I am the rook from chess. Who am I? A tower? A castle? Why am I called a rook? I don’t know, but according to people, I’m supposed to represent a Persian chariot. None of these things I mentioned are alive except for “people” and “rook”. If I represent a chariot, why am I talking right now? Anyways, I move horizontally and vertically any number of squares. I attend castling move.
