AI Evidence: Finding
On 2024-12-15, Chinese professional Qin Siyue (2-dan, born 2006) was caught cheating during round 9 of the women's division of the 2024 National Weiqi Championship (Individual) in Shenzhen. A referee's routine in-game check found her with a phone running an AI program. The event is run by the Chinese Weiqi Association and had 242 professional players. She was given a loss for the game and suspended during the investigation. On 2025-02-26 the Association's Discipline and Ethics Committee revoked her professional rank, cancelled her 2024 results, and banned her from all Association events for 8 years. The Association cited venue video showing she entered the venue in the early morning to hide the phone, and Xinhua reports she admitted cheating at a hearing. This meets every part of the criteria: a Chinese pro, in-person over-the-board cheating, an official pro tournament organized by a pro organization, and all three listed penalties. The incident and the ruling both fall between market creation (2024-02-26) and the deadline.
