Many of their hobbies include chess, so they rarely play chess due to busy work or other important activities. Indeed, there is online chess via cellphone, but this also takes up the mind for a certain period of time. For those who are busy, you can try CHESS CORRESPONDENCE type. On chess sites there is a feature for playing this type of chess on online chess services, but it is not official. For example, on CHESS.com there is an ONLINE CHESS feature. The characteristic of correspondence chess is that the chess game is played for a very long time, not just hours but can be daily or even weekly, monthly for just 1 game. So what’s official? If you want to take part in official correspondence chess, please join ICCF. ICCF stands for International Correspondence Chess Federation. Formerly it was called the International Correspondence Chess Association (ICCA).

ICCF was founded in 1953 and the current president of ICCF is Eric Ruch. Even though the organization is separate from the normal CATUR parent company, namely FIDE, ICCF maintains good relations with FIDE. So what are the benefits of joining ICCF? Because it is official, we can take part in the Official Correspondence Chess Championship which is recognized worldwide, get an official Chess TITLE, hold friendly matches between countries, and so on. Due to the nature of correspondence chess, which takes a long time per move, we can compete on 100 chess boards at once. Before the advent of COMPUTERS and the INTERNET, Chess correspondence was done via LETTER. Even now you can still use this traditional method. However, most have switched to WEB-based or via email.
