How to destroy the Caro-kann

I've been playing this opening against the caro for quite some time, with about 80% win rate.

This knight sacrifice is known as the alien gambit. Clearly there are many devastating traps despite the piece sacrifice. I tried to show most of the key ideas, as well as some of the traps or continuations people may play. Note that I haven't checked all of these lines with the engine, primarily the longer continuations so they may be a bit wrong. Yet it is still an effective weapon to use against the caro (even at the 1800 level and maybe a bit higher).

For those of you who play the caro, do you guys see this gambit often? If so, how would you try to defend against it?

Edit: I just realised it saved a move I briefly looked at instead of the correct line. 14.Be6 allows Kd6 winning a piece. So instead you play 14.Kd1 with plans to continue the attack with your h1 rook.

On move 7 where white gives Bc4 check , you do realize right you lose all advantage if your opponent just does e6?

Note that in all the lines in the gambit I recommend, perfect play for Black in the Accepted lines can't ever guarantee a winning advantage, only about a -0.5 at worst, meaning you should always have drawing chances at absolute worst.

This gambit also has the benefit of sharing the same move order with the 2. Nf3 Breyer queen trade line which follows 4. dxe4 Qxd1+ 5. Kxd1 and is Lc0's recommendation for the strongest line against the Caro-Kann in general. It's the perfect addition to a repertoire: incredibly simple, zero theory, solid, and very intuitive and easy to play. If you use the gambit as your main weapon in club play and start to see worse results against players who come prepared specifically against that line, you can always pull the queen trade line out of your pocket and surprise them with an opening choice as strong as the Anti-Marshall.

Are you able to explain what the point is of the endgame variation? I don't play the Caro anymore but when I did, I didn't even have an entry for that in my repertoire file, because it looked so harmless. I don't really understand why it isn't completely equal, but it scores amazingly well for White in practice.
