Carlsen, who will be 23 years on 30th November, closed the championship with two games to spare by taking his tally to required 6.5 points out of a possible ten, winning three and drawing seven games.
In what could be marked as the dawn of a new era in the chess world, Carlsen showed stellar effort yet again by not going for a tame draw when one was enough for him to take the title home.
Instead, the Norwegian made Anand suffer for a long and gruelling four hours and forty five minutes before the Indian could heave a sigh of relief in what was the most one-sided world championship match in modern history.
Anand had won the world championship title five times 2000, 2007, 2008, 2010, 2012 -- but ironically was dethroned in his home town of Chennai.
In a dubious first, this was the only time that Anand failed to win a single game in a world championship match.
Starting with his journey in 1991, Anand had always scored at least one victory in each of the match that he played in the last 22 years.
Carlsen, was in his elements right through the tenth game getting what he wanted out of the opening and then pursuing on his favourite mission on grinding out opponent. Anand this time did not collapse and came up with some fantastic defense he is known for to steer the game to a draw.
Anand, on expected lines, employed the Sicilian defense and faced the Moscow variation that Carlsen had employed before.
There were no surprises earlier as both players opted for routine theory and it was a Maroczy bind structure on board after Carlsen came up with a check on move three, parting with his light squared Bishop for a knight.
On move 14, Carlsen took back Anand's light Bishop to even things up and it was again a slow grind thereafter that has been hallmark of Carlsen's play in this match.
With two minor pieces off the board, the position had only a minuscule advantage for white but Carlsen did not go for the draw. It was on the 21st move that many pundits believed both players will be happy to repeat moves.
Carlsen for obvious reasons and Anand because there was not much hope. However, the Norwegian was the first to deviate from a possible repetition.
Anand found some solace after trading another set of minor pieces but the pressure remained on the Indian. Carlsen went for his final liquidation plan on the 28th move when he pushed his king pawn to fifth rank. Anand temporarily parted with a pawn and recovered it some moves later but this led the game to a pure knight and pawns endgame.
To make matters worse for Anand, Carlsen retained his small advantage as his king quickly walked over to the king side and penetrated the fifth rank. Anand's knight and king were confined to the defense and to stop further damage. The players reached the first time control in just three hours when 40 moves were completed but by then it was also clear that either Carlsen will win or it will be a draw. In either case Anand's campaign was coming to an end and it was a pretty unpleasant task for the five times world champion.
As the game progressed both the players were engrossed in their own ways. Anand showed some signs of nervousness while Carlsen at one point leaned like 'the Crocodile' he wants to be if he was an animal. Relaxed but ready to eat the prey when they came its way.
The situation took another dramatic turn on the 46th move when Carlsen sank in to a long thought. The Norwegian looked at the possibilities of sacrificing his last remaining pieces and this is what he did a couple of moves later. In return, Anand lost all his pawns and the players promoted new queens on the board.
Anand had an extra Knight but Carlsen had Queen and a couple of dangerous looking pawns on the queen side.
Finding just the right moves, Anand forced an exchange pretty soon leading to a forced draw. The epic lasted 65 moves.
Apart from the winning the title, Carlsen will also take home 60 per cent of around Rs. 14 crore as part of his winner's purse.
Fifth game was the turning point, says Vishwanathan Anand
Admitting that newly-crowned world champion Magnus Carlsen dominated the duel, five-time title holder Vishwanathan Anand today said that the loss in the fifth game of the World Chess Championship match turned out to be a "heady blow" for him.
Anand's reign as the world champion came to a heart-breaking end today with Norway's Magnus Carlsen taking the crown after a hard-fought draw in the 10th game of the World Chess Championship match here.
Carlsen, who will be 23 years on 30th November, closed the championship with two games to spare by taking his tally to required 6.5 points out of a possible 10, winning three and drawing seven games.
"The fifth game was a heady blow. I had really hoped not to be afraid of him in the long games and simply to try and match him. It was not to be. After that it got worse and worse. Yesterday at least it was a nice game and today again...I guess when it rains it pours," a disappointed Anand said at the post-match press conference.
"Its clear that Magnus dominated. At the start of the match I thought my chances depended on my ability to last long games without making a mistake. This year I have had problems with mistakes creeping in to my play. I tried to pay some attention to that. But in the end it was in vain because the way I lost the fifth game is exactly I thought I could not afford to lose. A fine position in the opening and slowly slip and so on," he noted.
Anand might have lost his crown to someone 21 years junior to him but the Indian was a picture of composure while admitting that he committed mistakes today also.
"I think today I was just trying to keep playing and at some point started to make mistakes. I made a wrong queen move. I simply don't know the evaluation after the match, the knight ending is pretty dangerous," Anand said about the final game that ended in a draw.
Anand was gracious in his defeat and congratulated Carlsen for his splendid victory.
"Its enough to just congratulate him (Carlsen). My mistakes did not happen by themselves. Clearly he managed to provoke them and full credit to him," Anand said.
Asked about the third game where he had chances to go one up, the Indian ace said he did not attach much significance to it.
"Things look different with hindsight. At that moment I did not attach any excessive significance to it. Obviously I was disappointed I did not call the position right. It was a little bit disappointed then. With hindsight you can exaggerate anything. As far as I am concerned game five was when it started to go wrong," Anand elaborated.
Anand also said that he could not execute his plans in the match.
"I had a feeling this match will be about execution. Holding at the board and seeing it through was really what its about. Game five was the real low point for me. Till then nothing had really happened. I was simply not able to execute my strategy," he said.
Asked about his future plans and his comeback, Anand said he would think about it later.
"Well that's getting a bit ahead. I want to first get some rest and take stock of what has happened. Come to terms with everything here. At the end of the day my play in the match was a big disappointment. I didn't manage to any of the things I tried to aim for. I assume I will play the candidates (In March 2014 to qualify for next world championship match)," he said.
