Darned premoves
i don't think so, they are not premoves, since I saw cleary seconds passing until the timeless party moved... it's a software bug, maybe adminstrators could answer, or better correct the issue?
Are the administrators going to look into this?
The code has definitely changed lately. If one looks closer, the white disc with circle - for unrated games - looks bigger than a few days ago (in the graphic screen for challenges) - this is a sign that shows the code was modified recently. I think it also has something to do with the clocks displayed next to the chess board.
My opponent just continued his play about 7-10 moves even his time has ended. Sometimes his clock just stopped for few seconds and continued again. There have to be something very weird. 
I'm glad others agree, let's hope administrators will look into this soon!...
I'm watching some live chess games and the clock on the lower side seems to always be faster than the higher side, regardless of who's playing (I noticed that through various games/players). At some point, the upper side has, let's say, 23 seconds left while the lower side seemes to have 0 seconds left (and the time is set to simple bullet 1 0 , i.e. 1 minute 0 seconds). Then, they continue to play for several moves and seconds, even with the lower side clock showing 0. ANY IDEA? Has chess.com updated something recently in their systems?
