Sochi: Viswanathan Anand failed to capitalise on an optical blunder by Magnus Carlsen and went on to lose the sixth game of the World Chess Championship, here on Saturday.(Highlights)
Carlsen, thanks to the lucky victory, surged ahead in the match for the second time and now leads the latch by 3.5-2.5 at exactly the half way stage with six games still remaining.
At the same point last year. The Norwegian had taken a two points lead at this point in the match and it was all effectively over for Anand.
