Update: video added.
Viswanathan Anand has retained his world title by drawing Vladimir Kramnik in the 11th game of the World Championship match in Bonn, Germany. The final match score is 6?Ǭ?-4?Ǭ? for Anand.

It was a task he had never managed to do before: beating Viswanathan Anand with the black pieces. And after his opponent switched to his long-life weapon 1.e4, Vladimir Kramnik couldn't do it today either. At the press conference the Russian said it was a "difficult day" for him: "It was not easy to prepare for e4 and d4, trying to find forced wins for Black against all these moves."

He was reasonably satisfied with reaching the Najdorf, because "at least we had a game - it was not easy to just get a game". But he managed, although then Kramnik soon had to work on his own, because a few moves after Anand's 6.Bg5 he was out of theory - he actually found 9...Qc5 behind the board.

Black's seemingly anti-positional 12...exf5 was his only chance, Kramnik said, because "otherwise White simply gets very easy play"; he mentioned the standard moves Kb1 and g3 + Bh3, pressing on e6. "So I decided to mess things up." However, Anand reacted very well, calculated very well, and forced a liquidation to an ending that White simply cannot lose. "Miracles happen, but very rare, unfortunately," Kramnik finished his statement about the game.

After the game Anand said he was "happy, but at this point probably more relieved than happy. Obviously it's really nice to just have the title. Vlady was really pushing me in the last few games. With White I was really hoping to have the world championship title in the evening but I wasn't sure, you never know."

With this official and undisputed World Championship, Anand has won every big event that has been organized during his career. In fact, he's the first player to have won a world championship in three different formats. In the year 2000 Anand won the FIDE World Chess Championship which was a knockout event, in 2007 he won the World Chess Championship which was a tournament of six players, and now he has won a World Championship match. If he didn't yet belong to the list of great names starting with Steinitz, Lasker and Capablanca, he now sure does - nobody can deny it anymore. After all, today Anand has beaten the man who beat Kasparov.

Thanks to his 11 games in Bonn, Anand is also the new world's number one on the live rating list (for the top ten see the column on the far right) - he shares a virtual rating of 2791 with Topalov but tops the list because of actually having played games in this period.

Today Anand, who will turn 39 on December 11, won the most important prize of his career. It all started in 1983 when he won the National Sub-Junior Chess Championship with a score of 9/9. He subsequently became the youngest Indian to win the IM title at the age of fifteen, in 1984. One year later he became champion of India and in 1987 he became the first Indian to win the World Junior Chess Championship. In 1988, at the age of eighteen, he became India's first Grandmaster.

Ever since he won the super tournament of Reggio Emilia in 1991, ahead of Kasparov and Karpov, Anand has been among the world's elite. Among his colleagues he became known as the fastest player in the circuit and this was confirmed by him winning the unofficial world championship of rapid chess many times.

In the year 2000 Anand won the FIDE World Chess Championship in Tehran after defeating Alexei Shirov in the final. In the same year Garry Kasparov lost his world title to Vladimir Kramnik in London.

In 2002 Ruslan Ponomariov took over the title of FIDE World Champion and in 1995 Anand finished shared second with Peter Svidler at the San Luis World Championship tournament, behind Veselin Topalov. One year later Topalov lost his title against Kramnik, in a match that decided the first undisputed World Championship since 1993.

In September 2007 Anand became World Champion again by winning the FIDE World Championship Tournament held in Mexico City. He finished on 9 / 14 which was a full point ahead of Vladimir Kramnik and Boris Gelfand. Kramnik had agreed to participate in this tournament after FIDE had given him the right, if he wouldn't finish first, to automatically challenge the new World Champion.

This eventually resulted in the Anand-Kramnik match held in Bonn 14-29 October, that was dominated by the Indian from the start. After two reasonably quiet games he won twice with Black in games 3 and 5, and then scored another full point in game 6. In the final phase of the match Anand lost his concentration in a few games and even lost game 10, but by easily drawing the 11th game, he reached the unbeatable 6.5 points.

It was Anand's strategy with the Black pieces that decided the match. It's possible that the Indian didn't expect to achieve too much with the White pieces against one of the most solid players in the circuit, and therefore decided to focus the attention on Black. His choice of the sharp Meran positions was a brilliant one and with it he delivered the first major blow in game three. Again under pressure, Kramnik blundered in game 5 and this second blow led to the Russian playing his weakest game, number six, where he lost an ending that he would have drawn in most other situations.

Being 3 points down in a 12-game match is another way of saying: it's just hopeless. But it can only be admired how Kramnik managed to fight back in subsequent games - he finally started to feel confident, finally started to come up with theoretical novelties and simply... finally started to play on his normal level. But it was too late - Anand's narrow escape in game 9 earned him a valuable half point and then for Kramnik it was clearly a mission impossible to score 3 out of 3 against this kind of player.

Anand's victory was based on a combination of excellent preparation and playing almost flawlessly. A deserved champion who has deservedly entered the famous list of World Championship match winners.
