Anand seized the advantage in the middle of the 51-move game, sending his queen over to Carlsen's side of the board. But the Norwegian countered successfully and the two eventually agreed to draw.
"I missed some simple things in the middle game," Carlsen admitted in the post-match press conference. "It was not a disaster but it was scary."
The two players are fighting for the championship over 12 games. If they have equal points after the last game on November 26th, the match will be decided by a sudden-death game on November 28th.
Anand, 43, has been the game's undisputed champion since 2007, but Carlsen, 21 years younger, is seen as the favourite in what some experts have described as the most important chess game in two decades.
The total prize fund for the title clash is approximately $2.24 million, with the winner getting 60 percent and the loser taking home the rest.
