请给出一个中国象棋的算法代码

好的，以下是一个简单的中国象棋算法代码，实现了一个简单的随机走子AI：

import random

class Chessboard:
    def __init__(self):
        self.board = [
            ['車', '馬', '象', '士', '将', '士', '象', '馬', '車'],
            ['', '', '', '', '', '', '', '', ''],
            ['', '炮', '', '', '', '', '', '炮', ''],
            ['兵', '', '兵', '', '兵', '', '兵', '', '兵'],
            ['', '', '', '', '', '', '', '', ''],
            ['', '', '', '', '', '', '', '', ''],
            ['卒', '', '卒', '', '卒', '', '卒', '', '卒'],
            ['', '砲', '', '', '', '', '', '砲', ''],
            ['', '', '', '', '', '', '', '', ''],
            ['車', '馬', '相', '仕', '帅', '仕', '相', '馬', '車']
        ]

    def print_board(self):
        for row in self.board:
            print(' '.join(row))

        return random.choice(moves)

                moves.append((i, y))
                break
            moves.append((i, y))

                moves.append((i, y))
                break
            moves.append((i, y))

            moves.append((x, j))
        return moves

    def get_moves_for_knight(self, board, x, y):
        moves = []
