1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. f2f3 One of the most aggressive variations to face the Nimzo-Indian Defense. 4... c7c5 This is a very popular move these days, although there is nothing wrong with the old 5...d5 move. 5. d4d5  5... d7d6  6. e2e4  6... e8g8  7. c1f4 A strange new move, which immediately leads to trouble for White. It's hard to say why Nepomniachtchi chose it. 7... f8e8  8. d5e6 Another compromising move. 8... c8e6  9. f1d3 Taking the pawn on d6 doesn't help White either. 9... b8c6  10. g1e2  10... c6e5  11. b2b3  11... f6h5  12. f4g3  12... h5g3  13. h2g3  13... d8g5 Black could immediately play two ideas that will be shown later: put the queen on f6 or blow up the position with the b5 and d5 breaks. 14. d1d2  14... g5f6  15. a1c1  15... b7b5 It's necessary to destroy the white center to exploit the advantage in development. 16. c4b5  16... d6d5  17. e4d5  17... e5d3  18. d2d3  18... e6f5  19. d3d2  19... e8e5 A very accurate move. 20. e1g1  20... e5e2  21. d2e2  21... b4c3  22. c1c3 Otherwise, the bishop is brought to d4. 22... f6c3 Black has a decisive material advantage, and Radjabov doesn't give his opponent any chance of redemption. 23. f1d1  23... g8f8 With the idea of taking the rook to e8. 24. d5d6
