1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5 The Rossolimo seems a good choice against  Radjabov's Sveshnikov/Kalashnikov multi-year experience. An interesting  fact is that Radjabov faced the Rossolimo in almost half of the games in  which he went for 2...Nc6. Thus, where is the advantage in the main lines?  3... g7g6  4. e1g1  4... f8g7  5. c2c3  5... g8f6  6. f1e1  6... e8g8  7. d2d4  7... d7d5  8. e4e5  8... f6e4  9. b5c6  9... b7c6  10. c1e3 This is White's major attempt  these days. It slowly outshines the older 10.Nbd2. 10... c5d4  11. c3d4  11... d8b6  12. d1c1 The point behind White's play. He wants to stabilize the situation in the center, fix the c6-pawn and turn it into permanent weakness. The a-pawn might also be problematic for Black in the  future. 12... a7a5  13. b1c3  13... e4c3  14. c1c3  14... c8f5 Deviating from his game  against Grischuk. 15. b2b3  15... f8b8  16. f3d2  16... h7h5 A novelty. 17. h2h3 The opening outcome is pleasant for White. The bishop pair is not  much of an advantage here for Black as he cannot easily break open the  position. As long as So keeps everything under control on the c5- and  e5-squares, he can slowly squeeze his opponent, which is especially  unpleasant in rapid games. 17... b8c8  18. a1c1  18... g7f8  19. a2a3  19... a8b8 An obvious move that, however, does not build  enough queenside pressure. 20. c3b2  20... b6d8  21. c1c3 White's plan is simple and effective. Attack the weak queenside pawns with everything that you can. If a chance occurs, swap off the dark-squared bishops, and this would already be a strategically won  position for White. 21... d8d7  22. e1c1  22... f7f6 After this move, the dark squares get severely weakened. 23. c3c5 As usual, So is neatly following his plan. 23... b8b5  24. a3a4  24... b5c5  25. c1c5 With the trade of a rook pair, the  weaknesses on the queenside are clearly exposed. Radjabov lost the  strategical battle, therefore he decides to launch complications with... 25... f5h3  26. g2h3  26... d7h3  27. d2f1  27... f6e5  28. d4e5  28... f8g7  29. b2d4  29... h3e6  30. c5a5  30... g7e5  31. d4h4 There are enough defenders around the  white king, and the a-passer is ready to move. The compensation is clearly insufficient. 31... c8f8  32. a5a7  32... e5d6  33. b3b4  33... f8f3  34. a7a8  34... g8f7  35. e3h6 Again, very neat. So trades the active black rook. 35... e6e2  36. a8f8  36... f7e6  37. f8f3  37... e2f3  38. h6e3  38... e6d7  39. a4a5  39... d7c8  40. e3c5  Forcing another concession by Black. 40... d6f4  41. h4e7  41... f3g4  42. f1g3  42... f4g3  43. f2g3  43... g4g3  44. g1f1 So correctly calculated that the checks cannot last forever. 44... g3d3  45. f1f2  45... d3d2  46. f2f3  46... d2d1  47. f3f4  47... d1g4  48. f4e5 This required precise calculation, but So has  seen everything. 48... g4e4  49. e5f6  49... e4e7  50. f6e7  50... h5h4  51. e7d6  51... h4h3  52. c5g1  52... d5d4  53. d6c6  53... d4d3  54. a5a6  54... c8b8  55. b4b5
