Here's a game I lost playing white with the Queen's gambit declined. I played pretty much book moves from the opening but still managed to get myself into a bad position from which my pieces became entangled and I my opponent slowly constricted me until I finally lost.

So, what's wrong with the Queen's gambit delined? (Or is it just me?)

 How should I have played the opening differently? (Maintaining the initiative while making solid developing moves)

(Apologies-I seem to have put it in as a puzzle)

I think it's just you, I love playing the QGD. 5.Bf4? I play 5.Bg5 here.

5.Bg5 0-0 6.e3
