If you’ve never heard of Huang Longshi, then… it’s not surprising at all. He lived in 17th century China and it was the Japanese players who ruled in the world of Go at the time. However his contemporaries described him as a heavenly spirit turned human, and Go Seigen, the greatest player of the 20th century, believed that Huang Longshi would be at least 13 dan if he were alive today! Is that merely an overstatement? Maybe the games of this ancient master reviewed under the magnifying lens of modern computer programs will help shed some light on this mystery…
In the free lesson “Treasure Chest” you will find all the games of Huang Longshi in SGF format, as well as the legendary collection of endgame problems “Yi Kuo” that has not been published anywhere before.
Suitable for: 8k–9d. This is a historical course, so it may be interesting to all players regardless of their strength.



A nice course that makes you feel connected to the old generation of players. However, I wish you had explained how they thought, why they chose certain moves, what they were known for, whether some moves were mistakes, and how AI evaluates them today. Many moves were shown without enough explanation, so I often didn’t understand why they were played. More context would make the course much better
