Yuan Zhou
This book will have a revolutionary impact on any kyu player who reads it. Zhou clarifies the common kyu level misunderstandings of how to play which hold kyu players back from reaching dan level. He explains that the skills needed to reach shodan are not things like a thorough knowledge of josekis or an ability to read out long sequences, but rather the elimination of some common confusions about how the game should be approached. The principles involved are not difficult to understand and Zhou clarifies them by giving detailed analyses of how they are being ignored in three different games between kyu level players.
