This 468 page book is one of the earliest examples of programmed instruction popular in the 1970s and subsequently. It is probably the rarest of international Master Edward Lasker’s books on chess. Edward Lasker was a distant relative of the second world champion Emanuel Lasker. This book is in excellent unread condition. I think this is one of the most vastly underrated instructional books on chess. The only reason I am selling it is because I have a signed hardcover edition. The original price was $13.99.
