Slav Defense Winawer Countergambit Puzzle (Rated 1004): Win Material — Slav Defense Fork

This middlegame puzzle comes from the Slav Defense and shows how active piece play can turn into a decisive material gain. Black’s queen activity creates immediate pressure against White’s loose bishop and the pinned knight on c6. The key idea is to use forcing moves that win time, exploit the exposed king, and convert tactical targets into material. In classical chess, these positions reward calculation over general development, because one accurate sequence can flip the evaluation completely.
