I used to play igo on Nihonkiin website. Sometimes I wage reckless attack to capture the land before cementing my own ground. At that time I am counterattacked and fully destroyed. I must plan a strategy. So I read two Igo manual books, Chikun Cho ‘Kabe Seme no Gokui” and Masaaki Fukui ‘Meikai! Jyoseki jiten.” The shobu is almost at its best.
