Sports licence
To play in official chess tournaments in Turkey, a player needs a sports licence registered with the Turkish Chess Federation and validated for the current season. Licensing and validation require the documents and fees set out in the current announcements of the federation and the Provincial Directorate of Youth and Sports. Our club guides members through licensing and club registration.
National rating (UKD)
The UKD is Turkey’s national rating, calculated from results in official tournaments played in Turkey. After playing their first rated tournaments a player receives a starting rating according to federation regulations; after each later tournament the rating is updated based on opponents’ ratings and results. UKD lists are published regularly by the federation.
FIDE rating
The FIDE rating is the international rating system of the World Chess Federation. Players in tournaments reported to FIDE receive their first FIDE rating after playing a certain number of rated opponents. Separate ratings are kept for classical, rapid and blitz games. In FIDE calculations, rating differences of more than 400 points are counted as 400.
How is a rating change calculated?
For every game a player’s expected score is calculated from the rating difference between the two players. The difference between the actual result and the expected score is multiplied by the development coefficient (K) to give the rating change. Use the Rating Change Calculator on our website to see the estimated change after a game.
Rules on rating systems are updated from time to time; for definitive information, refer to the official regulations of the federation and FIDE.
