Khanty Mansiysk (Russia): Five-time world champion Viswanathan Anand remained in sole lead with a third straight draw, signing peace with Russian Sergey Karjakin in the sixth round of Candidates Chess tournament here today.

After scoring two victories in the first three rounds itself, Anand did not get many chances for the third day running even as Karjakin had to work hard for the half point. It turned out to be another high-tension round in the candidates that will select the challenger to Magnus Carlsen of Norway in the next World championship match later this year.
