L'Ami on this 11.Nf4 move: "I believe Black is ok, starting with 11...Nd7 12.Qd1 there are some options. 12...g6!? invites 13.Nxg6 fxg6 14.Bxg6 Nf8 15.Qh5 Nxg6 16.Qxg6+ Kh8 when the threat of ...Bd6-f8 means White has to give a perpetual.

More ambitious is 12...Nf8 13.Qh5 Bxf4 14.Bxf4 h3 15.gxh3 Be6 and ...Qd7 next, or in this line 13...Qc7!? provoking some weaknesses. 14.g3 Qd7 with a very unclear game."

And Sielecki:
"This is an interesting idea, but after 11.Nf4 Nd7 12.Qd1 Nf8 13.Qh5 we reach a position that has been tested a lot, actually. Black has some good options, but it's tough to say what's best. Even the ultra-simple 13...Bxf4 14.Bxf4 h3 seems to be playable.
A more sophisticated one is 13...Qc7 14.g3 b6, which I like."

The line with 11. Nf4 and 12. Qd1 is an excellent sideline choice for White because Black must exactly know what the antidote is: g6 is for sure wrong which can be seen in the results of the games and more objectively with engines.

Franceco Rambaldi covers the Nf4+Qd1-line in his book "The Caro-Kann revisited" from 2020 and calls it "surprisingly dangerous" and "fully independent from the from the 11. h3 variation". The second comment is very important because Black must react in a way which is uncommon in this opening line. By the way: Lars Schandorff does not mention the line in his newer Caro-Kann book from 2021 although the Rambaldi book is one of his references.

So what is the correct plan? The white queen wants to sneak behind the black pawn on h4 which needs now the assistance of the black queen. Blacks plan has to be
- play Nf8 to protect h7 and to make room for the black queen
- bring the black queen to d7 so that Qg4 is possible, but ...
- ... because of h3 this needs to be prepared by playing Qc7 first to make white play g3

The typical move order is therefore 10. 0-0 h4  11. Nf4 Nd7  12. Qd1 Nf8  13. Qh5 Qc7  14. g3 Qd7 and White can currently not take on h4 because of 15. Qxh4 g5 back wins and 15. gxh4 Bxf4  16. Bxf4 Qh3 with at least equality for black.

Logical moves for White are therefore after 14. ... Qd7 e.g.
- either normal development e.g. 15. Bd2 and now the dynamic  Bxf4  16. Bxf4 g5  17. Bd2 Qh3 = 
- or moving the Nf4 away so that Black has to take on g3. Rambaldi recommends to go to an endgame with 15. Ng2 hxg3  16. hxg3 Qh3 (c5 is also an option which he does not mention).

Here is one example game. It is on chess.com titled tuesday 2550 level but just a blitz game with some inaccuracies ... and a funny ending which shows that also on that level you can blunder instructively under time pressure in a basic 2 versus 2 pawn endgame  Smiley

From Black's perspective, 12...g6 seems very risky. Perhaps 12...Nf8 with the idea 13.Qh5 Qc7 is safer, with h4 not really hanging, and after 14.g3 Qd7 seeking for exchanges (Stockfish suggestion)

Thanks, that's an exciting line.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.
