I guess this is a more practical question. I have managed to get a FIDE ID from my country’s chess federation (ECF). but I’m not sure how exactly I’m supposed to register for FIDE-rated tournaments. I found this site, but I don’t know where I should be signing up for one of these. I appreciate any help from anyone that has experience with this.
All FIDE rated tournaments have to be registered in advance with FIDE. How long before varies according to the type of tournament but this means that FIDE know in advance when a tournament will be and they publish this information on their website.
The general page is here. This includes a drop down box at the top which allows you to select a particular country / federation and see the upcoming tournaments in your country.
So, for instance, if I select "USA" and click "Search" I get this page which shows "Tournaments Registered for February 2022" for the USA. This confusing title means that these tournaments are registered to report their results in time for inclusion in the February rating list. This means that tournaments which are due to finish during January in time for the organiser / arbiter to submit results before the end of January will be included. Tournaments which finished in the last few days of December will also be included where there wasn't enough time for December submission.
