The rook is a powerful piece that moves in straight lines—along ranks (rows) and files (columns). Each side starts with two rooks in the corners. Let's learn how they work!

Rooks are most powerful on open files (no pawns blocking) and the 7th rank (where they attack enemy pawns). In the opening, rooks start trapped behind pawns—that's why castling (covered later) helps activate them.
