Josekis View attachment 1682469
I've been (re)learning the game of Go, which is very popular in Japan. Many books on the game use Japanese terminology, and one book I just finished had a chapter introducing Josekis. There are volumes of books on these "common" moves.
Unlike Chess, where there are a limited number of moves in the opening game, with a 19x19 Go board, the number of stone placements possible are astronomical, so over the years people have formed these Josekis as a framework for some of the early game stages (and even in middle game). There still is quite a variation that can arise, but learning some of these along with intuition can help in game play.
Yeah, me neither, when I played as a teen. I only knew the basic terms like atari and ko, but now I'm reading about all sorts of Japanese terms for things. Some are specific types of plays, like "hane" and "hasami", and others are more general, like "joseki", "fuseki", and "yose".
