OGS Joseki Dictionary
OGS Hosts a "Joseki Dictionary"
Note that this feature is currently in "beta", available here.
The goal of the OGS Joseki Dictionary is to provide a well curated catalog of corner sequences of play that are credibly established to be among the best that you can do for the local situation (“joseki”), and mistakes and the refutations associated with those.
This should mean that if you play one of these joseki moves, and your opponent does not chose one from the sequence, then all other things being equal you would be better off.
The intended uses for the catalog are:
- Exploring known and established joseki
- Filtering out ones of less interest, by source, contributor and outcome
- Learning known and established joseki
- Ability to “play through” good sequences repeatedly, and at random
- Ability to play through mistake responses, to learn refutations
- Discussing the positions
- In-situ and “offline” (in the OGS forum)
- With contributors and known and respected Go players
The fundamental thing you want to do with a Joseki Dictionary is explore Joseki.
When you arrive at the OGS Joseki Dictionary, you are in "Explore" mode. The board is shown on the left side of the screen, and various information and tools are available on the right:
The most basic thing you can do is click on the board, just like playing, to explore the joseki variations.
As you click on a coloured position on the board, the information about that position will update on the right.
(You can also explore variations that are not in the dictionary by clicking wherever you like, but there will be no information about these exploratory positions that you try.)
Often you come to a Joseki dictionary looking for a sequence that meets your goal. Maybe you just want sente. Maybe you want a joseki that gives you influence into the centre.
You can use the "Filter" to help find these.
If you click on the "Filter" button in the "Extra Info" area (shown above) you are offered a list of "tags" to filter by:
You can pick one or more of these to limit the variations that the dictionary presents to you.
After you've filtered by at least one "tag", you can also filter by source and/or contributor.
You can find out what kinds of positions are available from the current position by opening the continuations details pane:
