You can play private games with any registered player. These games are called private in contrast to the "official" games played in tournaments. They differ in several respects:
The normal mode of playing is identical to tournament games.
Playing a private game
You can play a casual game by visiting the directory of open challenges (follow the link on your player homepage).
Creating a new challenge
All players can create public challenges. These public challenges can be accepted by every player. Members can even challenge specific players.
On the challenge page you enter the parameters of the game and select an opponent. Please enter the following values:
Challenged player. This is the name of your opponent. Please enter the player name in correct case. Replace any blanks in the player name with an underscore character "_".
Your color. Select your preferred color. If you select Random, the system will determine the color after your opponent accepted the challenge.
Initial time and increment. The initial time is on the clock when the game is started. After each move, the increment is added to the clock of the player making that move (Fischer clock). You can set the increment to 0, creating a fixed time schedule of x days for the whole game.
Max. time on clock. If the time increment per move is not 0, the time on the clocks can get arbitrarily large if the players play fast enough. To prevent this, you can set an upper limit to the clocks.
Example: You have 29 days on your clock. The time increment per move is 3 days and the upper limit for the clocks is 30 days. After your next move your clock will show 30 days and not 32 days as would be without the upper limit.
Publish. The challenger decides if the game should be visible for the public, or if the whole game or the moves and notes of the players should be hidden. This cannot be changed lateron.
Accept or decline a challenge
If someone challenges you, a corresponding note appears on your player homepage. Simply click on the accept or decline link to start the private game or decline the challenge.
Your private games appear in the lists "You are to move" and "Opponents to move" on your player homepage, just like tournament games.
Unanswered challenges are deleted automatically after 7 days.
List of private games
You can see the private games of a player by following the corresponding link on his player information page. This list contains only those games that were flagged as public when issuing the challenge. But if you visit your own list of private games, you will see all your private games, disregarding their publishing state.
