Cannon Fire and Palace Walls: How Xiangqi Diverged from Its Chess Cousins

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Every game in the chess family shares a king figure to be trapped, but Xiangqi builds the whole board around protecting its general instead. The general is confined to a three by three palace and may never leave it, may never face the enemy general down an open file with nothing between them, and is defended by two advisors who are themselves confined to the same small square. Nothing in Western chess, Shogi or Janggi imposes a matching cage on the king, which makes Xiangqi endgames read differently from the moment the general appears on the board.

The cannon compounds the difference. It moves like a rook along ranks and files but can only capture by jumping exactly one piece, friend or foe, to land on its target, a move with no equivalent anywhere else in the chess family. Combined with the river dividing the board in half, which certain pieces may never cross, Xiangqi ends up feeling less like a variant of chess and more like a related but independently engineered game that happens to share the aim of checkmate.
