heyo: I agree that the system is flawed, and the unsportsmanlike players who refuse to admit that they've lost are very annoying. But I would oppose any change in the rules that turns the game into something that is not traditional Go. I don't want to play something like Go. I want to play Go.
I don't have a big problem with the rules the way they work now. The playing of Go requires a certain amount of courtesy. And the current rules force players to learn courtesy and sportsmanship.
Occasionally, this means asking Fencer to end a game. I'm sure this annoys Fencer, but he's been doing it for a while, so it can't be that bad. Previously on this board, it has been suggested that some members be appointed to adjudicate disputed games. I still think this is the best solution.
