At bullet time controls, this is more than sound. Reacting to an attack burns clock time, even if the defense is accurate.
At slower time controls and vs. a stronger opponent, I'd still think there' s some venom in this sacrifice, though I don't see a forced win.
This is a recent bullet game I played. Since we each only start with a minute on the clock I decided to play agressively as I could once development was near completion. I gave up my bishop for 2 of the pawns near his king, but would it have been worth it vs an opponent with greater strength + greater clock?
