Herald
Both rooks can only travel three squares.
Rooks stop controlling whole files, so open files are no longer worth fighting for. Endgames change completely because a rook can no longer cut the king off from a distance. Castling is off.
What changes
The board does not start the way standard chess does.
Standard chess: Classical chess. Checkmate the king.
