SGN

    Keywords: Software

Smart Game Notation(SGN) is a file format for saving positions. Its main purpose is to allow making problem collections.

Syntax

Notation starts with the top row and goes from left to right. Forward slash '/' is put at the end of each row but a hyphen '-' is used at the end of last row. If there isn't any stone on a row then nothing is written for that row except the forward slash '/'.

  • Black stones: Lower case 'b' if there is only 1 black stone, upper case 'B' + the number of consecutive black stones if there is more than 1 black stone consecutively. For example, 'B-5'(with no hyphen) for 5 black stones in a row.
  • White stones: Lower case 'w' if there is only 1 white stone, upper case 'W' + the number of consecutive white stones if there is more than 1 white stone consecutively. For example, 'W-5'(with no hyphen) for 5 white stones in a row.
  • Empty points: The number of empty points consecutively. For example '5' for 5 empty points in a row. No letter is necessary for indicating empty points.
  • The point of KO: Upper case 'K'.
  • Side to play: This is written after all the board information is given. Upper case 'B' for black to play or 'W' for white to play.

Examples

In this example it is black's turn to move so there is 'B' after the hyphen. Notice that the notation starts with forward slash '/' in this case. This is because there isn't any stone in the first row.
