Ways to Create or Edit a Game Record | Tools | Options | Error Messages when Loading a Game File | Related Links

Ways to create or edit a game record:

* Offline create or edit an sgf-file from your harddisk
* Online create a game record by setting up a demo game
* Play a teaching game, stop game for discussing moves and variations and later play on
* Upload an sgf-file to KGS for a demo game
* Review a game with your opponent or observers after the game has ended or load it from a player's games list for review
* Clone an ongoing game from the game window to try out and discuss, without disturbing players and observers (later moves from the game become added to the game tree)
* View an ongoing game offline (later moves do not become added)


Move (F1): ctrl-shift-click on the board changes actual colour
Edit (F2) (crosscut-icon): Set up a position, shift-click for white stones
Score (F3) (yinyang-icon): mark territory (only for exactly fenced in territory) click on stones to mark as dead, shift-click to unmark from dead; unmark territory with ctrl-shift-click on one marker
Markers (F4-F6): triangle, square, circle
Labels (F7): A...Z as sequence, free labels with shift-click (abc, 123, !, %, ?,...) restrict yourself to 2 characters per label
Number (F8): 1-80 as sequence, move number with shift-click
(online:) give (ctrl-g) / take (ctrl-t) editing control, set players

Error Messages when Loading a Game File

If the game result has been written with another program, CGoban may display an error message, when the result doesn't have a fixed format. It is likely that the "errors" will not hamper the display of the file by CGoban. Here are examples of typical error messages.

Shown by a text editor (sgf is a text-only format):

RE[W+0.50] (is o.k., but not RE[W+0,5], not RE[W + 0.5], not RE[White+0.5])
RE[W+resign] (o.k.)
RE[?] (is o.k., but not RE[unknown])
RE[0] (is o.k., but not RE[jigo])
RE[void], RE[no result] ( both o.k.)
RE[W+Forfeit] (o.k.)
RE[W+Time] (o.k.)
