Cylindrical Chess Presets for Game Courier
Here are two presets for playing Cylindrical Chess. These were made in 2021 by Fergus Duniho, and they use logical directions instead of mathematical directions. One is for playing on a normal chessboard, and the other is for playing on a circular board. Both these presets will enforce legal piece movement and spot check, checkmate, and stalemate. Click on either image to go to the corresponding preset.
Antoine Fourrière previously wrote presets that used mathematical directions. If you're interested in the difference between logical and mathematical directions, it would be worthwhile to compare Fergus Duniho's new presets with Antoine Fourrière's old ones. Here are links without the graphic images:
