It's called the Wayward defense.
Definitely post games where you use this to defend the Wayward Queen Attack.

And White cannot lose if <2000, how does Black win if rated >8000?
Aha, it starts with the super duper queen sacrifice (7.Qg4) and continues with the the super duper knight en prise but quick and short castle anyway (8.O-O).
That's super duper stuff 👍
