1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c2c4  3... e7e6 Nakamura's super-solid symmetrical strategy  as Black is no surprise for anyone. 4. b1c3  4... f8e7  5. c1g5  5... h7h6  6. g5f6  6... e7f6  7. e2e3  7... e8g8  8. a1c1  8... c7c6  9. h2h4 A move once tried by Aronian against Carlsen. 9... g7g6  10. h4h5 Le needs to win the second mini-match to make it to the  blitz games and apparently spent a good amount of time preparing this  super-sharp line. With his last move he opens up the b1-h7 diagonal. 10... g6g5  11. f1d3  11... b8d7  12. d3b1 and quickly builds an attacking battery. 12... f6g7  13. c4d5 And that is a novelty. 13... c6d5  14. d1d3  14... f8e8  15. c3b5 An important move in Le's strategy. The inclusion  of this knight helps the kingside attack because the knight moves rapidly, thanks to the fork threats. 15... e8e7  16. f3g5 The point behind White's attack. The modest h-pawn joins the  battle, and the rook behind it is peeking at the black king. 16... h6g5  17. h5h6 This pawn causes havoc in Black's camp. 17... g7f6  18. d3h7  18... g8f8  19. h1h5 There comes the rook too. The pawn had opened its road towards  the king's residency. 19... d8a5 Nakamura does not miss his chance. 20. c1c3 But Le is as cold as ice! A knight is not as important as a tempo!
