Probably missed by Aronian.
1. d2d4  1... g8f6  2. g1f3  2... g7g6  3. b1c3  3... d7d5  4. c1f4  4... f8g7  5. c3b5  5... b8a6 This position can  occur with reversed colors from the Chigorin Defense. 6. e2e3  6... f6h5  7. f4g5  7... c7c6  8. b5c3  8... d8b6 A novelty, but a typical move for the position. Black forces a concession. 9. a1b1  9... f7f6  10. g5h4  10... e8g8  11. h2h3  11... e7e5 All of this is pretty logical, but  Aronian's last move is not optimal. 12. g2g4  12... g6g5  13. g4h5  13... g5h4  14. h1g1  14... g8h8  15. h5h6 That is the difference: the h5-square is available for the queen, and Le can start attacking the  opponent's king at once. 15... g7h6  16. f3h4  16... h6g5  17. d1h5  17... g5h4 Sad, but needed. Otherwise, Nh4-g6 is unstoppable. 18. h5h6 A smart intermediate  move. 18... f8f7  19. h6h4  19... a6b4  20. e1d2  20... c6c5 Aronian blunders. 21. a2a3  21... b4c6
