Giri, Carlsen and Mamedyarov remain in the Tata Steel Masters lead after 11 rounds - 11

The 80th Tata Steel Masters returned to Wijk aan Zee for the 11th round. The leaders Shakhriyar Mamedyarov and Magnus Carlsen drew a fairly dull game where the World Champion got easy equality with black but nothing more. Anish Giri was under some pressure from Fabiano Caruana's London System but if there was any advantage for white it had gone by first time control.

Viswanathan Anand ground down Hou Yifan to move within half a point of the leaders. Maybe Hou Yifan should have held a rather miserable major piece endgame but it was not easy at all. Sergey Karjakin won his second game of the event in a long technical endgame against Vladimir Kramnik. Wesley So won an exchange for a pawn against Gawain Jones and eventually converted the advantage. Matlakov-Svidler and Adhiban-Wei Yi were fairly dull draws.

Santosh Vidit and Anton Korobov both drew again and retain a joint lead on 7.5pts.
