The Chess Variant Pages



This page is written by the game's inventor, Adam DeWitt. This game is a favorite of its inventor.

Yangsi

When I first stumbled upon the Chess Variant Pages back in 2016, it was due to an image of a large chess variant I encountered while looking at images of chess variants. The image I found was a picture of Fergus Duniho's Gross Chess, an expanded version of chess played on a 12x12 board with a wider assortment of pieces. Shortly after that, my interest in the site started to grow, as did my interest in chess variants in general. I also started to invent my own chess variants. I started by placing the 12 different pieces from Gross Chess onto a 10x10 board and making a few small changes to the rules to make the game more similar to FIDE Chess, giving birth to the game of Yangsi.

Setup

An interactive diagram has been provided (The Javascript source code was written by H. G. Muller) to make it easier to understand how each piece moves. The diagram uses pieces from the Musketeer Chess Board Painter.

First rank

Third rank

M/m = Marshall, A/a = Archbishop, V/v = Vao, W/w = Wizard, C/c = Cannon,
R/r = Rook, S/s = Champion, N/n = Knight, B/b = Bishop, Q/q = Queen, K/k = King, P/p = Pawn

Pieces


King
The King moves one space in any direction but not into check. It moves the same as it does in Chess but castles differently.
Queen
The Queen moves as a Rook or a Bishop, the same as it does in Chess.

Marshall
The Marshall moves as a Rook or a Knight. It is a popular piece in many Chess variants, dating back centuries, even before Chess as we know it today came into existence.
Archbishop
The Archbishop moves as a Knight or a Bishop. It is a popular piece in many Chess variants, dating back centuries, even before Chess as we know it today came into existence.

Rook
The Rook slides across the board in a vertical or horizontal direction, as it does in Chess.
Bishop
The Bishop slides across the board in any diagonal direction, as it does in Chess.

Knight
The Knight leaps to a space one file and two ranks away or two files and one rank away, as it does in Chess.
Pawn
The Pawn moves one space vertically forward without capturing, and it moves one space diagonally forward to capture, as it does in Chess. It can also move two squares forward on its first move and capture by en passant a Pawn that has just made a double move like it does in Chess. However, it is subject to different rules of promotion.

Champion
The Champion leaps two spaces in any orthogonal or diagonal direction, or one space in any orthogonal direction. It is a compound of the Alfil, Dababbah, and Wazir. It was introduced in Omega Chess, and it moves the same as it does in that game.
Wizard
The Wizard moves one space diagonally or leaps to a space one file and three ranks away or three files and one rank away. It is a compound of the Ferz and the Camel. It was introduced in Omega Chess, and it moves the same as it does in that game.

Cannon
The Cannon moves as a Rook but must hop over an intervening piece to capture. This piece comes from Chinese Chess and moves the same as it does in that game.
Vao
The Vao moves as a Bishop but must hop over an intervening piece to capture. It was created in the early 20th century as the diagonal counterpart to the Cannon.

Rules

Aside from differences in the board, pieces, and setup, Yangsi is played like FIDE Chess with the following differences:

Pawn promotion: When a Pawn reaches the last rank, it must promote to another piece of that player's choice: a Queen, Marshall, Archbishop, Rook, Champion, Cannon, Knight, Bishop, Vao, or Wizard of the same color. It cannot promote to King or another Pawn.

Castling: When castling, a King may move two or three spaces toward the Rook when it castles, with the Rook leaping over the King to the closest space the King has just passed over, so that King and Rook end up adjacent to each other. The usual castling conditions from Chess apply. A King may not castle from or through check, all spaces between the Rook and King must be empty, and neither piece may have moved before.

64-move rule: The 50-move rule from Chess becomes a 64-move rule in Yangsi. Similarly, the lesser-known 75-move rule from Chess is a 96-move rule in Yangsi.
