Rating system

chessmail has a rating system that makes it easy for members to find opponents at their level.

New chessmail members need to complete 10 games before they are given a rating.

After completing a rated game, both players have their ratings re-calculated. The calculations are made based on the players’ ratings before the match began.

Ratings are based on the Elo rating system, as described on Wikipedia. chessmail uses the following formula:

EA = 1 / (1 + 10 ^ [(RB - RA) / 250])

  • EA: Expectation that Player A will win
  • RA: Player A’s rating at the start of the game
  • RB: Player B’s rating at the start of the game

Once the game is over, the rating is calculated using expectation EA.

R''A = R'A + k * (SA - EA)

  • R'A: Player A’s rating at the end of the game
  • k: The k-factor for chessmail is 20, and sets the maximum number of points that can be won
  • SA: Result of game (1 for win, 0.5 for draw, 0 for loss)

The points the winner receives are deducted from the loser. Games that are abdicated before the 7th half-turn are not rated, except for rated tournament games. These are always rated.

Thinking time

When you are invited to a chess match, the thinking time can be set to between 24 hours and 30 days per turn.

If your opponent exceeds the thinking time, the match is displayed in red in your "My Games" list.

You can then end the game in your favour in the detailed view for the game. However, you don’t have to do this, and can refrain from doing so if you know your opponent cannot play right now, for example.

If the time has been exceeded, chess matches can be ended with or without a rating. However, tournament games can only be ended with a rating.

Setting holidays

You can set breaks in your user settings.

During breaks in play, you cannot make any moves on chessmail. In addition to this, the timer for your pending moves is paused and extended by the length of time you are on holiday for.

The letter (P) appears in your current games list just before an opponent’s break begins to show you that their thinking time has been extended. While an opponent is on a break, you matches with them are shown in grey.

Breaks can be cancelled.

Member names

Member names – the pseudonyms of the chessmail users – are colour-coded and have different fonts to indicate their status.

  • Online: Members who are online are underlined in blue.
  • New: New members who do not yet have a rating are shown in grey.
  • Opponent: If you are playing a match with a member, their name is shown in green.
  • Starred: Players you have given a star to are shown in bold. Give stars to players you really like playing chess with.
