The intention is to avoid …Bg4 and the exchange on f3, which accentuates the weakness of the d4-square. 8... c6d4  9. c1e3  9... d4f3  10. d1f3  10... b6e3  11. f3e3  11... e8g8  12. g2g3 It's also possible to speed up development by placing the bishop on e2. The advantage of the move played in the game is that the bishop on g2 prevents the c6-d5 advance and supports the kingside advance with f2-f4. 12... c7c6  13. f1g2  13... d8b6  14. e3d2 More combative than allowing the exchange of queens. 14... a7a5  15. b4b5  15... c6b5  16. c3b5  16... c8d7  17. b5c3  17... d7c6  18. e1g1  18... f6d7  19. a1b1  19... b6c5  20. b1b3  20... f8e8  21. g1h2  21... d7f8  22. f2f4  22... f7f6  23. f4f5  23... f8d7  24. g3g4  24... a8a6 Preparing to take the rook to b6 and start the counterplay. 25. c3e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] 25... a6b6  26. b3b6  26... c5b6  27. h3h4  27... b6c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] A very cold-blooded plan. Nakamura correctly judges that White's attack is not decisive and that there's time to capture the pawn on a3 and return with the queen. It takes tremendous knowledge of chess to play like this. Most chess players would bring the queen to the defense immediately. 28. g4g5  28... c5a3  29. e2g3  29... a3b4
