Let's play chess. The goal of the game is to checkmate your opponent's king. Print the board (with ABCDEFGHI/12345678 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 on top of other moves. Do not modify the original board before a move. Now make the first move.
