Every online game starts with a clock. The time control decides how much you can calculate, how much you can bluff, and which mistakes are likely. Choosing the right format is part of choosing the right training.

Reading the notation

1+0 means one minute for the whole game with no increment. 5+3 means five minutes plus three seconds added after every move. 10+0 is ten minutes with no increment. 60+0 is one hour each.

What increment does

Increment rewards long games and precise technique. With 5+3, a 40-move game gives each player an extra two minutes, so the clock pressure is different from 5+0. Without increment, every move costs time and the endgame can become a scramble.

Which format should you play?

If you are learning an opening or working on calculation, rapid is usually the best laboratory. Bullet is fun but it rewards reflex more than understanding. Classical is excellent for deep work but hard to fit into a busy week.

A practical mix: mostly rapid for improvement, some blitz for pattern speed, and occasional classical for a serious game. ChessUrge supports controls up to one hour, so you can choose the format that matches the session.

Pick a time control on the play page and review the game afterwards in the library.
