Dieter's SGF-like codes

    Keywords: Joseki, SL description

Moved from Opening systematic classification


Dieter probably saying what has been said I have a good reason for desiring a classification. SL page names are becoming long if certain odd variations get their own page and if we want the page to describe what happens. I suggest the following:

All joseki start with the same color, say Black. Moves are notated algebraically, using the lower left corner. Following usual algebraic notation, x comes first then y. In order to get a horizontal representation, x is bigger than y the first time the diagonal is left after the first move.

As an example !B44W63B36W42B73 would describe the following diagram:

Clamp joseki

Black 1 being the last move in the page title.



Charles This kind of key sequence could be useful if included in the text of a page analysing subsequent variations. A few questions:

  • It is unique, but is it a suitable page title?
  • Is it suitable as a page alias?
  • Would it be better to introduce this kind of key somewhere on the page, so that it can be found by a text search?
  • (Not so important) It assumes no transpositions, so should those be handled by multiple keys?

Jan: I like Dieter's system, at least if it's used for page aliases. Transpositions could be aliased to the same page, or we could say that the keys describe move sequences instead of stone positions. I think the 'B's and 'W's are superfluous though, and tenuki needs a way of denoting too.

Dieter: Funny you say that in one "breath". The B's and the W's can precisely serve as the Tenuki notation.
