Asking opponent if the game is finished before the dame are filled
At the end of the game, as the dame are being filled, it is necessary to decide whether one needs to make reinforcing moves within one's own territory. If these moves are unnecessary, they would cost points.
It is tempting to seek the opponents agreement that the game is over before the dame are filled in order to avoid having to make this decision.
This is a bad habit.
I think the best practise is to play out the dame as part of the game; in a timed game, within one's alloted time. Don't start a conversation about whether the game is over, but wait for two passes.
blubb: I second that request, particularly because it resolves the most common chinese vs. japanese scoring conflict.
