Now you can see for yourself. The sequences in this book are considerd "haengma" by Korean professionals. This book is intended for dan-level players. A number of wholeboard positions, mostly from recent professional games, are analized. In all of these cases the game is at a critical moment, a sequence has to be found to resolve a problem like breaking out or gain control of the situation. In allmost all sequences in this book there is a tesuji, and after the haengma is carried out you have good shape, and some actions are sabaki. After stuying this book I would tend to translate haengma as "action".
