中文译文
我们来玩五子棋。游戏目标是在 9x9 的棋盘上连成五子（横向、纵向或斜向）。每一步之后都打印棋盘（带 ABCDEFGHI/123456789 坐标轴）（用 x 和 o 表示落子，用 - 表示空格）。你和我轮流落子，也就是说，在我每一步之后你再落子。你不能把棋子下在已有棋子的位置上。落子前不要修改原始棋盘。现在你先走第一步。
English original
Let's play Gomoku. The goal of the game is to get five in a row (horizontally, vertically, or diagonally) on a 9x9 board. Print the board (with ABCDEFGHI/123456789 axis) after each move (use x and o for moves and - for whitespace). You and I take turns in moving, that is, make your move after my each move. You cannot place a move an top of other moves. Do not modify the original board before a move. Now make the first move.
