Albin Countergambit Puzzle (Rated 1240): Win the Endgame — Decisive Material Gain

This chess endgame puzzle shows how active pieces can convert a small edge into a decisive material gain. White’s queen and rook coordinate against a loose black queen and weak pawn cover, creating a forcing sequence that limits the king’s options. In classical chess, the best practical decisions often come from checking moves that improve piece activity while exposing overloaded defenders. The key is to use tempo to win material, not to chase a speculative attack.
