Internet chess server

An Internet chess server (ICS) is a server to facilitate the play, discussion, and viewing of chess over the Internet. Specifically, it is a server with a Protocol (computing) based on that of the original Internet Chess Server (now the Internet Chess Club).

= History =

The Internet Chess Server was created in the late 1980s by a group of volunteers. Although it was Computer bug and suffered from lag problems, the server was popular among a small group of chess enthusiasts. Over time, many features were added to the ICS, such as ELO rating system and support for Graphical user interface clients, and the server was made more stable.

In 1992, Daniel Sleator took over managment of the ICS. To be finished soon

= Protocol and access =

The ICS protocol is a simple, text-based variant of the Telnet protocol. It is sparsely documented and not standardized, although a few reference implementations and several Client (computing) exist.

In theory, an ICS can be accessed from any telnet client. That said, almost all User (computing) choose to play using a graphical client, commonly called an interface. Currently, the most popular interface is XBoard (and its Microsoft Windows counterpart, WinBoard). In recent years, however, it has lost ground to newer interfaces like BabasChess and Thief (chess).

In addition to standalone clients, many servers also offer Java platform interfaces that can be used directly from a Web browser. These are popular with new users and users of public computers.

Over the years, several Internet chess servers have been created. The Internet Chess Club, with over 30,000 members, is by far the largest server. The second largest server is the Free Internet Chess Server. Other servers include Chess Live, Chess.net, ChessAnyTime, as well as various local servers. However, these servers have significantly less membership than the ICC and FICS.
