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.
