Hiashatar. Mongolian Decimal Chess.[All Comments] [Add Comment or Rating]

In my Hiashatar Zillions program I have implemented both variants: (1) the Bodyguard stymies only enemy pieces. It slides two squares and can capture also on the second square. (2) the Bodyguard stymies also friendly pieces.  It slides two squares, but it *cannot* capture on the second square.

The Bodyguard cannot give mate. The knight can always give mate. There is no castling. The Bodyguards are very effective in protecting the king so castling is unnecessary. (The king cannot be threatened from afar on an open line, if it's positioned beside a Bodyguard.)

The Bodyguard cannot affect a knight because the knight only makes one 'step', namely a jump. The Bodyguard always allows one step, also with sliders. If the knight was to be restricted in its movement, it couldn't move at all, which isn't logical, as the sliders are allowed to move.
