Correspondence chess is a distinctive form of chess in which games are played over a much longer period of time. This allows for deep analysis and requires a high degree of concentration, endurance and strategic understanding.
Unlike classical over-the-board chess, the players do not sit opposite each other at the board. Moves were traditionally transmitted by letter or postcard, whereas today they are played almost exclusively via online servers.
Correspondence chess has a long tradition. As early as the beginning of the 19th century, games were already being played over long distances. One of the earliest known games took place in 1804 between The Hague and Breda.
With technological progress, correspondence chess also evolved. Around 1845, games were already being transmitted via telegraph, which made communication significantly faster.
For many decades, postcards were the standard medium of correspondence chess. Players used specially designed cards to record moves and game data.
During the 20th century, correspondence chess gained international importance. Games often lasted for months or even years, which gave this form of chess its distinctive character.
Today, correspondence chess is played almost exclusively on dedicated servers, which makes organisation, time control and documentation much more efficient.
I play correspondence chess both nationally and internationally, mainly within the following organisations and formats:
International Master (IM), awarded in 2024
Winning this tournament was a major international achievement
Qualification for an ICCF World Championship semifinal
Modern correspondence chess allows the use of engines and databases. However, the human factor remains decisive when it comes to evaluation, planning and strategic direction.
