Nakamura Leads Tata Steel - Again!
Hikaru Nakamura surged to the top of the standings yet again in Tata Steel after beating Ian Nepomniachtchi with the black pieces in round eleven.
Anand is half a point behind the American after drawing with Vachier-Lagrave, while Lev Aronian is another half point back in third place.
The only other winner in the A Group was Magnus Carlsen, who achieved the rare feat of beating Vladimir Kramnik with the black pieces in a complex endgame to draw level with him in a share for 4/5th place.
Nakamura ensures he is well hydrated before crushing Nepomniachtchi
Anand's choice of beverage is unclear as he is held to a draw by Vachier-Lagrave
Kramnik's choice of vodka 'a mistake' as Carlsen inflicts his first defeat of the tournament 
In Group B David Navara and Luke Mcshane won their games to join the pre-round leaders Wesley So and Zahar Efimenko on a score of 7/11.
Luke 'Tommy Cooper' McShane beats Ganguly, just like that, to re-join the leaders in Group B
In Group C Daniele Vocaturo virtually ensured victory by defeating his closest rival Kateryna Lahno to lead by 1.5 points with just 2 rounds left to play.
