This tool is an analyzer for board positions in the game of Go. It can be used to analyze positions on standard boards (19×19, 13×13, 9×9) as well as non-standard boards. The non-standard boards can be rectangular boards of unconventional sizes (5×13, 19×2, etc) or non-rectangular boards. The program comes packaged with a dozen preset board types, and a graphical tool you can use to design your own. Analyses are saved in files with the .san extension and can be opened again later.
