[1] Bill: Isn't tsume more general, a kind of approach that is not an invasion, nor a kakari, nor a yose? I suppose that, in practice, such a move will nearly always be an extension, as well.

Charles I learned the term tsume from old magazine articles of Takagawa, many years ago - and then forgot it, because I never could quite understand the definition. So what Bill says is probably much like what I found unmemorable ...

John F. Bill's doubts are justified and this page is built on a false premise, really. A tsume is a move that blocks the sideways development of an opposing group. Of itself it says nothing about extending, though, as Bill says, in practice it will often double up as one. But "checking extension" emphasises extension, whereas tsume emphasises blocking. The terms hirakizume and tsumebiraki also exist; the latter is a checking extension. Tsume as in tsumego/tsumemono means abbreviated, packed in. Tsumeru as in dame wo tsumeru means fill in liberties.

Charles So, it does seem that tsume should be discussed on a separate page, anyway. I've gone back to the Takagawa article and clearly I still don't take the point: see tsume discussion.
