I didn't invent this variant! See https://www.chessvariants.com/diffsetup.dir/argess.html. Note that this version is not guaranteed to be completely accurate to the rules given on chessvariants.com, but I believe the rules are essentially correctly represented as of the time of writing. The configuration code is from https://github.com/fairy-stockfish/Fairy-Stockfish/blob/master/src/variants.ini, where it is given as an example.

Reformed Courier-Spiel is a revised form of the Medieval Chess game Courier-Spiel. This version is a modern adaption by Clement Begnis which itself adapts H. G. Albers modernized rules from 1821. Detailed rules can be found on https://www.chessvariants.com/rules/reformedcourier-spiel and Begnis's http://clement.begnis.free.fr website. Note that the King castles to the C and K files and that three new pieces are added: Archer, Champion, and Paladin. The historical Courier moves as a modern Bishop, and to stay true to the original spirit of the game, it is shown by a wedge-shaped piece and not as the modern Bishop.

Created by EmyViv in May 2026. Similar to Seirawan Chess (also known as S-Chess or SHARPER Chess), with a slightly different starting board, and a gateable Cannon instead of a Hawk. The Elephant moves as in S-Chess, with the combined movement of a rook and knight. The Cannon moves as in Xiangqi; it can move without capturing as a rook, but must jump over another piece to capture the piece that it lands on. Cannons are placed on d1 and d8, and Queens start in hand.
