Types of Regular Chess - Standard, Blitz & Bullet

On ICC, there are three separate categories for regular chess: Standard, Blitz and Bullet. The estimated time, abbreviated as etime, of a game determines in which category the game falls. The formula for etime is:

• etime = Starting time + (2 * Increment / 3)

This means that the etime is the starting time, plus two thirds of the increment. For example, a 2 12 game is a game that has 2 minutes on the clock and after each move, 12 seconds are added. The etime is calculated with this formula:

• (2 (Starting time of 2 minutes.) + 8 (2 * 12 / 3).  Therefore, a 2 12 game has an etime of 10.

Standard		etime of 15 minutes or more.
Blitz		etime of 3 minutes or more but less than 15 minutes.
Bullet		etime of less than 3 minutes.
