Tarrasch Defense Wagner Variation Puzzle (Rated 1254): Win Material — Decisive Fork
This middlegame puzzle comes from the Tarrasch Defense and revolves around a forcing queen check that creates a tactical fork. Black’s active queen and piece coordination exploit White’s exposed king and loose queenside pieces. The key idea is not a mating attack, but a decisive material win: the check forces a response, and that response leaves another valuable piece vulnerable. In classical chess, these forcing sequences often decide the game because they combine king safety, piece activity, and a hanging piece.
