@The OP,
I think that's probably a problem with your own internet. It happened to me before, but I am sure it's always a internet lag. When it says "Connection Interrupted." Your Internet is having problems, and you can see your opponent's time keep running.
It says "SoAndSo" has disconnected In the chat box, then they did disconnect,
In other words, you are probably the one that disconnected(even though you are not willing to) due to your internet lag.
Correct me if my assumptions are wrong.
CHEATER ARE USING DISCONNET TO WIN!
It happened to me 7 time in two days. I have a winning position over a player with a better raking. All of sudden the disconnect goes on. When it reconnects all my time is gone and I lose. The other player never loses time. It never happens in an even game or with a player close to my rank. I'm convinced that these player know how to activate disconnect and do it on purpose. THIER CHEATERS. Is anyone else having the same problem?
