I play the Caro-kann quite a lot, after E4,C6,NC3,D5,NF3,DXE4,NXE4 i play Nf6, i think that is the main line and the move Stockfish recommends.
This is indeed one of Black's best attempts- usually strong players refrain from taking at f6, and play 5.Qe2.
In this line as black I'm not especially fond of 6...Qd5 and I've been trying to make 5...Nxe4 6. Qxe4 Qa5!? work which Riazantsev and Grandelius have played. I imagine black's a little worse but I'd love to know your thoughts on it.
Hey, I like this, gonna give it a few tries. I guess top GMs think it doesn't fight enough? hmm, I dunno.
Just the opposite. Too chaotic for them.
