Any resources on long castles (O-O-O) in Queen's Gambit Declined?

Hi chess-friends,

Does anyone know of any opening books or other resources that discuss long castling in the Queen's Gambit Declined, preferably from White's perspective. I know it is not objectively very good but I would like to learn more about the kinds of positions it leads to since they are quite rare in chess.

Here is a typical position that is reached after:

1. d4 d5 2. c4 e6 3. Nc3 Be7 4. Nf3 Nf6 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5 8. a3
Nc6 9. Qc2 Qa5 10. O-O-O:

I’m not sure of books, but you should look at the games of Daniil Dubov and Shakriyar Mamedyarov

A whole book just on that?  No!

Objective books on the Queen's Gambit Declined, like Sadler's book, with have a chapter on 7.Qc2 (instead of 7.Rc1), and about half of those games see White casting Queenside.  However, it is a Bg5 line, not Bf4.

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 O-O 6.Nf3 Nbd7 and now 7.Qc2.

Typically, 7...c5 should be answered by 8.Rd1 and slower moves, like 7...c6?!, should be answered by 8.O-O-O.  In this line, often ...h6 is answered by h4.

Thank you for the tip. I know that Mamedyarov plays a few interesting games in QGD with long castling but I haven't really studied Daniil Dubov as a player.

The OP's line was quite popular in top level chess for awhile, after being played in Speelman v Short Candidates match. Guess it would be covered in John Cox's book on Queen's Gambit declined for black.

Think castling queen-side is quite reasonable in several queen's gambit declined lines, but not very popular with 1.d4 club players, because they are often very safe players.

I don't think queenside castling is normal in QG, but I don't know because I don't play it.

Really cool thing

surely interesting idea.. hmm in the first look it seems dangerous and weak. but on the other hand some top level players played it some said. i definately should look into it.. as a QG player myself. i'm curious about whats the idea behing it now.

I have been experimenting with it without knowing any theory, basically coming up with a way of playing that I believed in. The results have been varied. As you say, it is difficult to play for White (and Black). Perhaps not a coffee house opening but I believe that fundamentally it is wrong to castle queen side. Good winning attempt nevertheless.

From the reviews it appears others also have a lot of praise about the book. I will see if I can find one used.

No one is going to fall for your nonsense.

Minority attack is useless? Isn't that the main weapon for White? If you exchange using knight instead of pawn... you can get a good Semi tarrasch position.
