Well, getting into a defensive position and letting the perp come to you has been shown time and again to be the most effective strategy by far, and I do not know why anyone would call it "insane".
All real experts I know of recommend that approach.
I've decided, if possible my "last stand" will be at the top of the inside stairs. If needed I can prone out, stand, or kneel behind a corner wall which has a triple stud support corner.
If I can't pick the time of the fight at least I can pick the place.
