1. e2e4  1... c7c5 In a must-win situation, Ding naturally switches to the Sicilian defense. 2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... b8c6  6. f1e2 The most  solid, classical choice. 6... e7e5  7. d4b3  7... f8e7  8. c1g5  8... e8g8  9. g5f6  9... e7f6  10. c3d5 This position was always considered either slightly better for White (from the perspective of the first player) or absolutely harmless (from  Black's perspective.) Both evaluations suited Radjabov well. 10... f6g5  11. e2g4 Trading the light-squared bishop is a dream-come-true for White  if the pawn structure does not change. 11... c8e6  12. e1g1  12... g7g6  13. g4e6  13... f7e6 Ok, now Black can also be happy as  he managed to cover the vulnerable f5 and d5 squares. 14. d5c3  14... d8e7  15. d1d3 White's play is relatively simple, whereas Black needs to prove  kingside initiative to stay in the match. 15... a8d8  16. a1d1  16... a7a6  17. a2a3  17... g8g7  18. d3g3  18... h7h5  19. c3e2  19... d6d5 Ding needs to play energetically. 20. g3c3 On  his turn Radjabov tries to provoke d5-d4 to ossify the pawn structure.  Then the knights will be celebrities. 20... f8f6  21. c3c5  21... e7f7  22. c2c3 Yes, seconds on the clock does not help determine  all the subtleties of a position. A seemingly solid-looking move turns out to have a serious tactical flaw. 22... h5h4 Ding plays on the side where he is better by default. 23. h2h3  23... d8d7  24. c5b6 Now everything is under control for Radjabov. His pieces are  optimally placed and the black bishop-somewhat empty. 24... d7e7  25. b3c5  25... g7h7 Preparing kingside attack. 26. b2b4 This is where White should  play. If he removes the black knight from its optimal position on c6  Ding's position is going to collapse. 26... d5d4  27. c5d3 Solid and good. 27... e7d7  28. b6c5  28... d4c3  29. c5c3
