Chen Zude (simplified Chinese: 陈祖德; traditional Chinese: 陳祖德; pinyin: Chén Zǔdé; February 19, 1944 – November 1, 2012) was a Chinese professional Go player.
Although, according to Kato Masao, this pattern originated in Japan, Chen was the person who made this fuseki famous.
Yasunaga Hajime, a Japanese pro-level amateur and teacher of many professionals, claims in his books that Chen saw the fuseki first when attending a study group and exhibition matches organized by Yasunaga and held in China.
Zude was President of the Zhongguo Qiyuan and also served in the Chinese Weiqi Association from 1992 - 2003 as chairman.
Zude was the first Chinese Go player in the modern era to attain the rank of 9-dan.
