The first Batoo book!
The first book about Batoo by professional player Yang Gun, 8p was published few days ago.
The title is "양건의 바투레벨업", which means "Batoo Level Up with Yang Gun".
The price is 12.000 won or near $10, but I don't know how to order it online.
The best way is to ask Alexandra Urban at her Baduk books webshop:http://badukbooks.blogspot.com/
Maybe she can help.
