8... Bb4 9. Nd2 Nb6 10. a5 Nbd5 

11. Nxd5? The correct move is 11. Nxc4! Bxc3 (Not 11... Nxc3? because with the exchange sacrifice, white will have a strong control over black dark square diaganol a3-f8 and also black`s knight is aiming on d6 square. 12. bxc3 Bxc3 13. Ba3 Bxa1 14. Qxa1) 12. bxc3 Nxc3 13. Qe1 Qxd4 14. Nd6+ Qxd6 15. Qxc3
 Threatening 16.Ba3! and black will have a hard time to castle and once against the idea of controling black`s dark square will give white the upper hand.
11... exd5 Of course 11... cxd5?? lost a pice after 12. Qa4+ Qd7 13. Qxb4

14. Rac1 Re8 15. Rfe1 Qd7 16. Qb4 b5 17. axb6 axb6 18. Bf4 Of course 18. Qxb6?? Reb8  And the queen is trap. 
18... Ra6 19. f3 Bh3  20. Bh1?! 

White's bishop is passive as it become clear a few move later. Better is to exchange it with 20...Bxh3 or let black exchange it 20...  Nh5 21. Be5 ? 21. Bd2 is better  
21... f6  22. Bd6  Re6 23. Bf4 Nxf4 24. gxf4 White`s kingside pawn has been destroy and his bishop on h1 is passive.
24... Qe8  24... f5! with idea of Qd8-Qh4-Rg6 is stronger. 25. Bg2?? Rg6 
25. e4 f5  25... Qg6+! 26. Kf2 Qh5 27. Rg1 Qh4+ 28. Rg3 Qxf4 
26. exd5 Re2 also strong is 26... Rxe1+ Black would have gained the upper hand for e.g 27. Rxe1 (The outcome after 27. Qxe1 Is more or less like the main line 27...Qxe1+ 28. Rxe1 cxd5 29. Kf2 Ra2 30. Kg3 Rxb2 31. Kxh3 c3) 27... Ra1 28. Kf2 (28. Rxa1 Qe3#) 28... Rxe1 29. Qxe1 Qxe1+ 30. Kxe1 cxd5

27. Rxe2  Qxe2 black threaten mate with Qe3++

28. Qe1??  A positional blunder. 28. Qc3! is correct and white probably can hold although not many people want to play his position.28...cxd5 29. Re1 Qd3 30.Kf2!?
28... Qxe1+ 29. Rxe1 cxd5 30. Kf2 Although white  win black`s bishop on h3 it cost him a lot of tempo and black`s use it to mobilise his pawns majority on the queen side.
30...Ra2 31. Kg3 31. Rb1 c3 32. Kg3 Rxb2 33. Rc1 winning for black
31... Rxb2 32. Kxh3 Black doesn`t mind giving his bishop because he had two powerful connecred passed pawn on the queen side.
32...b5 33. Bg2  It`s just to late to mobilize this lazy bishop.
33...b4 34. Bf1 34. Re8+  doesn't get the cat off the tree 34...Kf7 35. Re5 b3 36. Rxf5+ Ke6 37. Re5+ Kd6 is winning for black because of his strong passed pawn on the queen side.
