common and strongest in many positions, underpromotion is used when a different piece gives a better tactical result. It is a practical concept for intermediate players because it often appears in forcing endgames and sharp tactical puzzles.

To spot underpromotion chances, look for positions where promoting to a queen would stalemate, allow perpetual check, or miss a direct win. Also check whether a knight promotion gives check, forks the king and queen, or controls key squares that a queen cannot. In your games, always ask whether the strongest move is really a queen, or whether a lesser piece wins faster or more safely.
