it's funny how the vast majority of opponent disconnections, and I mean 99%+, happen immediately after a blunder or a moment in the game where it has become clear that the disconnector's position is very bad.
In my games, it's highly doubtful this is related to random dropped connections due to a poor internet.
Literally I have not had an opponent randomly disconnect (meaning, not immediately after a blunder or the situation on the board becoming clear that they're dead in the water) in over a year.
that's been my experience at least. it's true that it could be a random dropped connection due to an internet issue, but overall that's not very likely. I can't recall ever being "saved by the disconnect" where an opponent was pounding me and then suddenly disconnected. If disconnects were random that would be expected to happen fairly often (and it does not).
There have been endless threads about players who disconnect. It's poor sportsmanship (usually), but can be an internet problem. I've disconnected involuntarily from games I was winning and others where I was clearly worse. Only the latter seem suspicious.
Lately, though, I've seen a growing number of disconnects from players with ratings 300+ below me. Are they pitching a fit because they lost to someone who should be expected to beat them at least 80% of the time?
Pathetic.
