Learn How to Promote: Discovered Check
This middlegame puzzle shows how a passed pawn can become a tactical weapon, not just a long-term asset. White’s attacking pieces are active around the enemy king, but Black’s counterplay is based on forcing checks and promotion threats. The key idea is to recognize that a promotion race can be combined with a discovered check, turning a seemingly defensive resource into a decisive tactical sequence. In chess endgame and classical chess positions alike, advanced pawns often decide the game when the king is exposed.
