What is Standard chess?

A game with a time control greater than or equal to 15 minutes is  'standard' chess. 'Standard' is one of the rating categories in your personal profile or 'finger'

The exact boundary between 'standard' and 'bullet' or 'blitz' is defined by 'etime'.
Etime is the time + 2/3 increment.
Bullet       -- Games with etime < 3
Blitz         -- Games with 3 <= etime < 15
Standard -- Games with etime >= 15
A bullet game is 0 1,  0 2,  0 3,  0 4,  1 0,  1 1,  1 2,  2 0  or  2 1.
A blitz game is 0 5 - 22,  1 3 - 20,  2 2 - 19,  3 0 - 17,  4 0 - 16,  5 0 - 14, 
6 0 - 13,  7 0 - 11,  8 0 - 10,  9 0 - 8,  10 0 - 7,  11 0 - 5,  12 0 - 4,  13 0 - 2,  14 0 - 1.
(0 5 - 22 stands for 0 5,  0 6,  0 7,  0 8,  ---   0 21,  0 22)
Standard is the rest with the maximum time control of 600 300.
Examples:
Where 0 22 is blitz, 0 23 would be standard.
Where 13 2  is blitz, 13 3 would be standard.

Standard time control games count towards your standard rating, not your bullet or blitz rating. Games played in the 15-minute and 45-minute pool count towards the 15-minute or 45-minute rating, not the standard rating.
