I experience this today. In past year i not experience never, but now i experience it 2 times with 1 player at same match. I experience connect problems after i am winning clear. After that match i player with other people and i not experience any problem.
Again, your opponent has no way to do this. Their computer never talks to yours. The only way they could do this would be if they somehow gained control of the whole live server, and if they did that they would have access to much bigger stuff than simply cheating in the occasional game.
Connection glitches happen randomly at times. Causes could include a connection problem on your end, a connection problem for the server (although that would affect a lot of people), a connection problem somewhere between you and the server, or a server bug.
MGleason definately gets five stars for patience given how many time he has explained this (along with others) I blame films. They are good but make things such as hacking seem easier than they really are
I agree the issue could be anything in between the client and server (including the server) but it is not hacking of that I am certain.
I have not experienced this myself as I rarely play live chess, but I know how this sort of technology works.
I understand you reasoning, but still it was very strange. If it happens again, may be play in "lichess", there never is happen. I remember a long time ago also was happen. I no am playing through 4G, this is high speed ADSL, and never interrupt except there tell us beforehand. In that match it is happen a desconexion just may be 30 seconds or a little less, but this is a way too long time. I still will suspect a hacker's hand in this server, making not possible a conexion with me from the server. Wish you all best, and thanks for your answer. Daniel
