Chess on a 12 by 12 board Doug Vogel wrote in December 2000 on the chess variant, where one plays with the same pieces but on a board with a bigger size. While the idea might not be new, I cannot recall having seen it. Rules Chess is played on a 12 by 12 board, with the usual setup of chess pieces in the middle 8 by 8 part, i.e., the 8x8 grid is positioned centered within the 12x12 grid.
All rules stay the same as in usual chess .
Pawns much reach the 10th row to promote, i.e., the last row of the 8 by 8 board. See also Ralph Betza's Chess on a Really Big Board . If you have Zillions of Games installed, you can download this game and play it. Zillions implementation by Peter Aronson. Written by Hans Bodlaender, based upon email of Doug Vogel.
