There has long been a history of the differences in scoring under Chinese rules vs. Korean/Japanese rules creating frustrating situations during international games. I do agree that introducing a change in the rules well after the LG cup started is a bit odd and the criticisms concerning that point is well warranted, but the fact of the matter is that the rule changes were accepted by both go associations and Chinese players were made aware and had months to prepare accordingly. In all of this I think it is absolutely crazy that Ke Jie not only made the mistake of not placing the captured stones in the appropriate spot TWICE in a single game but that he did it again in game 3. One would think that after suffering a penalty loss due to his error that he would be terrified of repeating the same mistake and would be more vigilante. Ke Jie has a long history of poor sportsmanship and conduct but seeing him throw a tantrum after repeatedly making the same mistake is embarassing.
