Blitz stall

Sort:

I have been playing 10 min blitz, several times when the opponent gets to a point where they have to think a bit before moving, their clock stops, says there is lost connection and a countdown starts in seconds, Just before the end of the countdown they make their move. Basically stalling for time somehow.  How do they do it? what to do?

They're not doing anything, it's just a server disconnect. Happens all the time.
