Alphabetic Chess: The squares are considered in the order a1, a2…a8, b1…b8, c1 and so on to h8. At each turn, only the unit standing on the square which comes earliest in this order may move. However check and mate are normal.
Nightrider(N): Operates along straight lines with squares lying a Knight’s move away from each other.
