Blackmar Diemer Gambit Rasa Studier Gambit Puzzle (Rated 1649): Sacrifice on h7 — Decisive Material Gain

This puzzle shows a classic attacking pattern in the opening: a bishop sacrifice on h7 to pull the king into the open and expose the dark squares around it. White already has strong piece activity and development, so the sacrifice is not random—it is supported by a knight jump and a follow-up attack on the king. The key idea is to use attraction and a discovered attack to win the queen and leave White with a decisive material edge.
