psuChess (pronounced soo-chess) is a site designed to give two people an easy, graphical way of playing correspondence chess online. It is not a chess-computer - i.e. you cannot play against it - your opponents will be real people, somewhere in cyberspace.

Obviously, any form of correspondence chess - and psuChess is no exception - requires a certain amount of trust between players. If your opponent is going to employ the help of experts, or an expert computer program, to make their moves, then they are wasting your (and their) time. This game was designed for people who would like to play a leisurely and friendly game, making a move once a day, say, perhaps last thing before leaving the office...

In so far as they are relevant, psuChess adheres as closely as it can to the laws of chess as laid down by FIDE.


psuChess can be played in two modes:

  1. The default mode, whereby players are notified by email when their oppoent has made a move.
  2. A "live" mode, whereby a player's board is updated automatically when an opponent has made their move.

The latter does, of course, mean that both players have agreed to play this way, and are each aware that the other is online. This in turn is predicated upon the two having communicated privately beforehand to agree this, which means they know each other, at least in cyberspace, as psuChess does not facilitate communications between strangers, nor divulge players personal details.


When registering, players are asked to select their skill level (which can be changed later). This setting in a user's profile allows other users to choose opponents of the level they wish to play. Players can, via their profile settings, decide not only who they wish to challenge, but also who can challenge them. (For example, a Master may not wish to be challenged by a Beginner.)

Players can therefore opt for complete privacy by disallowing challenges from any level. How then can they play? Well...

... players can maintain two lists of players (usernames): those they will allow challenges from, and those they specifically want to block from challenging them.

The former will be other users personally known to the player, with whom they have privately communicated their username. The latter is just in case a player is repeatedly challenged by someone they do not wish to play.


Challenge notifications are sent by email, and the recipient must log-in to their account here to accept or reject them.

The challenger can opt to decide who will play which colour, or to allow their would-be opponent to choose, or they can decide to "roll a dice" - i.e. let the psuChess server decide randomly.

Privacy policy

No tracking is used on this site, not even site analytics.

The only personal details required of registrants is an email address. A full name is optional, and is only used to personalise emails the site may send when notifying users of their opponents' moves. Neither email addresses nor names will ever be divulged to other users, or to any third party, other than (potentially, though hard to see why) for any legal demands.

For logged-in users of this site, a cookie (a small text file) is stored on your oomputer, allowing the site to identify your site membership details in order to show you appropriate content - i.e. your games, profile etc - without having to log in anew on every page.. If you have ticked the "Remember me on this computer" checkbox when logging-in, this cookie will remain on your computer, and only deleted after 90 days of inactivity on this site. Otherwise, it will be deleted when you next log out or close your browser.

If an account is deleted, all personal details are also deleted. However, if any games have been played with other users, the record of these will be retained, and the associated account username changed to a random string.
