  | Align five stones in any direction.

p.
  At each turn, put a stone on the board, on any empty intersection.
  Once on the board, it will not move. The first player to align
  five stones (or more) in any direction wins the game.
  However, if White (playing in second) can achieve such an alignment right
  after Black, the game is a draw.
