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  30. d2e2  30... b4b6  31. g3h5  31... b6d8 It transpires that White has no clear way to increase the attack and now Black is a pawn up and it's a passed one. 32. f1g1  32... g8h8  33. g2f3  33... e8g8  34. e2d2  34... a5a4  35. f3d1  35... d8e7  36. d2a5 Trying to recover the pawn on a4, but now it's Black who starts the attack on the kingside. 36... g7g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] 37. f5g6  37... h7g6  38. h5g3  38... f6g5  39. h4h5  39... g5g4 A smart move, paving the way for the queen. 40. h2g2 [%c_effect g2;square;g2;type;Inaccuracy;persistent;true] 40... g6h5  41. g3h5  41... g8g6 [%c_effect g6;square;g6;type;Mistake;persistent;true] This move allows White to recover the pawn. 42. h5g3 [%c_effect g3;square;g3;type;Mistake;persistent;true] 42... e7f8  43. g1h1  43... h8g8  44. h1h5  44... d7c5  45. h5f5  45... f8e7 Black has stabilized the position and has two more pawns, with a decisive advantage. 46. d1e2  46... c5e6  47. g2f2  47... e6d4  48. f5h5  48... c6d7  49. e2d1  49... g8g7  50. f2g2  50... g7g8 [%c_effect g8;square;g8;type;Mistake;persistent;true] Both players were in severe time trouble and Nakamura hesitated. 51. d1a4  51... e7f8  52. a4d1 [%c_effect d1;square;d1;type;Mistake;persistent;true] 52... d4e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] The knight heads to f4 and Nakamura is winning again. 53. g2g1  53... e6f4  54. h5h2  54... f4h3
