说明：  进行blocus游戏代码。游戏开始时，你要把己方颜色的棋子从棋盘起点处依次摆放到棋盘上，每个棋子只能与同色棋子的棋角相连，不允许沿棋边贴着摆放。
(For blocus game code. The beginning of the game, you take one' s own color pawn from the board at the beginning of turn placed on the chessboard, each piece can only be connected to the chess corner pieces with the same color, is not allowed to move along the side close to the placement.)
