A competitor in Chinese chess says he has sued the national association in China for mental distress after he was stripped of a title for drinking alcohol and defecating in the bathtub of his hotel room at a recent competition. Yan Chenglong doesn't deny what happened but wrote in a civil complaint this week that he drank a moderate amount of beer to celebrate his win with other players and that some food had caused stomach problems and he couldn't make it to the toilet in time. The complaint came one week after a social media post by the Chinese Xiangqi Association that described the drinking and defecation.
