Strategic Concepts of Go, by Nagahara Yoshiaki, published by Ishi Press in 1972 was a ground-breaking introduction to some higher-level thinking in go, and its terminology. The book begins with an exposition of eight named strategic concepts (miai, aji, kikashi, thickness, korigatachi, sabaki, furikawari, and yosu-miru). This exposition of eight chapters and sixty pages comprises a crash course in how stronger players think about the game.

The exposition is followed by a stimulating set of 72 problems, presumably from author Nagahara Yoshiaki's own teaching; most of these are dan-level problems.
