16. Nxh6+!!
White sacrifices a knight to storm the kingside. This excellent move was prepared by Sergey Karjakin and his team (GM Alexander Motylev and others) at home. It is interesting that Peter Leko after his game in this round said he prepared this move too, with the Hungarian team three years ago.
