He immediately rushes with his knight  toward the weakened d6-outpost. 14... d8e7 Giri played this after some  thought. What happens next looks like the neatest way to deal with the  knight. 15. c3e4  15... e8c8  16. e4d6  16... d8d6 That was the point. 17. e5d6  17... e7d6 That's one of the main reasons why people accept the  gambited pawns early in the opening.
