The '''World Chess Championship 2007''' was held in [[Mexico City]], from 12 September 2007 to 30 September 2007 to decide the world champion of the game of [[chess]]. It was an eight-player, double [[round robin tournament]].

[[Viswanathan Anand]] won the tournament and the title of [[World Chess Championship|World Chess Champion]]. His winning score was 9 points out of 14, with a total of four wins and 10 draws, and Anand was the only undefeated player in the tournament.

==Background==
This championship was unusual in that the [[World Chess Championship]] was decided by a tournament rather than a match.

The [[FIDE World Chess Championship 2005]] was also a double round robin tournament, but at the time the world title was split, with that tournament being for the [[FIDE]] world championship, and with Classical World Champion [[Vladimir Kramnik]] refusing to take part.<ref>[http://www.chesscenter.com/twic/kramfide.html Official Statement by Vladimir Kramnik], [[The Week in Chess]], 28 April 2005</ref> Soon after the 2005 tournament, FIDE announced that the 2007 World Championship would also be a double round robin tournament.

In <!-- May? --> 2006, FIDE announced the [[World Chess Championship 2006]], to reunify the world chess championship. Because the organization of the 2007 tournament was largely in place, conditions of that match included:
* If Classical champion (Kramnik) defeated FIDE Champion [[Veselin Topalov]], Kramnik would take Topalov's place in the 2007 tournament.
* The 2007 tournament would be a world championship.

Kramnik won the 2006 match. In June 2007, Kramnik confirmed that he recognized the 2007 tournament as the world championship, while expressing a personal preference for the championship to be decided by a match.<ref>[http://www.chessbase.com/newsdetail.asp?newsid=3899 Vladimir Kramnik on the world of chess (Part 2)], [[Chessbase]], 1 June 2007</ref>

FIDE later announced that future world championships (beginning with the [[World Chess Championship 2008]]) would be decided by matches between the champion and a challenger.<ref>[http://www.fide.com/official/handbook.asp?level=DD106 Regulations for the 2007 – 2009 World Chess Championship Cycle], sections 4 and 5, [[FIDE]] online. Undated, but reported in [http://www.chessbase.com/newsdetail.asp?newsid=3948 Chessbase on 24 Jun 2007]</ref> At the same time FIDE announced that, as compensation for being denied entry to the 2007 tournament, Topalov would have special privileges in the [[World Chess Championship 2010]] cycle.

==Qualification process==
The top four finishers of the [[FIDE World Chess Championship 2005|2005 FIDE World Championship]] event were granted direct entry into the 2007 event. However, [[Veselin Topalov]], [[FIDE World Chess Championship 2005|FIDE World Chess Champion 2005]], was replaced by [[Vladimir Kramnik]], Classical World Chess Champion, after losing his unification match to him in the [[World Chess Championship 2006|2006 World Championship]].

Four further players qualified through the 2005–07 qualification process, which consisted of three stages:
#Continental championships
#2005 World Cup
#2007 Candidates Tournament

===2005 World Cup===
{{main|Chess World Cup 2005}}

The 2005 World Cup, held in [[Khanty-Mansiysk]], Russia, was the qualification for the Candidates tournament. It was a knock-out tournament of mini-matches, in the style of the [[FIDE World Chess Championships 1998-2004]]. However, once 16 players were left, they were no longer immediately eliminated, but played further mini-matches to establish places 1 through 16.

The top finishers were:<ref>[http://www.mark-weeks.com/chess/a5a7$iix.htm 2005 FIDE World Cup Results] at [http://www.mark-weeks.com/chess/wcc-indx.htm Mark Weeks' World Chess Championship Index]</ref><ref>[https://theweekinchess.com/html/twic580.html The Week in Chess 580]</ref>

The top 10 qualified for the Candidates Tournament. Since Bacrot was already qualified on rating, 11th placed Malakhov also qualified.

===2007 Candidates tournament===
One place in the [[Candidates Tournament]] was reserved for [[FIDE World Chess Championship 2004|2004 FIDE World Champion]] Kasimdzhanov, who had also finished 6th in the [[FIDE World Chess Championship 2005|2005 championship tournament]]. Five places were then awarded to the five [[Elo rating system|highest rated players]] (average of July 2004 and January 2005 ratings): Leko, Adams, Polgar, Shirov and Bacrot. The remaining ten places went to the highest finishers at the [[Chess World Cup 2005|2005 World Cup]] who had not otherwise qualified (see above).

The Candidates tournament, held in [[Elista]], [[Kalmykia]], Russia, from 26 May to 14 June 2007, was originally to consist of a two-round [[Single-elimination tournament|knockout]] with one player qualifying from each quarter of the draw. In September 2006, FIDE proposed that these players play a 16 player, single round-robin tournament instead.<ref>[http://www.chessbase.com/newsdetail.asp?newsid=3365 FIDE proposes Candidates tournament 2007], Chessbase, 24 September 2006.</ref> However this decision was reversed, and the tournament consisted of two rounds of matches as originally planned.<ref>[https://theweekinchess.com/html/twic654.html The Week in Chess 654], [[The Week in Chess]], 21 May 2007</ref>

World Cup winner Aronian was top seed, with the remaining players seeded in rating order according to the January 2006 ratings list. In the second round, the 1v16 winner played the 8v9 winner, 2v15 winner versus 7v10 winner, and so on.

====Match conditions====
Matches were best of six games, at normal time controls (40/120, then 20/60, then 15 minutes + 30 seconds per move). Where matches were tied after six games, tie breaks were played on the seventh day:

# Best of four rapid games were played. Rapid time control was 25 minutes for the game, plus 10 seconds per move.
# Where the score was still tied, best of two blitz games were played. Blitz time control was 5 minutes for the game, plus 10 seconds per move.
# If the score was still tied, the players would have drawn lots for a single sudden death game where White had six minutes but needed to win, Black had five minutes but only needed to [[draw (chess)|draw]]. This final stage of tie break, called an [[Armageddon chess]] game, was never required.
