Piece Movement Reference
King (将/帅): Moves one step in a straight line within the palace (3×3 grid). Cannot leave the palace. A critical rule is the "Flying General" — the two kings cannot face each other on the same file with no pieces between them. The player who creates this face-off wins immediately because they have effectively captured the opponent's king on the next move.
Advisor (士/仕): Moves one step diagonally within the palace. The advisor has only 5 reachable intersections — the four corners of the palace plus its center. It acts as the king's personal bodyguard. Elephant (象/相): Moves exactly 2 squares diagonally (like a "field" character 田), always staying on its own side of the river. Crucially, if there is a piece at the center of that 2×2 diagonal block (the "elephant's eye"), the elephant cannot move there. This blocking rule is the most common elephant-related mistake.
Horse (马): Moves in an L-shape — one step straight then one step diagonally — similar to an international chess knight. The critical difference: the horse CAN be blocked. If a piece is adjacent to the horse along the straight part of the L, the horse cannot move in that direction. This is called "blocking the horse's leg." Rook (车): Moves any distance in a straight line, cannot jump. The rook is the most powerful attacking piece in Chinese chess. Cannon (炮): Moves any distance in a straight line, but TO CAPTURE it must jump over exactly one piece (the "cannon screen" or "mount"). Without a screen, the cannon can only move, not capture. Pawn (兵/卒): Before crossing the river, can only move forward one step. After crossing, it can move forward, left, or right one step. Pawns never promote and never move backward.
