I was thinking today about the idea of a quick shorthand that would let a tournament player record their games with just a pen and paper, and not relying overmuch on board coordinates. Here are some ideas I had.
The code is written in move pairs, eg.
B1 ~ W1
B2 ~ W2
B3 ~ W3
The four quarters of the board are represented by a + and a dot. +’ (top right), +, (bottom right), ,+ (bottom left), '+ (top left.)
When disambiguation is needed, the leftmost move is marked with < and the rightmost with >; and the higher move with ’ and the lower with ,.
The corners are represented as H (hoshi), >K (right komoku), <K (left komoku), S (san-san), >T (right takamoku), <T (left takamoku).
An approach to the corner is =. An invasion of the corner is X.
A nobi (solid extension) is –; a one space jump is O; a two space jump is OO. A kosumi is /, a keima is Ø. Contact moves can be further marked by a C for disambiguation.
An extension can be described as E + the number of spaces it extends, and an ’ or , can be further used to indicate whether it is high or low.
So, let’s try to describe an opening.
1. +’ H ~ '+ H
2. +, >K ~ ,+ H
3. X ~ <–
4. – ~ –
5. Ø ~ E4,
6. = ~ Ø
7. E3’ ~ +, =,
And in long English
- Top right hoshi, top left hoshi
- Lower right kosumi (rightmost), lower left hoshi
- Invasion of the 3-3, inside block
- Nobi, nobi
- Keima, four-space extension (finishing the joseki)
- Approach to the lower left hoshi, keima away
- Three-space high extension, White approaches the lower right low.
