Commander Chess, or Cờ tư lệnh (literally 'Chess Command') is a xiangqi variant created by Hải Quý Nguyễn.

This is a 2-player abstract game with no luck

Cờ tư lệnh is played with 38 pieces (19 per player) on a board that is 11 lines wide and 12 lines long. As in xiangqi, it is played on the vertices of the grid. The board is divided into two territories divided by a river in the middle of the board. The three files on one side of the board form the sea. The object of the game is to capture the opponent's Commander, or all units of a single division of the opponent's army.

The Navy and Airforce can transport other units and all pieces may move and attack in the same turn.

Any piece that checks the opponents commander permanently gains heroic status and may move and attack further.

Anit-aircraft guns immediately defend against enemy aircraft and automatically shoot them down.

This game is combination of chess-like strategy mixed with a modern war game.
