Invasions AND Reductions; Slate and Shell
BGJ 172 Summer 2015, Reviewer: Roger Huyshe
by Iwamoto Kaoru
Published in 2014, these two books are a rewrite of a single earlier book on the same subjects. They are presented as an encyclopedia of some 20 common formations, typically based on a corner with one or more extending stones. This encyclopedia approach put me off initially, but on reading a bit further I saw certain key points and tesuji being repeated and began to see some useful learning points.
There is no full board discussion in either of these books, but alternative lines are discussed, both from the point of view of reading and in relation to nearby stones.
