Word Builder (Bob Jackman)

Bob Jackman is a veteran Scrabble player from Australia (National Champion). When I bought this book from him, he told me that he made the list for people whose first language was not English. I remember buying from Hirai san four Scrabble booklets made by Bob Jackman, before winning my first Scrabble National Championship here in Japan. This book is a compilation of those booklets. I bought it last year for 30 dollars and selling it for 1000 yen.
