Waltheri's go pattern search
Waltheri’s go pattern search is an online game database for searching professional (including AlphaGo) games for go patterns and positions. Its source code is available on GitHub.
The 79,815-game database hasn't been updated with any games dated after 11 March 2020. Unfortunately this means that Waltheri is gradually becoming out of date for research on the most current joseki, like the flying knife.
There are 3 modes for selecting positions.
- Fuseki - full board search, browsing through game positions by frequency.
- Joseki - searching the area around a position set up by the user
- Manual - both the position and the search area are set up by the user
Games can also be searched for by player(s) and date.
