1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... g8f6  4. e1g1  4... f6e4  5. d2d4  5... e4d6  6. b5a4 An  interesting side line. Nepomniachtchi does not shy away from sacrificing a pawn against anyone. 6... e5d4  7. c2c3  7... f8e7  8. c3d4  8... b7b5  9. a4b3  9... e8g8  10. b1c3  10... c8b7  11. f1e1  11... e7f6  12. c1f4  12... c6a5  13. b3c2  13... b5b4  14. c3a4 So far Black has played well; however, his next obvious move will be the main reason for his future problems. 14... g7g6  15. f3e5 White's knights will dominate from here on. 15... d6b5  16. a4c5  16... d7d6 Now a beautiful tempo fight starts. 17. c5b7  17... a5b7  18. e5c6  18... d8d7  19. c6b4 White regains the pawn for a moment. 19... b5d4  20. b4d5 And then the knight lands on another brilliant  position. 20... f6g7 However, now after 21. e1e7  21... d7d8  22. f4g5 Nepomniachtchi builds a nasty ambush, which  Radjabov cannot block at all. 22... g8h8 Now look what Nepomniachtchi  found: 23. c2g6  23... f7g6 Now what? The rook is not taking on g7 with check. 24. h2h4 This! A silent move, which creates violent threats. This  strength is what the world champion will be facing at the long-awaited  match. 24... d8e7 The only idea. Everything else would lose without a  chance. 25. d5e7  25... a8e8  26. g5e3 A pity. 26... c7c5  27. e7d5  27... e8e5 At last showing some activity. Radjabov has  significantly improved his chances. 28. d5c3  28... b7d8  29. d1d2 While Nepomniachtchi is moving in the wrong  direction. 29... d8e6  30. e3h6 After this trade, Black's position becomes  comfortable. 30... g7h6  31. d2h6  31... f8f4 Forcing a kingside weakening. 32. g2g3  32... f4f7  33. h6c1  33... e5f5  34. f2f4  34... h7h6  35. c1d1  35... g6g5 Radjabov is following his plan. 36. h4g5  36... h6g5  37. c3e4  37... f7h7  38. e4d6  38... f5f6  39. f4f5  39... f6h6  40. g1f2 Nepomniachtchi keeps playing for a win and slowly  crosses the red line. 40... h6h2 Now Radjabov misses a great idea. True, the unthinkable  coordination after 41. f2e3  41... d4c2  42. e3e4  42... e6d4  43. f5f6 The red line... 43... h2e2  44. e4d3  44... c2a1 Now Nepomniachtchi will get his advantage back.  45. d1a1  45... e2e6  46. d6e4  46... d4f5  47. a1c1  47... h7d7  48. d3c3  48... f5d6 That's the difference. 49. c1h1 Best play by  Nepomniachtchi once again. 49... h8g8  50. e4g5  50... e6f6  51. h1d5
