There are four types of regular (not atomic, wild or bughouse) chess played on this chess server: Untimed, Lightning, Blitz and Standard.
A game is "Lightning" if the expected duration of the game is 3 minutes or less per player. "Expected duration" is determined by a formula that takes into account both the Start time and the Increment (Inc) value. Here is the formula:
Expected duration = (Start + Inc*2/3)
The following table shows the slowest Lightning and fastest Blitz time controls, the dividing line if you will between those two types of matches.
Slowest Lightning | Fastest Blitz | ||
Mins | Incr | Mins | Incr |
0 | 4 | 0 | 5 |
1 | 2 | 1 | 3 |
2 | 1 | 2 | 2 |
3 | 0 |
As you can see, Lightning chess is very quick!
