Check out Janggi (Korean Chess), our featured variant for December, 2024.

Chu Shogi

This page contains one or more presets for playing a game online with Game Courier, an online server for playing Chess variants by correspondence.

Chu Shogi is a historical large Shogi variant which was the dominant form of chess in Japan, until the introduction of piece drops caused it to be replaced by modern Shogi. Here is a selection of presets for playing Chu Shogi on Game Courier. Clicking on an image will take you to its corresponding preset. Each preset allows pieces to be moved with the mouse, asks what pieces should promote to, enforces the rules, and spots winning conditions. However, it will not notify you of check, checkmate, or stalemate, since there are no rules concerned with these conditions in Chu Shogi. The rules for repeated board positions are not enforced by the preset thanks to them being next to infinitely complex, so it is up to the players to abide by these. All the following presets use the same settings file and differ only in how they have been customized to use different boards. If you find any bugs in the routines used for enforcing the rules, please report them to Adam DeWitt.

Latin Pieces


Mnemonic Pieces


Alfaerie Pieces
