Board geography
Keywords: Theory, Go term
When discussing moves[1]:
- Up = towards the center
- Down = towards the edge
Areas
The board is loosely (third/fourth/fifth line can be the border between them) divided into nine areas:
- division
- Four corners
- Four sides[1]
- The center
- abbreviations
- UL: upper left (corner or quarter)
- TL: top left
- UR: upper right
- TR: top right
- LL: lower left
- BL: bottom left
- LR: lower right
- BR: bottom right
- US: upper side
- LS: lower side or left side (hence to be avoided)
- RS: right side
Spots
When discussing theory most people use relative coordinates most of the time.
- Relative coordinates have the form x-y, x and y both ranging from 1 to 10. The first point discussed has the smallest number first. So 3-5 point, not 5-3 point.
- Absolute coordinates. A1 is the left closest corner point for black. T19 right farthest. Absolute coordinates have the form x99, where
- x = Horizontal, a roman character A through T, I is skipped.
- 99 = Vertical, one of the numbers 1 .. 19
- Named points

*
- (Strict:) Starpoint = Hoshi = one of the nine marked points on the board
- Tengen = the marked point in the center of the board
- Hoshi without qualification is used for one of the four 4-4 points[01]
- Starpoint without qualification is used for one of the four 4-10 points
- Sansan even means 3-3
- Twenty four other intersections - two of each of the following three in every corner - have their own, non-systematic names:
- komoku = 3-4 point
- mokuhazushi = 3-5 point
- takamoku = 4-5 point
- ... [02]
Height
- very low = second line (not first)
- no qualification = low = third line
- high = fourth line
- very high = fifth (not sixth)
Distance[2], [3]
- contact = no space
- no qualification = close (approach) = small (enclosure) = one-space
- distant (approach) = large (enclosure) = two-space
- very distant = three-space
- pseudo = four spaces (or more?)
footnotes
[1] The upper side is the side closest to white as are the upper corners.
[2] The number of spaces refers to the horizontal distance, not the Manhattan distance. The Manhattan distance is used when talking about pace and the strength of connections.
[3] See also Joseki nomenclature - expert names
temporary comments & discussion (to be removed when resolved)
[01] Is this Japlish?
[02] Both the 2-2 point and 1-2 point have a very special role. Why don't they have a name of their own? Or do they? -- mAsterdam
