My apologize, I trusted too much that GnuGo's score estimator would have handled Chinese rules. So end result was not w+½ but b+½, because black filled the last dame.It looks like that indeed mirror go in handicap games is a problem for gobots. I think that if it is abusive then it should be dealed as any other sandbagging or rating abuse, i.e. deranking. I do not see that singular mirror go trials (because they played in Hikaru no Go mirror go) are problem, because it is extremely boring, if you are going to do this in large and abusive scale. I once tried it against MFGo in even game, and I was shocked when I realized that I was behind about 6 points. All the efforts were ruined! –Jouni
There are ways to handle mane-go, which is a valid way to play. For instance, I have an sgf of a game between Cornel Burzo as W and a Euro 5d as B at h4 free placement. The Euro 5d made a ponnuki around k10 with his handi stones and then played mane-go. Cornel won the game. There is no reason to consider mane-go abusive.
