Gnu (GN): a leaper combining Camel (1/3,3/1) and Knight.  

Kоko Chess (Contact Chess): a move is legal only if the arrival square is adjacent to any piece, this applies also to the capture of King.

Koko chess: I think the correct definition is that the arrival square is restricted (by being adjacent to another piece), not the departure square. Please note as per the definition given now, 1...GNb7 is a check and castling is not permissible.

Oh, Ram, of course in Koko chess the arrival square should be adjacent to another unit. It was just translation mistake by me. It's corrected. Thanks!
