One Path of Deceit in the Advance Variation of the Caro-Kann: The Knight of Doom

Hello everybody. This is a little post in which I'm going to discuss a very dangerous choice that people may play in the Caro-Kann.
 I always loved the Caro-Kann defense. In fact, is still a favorite of mine in OTB games and I think is a good response to 1.e4 for people who want to train their positional game while having a solid pawn structure.
 The Advance Variation in the Caro-Kann is quite frequently played, and like a lot of players, 3. ... Bf5 is my favorite continuation.  When playing against 4. Bd3, normal play continues with an exchange of light-squared bishops in which although White gets some attacking initiative, while Black gets a positional edge based on the control of the light squares, and a rock-solid pawn structure.
 Nevertheless, when I was a youngester I didn't like the idea of exchanging pieces so quickly, and after an inmature analysis, I came up with this variation:

Things look good for Black in this seemingly strong theoretical novelty. But then I discovered that White can unleash a vicious attack at a very affordable price: 6. e6!, a variation which I like to call "The Knight of Doom Attack". Like musician Danzig said, "Even in heaven you can find a door to hell". Analysis is inserted in the next diagram.

Declining the sacrifice moving the f pawn:

As you can see, 4. ... Bg6 against the 4. Bd3 attack is kinda unsound. I hope you liked this article!

PS: I'm going to make a video discussing this attack in my YouTube channel (Spanish language).
