Matching

Match Joseki

In a fraction of a second, SmartGo can match a given position against all the positions in all the games in the library of professional games.

SmartGo can match positions on the whole board (fuseki) or in a corner (joseki). You are not bound to a fixed pattern size: You can change the area for matching to include additional points or exclude irrelevant points, and SmartGo will update the search results immediately.

You can turn on SmartGo's matching by choosing Tools > Joseki Matching. SmartGo will show the next moves that professionals have played on the board.

This is much more powerful than a joseki dictionary:

  • Professional moves: Its shows moves that professionals actually played in serious games.
  • Game context: It shows you the context the professionals played those moves in.
  • Follow-up moves: It shows you the follow-up after the joseki: what happens after the joseki is played?
  • Up-to-date: Just add recently played games to the library, and SmartGo will include the newest joseki moves.

Joseki Context

Turn on Joseki Context to get an idea of the typical surrounding position for a certain joseki. SmartGo uses light and dark shading to indicate where white and black stones are most often located along the relevant edges.

Joseki context along edges

You can also sort moves by context to get a better idea of which next moves might best match the current position. Compare the two positions below: on the left the moves are sorted by frequency, on the right moves are sorted by how well SmartGo thinks a move matches the surroundings.
