When playing on the server:

 

   You cannot take back moves in rated games.

 

   Your games are public, other people can watch them live on the server.

 

During the game you can use some special techniques, such as single click entry, dropping and "premove". These are described in the section on single click entry and in Server settings.

 

Game buttons

At the top right of the board window you have a number of buttons. If you move your mouse pointer over them you will see their function.

 

 

 

The functions are

 

  Reconnect: in case there is a problem with your Internet access

 

  Abort/Adjourn game: Your opponent must agree to do this.

 

  Offer draw: This sends an automatic chat message and your opponents draw button will start blinking.

 

  Accept draw: Click on the blinking draw button to accept the draw offer of your opponent.

 

  Decline draw: Click on the exclamation mark to decline a draw offer. Simply making a move will also decline the offer.

 

  Resign: The game ends - your opponent wins.

 

  Applause: You can applaude your opponent for the game. The server keeps track of the applause , which improves his social status.

 

  Claim win on disconnect: If your opponent has been offline for a long time you can claim a win with the disconnect button.

 

  Offer rematch: This is the best way to immediately play another game, with reversed colours.

 

  Start Analysis: You can analyse the game with your opponent. This is know as a "postmortem".

 

  Ping opponent: This sends a ping to your opponent and displays the lag time in the chat window.

 

FIDE draw rules

For games on the Fritz server the FIDE laws. The exact details may not be known for claiming a win. For instance, is it correct if a player claims a win on time in a position in which he has only a king and a bishop? Many people assume this is generally forbidden (insufficient material).

 

But consider the following position:

 

 

White can actually claim a win on time, according to the FIDE rules. The reasoning is that his opponent could lose the position if he plays really badly: 1...c1N 2.Kc2 Na2 3.Bb2#. That is all that counts: the theoretical ability of one side to lose the game.
