Lag in chess
Lag refers to the delay (latency) between your device and the game server. When latency is high, you may notice delays during gameplay, such as moves taking longer to appear or brief interruptions in your match.
More lag means it takes longer for your moves to reach the server, which can make it seem like you are moving more slowly. This might cause delayed moves, irregularities in the game clock, or, in severe cases, disconnections.
Lag forgiveness
Lag typically doesn’t have much impact in longer games like standard chess, but it can make a big difference in fast time controls like blitz or bullet. To keep things fair, Chess.com’s game timer accounts for lag when calculating how much time you actually used for a move.
The system automatically compensates for some lag, up to a set limit. If you notice your opponent’s clock occasionally gaining a second or two after their move, it means they have a poor connection and the system is compensating for their delay.

How can I check my connection strenght?
Next to each player’s name, you’ll see a set of bars that indicate the strength of their connection:
Connection status

Details |
Excellent connection | Very low lag — has full bars.

OK Connection | Some lag — has one or two bars.
|
Poor Connection | High lag — has one bar.

Disconnected | If the bar turns RED and the clock is flashng, that means you are disconnected!
