Grunfeld Defense Russian Variation Puzzle (Rated 1021): Win Material — Discovered Attack
This middlegame puzzle is built around a classic discovered attack idea: one piece moves to open a line for another, creating immediate tactical pressure. The key is that the apparent target is not the whole story; the hidden attacker becomes the real threat. In positions like this, active pieces, loose defenders, and king safety often combine to produce a decisive material gain. The best move sequence exploits a hanging piece and forces the opponent into a difficult recapture.
