When the game starts, have a grayed-out "Lag-abort" button. If the

So, if you think you can still win even against the lag-cheating,
you have the option of playing on and picking up the rating points
or ducats.

Sounds like about the best you can do. The only problem I can see is
that it gives people the incentive to start lagging if they look like
losing, in the hope that the opponent will abort the game instead of
winning it. But I don't see a way round that.
