Can People Cheat on the Clock in a 1-minute game?

I had the guy beat.  I had 2 seconds and he had 0.4 seconds.  I was moving very quickly.  He made EIGHT moves and his clock STILL had 0.4 seconds on it.  Is he a cheater?  Am I missing something? Thanks.

I am new user and found the same thing and could no believe it...but if you go into your settings you will see an option to PRE move. That is you can make your move before the opponent does, and if it is legal it will take the move. For speed chess this is a very useful setting and will save you lots of time when in short time controls. From a won position it is very easy to make forcing moves with very little time. If all the moves are legal no time would come off your clock.

They are not cheating.

You are missing about the issues or premoves and lag compensation, which are explained in FAQs somewhere.

hmmm..."premoves"

Is that kind of like answering my wife before she asks the question?

I don't like that rule but I will live by it. Thanks for the help.

Yes, pre-moving is not cheating. 

However, there are tactics against premoving:

1. Make moves your opponent doesn't expect. 

2. Or better: Make a move that makes the move your opponent has premoved illegal (e.g. checking at all cost). He can't do the premove then and will have to think again, which if he has only 0.4 seconds left, will probably loose the game for him. 

Good look.

Sorry @thougtdancer - you got sucked into a debate with a return troll; their latest account has been disabled, and I've deleted most of the posts quoting their content as no longer relevant.

Of course cheating is possible, and Chess.com puts considerable resources into detection and monitoring - for example, see

Cheating can be discussed in private clubs such as https://www.chess.com/club/cheating-forum, but not in the public forums - we don't really want to teach people how to go about cheating, so I've removed some of that technical documentation as well.

I am also now locking this thread.
