Huang Longshi (Trad. CHN: 黃龍士, Simp. CHN: 黄龙士, JPN: 黄龍士 (こう りゅうし), a.k.a. Huang Yuetian & Longshi, the Prodigy, 1651/54 - ca. 1700) was a go player in the Kangxi period of the Qing dynasty in China.
Longshi was born in the district of Jiangyan, near or in the city of Taizhou, in modern day Jiangsu Province, an area of coastal eastern China south of Beijing and north of Shanghai. He became guoshou at age 16, one of the fourteen sages of ancient China by his contemporaries, and subsequently praised as one of the most accomplished go players of all time.
Longshi is known for his contribution to the use of influence and thickness by learning how to force his opponent into inefficient or over-concentrated shape. This has led some commentators to suggest a parallel development of tewari analysis alongside Honinbo Dosaku, though at a less rigorous level. He was a very strong fighter -- mastering the art of amarigatachi strategy and building territory while attacking on a global scale. His games are also noted for their frequent inclusion of myoshus (excellent moves) and surprising tesujis.
Longshi was responsible for many famous games, the most famous being the Games of Blood and Tears against Xu Xingyou. Other notable games are against friend and rival Zhou Donghou; and against the old master Sheng Dayou.
Famous book publisher Deng Yuanhui said:
Longshi used his mind most meticulously. He sought to enter the deepest apertures. When it became a critical matter of life and death, and while the crowd were already helpless and at their wits' end, he was expertly exerting a subtle influence, and seeing more and more skilfull ideas and magical effects; the air would suddenly change... and from death he would re-enter life.
Longshi is like a heavenly spirit turned human. He is absolutely not of this world.
Huang Longshi also composed a work called the Yi Kuo, the first part of which contains 30 kifu from the fuseki and into the middle game, and the second part is a tsumego collection of 361 problems. It was published after his death, in 1710.
A modern international female team tournament, Huang Longshi Shuang Deng Cup is named after him.
