Rook

The piece that moves any number of squares along a rank or file — worth about five pawns, and at its best on open lines.

The rook is worth roughly five pawns (a 'major piece', like the queen), but unlike the queen it starts the game boxed in behind its own pawns and pieces — a rook's opening job is usually just getting out. An open or half-open file turns a rook from a spectator into one of the most powerful pieces on the board, because nothing blocks its path down the file.

Rooks belong behind passed pawns (their own to push them, the opponent's to blockade them) and on the seventh (or second) rank, where they can attack pawns and pin the enemy king to the back rank at the same time. Two connected rooks doubled on a file or rank are devastating — the classic 'rooks on the seventh' finish entire games by themselves.

Why it matters

Because a rook needs open lines to do anything, 'activate your rooks' is one of the most repeated pieces of advice in chess — a rook still sitting on its starting square in the middlegame is a piece not participating in the game at all.

The mistake everyone makes

Leaving rooks passive behind a wall of your own pawns for the whole game, rather than opening a file (even at the cost of a pawn) to get them into play.
