1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... f8g7  4. e2e4  4... d7d6  5. h2h3  5... e8g8  6. g1e2  6... a7a6  7. e2g3  7... c7c6  8. f1d3 An obvious move, and a novelty. 8... b8d7 Next, both sides finish their development and initiate a  clash in the center. 9. e1g1  9... b7b5  10. c1e3  10... e7e5  11. d4d5  11... c6d5 Switching to Ruy  Lopez pawn structures. 12. c4d5  12... d7c5  13. d3c2 This is an excellent bishop. It prevents Black's  main kingside counterplay with f7-f5, restricts the black knight and is  ready to switch to the attack of the a6+b5 pawn complex (or whatever is  left of it). 13... f6e8  14. b2b4  14... c5d7  15. a2a4  15... b5a4 The only move. 16. c2a4  16... a8b8  17. b4b5  17... d7c5  18. b5a6 The total evaporation of the queenside is favorable for Black. 18... c8a6  19. f1e1  19... c5a4 A bishop is a bishop. 20. a1a4  20... a6c8  21. a4a7  21... f7f5 Now it is even easier to play as Black, and Radjabov starts his  programmed kingside assault. 22. e4f5  22... g6f5  23. g3h5  23... g7h8  24. d1f3  24... f5f4  25. e3d2  25... d8g5 Stepping into a pin. 26. h5g3 which Caruana uses to recentralize his knight. 26... g5g6  27. g3e4  27... e8g7 At the end of the day this knight still dreams  of the d4-spot. Radjabov's pieces are solidly entering the battle whereas  Caruana does not have a clear aim and simply tries to prevent too much  activity for now. 28. e1a1  28... h7h5  29. g1h2  29... g7f5  30. f3d3  30... h8g7  31. a1g1 Caruana decided to overprotect his  kingside and possibly try to open the g-file for his own benefit. 31... h5h4 Stopping g2-g3 once and for all, and fixing a square. 32. c3e2  32... b8b7  33. a7a8  33... b7f7  34. d2b4  34... g6h6 But in the process Black's position becomes even more interesting. Black is X-raying the opponent's king. 35. g1c1  35... c8d7  36. a8a6  36... f4f3 All black pieces come into play, and White's game hangs on  a very thin thread. 37. b4d2 In a moment of danger Caruana's pieces  hurry to each other's support. 37... h6h5
