There's no fool-proof way to identify someone cheating, but when the

It might be reason for suspicion, but perhaps not strong suspicion.

I mean, in half the games where lag appears, through nobody's fault,
you'll be ahead on time - completely randomly. In half the games where
lag appears, through nobody's fault, randomly, you'll be winning on the
board.

Put those two together and 75% of the time, when lag appears midway
through a game, you'll have one of the two conditions which most people
would use as evidence of cheating.

I mentioned "confirmation bias" in another thread, and this is another
instance where you need to be careful of it. When you're ahead on the
clock, or have a winning position, you tend to REALLY notice when all of
a sudden your opponent's connection gets laggy.

If the position is even, or your opponent is better, or your opponent
has plenty of time ... you tend not to notice at all.
