The Evolution of Modern Chess Rules

Chess was not always played the way we are familiar with it, i think it is. The first black and white board was put forward in year ten 90. A castling is a move where the rook and the king can change places. Other moves that have changed is the 50 move draw. If you're just stuck, would like four pieces on the board,. ah, if you can't get check made in 50 moves,  a if you're repeating certain moves, and that ends up in a draw.
