In N-Relay Chess, pieces gain the power to move as a Knight when they are defended by a friendly Knight.
Knights cannot capture nor be captured themselves.

The file contains five variants:

• N-Relay Chess The variant invented by Mannis Charosh around 1972
• Transparent N-Relay Long-range piece attacks are not blocked by Knights
• Double-Edged N-Relay Knights relay to enemy pieces as well as to friendly pieces
• N-Relay Bump Pieces can bump Knights aside.
• N-Relay Switch The author's favorite N-Relay variant. Pieces can bump and Knights can switch.
