The fourth FIDE Grand Prix will be the strongest in the series, and one of the strongest tournaments of the world this year. New functions on the FIDE website allow us to see the current rating changes of top-grandmasters. The average rating of the tournament in Nalchik will be around 2725 points based on the April 2009 list to be published soon. Previously the highest average rated tournament was held in the third stage of the series, Elista (2715 points).

The top-rated player of the competition is the World Cup 2005 and Olympiad winner Levon Aronian. Two players have also shown excellent results this year: Alexander Grischuk - the winner of the Linares and Elista super tournaments, and Sergey Karjakin, who won the Corus tournament in January in Wijk aan Zee. The World Cup 2007 winner Gata Kamsky this year has shown also a good performance during the Challenge match against Veselin Topalov. The tournament is so evenly balanced that every one of the 14 participants who comes to Nalchik is in a good position to win the tournament.

Time control: 120 minutes for the first forty moves, 60 minutes for the next twenty moves and then each player will be allotted 15 minutes after the second time control and an increment of 30 seconds per move will be allowed from move 61 onwards.

Games will be played from 15 April till 29 April every day. The rest days are 20 and 25 April. The total prize fund is 162,000 euros.
