However, Radjabov has something on his mind. 8... d7d5  9. e4d5  9... f6d5  10. f3e5  10... c6e5  11. e1e5  11... c7c6  12. d2d3  12... e7d6  13. e5e1  13... c8f5  14. d1f3  14... d8h4  15. g2g3  15... h4h3  16. c1e3  16... f5d3  17. b1d2  17... h3f5  18. e3d4  18... f8d8  19. a2a4  19... h7h6  20. h2h4  20... a8c8 [#] 21. f3f5 This is the Azeri's prepared novelty. He revealed that he almost did not prepare for this game as he had it all stored in his file. The  preparation was more psychological, as we shall see in a moment. 21... d3f5  22. d2e4  22... d6f8 Played after 30 minutes of thought!

A shocking central blow, against which Ding has to find  only moves. 26... f5e6 Everything else is inferior. 27. e5e6  27... f7e6  28. b3e6  28... g8h7  29. e6c8  29... d8c8 One more good sign for  Radjabov, who was up to here still in his prep! 30. c3b4  30... c8c4  31. d4f6 One more brilliant practical decision. 31... f8g7  32. f6e7  32... c4c6 Once again Ding hesitates and is uncertain which endgame to  chose. 33. a1a2  33... h7g8  34. e7c5  34... g8f7  35. g1g2
