Aravindh Chithambaram (White) Puzzle: Promote — Passed Pawn
Pawn promotion often decides a chess endgame, but the advanced pawn must be supported by tactics. Here, White’s passed c-pawn creates a constant threat while the active queen targets Black’s exposed coordination. A forcing check improves the queen’s placement and ties Black’s heavy pieces to defensive duties. The resulting pin and exchange sequence remove the blockade, allowing the passed pawn to reach the final rank and transform the material balance decisively.
