1	"""A live room (docs/games.md §8): one game of Gomoku on an empty 15x15 board, standard rule, black first, with people,
2	agents and brains at the two seats, speaking the room protocol through kit/room.py. A brain (a route's or a field
3	folder's, as in the checks) is told the whole position by BOARD before each move, 1 s a move; a seat on auto, a person
4	out of time and a brain that fails are played by the field's threats brain. At the end the game is left in replays/ in
5	the practice replays' format with a matches.json entry, so it lists as a match.
