The original persian chess game from which modern chess evolved.
Shatranj is the game from which modern Standard Chess originated. Elephants take the place of Bishops, and the General replaces the Queen. Traditionally, the boards is not played on a checkered board.
Pawns cannot advance two squares on their first movement.
The General has very limited movement, and can only move diagonally one square.
Elephants move diagonally two squares, leaping the first square.
Pawns promote only to Generals.
Check and Checkmate rules remain the same as Standard Chess.
Stalemate results in a win, not a draw
Shatranj can be won by capturing all opponent pieces, so if the King is bare, it is win.
But, if on the next move, a capture can be made that results in both Kings being bare, then the game is a draw.
