Check the game of Luc Winants. 3...Nc6 looks fine.

I have recently tried the following line with black (i've got it from an old CBM article):
1.d4 d5 2.Bf4 c5 3.c3 Nc6 4.e3 Qb6 5.Qb3 c4 6.Qc2
now ...Bf5 like in the 2.Nf3 Nf6 Variation is not possible because White can take the Bishop. However there is the move
6...e5!? 7.dxe5 Bf5 (now it works) 8.Qc1 g5! (8...Ne7!? is also interesting)
If white takes on g5 then Nxe5 gives Black great compensation and 9.Bg3 h5 10.h3 Bg7 11.Nf3 g4 12.Nd4 Ne7 13.Nd2 Nxe5  looks already a little better for Black.
Any suggestions where white can improve?
Interesting is the gambit 1.d4 d5 2.Bf4 c5 3.e4!?, but this may not be everyones cup of tea and objectively black should be fine here too.

Yelena Dembo in her "Fighting The Anti-King's Indians" recommends this setup:
1. d4 Nf6 2. Nf3 g6 3. Bf4 Bg7 4. e3 d6 5. h3 O-O 6. Be2 c5 7. O-O Qb6
I regard it as a decent approach to achieve something with black against London System. Additionally, I can point at the most critical game in this variation - Denis Khismatullin - Emil Sutovsky, 1/2-1/2 Moscow 2008 which continues like this: 8. Nbd2 Be6 9. Ng5 Bd7 10. Nc4 Qc7 11. c3 h6 12. Nf3 Be6 13. Rc1 Nbd7 with = ... The reason I give this game is that I think both players played the best moves.

Ditto. I'm surprised that these repetitive inane questions continue to generate responses from seasoned forum posters, who by now should know better.

Then again I just posted here so I'm just as guilty.

Responses to D-Pawn sidelines should be closely linked to the type of positions you play against the Queen's Gambit, where ever and when ever possible. Learn refutations where they exists and when forced out of your known patterns of play, resort to sound opening principles to find reasonable moves. For example, if you never saw or came across the following sequence before as black, how would you follow up and why:

1.d4 d5  2.e4 dxe4 3.Nc3 Nf6 4.f3

I thought this line was very good for White, based on an old SOS game of the month article on the NIC website.

A subscription to Eric's section answers all such questions!

When white plays a timid set-up, I generally find that an equal, playable middle game is often beyond their abilities too.

There are of course exceptions, but for me the way forward is to reach a comfortable position as Black and then outplay my opponent. Attempts to blow white out of the water are misplaced. White's position isn't bankrupt. White has simply given up on the advantage of the first move.

After the opening, just play chess and you should win.
