Online Playing Rating Types
Chess Tempo uses the following rating types to help differentiate performance on games with different time
controls:
- Bullet
-
Estimated time of less than 3 minutes.
- Blitz
-
Estimated time greater than or equal to 3 minutes, and less than 15 minutes.
- Rapid
-
Estimated time greater than or equal to 15 minutes, and less than 1 hour.
- Long
-
Estimated time greater than or equal to 1 hour, and less than 12 hours.
- Correspondence
-
Estimated time of 12 hours or greater.
Estimated time for games with no increment is simply the initial time on the clock. Time for games with an
increment are calculated by assuming the game will go for 40 moves. For example, 5 minutes start time with a
12 second increment would lead to an estimate time of 5*60+12*40 which equals 780 seconds, or 13 minutes, leading
to a classification as a blitz time control. Increasing the increment to 18 seconds would produce 5*60+18*40,
giving an estimate of 17 minutes, which would now be classified as a rapid time control.
