I have just read the following via the BGA Go talk mailing list and thought it might interest some on OGS even if the link to Go is rather tenuous:
"I am sorry to learn that my friend and colleague John Conway has died of covid 19.
He was very distinguished, and made profound and original contributions to the theory
and practice of games.
He invented a game called
football’. It is played on a go ban, with one black stone, the football’,
and an unlimited number of white stones, the `players’.
The football is placed on tengen, and the two players each try to `kick’ the ball onto an
intersection on the opponent’s edge of the board.
A move consists of either placing a player on any unoccupied intersection or kicking the ball.
The ball is kickable if there is a consecutive string of players in a straight line, vertical, horizontal,
or diagonal, bounded by the football at one end and an empty intersection at the other.
The ball may then be kicked, passing over the heads of these players, who are then removed from
the board, and landing on this intersection. A player who kicks the ball may continue to kick it,
in the same turn, as long as it lands in a kickable position.
It is a subtle game. If you kick the ball forwards some players who were helping you by being ahead of the
ball are now helping the opponent. Various technical terms were invented, including being `poultered’.
It is a matter of bad shape. I forget the details.
Some people became rather good at the game; but I don’t know if it is still played. Give it a try."
