That's what everyone always says when they lose. Smiley

In the game Wang Yue-Mamedyarov, Baku GP 2008, Black improved with 13...Qb6, iirc. There White still retained a slight edge, but accurate play by Mamedyarov neutralised White's small advantage.

Perhaps 8.a4!? deserves more practical tests?
  

Nothing has meaning or value other than the meaning and value that you give it.

I think I will play,

8.Bg5 cxb5
9.e3 Bb7
10. f3

followed by Bd3 and Ne2 and b4
I like this position for white.

But ...
on my database search I read that instead of 10. f3, Nf3 should be better, but I don't really like it, I think black can equalise more easily.

I wouldn't know how black can equalise there. The simple development with 10.Nf3 is very strong and I think white is better in most variations. David Vigorito has some good discussion on the topic in his Callenging the Nimzo-Indian book, where he analyzes  the game Xu Jun - Wang Rui (see below). He has one subline with an early h6+g5 for black, where he thinks black might be fine, but I believe that due to the shakiness of black's kingside white is pretty much winning there, too, and my analyses back that up and I'm just waiting for the someone to play b5 against me. If you play Qc2 as white, then that book is well worth getting.

What to play against b5-Gambit in Qc2 Nimzo

Yesterday I lost a game due to lack in opening knowledge,

after 
1.d4 Nf6
2.c4 e6
3.Nc3 Bb4
4.Qc2 0-0
5.a3 Bxc3
6.Qxc3 b5

I played 
7.cxb5 c6
which is still o.k.

but now I played
8. bxc and soon got into a worse position,
and lost the game in ending one pawn down ...

On top level, noone accepts the gambit,
so ... I think I will play,

8.Bg5 cxb5
9.e3 Bb7
10. f3

followed by Bd3 and Ne2 and b4
I like this position for white.

But ...
on my database search I read that instead of 10. f3, Nf3 should be better, but I don't really like it, I think black can equalise more easily.
And I found a game with 8. Qd3 by Kasimdshanov, he says his novelty is the demise of the b5-variation in the Nimzo ...  but I think black can equalise also more easily ...
