Examples of recent early opening novelties at the top level The world elite usually practises extremely deep opening preparation based on established theory, with the first move that has never been played before often coming after the 20th turn.

What are some recent (last 20 years) examples of top-class players deviating from theory early (say, on the 8th move or before)?
Aronian vs Anand at Candidates 2014 (http://www.chessgames.com/perl/chessgame?gid=1751406) was out of theory after Black's 3rd move, but only because White played an extremely odd opening which will probably never be repeated at the top level.

Aronian vs Leko at Morelia-Linares 2008 (http://www.chessgames.com/perl/chessgame?gid=1486033) featured a strong novelty on White's 9th move.
