During the Chess World Cup 2007, which served as a qualification tournament for the World Chess Championship 2010, Karjakin reached the semi-finals, in which he lost to Alexei Shirov. On the January 2008 FIDE rating list, published just before Karjakin's 18th birthday, he passed the 2700 mark for the first time, often seen as the line that separates "elite" players from other grandmasters, with a new rating of 2732 and a world rank of 13.
