Symbols
In Go literature, diagrams are almost always adorned with a few special symbols (markup) such as triangles, alphanumerics etc. This page intends to act as a reference as to when and how to use symbols.
Until now, the use of symbols has been fairly intuitive; re-using symbols for other ends would not give major problems, although some kind of convention already exist.
The material here is a mere condensation of information found on RGG as well as other sources. (Please use the discussion page for comments.)
Symbols in ASCII diagrams: ASCII markup
'.'
- intersection on the goban
'|', '+', '-'
',' '+'
'O'
'#', 'X'
digit (1..9)
- sequence of moves (make sure to state which side is using the odd numbers)
- the compact nature of ASCII diagrams requires to limit to singl-e digit move numbers; use more diagrams to show longer play sequences.
letter
Symbols used by applications: SGF/print markup
Following symbols have existed for a while.
Number, digit ( , ...)
Letter
- used on empty intersections to show moves in a variation. Japanese go materials would commonly use hiragana or katakana (often in the "i-ro-ha" order).
Triangle
- mark a formation/point that is being talked about
Circle ( , )
- highlight the last move (mainly used in applications, less in diagrams)
- a stone breaking the ladder, a group in danger
Open square ( , )
- cGoban2 uses a square to denote a ko
Cross
- counting: territory
- mark dead stones
Other symbols
Following symbols are mostly used by applications, but generally not stored in game records.
Filled square
- used by some applications to denote the status of an intersection (black, white, Dame, undetermined)
shading, dimmed points
New symbols, concepts
Following symbols could become part of the existing set of widely recognised symbols. See discussion page for status.
- Arrow
- Line
- Diamond
- '!'
- '?'
- blinking or pulsing
- Igowalker has the ability to pulse stones to emphasize them. This allows the stone to be identified even if it already has a number on it.
