But Nakamura  proves otherwise. 10. d4c5  10... d6c5  11. d1d8  11... f8d8  12. b1a3  12... f6e8  13. g2f1 Playing for the light squares is a very logical thing. 13... f7f6  14. f1c4  14... g8f8  15. c1e3  15... b7b6  16. c4d5 The hole on d5 starts to tell, but Black stays cool. 16... c8d7  17. a3b5  17... a8b8  18. a2a4  18... a7a6  19. b5a3  19... c6e7 Covering the central square. 20. d5b3  20... e7c6  Otherwise a4-a5 will follow. 21. f3d2  21... e8c7  22. f2f4 It is getting very tense in the middle of the board. 22... g7h6 But Nakamura is ready to strike back as usual. 23. g1g2  23... c6a5  24. b3c2  24... d7c6  25. b2b4  25... a5b7  26. d2c4 A wrong step. 26... e5f4  27. g3f4  27... b6b5 Now Nakamura takes over the initiative. 28. a4b5
