Chess Charts

There are following chart categories available for chess:

Chess chart

Chess chart is a list of the most active players. It is calculated in relative numbers. The maximum value – 10 points – is always attributed to the first position in the chart. This value is accounted while calculating a total rating of the user on the site.

Chess rating is in no way connected with the position in the chess chart.

The most successful players

This list includes those players bearing the highest ratio between won and lost games. This value is not accounted either while calculating a total rating of the user on the site, or while balancing his/her chess rating.

The most dynamic players

The list includes those players who has the most changed position in the chess chart as compared with last Sunday.

Chess rating

A system by professor Glicko is used to calculate chess rating.

Its main difference from Elo rating consist in the index of statistical error (rating deviation) which depends not on a player’s activity, but on the amount of time of his/her inactivity. The more he/she is idle, the more the discrepancy is. The discrepancy is individual for each player. Thus the rate of incrementation of a rating may differ between players after a game. The player who haven’t played for a longer time will have more incrementation. For example, a player can get 100 points for a win, but in the meantime his/her opponent can lose only 10. More details here.

A player has individual ratings for each type of game and time, that is games of different time and type of game are calculated separately.

Rating deviation

Rating deviation is used not only to determine rating gain more accurately, but to calculate player's activity rate also. At the present time the threshold value amounts to 70. You can see this value on chess statistics page. Those players who have value more than 70 do not participate in

  • Chess rating
  • The most successful players rating

Top users based on chess rating

Those players having the highest rating in a certain category of game and time are included in the top of the players. Apart from the high rating, the player should have rating deviation (RD) not exceeding 70.

To enter the rating you have to play often and successfully.

Very often (each day, as a matter of fact) we receive messages regarding chess timing problems. They go like this:

What should I do if in a lost position the opponent leaves for timing correction and doesn't come back for a very long time. Guest80732 is well known for it.

If I have to leave for a minute what should I do to suspend my timing? My opponents take advantage of it but I don't know which button to hit.

Dear users! Nobody here is fiddling with timing. It is theoretically very complicated in the current configuration of the applet, and practically impossible. Your opponent has precisely the same interface as you do and can not suspend or add time. All timing operations are conducted at the server's side.

I strongly recommend you to read:

Onsite chat is turned off at the moment. Online dialogue is allowed only during a chess game with the following limitations:

  1. Writing and sending messages is allowed only in your own time.
  2. Chatting is allowed only during a game. Chatting after a game will be accessible in the nearest releases.

If you have any questions or requests, please write them as comments to this post.

Chess applet

Chess applet is a special game window in which you can manage your chess game. It is important to understand that the game is played on a server and a user is given certain access to it based on his/her authorization data. The players can enter moves for "their" color of figures, the others may only watch them playing. Let's explore applet's controls.

  1. Offer a draw. You click on the button and make a move. Your partner can accept a draw or make his move. If he makes a move, the offer is rejected. You can offer unlimited draws.

  2. Propose to abort the game. You can do it without the other party's acceptance only if there were not less than two moves made in the game. In all other cases it is equal to a draw proposal, i.e. you click on the button and make a move. If your partner agrees, the game is aborted.
  3. Resign the game.
  4. Turning auto turning a pawn into a queen ON/OFF. Here you can see the OFF position. You will be prompted to choose a piece yourself (in due time, of course).
  5. Turning sound ON/OFF.
  6. Change the style of a board.
  7. Change the style of pieces.
  8. Boost your partner's time. If you trust him/her or just want to present a few seconds, use this button.
  9. Adjourn the game.
  10. Change the size of a board.
  11. Reload the applet. Possible in emergency cases.

Applet timing problems during a chess game

Sometimes certain timing problems arise in the applet during a chess game: the opponent's time is not counting or your time isn't counting during partner's move, etc. All you have to do is to click on "Reload" button in the upper right corner of the window.

How to place a seek for a game

You can create a game by two different ways. The first one, recommended and the most correct method is to place a seek. The second one is to manually find a seek of other users and accept it. We will not discuss the latter as you shouldn't have any particular problems with it: you either accept or decline conditions of the seek. So let's discuss the first way.

  1. Click on "Play" button. Say, being on the Home Page.
  2. You will see a window to place a seek. If you're a first time visitor to our site, you have to type in the code shown on the picture. Here you can also select the most appropriate time control.

    You can find more details regarding settings of a seek in the next post.
  3. After pressing "Send" button, the server will start looking for an appropriate partner. As soon as he/she will be found, a game will be created for you and you will be automatically transferred to a chess applet's page.

So the game is already created and we wish you all the best on your check patterns!

Before making a move or right during the game you can change the style of your chessboard or pieces using corresponding buttons.

You can find more details regarding all capabilities and buttons of the chess applet in the next post.

After the game is finished you will see something like this window:

Available buttons:

  1. Challenge you opponent for an iterated game on the same terms.
  2. Place a general seek on the same terms.
  3. Analyze the game. You will stay in the applet.
  4. Close the applet.

If you are an anonymous user (i.e. you haven't registered prior starting the game), you have to refresh the page of the site you're on now (regardless which one it is). You will see additional information in the status panel.

Though you haven't registered, a chess office is created for you. It is accessible by clicking a link on your status panel.

If you decide to register, played games and all other information (for example, rating) will not be lost.

How to adjourn the game

You can adjourn a game unilaterally only if you have more than 10 minutes for the rest of the game. If you have less than that, the game may be adjourned only with your opponent's consent.

The game is also adjourned in the case of disconnection. It is to be determined that the player who was to make a move has really adjourned the game. It means that he will not be able to create any game if his opponent has challenged him to play the adjourned game off.

If the opponent, who has put the game off, is going online, the user will see a notification on his Control Panel.

All adjourned games available on special page or games page.
