11. c4 This continuation already met on tournament Moscow open 2009, successfully for White. [Not long ago 11. c3 O-O 12. Nc2 Bg5 13. a4 ba 14. Ra4 was popular.] White aspire to cause b5-b4, that will lead to stabilization on queen side and will strengthen White control white over d5. 11... b4 12. Nc2

[Usually White had queen rook on d1, leaving another one on f1 for "imitation" of possibility f2-f4 advancement. Asrian – Ni Hua (Taivan, 2006) Black had a good position after 16. Rad1 Bd5 17. cd Nb8 18. Bg4 Na6 and Nc5.]
16... Bd5 There is no need to hurry up with an exchange of Nd5, having made, for example, a useful move 16...Rb8. Further they are planning to prepare Nc6-e7 with an exchange of Nd5, but already with preservation an important Bishop. 17. cd Nb8

18. Ne3 Nd7 19. Rac1 Nc5

20. Rc5! The only move to struggle for initiative. 20... Be3 Разумеется, черные не хотят допускать после 20...dc 21.Nc4 сохранения у белых мощного блокадного коня при своем беспомощном чернопольном слоне. 21. Qe3! Блестяще! Белые готовы пойти на позицию без качества даже тогда, когда у них отсутствует конь, а у черных "плохой" слон! 21... dc

22. d6! After 22.Q:c5 Rc8 Black could had time to block a white pawn on d5. Now the white pawn is ready to slip to d7, that will decrease efficiency of black Rooks and activate a white Bishop. 22... Qb6 23. Bc4 Preparing Qd3 and Bb5. 23... Rad8 24. Qd3 Immediate 24.d7 with the subsequent Qd3 also was possible. That could led to a position, similar happened in the game, but eliminated additional possibility for Black on the following move. 24... Kh8
[After 24... Rd7 White would have had to support pd6: 25. f4 (25. Bb5 c4 26. Qd5 Rd6) 25... ef 26. e5]

25. h4 White starts to loosen King side of the opponent. 25... Rd7 26. Bb5 c4 27. Qd5 Rdd8 The capture of pd6 is impossible now because of R on f8. 28. Qe5 c3 29. bc f6
