yuuryoku

Yuuryoku is a Japanese word meaning having power or strength, powerful or effective. It is very often used in professional go commentaries, while it is almost absent in the Western amateur go vocabulary.[1] It may be used as an evaluative term, to describe the way in which fighting is conducted, perhaps muscular.
