Learn How to Promote: Pawn Promotion
This chess endgame puzzle is built around a classic advanced pawn race, where the side with the most dangerous passer can force decisive material gain. The key idea is to use the rook actively: check the king, cut off counterplay, and then convert the passer at the right moment. In rook endgame positions, activity often matters more than raw material, especially when one pawn is only a step from promotion and the opponent’s rook is poorly placed.
