Latvian Gambit Mason Countergambit Puzzle (Rated 1116): Exploit Kingside Attack — Decisive Material Gain

This middlegame puzzle shows how a direct kingside attack can turn into a decisive material gain when the enemy king is exposed and key defenders are overloaded. Black’s pieces are active, White’s king shelter is weakened, and the queen and bishop coordinate on forcing lines. The idea is not slow maneuvering but a tactical refutation that uses checks and captures to break the defense and win the exchange of pieces on favorable terms.
