Why are there different ratings in live chess?
Live Chess has three different ratings based on different time controls:
- Bullet rating - For games under 3 minutes.
- Blitz rating - For games over 3 minutes but under 10 minutes.
- Rapid rating - For games 10 minutes and longer.
We keep these rating separate because of the largely different skills involved in playing shorter or longer games.
The per-move bonus time is significant - not just the base minutes.
The system assumes an average game-length of 40 moves to estimate the total length of time available to each player; the result is what determines which rating is affected by a given time control:
A time control of 2 | 12 therefore results in a Rapid (not Bullet or Blitz) game like so:
2 minutes + (12 seconds x 40 moves = 480 seconds) = 10 minutes
As a reference, here are some examples of presets available in Live:
|Time Control||Estimated Length||Game/rating type|
|5 | 0||5 minutes||Blitz|
|10 | 0||10 minutes||Rapid|
|2 | 12||10 minutes||Rapid|
|3 | 0||3 minutes||Blitz|
|4 | 4||6.5 minutes||Blitz|
|15 | 10||22 minutes||Rapid|
|1 | 5||4.5 minutes||Blitz|
|1 | 0||1 minute||Bullet|
