  | Capture stones by approach or withdrawal.

p The following is summarized from Wikipedia.

p.
  The Fanorona board consists of 5 rows and 9 columns.
  A stone can only move to an adjacent intersection, following the lines.
  This movement can lead to captures.

h3 General rules

ul
  li Players alternate turns, starting with White.
  li There are two kinds of moves: non-capturing ("paika") and capturing.
  li.
    If at the beginning of a turn a capturing move is possible,
    then it has to be played.
  li
    | Capturing implies removing one or more pieces of the opponent, in one of
    | two ways:
    ul
      li.
        Approach — moving the capturing stone to a point adjacent to an
        opponent's stone, located right after in the movement's direction.
      li.
        Withdrawal — the capturing stone moves away from an opponent's
        stone, initially adjacent.
  li.
    When an opponent stone is captured, all opponent pieces in line beyond
    that stone (and connected to it) are captured as well.
    Another capture can then be achieved with the same stone.

h3 Some restrictions

ul
  li.
    An approach capture and a withdrawal capture cannot be made at the same
    time. The two locations will appear on the interface and you'll have
    to make a choice.
  li
    | The capturing piece is allowed to continue making successive captures,
    | with these restrictions:
    ul
      li The piece is not allowed to arrive at the same position twice.
      li.
        It is not permitted to capture twice consecutively in the same
        direction (first by withdrawal, and then by approach).
    | However, continuing the capturing sequence is optional.

p.
  The game ends when one player captures all stones of the opponent.
  If neither player can achieve this, then the game is a draw.
