Korean Problem Academy: a copyrighted collection of 750 problems from the Korean baduk schools designed to train young kids to become dan level players. The problems are divided into 4 sets:
The problems seems to come in sets that focus on a single concept: createing false eyes, death in the hane, descent to kill, creating big eyes, etc.
The first set of problems (25 kyu - 15 kyu) focus on the concept of a live group via making two eyes and killing groups by creating dead shapes with them.
The focus of the second set (15 kyu - 5 kyu) is ...
The third set (5 kyu - 1 dan) focuses on ...
The fourth set (1 kyu - 4 dan) drill ....
The problems are accessible online at GoBase (free
registration and login required).
Erratum for the solutions on GoBase
The collection is copyright Pierre Audouard (audouard.pierre@wanadoo.fr), who provided solutions to all 750 problems.
Velobici: Regarding this copyright issue, I have a difficulty understanding what Pierre's copyright covers. Does the copyright cover the problems or just the solutions? The problems were not composed by Pierre. Pierre has added solutions and, perhaps, created the SGF files. It would seem that Pierre's copyright covers the solutions only. By way of analogy, if a person publishes a commentary on a work and copyrights it, the copyright covers the commentary only. The status of the preexisting work is unchanged.
adammarquis: Does anybody think the ranks a bit overestimated? I am around 7-8 kyu and the 3rd set of problems are rather quickly and easily solved.
jfc: I never give much credit to problem rankings. The relative problem difficulties are of some use but difficulty is very subjective.
It it not clear who assigned these rankings. Did the original Korean Publications?
Lastly, the original books simply list the starting positions without solutions. Not providing solutions makes it feel more like a real game position. In a game every problem is a status problem and it is important to know not only whether a group is alive or dead but things like how many ko threats does black have here and what aji is left behind by the dead group (e.g. sente peeps). I agree that as problems the positions are easy for the rank specified. As life and death positions to study I think they are very interesting.
nachtrabe: I just heard Janice Kim on a KGS Plus lecture say that the "right level of problems" for L&D practice is the kind of problem you can solve "instantly." Perhaps these problems should not be viewed as "problems that someone at that level can do" so much as "problems that someone at that level should practice"?
WilliamNewman: Does anyone know the Korean title of this publication? I was thinking of asking a Korean friend to try to find at least one of the original volumes (in hopes of reading it as I can read Maeda's problems without speaking Japanese). I expect it would be easier to find if we had the Korean title, not just an English paraphrase of the title. (Insert grumpiness here about someone who not only seems to ignore original copyright while asserting his own unqualified copyright -- copyright protection for me but not for thee -- but also doesn't follow the usual academic or net-public-domain-software courtesies of clearly citing the original. Still, I must admit that admitting that there was an original is an important step up from some of the behavior that I've seen.)

Velirun: Hey all - I import Korean baduk books for American players, and I've now had well over a dozen requests for these books. I'd love to find some copies for the masses, but even with these ISBNs I can't seem to find them. If anyone has any more information about these, anything at all, could you please post it here?
