Rubinstein Opening Classical Defense Puzzle (Rated 815): Win a Hanging Piece — Tactical Refutation

This middlegame puzzle shows a classic tactical refutation built around a hanging piece and an exposed king. White’s active pieces create immediate pressure, and the key idea is to punish the loose bishop on h7 while keeping the black king under fire. In positions like this, material and king safety work together: one inaccurate defensive move can allow a forcing sequence that wins material and leaves the opponent tied up. The opening context fits a Rubinstein Opening structure, but the lesson is tactical awareness.
