The first in a series of books on the playing styles of top pros by Yuan Zhou. This series is aimed at helping amateurs to understand what it means to have a consistent style of play and to develop their own. In this book, Zhou uses a very thorough analysis of two of Lee Changho's games to clarify why Lee's style is called "calm and solid" and why it is so effective. Diagrams in the book typically contain only one or two new moves so it is easy to follow Zhou's analysis.
