Hiashatar is a medieval chess variant played in Mongolia. The game is played on a 10×10 board. The pieces are the same as in chess with the exception that there is an additional piece which is called the "bodyguard". The starting position is similar to chess, except that a bodyguard each is placed between king and bishop and between queen and bishop with a pawn in front and there are two more rows in the middle. The game is not as popular as western chess or Shatar.
