It's not so bad. But it's not clear to me that this is an anti-Nimzo, since black will often not even play d5 in a Nimzo. I saw a3 done by Capablanca and annotated "white prevents the Cambridge Springs at the cost of a tempo" - it surely results in an even game.
Queen's Gambit Declined: Anti-Nimzo

For me it's in the same category as Bd2 against the real Nimzo-Indian. It doesn't get any advantage, but it's ok. It's not like you're playing 3.a4 against the QGD, which may in fact be a liability. (As long as black doesn't rotely play the systems which strive for b5 LOL)

Bd2 in this line: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bd2
About your b3 comment: LOL it almost sounds like white's position is crumbling!
FWIW: I play 1.a3 myself, and have even done so otb in the World Open, and have punted 3.a3 as well, so I am speaking from experience.....it is not good. If you want to win as White there are many better choices.
Could you offer an alternative then. The reason I play a3 is I have trouble against transpositions to the Nimzo-Indian and against Bb4 in general. I am obviously not playing at a high enough level for the weakness of the move a3 to be noticable yet. I currently don't play anyone above a USCF 1800 and on average I only play around 1200s this may be why I have been able to play with moderate success.

1.d4 d5 2.c4 e6 3.cxd5 exd5 4.Nc3 and you don't have to deal with dxc4 by black.
Harpo I am stalking every thread you post in. :-)

Exchanging on move 3 is a slight inaccuracy because then Black plays 4. ...c6! instead of Nf6 and gets a good exchange Slav..... very annoying for the prospective QGD Exchange player.
How does that help black? The only thing I can think of is that delaying Nf6 doesn't let white play Bg5. But what does black play after
1.d4 d5 2.c4 e6 3.cxd5 exd5 4.Nc3 c6 5.Nf3
Is the idea to prevent white from playing the Nge2 system, thus taking away some of the flexibility of the QGD exchange?
Perhaps I am completely missing the point?

Ah I see I will have to look for this game. If Capablanca played it it can't be bad. Thank you.
I located the game. It's game #5 from the 1927 world championship match between Capa and Alekhine. Capa played white.

Unfortunately not many people play the QGD in the manner anymore - at least I don't encounter it too often. I'm better served studying other things, such as middlegame strategy in a variety of position types.
I'd be interested in a rematch also, but not yet, since for some reason I've agreed to too many team matches. They're a bit lighter on the commitment compared with tournaments though so they should be over quicker.

I saw the Grunfeld from MirceaH and he wiped me with it. I agree though, I like to play the white side of it. You get a VERY comfortable position, winning even, until you lose.
This is an opening line of my own creation. I play it to avoid the Nimzo Indian. This is an opening line I've been looking at alot lately. It only has 160 games in the master db here. It also seems to score very low. This also bothers me. I think this is most unfortunate as I have been playing this line with great success OtB. I was wondering if anyone could explain why it isn't played. If you think you find a refutation for it I'd be glad to play you. I need to practice this line anyway. Thus without further ado, my Queen's Gambit Declined: Anti-Nimzo.

I would be inclined to call it the Queen's Gambit Declined, Anti-Ragozin Variation.
