A very creative idea by Aronian. 16. g4h5  16... b7b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] 17. h5h6 [%c_effect h6;square;h6;type;Inaccuracy;persistent;true] 17... b5b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] Now the knight has to go back. 18. c3d1  18... g7g6  19. g2f3  19... g8h7  20. d1f2  20... f6h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] An excellent pawn sacrifice.
