It shouldn't have disconnected then..... shame if you were playing really well
Disconnected with 2 moves to win..*crys*
It happens and there is a warning on this part of the website telling that you may be disconnected, the staff here is working to try solving those issue.
Sorry for your bad experience, I think you just had a bad luck (it happened to me too) but even with its defects, I still think that live chess is a huge addition to this website.
Cheers
Was playing a super good game and had 2 moves till checkmate and the app disconnected me while I was waiting for opponent to move (not sure if he/she hacked to disconnect me) but it sucked.
