Have you ever seen Chinese chess (xianggi pronounced shang ghee)? You've got red's side of the river and black's side. There's a river that runs across the chessboard. There's also a palace and no queen, just a couple of mandarins (guards). Less pawns and two cannons. The horse (our knight) moves in the same L-shape, but can be blocked by certain pieces. Some cannot make it across the river and the king cannot make it outside the palace. Pieces sit on the vertices of our squares, of which there are 9 across the board. More here:
