Learn How to Underpromotion: Pawn Promotion
This chess endgame puzzle is built around a promotion race where both sides have dangerous passed pawns. The key idea is that promotion is not always about making a queen: sometimes the strongest move is an underpromotion that creates a forcing tactical sequence. Here, the advanced pawn and the enemy king’s limited squares combine to make the promotion choice decisive. In classical chess, these endgame motifs often decide games instantly because one tempo can change everything.
