Correspondence chess is chess played by various forms of long-distance correspondence, traditionally through the postal system . Today it is usually played through a correspondence chess server, a public internet chess forum, or email . Less common methods that have been employed include fax , homing pigeon and phone. It is in contrast to over-the-board (OTB) chess, where the players sit at a physical chessboard at the same time; and most online chess , where the players play each other in real time over the internet. However, correspondence chess can also be played online.

The current president is Eric Ruch . Some sources say that correspondence chess was already played in the 12th century. Most chess historians doubt whether this

220-605: A Ministry of Environment and was the first country in the world to implement an environmental law in 1973. To mitigate environmental degradation and global warming the Danish Government has signed the Climate Change-Kyoto Protocol . However, the national ecological footprint is 8.26 global hectares per person, which is very high compared to a world average of 1.7 in 2010. Contributing factors to this value are an exceptional high value for cropland but also

330-614: A temperate climate, characterised by cool to cold winters, with mean temperatures in January of 1.5 °C (34.7 °F), and mild summers, with a mean temperature in August of 17.2 °C (63.0 °F). The most extreme temperatures recorded in Denmark, since 1874 when recordings began, was 36.4 °C (97.5 °F) in 1975 and −31.2 °C (−24.2 °F) in 1982. Denmark has an average of 179 days per year with precipitation, on average receiving

440-581: A temperate climate . Denmark exercises hegemonic influence in the Danish Realm , devolving powers to handle internal affairs. Home rule was established in the Faroe Islands in 1948. Greenland obtained home rule in 1979 and further autonomy in 2009. The unified Kingdom of Denmark emerged in the 8th century AD as a maritime power amid the struggle for control of the Baltic Sea . In 1397, it formed

550-542: A two-chamber parliament . Denmark faced war against both Prussia and the Austrian Empire in what became known as the Second Schleswig War , lasting from February to October 1864. Denmark was defeated and obliged to cede Schleswig and Holstein to Prussia . This loss came as the latest in the long series of defeats and territorial losses that had begun in the 17th century. After these events, Denmark pursued

660-412: A certain number of hours, they will exceed the time limit in a given game. Chess is a game with great traditions dating back to the late sixth century.

770-449: A fee. Also more casual servers allow the use of nicknames, and have a real-time rating system which often adjusts a player's rating after each rated game. Casual servers also tend to have a wide range of facilities, such as online games databases, social and chess improvement forums, teams, and player homepages. More traditional correspondence chess servers often charge per tournament and force the use of real names. For example, competitors in

880-668: A few key trading posts in Africa and India . While Denmark's trading posts in India were of little note, it played an important role in the highly lucrative Atlantic slave trade , through its trading outposts in Fort Christiansborg in Osu , Ghana through which 1.5 million slaves were traded. While the Danish colonial empire was sustained by trade with other major powers, and plantations – ultimately

990-537: A forced checkmate in 28 moves. The World Team voters resigned on October 22. After the game Kasparov said "It is the greatest game in the history of chess.

Denmark – in Europe  (light green & dark grey) – in the European Union  (light green) Denmark

1100-525: A framework laid out in the Constitution of Denmark . First written in 1849, it establishes a sovereign state in the form of a constitutional monarchy , with a representative unicameral parliamentary system .

1430-727: A lack of resources led to its stagnation. In the Thirty Years' War , Christian tried to become the leader of the Lutheran states in Germany but suffered a crushing defeat at the Battle of Lutter .

Denmark managed to avoid territorial concessions, but King Gustavus Adolphus ' intervention in Germany

1540-464: A policy of neutrality in Europe. Industrialisation came to Denmark in the second half of the 19th century. The nation's first railways were constructed in the 1850s, and improved communications and overseas trade allowed industry to develop in spite of Denmark's lack of natural resources. Trade unions developed, starting in the 1870s. There was a considerable migration of people from the countryside to

1650-514: A recent rise in popularity as applications on these devices. Usually the devices use wireless internet or SMS technology to submit their moves to a central server.

Email play has gradually declined in popularity due to issues such as email viruses, opponents' claims of not receiving moves, and similar impediments to

1760-475: A relatively high value for grazing land, which may be explained by the substantially high meat production in Denmark (115.8 kilograms (255 lb) meat annually per capita) and the large economic role of the meat and dairy industries. In December 2014, the Climate Change Performance Index for 2015 placed Denmark at the top of the table, explaining that although emissions are still quite high,

1870-546: A short period, but its successor proved to be viable and successful. On 2 December 1928, a new federation was formed in Berlin .

The Kingdom of Denmark is a unitary state that comprises, in addition to metropolitan Denmark, two autonomous territories in

2090-767: A time (an exception being a simultaneous exhibition ), correspondence players often have several games going at once. Tournament games are played concurrently, and some players may have more than one hundred games continuing at the same time. Time limit in correspondence game is not rigidly defined, but it is generally accepted that, on average, it is never less than one day per move (not counting transmission time in postal chess). This time allows for far deeper calculation, meaning that blunders can be less frequent. Certain forms of assistance, including books, chess databases and sometimes chess programs , are often allowed. Books and opening databases are almost universally acceptable, but organizations vary as to whether chess engine use

2200-560: A total area of 42,943 km (16,580 sq mi), metropolitan Denmark consists of the northern part of the Jutland peninsula and an archipelago of 406 islands.
