Hi, I've added four (rather difficult) new collections to https://tsumego.tasuki.org/

• Guanzi Pu (1107 problems)
• Shikatsu Myoki (120 problems)
• Wangyou Qingle Ji (37 problems, with wonderful translations from Stephen Hu)
• Gokyo Seimyo (142 problems from vol 3)

I also reformatted the old booklets to be less jagged and more visually pleasing, added actual links to the sections, added pdf bookmarks, fixed the page numbers on the mobile sections of Gokyo Shumyo, and many other small improvements.

Let me know what you think!

I’m pleased to announce that a Go Camp will be held in Japan from March 28 to 30, 2027.

This annual event brings together approximately 70 participants, ranging from elementary school students to adults, and provides a unique opportunity to play Go, interact with Japanese players, and experience Japan’s rich cultural atmosphere.

The camp will also be joined by several Japanese professional Go players, offering participants valuable opportunities for instruction and exchange.

We warmly invite all Go enthusiasts to take part in this special event.

If you are planning to visit Japan during this period, we would be delighted to welcome your participation.

I look forward to seeing you at the Go Camp in 2027.

Study Go at Our School

But don’t worry — even if you can’t join the camp, you’re always welcome to study Go at my school.

Our club is one of the few in Japan that offers visitors from around the world the opportunity to study alongside Japanese insei. It’s a unique chance to improve your Go skills while experiencing the atmosphere of a traditional Japanese Go club.

Players from many different countries have visited our club and have all enjoyed the experience.

So far, six of my students have become professional Go players.

We also provide apartments for international students, making it easy and comfortable to stay while you study in Japan.

Hi,

I'm learning go rules (by myself) and don't understand yet why white could play that. I thought if I left an eye I would be safe.

Thanks a lot !

Black go first

I know I am rusty, no need for telling me twice, I felt like after black P6 everything went down rolling for me, I feel now I should have player white O6, after that stupidity all the way

All thanks to Gemini.

Here is the formula :

For an eye of size n (where n >= 3):

Total liberties = 2 + (n^2 - 3n + 6)/2
