Prompt
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.
Note: if ChatGPT makes an invalid move, try `Regenerate response`.
