ok, so i will do
i had also analysed 15.Qc5 and came to conclusion that Black should be ok, but 15.Qb2! looks more logical and the best place for the queen for the moment.
My mainline goes: 15.Qb2 Bg4 16.e3 Bxf3 17.gxf3 Rfd8 18.Be2 Rac8 (this rook moves develop black pieces but i'm not sure if black should ido something more concrete) 19.Rc1! (19.0-0 Nd4! and black can get away with a Q-R-R ending pawn down but good drawing chances) next move will be 0-0, it seemed to me that White is much better

Yes, we noticed this recent try and we covered it in the book. The analysis runs:

1. d4 d5 2. c4 e6 3. Nc3 c5 4. cxd5 exd5 5. Nf3 Nc6 6. dxc5 d4 7. Na4 Bxc5 8.Nxc5 Qa5+ 9. Qd2 Qxc5 10. a3 Nge7! 
This is the typical move for Black in this system. Now White can try to win a pawn but...
11. b4 Qb6 12. Bb2 O-O 13. Bxd4 
Of course no 13.Nxd4? Rd8 14.Rd1 Nf5
13...Nxd4 14. Qxd4 Nc6! 15. Qc5 Bg4 16. e3 Qxc5 17. bxc5 Bxf3 18. gxf3 Rac8 19. Rc1 Rc7
and Black is at least equal. If you have something to add here before the book go to the printer, please do!

As a Tarrasch player I consider the following line as the most anoying. Wondering how you people play this position.

1.d4 d5 2.c4 e6 3.Nc3 c5 4.Nf3 Nc6 5.cxd5 exd5 6.g3 Nf6 7.Bg2 Be7 8.0-0 0-0 9.Bg5 cxd4 (I now c4 is possible but as many others I like the tarrasch for the IQP) 10.Nxd4  h6 11.Be3 Re8 12.Rc1 Bf8 13.Qc2

I used to play Bg4 but after Rfd1 its quite difficult for black . Aargaad recomend Rc8 but after Qa4 the white advantage seems quite clear to me (a7 is week)

Keilhack mentions 13....Be6 but I am feel that after 14.Nxe6 fxe6 the week white squars around the Black King gives white again a clear advantage.

Right, best behaviour everyone, we appear to have a GM present amongst us.

PS to Smurfo: the still fairly rare line 4 cxd5 exd5 5 Nf3 Nc6 6 dxc5!? has been causing us some real headaches here, and I for one am not sure that we've really sorted it yet.

Thanks.  I'll pay, just let me know the terms.

Same for me.
Could you give the initial 8 moves in the line above? I kinda lost track.

In the process of the proff-reading, another viable method for Black was found.

After 9.Bd2 Qxc5 10.Rc1 Qb6 11.e3 Bg4!?
We analysed this continuation and no significant advantage for White was found! The main line runs:
12.Be2! Nge713.Nxd4 Bxe2 14.Nxe2 Qxb2 15.Qa4 0–0 16.Bc3 Qb6 17.0–0 Rad8 18.Rb1 Qc7 19.Rfc1 and now after 19...Rd7! Black slowly gets to an equal ending where has chances even for a win! (i mean that this ending is not "dead-equal")

The PC suggests (8...Rc8) 9.Na4 Ne4 10.a3 d4 11.Nxd4 Qa5+ 12.b4 Nxb4 13.Bd2 Nd3+ 14.exd3 Nxd2 15.Qxd2 Qxa4 16.Nxe6 Qc6 17.Ng5 Qxh1 18.Qf4 f6 19.Qe3+ Be7 20.Ne6, but Black may be able to hold: 20...b6 21.d4 bxc5 22.dxc5 Qd5 23.Rb1 Kf7 +=.
