Queens Gambit Declined Question

Hello, I would really aprieciate if an experianced player could give me an answer to this question. Sorry I do not know how to insert a diagram I need to learn that so I will write the first 7 moves in algebric format.

I played a game against white in the queens gambit declined and by move 7 I thought I must have made a mistake but when I put the game through chess.com computer analysis it said that all my moves up to move 7 were book moves which shocked me as white is clearly better.

Here are the moves

d4 d5, c4  e6, Nc3 Nf6, cxd5 exd5, Bg5 Be7, e3 Bf5, Qb3.

Here I see a few problems for black as there is a double attack on b7 pawn and d5 pawn.

The computer said the best 7th move here is Nbd7. What is to stop the queen taking the b7 pawn or Nxd5 , I must be missing something here , the theory does not make sense to me.

Any ideas or insight would be very much aprieciated.

Thankyou

8. Nxd5 Nxd5 9. Bxe7 Nxe7 wins a piece for Black, or 8. Nxd5 Nxd5 9. Qxd5 Bb4+ followed by Qxg5.

Those are the other two lines for Black. TY blueemu.

Would somebody tell me and the OP how you put up those diagrams,for chess sake!pun intended.

Can you see the first little chessboard icon, just above, when you enter your text for Posting Your Reply? Click on that and follow the instructions...

This is how my game ended up and I resigned on the spot lol.

I do not know why the moves were not put in???

Thanks very much for all the help chaps, I still do not understand why the queen cannot take b7 after Nbd7 due to the queen trap only being affective if the queen goes to check the king, what if she retreats off to a6???

With my limited understanding of the queens gambit please go easy on me. It looks to me that black is worse right from the beginning in this line yet it's a book move. Pls could someone explain???

Thanks

I don't know any theory of it, but black looks down a pawn but will be ahead in development. The white queen is doing nothing and will have to move again, black has an open b file he will be able to put a rook on.

I think you meant Qxb7. I do not see a queen trap after 8...Qxb7, I know the trade of Bxf6 Bxf6 may be the preferred line first yet 8...Qxb7 bargain a pawn and lose tempi but still worth it until someone can explain me why not. 

Why ask a question and ignore the responses? You think the tempi is worth it, but it's an important factor in the opening.

Playing Qb3 before trading on f6 is fine and I think actually more common.  The idea that Black position is so horrible after the moves discussed above is not exactly true, but he stats for the QGD exchange variation are what they are for a reason, white has space, and both center pawns.  The queen is blocking the pawns for the minority attack which is a major theme in the QGD Ex, but I'm not so sure Black's bishop belongs on f5.  Rather than dive in and grab a pawn in the opening, bringing the knight to f3 is what generally happens. 

I'm in a couple of groups here that play QGD, you should consider joining them and digging into both sides of this opening:

and

I hope the links work.

If you mean: "the move 2. ... e6 confines Black's Queen's Bishop", well yes, it does. But moving the Bishop out first would leave the light squares on the Queen's side weak, especially b7 and d5.

Black's usual object in the classical QGD is to first complete his development and castle, and THEN arrange to play either e5 or c5 to liberate his cramped game.

Be7 is probably preferable to Nf6 just to deny all this. White can still play the exchange, but the bishop must go to f4 instead and black's game is a little easier

Thanks very much for all the comments

Well, for what it's worth, if you look up the position after 8. Qb3 in the Game Explorer, there are two master level games and both are wins for white.
