The Rook is an important piece to use in chess and not very hard to learn. There is an easy rhyme I made up for the rook; here how it goes:
“Up, Down, Side to Side, that’s the way the rook will slide.”
The rook moves forwards, backwards, and sideways as many squares as it wants. It attacks the same way it moves and cannot skip over pieces. Like all the other pieces, it can only attack one piece at a time.
Each team gets two rooks and they start on the corners on the board. For white this is a1 and h1. For black this is a8 and h8.
