Brett und Stein Verlag 500 Go Problems: Are you ready for Brown? 3 Kyu - 1 Kyu

The game of Go is, occasionally, referred to as a sitting martial art. This series of books is dedicated to kyu ranked players and uses the following colors to represent belt colors often used in martial arts rating systems: white (beginner), yellow, orange, green, blue and then brown. The brown color stands for the power of the mountains. For the student, it is time to deal with the vastness, the sky, to become more attuned to the ascent to mastery. These final kyu grades are probably the most difficult. The goal seems close, but reaching it requires more refinement and further coordination of technique and strategy. This books can be used as a classroom tutorial, as an after-school exercise, or as a test for self-learners who would like to improve their skills.
