coordinates
Coordinates are used to name every point on the go board, e. g. in a game record or simply to describe stones on the board. Several styles are in use.
- Style A1
In Europe it is usual to give coordinates in the form of A1 to T19. Where A1 is in the lower left corner and T19 in the upper right corner (from black's view). Note: "I" is not used, historically to avoid confusion with "J"
- Style 1-1 or 一1
But there are also other coordinate notations in use. E. g. in the form of two figures 1-1 to 19-19. In written one of the two coordinate usually is given in kanji.
Note that 1-1 is at the upper left corner and 19-19 at the lower right corner.
For an example see this game record:
- Audouard coordinates
See also Audouard coordinates for a different coordinate system more suited to Go.
Just in case you were having trouble memorizing coordinate equivalents by point name.
