A horrible blunder. Just like yesterday, Ding's clock came down to seconds, and the  Chinese GM could not stand the pressure.
1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... f8g7 After praising his opponent for the  excellent positional play (against Nakamura a couple of days ago) Carlsen  decided to show who is the boss in the KID. 4. e2e4  4... d7d6  5. g1f3  5... e8g8  6. h2h3  6... e7e5  7. d4d5  7... b8a6  8. c1g5  8... c8d7  9. f3d2  9... c7c6  10. f1e2  10... d8b6  11. a1b1  11... g8h8 A novelty, a la Kasparov. Nf6-g8  followed by Bg7-h6 might happen some time in the future and of course, the f7-f5 breakthrough is never out of the question. 12. e1g1  12... c6c5  13. a2a3 A standard reaction. 13... b6d8  14. b2b4  14... b7b6  15. c3b5 There are many tempting possibilities  instead. 15... d8e7  16. f1e1  16... h7h6  17. g5h4  17... f8c8  18. e2d3  18... e7f8  19. d2f1  19... f6h5  20. f1e3  20... g7f6 It is Black who gets rid of his  weaker bishop first. But every King's Indian player knows that this is not the end of his problems. 21. h4f6  21... h5f6  22. b5c3  22... f8e7  23. d3c2 Back to the light-squared bishop swap  idea. 23... a6b8  24. d1d2 Change of heart. 24... h8g7  25. g1h2 A useful prophylaxis again and an inaccuracy... 25... c5b4  26. a3b4  26... a7a5 This is what Ding probably underestimated.  Carlsen builds up a wonderful dark-squared blockade on his weaker flank. 27. b1a1  27... b8a6 A wonderful positional decision! Obviously Carlsen planned this when he captured on b4. 28. b4a5  28... b6a5  29. a1a5  29... a6c5  30. e1a1  30... a8a5  31. a1a5  31... e7d8 It all make sense for Black now. The trade of the bishops, the  play where he is weaker; the super knight compensates him for that. 32. a5a3  32... c8b8  33. f2f3  33... f6h7 More effective than the obvious 34. c3e2  34... d8h4  35. a3a1  35... h7f6 The world champion misses a chance to win a pawn.  36. d2e1  36... h4g5  37. a1a3  37... f6h5  38. g2g3 Ding manages to cover the dark squares.  True, he is weakening the second rank and has to be careful for the  future. 38... g5d8  39. e1a1  39... h5f6  40. f3f4  40... d8e7  41. e2c3  41... g7h7  42. f4f5  42... h7g7  43. a3a7  43... g6g5 Gaining some room on the kingside. 44. h2g2  44... e7d8  45. g2f3  45... h6h5  46. a1c1  46... d8b6 Both sides continue the maneuvering  game. 47. a7a1  47... b8g8  48. c1d2  48... b6d8  49. a1g1  49... g8h8  50. h3h4  50... g5g4  51. f3e2  51... g7h7  52. g1b1  52... d8a5  53. e3d1  53... h8g8  54. d1f2  54... a5a6  55. c3b5 A risky decision. The knight is a very valuable piece. 55... g8b8  56. c2d3  56... d7b5  57. c4b5  57... a6a4 The active black pieces make his play much easier, and a  deja vu is about to happen. 58. d2b4  58... a4a2  59. b4b2  59... a2a4  60. b2b4  60... a4a2  61. b1b2  61... a2a1  62. b2b1  62... a1a7  63. b4d2  63... c5d3  64. d2d3  64... a7a2  65. e2f1  65... b8c8
