Lee Changho ( according to Go Game Guru) at 16 years, 5 months and 29 days
Not Fan Tingyu at 16 years and 7 months
To clarify the apparent confusion, Go Game Guru explains here that age is counted starting from 1 at birth in Korean culture, so even though it's usually said that Lee Changho was 17 when he won the 3rd Tongyang Securities Cup, he was actually only 16 by the Western reckoning of age. This means that Lee Changho still holds this record.
