Time Hacker,

Hello All,

I have observed a player some how hacking the clock.

I was playing with , I noticed after the clock goes below 20 seconds, He is resetting the clock to 20 again and again. And finally I lost on time. 

Anyone else has seen this before?

Thanks,

Bluezappy

Do a "search forums" (that little box in the upper right) for "lag".  That's the most likely explanation.  Some reject the idea that a browser based application can't be hacked and insist that there must be mischief afoot.  If it really bugs you then try correspondence chess (what Erik insists on calling "online" chess).  Play enough games so you have to rush from one to another and it's almost like blitz. 

EDIT Staff kind of frown on "naming and shaming" in the forums so you probably don't want to name your opponent if you're going to accuse them of something.  For serious accusations, file a support ticket.

In harmony with what baddogno said, try these links.

And also, please no naming and shaming, thanks!
