11x 11 Board

11x11 diagram  

Sitting between the regular 9x9 and 13x13 formats, 11x11 is not a common format for go. However, it is an obvious way to play the game on a 10x10 checkerboard (the one used in international draughts). In any case, just by being within the range of standard square sizes, 11x11 can be set as the board size by many go playing programs.
