Queen's Gambit Declined: Alatortsev variation, is there a high quality resource covering this line? I am working on my opening repertoire, and I need ways to dodge the Exchange variation of the Queen's Gambit Declined with Nge2. Many masters use the Alatortsev variation to do this.

After the following moves:

[fen ""]

1.d4 d5 2.c4 e6 3.Nc3 Be7


We get the tabya of the above mentioned line. 

There are many books about QGD that cover this line, but none does that in full detail. 

Furthermore, browsing through Internet I found that there were some important theoretical novelties at the top level which were not mentioned in modern books about QGD. Unfortunately I can not provide the links now since it was more than 3 months since I last saw them.

So my question is following :

Is there a book or an online resource that covers this line in great depth with high-quality analysis?

Thank you.

Best regards.
Be7 avoids the QGD Exchange Variation and usually moves towards either an exchange with Bf4 or a regular QGD. If it's a regular QGD, there obviously won't be any books dedicated specifically to this variation as it will transpose to another well-known line.

The only pressing line then is the one with cxd5 and Bf4. I can't recall any books that focus specifically on this line in depth, but there have been many games played at the international level that use this variation. I would recommend exploring game databases like MegaBase and finding annotated games.
