[edit] Introduction

In the face of criticism of the Knock-Out FIDE World Chess Championship tournaments held from 1998 to 2004, FIDE (the International Chess Federation) made changes for its World Chess Championship in 2005. It used normal (slow) time controls (unlike the 2002 and 2004 Knock-Out tournaments), and changed the format to an eight player, double round robin event, where every player plays every other player twice, once with each colour.

The players invited were:

The finalists from the previous (2004) FIDE World Championship: Rustam Kasimdzhanov and Michael Adams;
Classical World Champion Vladimir Kramnik, and his most recent challenger, Péter Lékó;
The next top four rated players: Garry Kasparov, Viswanathan Anand, Veselin Topalov and Alexander Morozevich.^[1]
Kramnik refused to play,^[2] as did the recently retired Kasparov. Their places were taken by the next two players on the FIDE rating list: Peter Svidler and Judit Polgár.

The participation of Judit Polgár made her the first woman to compete for the world chess championship.

The opening ceremony took place on September 27, the matches started on September 28, and the closing ceremony took place on October 16.

The first tie-break was head-to-head results, the second tie-break was total number of wins.

Topalov scored an extraordinary 6.5/7 in the first cycle, one of the greatest streaks in the history of championship-level chess. He then drew every one of his games in the second cycle, clinching the victory with one round to spare. This made Topalov the FIDE World Chess Champion.

[edit] Aftermath

FIDE declared before the tournament that they would regard whoever won as World Chess Champion. However, the non-participation of "Classical" World Champion Vladimir Kramnik meant that there were still two competing claimant to World Champion: FIDE Champion Topalov, and "Classical" Champion Kramnik.

Although Topalov initially declined^[3] Kramnik's offer^[4] to face Kramnik in a reunification match, Topalov later acceded; the two later contested the FIDE World Chess Championship 2006 to reunify the title^[5] with Kramnik emerging the winner.
