Renju of My Youth

Renju is played with black and white stones on a 15x15 board.

The rules are simple: be the first to get an unbroken row of five stones horizontally, vertically or diagonally. The first player (black) must avoid forbidden moves, while the white player can corner him into making one.

Here, we're playing the gentleman's way: all dangerous moves will blink as a warning, and forbidden moves are simply prevented. The game philosophy is to avoid low blows and to politely announce what's going on.
