One interesting move not discussed in the book, that seems promising to me is after 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. Bd2 Qxc5
10. b4!?
I don't find this move in my database.
Here 10...Nxb4 seems highly dangerous to me so black should play 10...Qb6, but is under considerable pressure after 11.Qa4.
It has been played in some computer games. I think that we should have analysed it in the book. My analysis is this:
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. Bd2 Qxc5 10. b4 Nxb4
Only decent move and the only one played in those games
11. Rc1 Qd6 12. e3 dxe3 13. Bc3
(13. Bb5+ Nc614. Qe2 Nge7 15. Bxe3 Bg4 16. O-O O-O 17. h3 Bxf3 18. Qxf3 Rfd8 seems balanced. Black has an extra pawn to counter the pair of Bishops)
13... Nd5 14.Bb5+ Ke7!
This is the improvement over the only PC game reached this position
15. Bxg7 if not this then Black has no problems
15...Qb4+ 16. Kf1 Qxb5+ 17. Kg1 exf2+ 18. Kxf2 Ngf6 19. Bxh8 Ne4+20. Kg1 f6 21. Qd4 Bf5 22. Bg7 Rc8 and Black wins! So, Black doesn't have any problems what so ever in this line.
Thank you for bringing this to my attention!
