It was a really nice introduction with different ways of teaching, going from small-board example games to tactics, common jousekis and openings, to discussing a full-board game (Kitani v. Seigen, 1940). What I especially liked as a beginner was the last part where different strategies for handicap games were outlined, some for each level of handicap.
Might read again before I move on to non-introductory texts, even.
