Indian Defense Polish Variation Puzzle (Rated 993): Win Material — Discovered Attack
This middlegame puzzle shows how a well-timed kingside sacrifice can open lines and create a decisive material gain. White’s pieces are already active, and the black king’s shelter is slightly loosened, so the key idea is to force the king to react while the queen and bishop coordinate against loose defenders. The position rewards pattern recognition: when the opponent’s queen is overextended and the king is exposed, tactical refutation often comes from a forcing check that reveals a stronger follow-up.
