Initial motivation is to buy the "Middle-game" on the monthly course series, as it do cover the subject very different then traditional book. Since I saw other book in the series, so I purchase them together (joseki, tesuji, yose). And I buy another book by Jiang regard whole board stone disposition and the adequate move, as this subject seldom treat in the whole book as well.
