Round Ten At Tata
Hikaru Nakamura and Vishy Anand both won their games in round 10 of the Tata Steel tournament to emerge as joint leaders once again, with just three rounds remaining.
Anand crushed poor Shirov in just 26 moves, while Nakamura beat Vachier-Lagrave to leave them both on a score of 7/10.
Kramnik and Aronian dropped half a point back after drawing with black against Smeets and Giri respectively.
There was plenty more blood spilt, with Ponomariov beating Grischuk, and Wang Hao beating L'Ami in encounters from the bottom half of the standings.
Finally, Magnus Carlsen came unstuck against Nepomniachtchi. After declining a repetition draw, the Norwegian's position worsened significantly and he lost the game to drop to 5th place and possibly out of contention for the inaugural Tata Steel title.
"What have I done NOW?!" Shirov's run of poor form continues against Anand
Nakamura casually removes one of Carlsen's pieces while no-one is looking... 
"What am I gonna write in my blog about this?" Carlsen has another testing day...
Group B continued to produce great excitement and decisive games, with two of the pre-round leaders - McShane and Sargassian - losing to Efimenko and Quang Liem respectively. Efimenko's victory leaves him level with Wesley So at the top on a score of 6.5/10.
"There was a flash of light and that's the last thing I remember" McShane suffers his second loss
Quang Liem beats Sargassian in round 10 (all pics from the official Facebook page)
In Group C runaway leader Daniele Vocaturo lost against Ivan Ivanisevic but still leads by a full point from his nearest challenger, Kateryna Lahno.
Tomorrow (Thursday) is the final rest day. Round 11 is on Friday, followed by round 12 on Saturday, and the final round on Sunday. The Group A pairings for the final rounds can be found here.
