Fun fact: "Rook" is from the Arabic word for the chesspiece, which is derived from the Persian word for the chesspiece. Its ultimate origin is not clear, though it could be from the Indian word for the piece, "rut, " which comes from the Hindi word "rath," meaning chariot.
Well, to hold up with the traditions, shouldn't the Rook only be able to go straight and sideways...diagonal is a no-no.
And then that means Bishops should only be able to move diagonally (zig-zag)!!!
