  | Bishops and queen are less powerful then in standard chess.

ul
  li Elephants replace the orthodox bishops.
  li General or vizir replace the orthodox queen.
  li The only special pawn move is the promotion, always to a vizir.
  li There is no castling option.
  li.
    Stalemate or bare king counts as a win, but two bare kings count as a draw.

  | I implemented a slightly different version of Shatranj
  | as described for example 
  a(href="https://www.chessvariants.com/historic.dir/shatranj.html")
    | on chessvariants.com
  | , because otherwise elephants could only evolve on a quarter of the board,
  | and the vizirs would be colorbound as well as the promoted pawns.

  So, while trying to keep the feeling of this old game,
  here is what I came up with:
ul
  li.
    Elephants can move by one or two squares diagonally.
    Only the 2-squares moves (maybe jumping over a piece) can capture.
  li.
    Generals can move (without capturing) to any adjacent square
    horizontally or vertically.
    They capture on any diagonally adjacent square, so that a general
    corresponds to a natural pawn promotion.
p All other pieces move like in orthodoxe chess.
