this queen sac felt brilliant at the time, especially in blitz! The engine classifies it as best although imo it has a sacrifice leading to a decisive advantage. Whites only move is to trade down to a losing endgame but if he tries anything else like what you saw here it’s mate or a worse position. The whole game this guy was very defensively minded so I had to get very creative to break through his defenses when he tried to establish some counterplay.
