These tsume-go problems were published in the Dutch Go Magazine over the years. The editor, Cas Muller made tsume-go fun by introducing the articles with interesting pseudo-philosophical stories and commenting on the problems in a very entertaining way. Each magazine carries 10 problems while 6 issues are published every year. Expect the archive to fill up gradually... The problems in each set of 10 are usually increasingly difficult, starting at around 10 kyu and going to around 1 dan.
