Learn How to Promote: Underpromotion Mate
This chess endgame puzzle shows why promotion is not always the best choice. Even when a pawn reaches the last rank, the strongest move may be to promote to a lesser piece if that creates immediate mate or avoids stalemate-like resistance. In classical chess, these motifs often appear when the enemy king is boxed in and your advanced pawn controls key escape squares. The position rewards precise calculation over material greed.
