How the rook moves
The rook moves any number of squares in a straight line, along a rank or a file, as long as nothing is in the way.
The rook's move, in plain words
The rook moves any number of squares in a straight line, along a rank or a file, as long as nothing is in the way. It is also involved in castling, the one move where the king and a rook move together.
What to remember
- Rooks are strongest on open files, with no pawns in front of them.
- A rook on the seventh rank, close to the enemy pawns, is very powerful.
- Two rooks on the same file or rank protect each other.
Common mistakes
- Moving a rook out too early before castling.
- Leaving a rook on a closed file, where pawns block it.
- Forgetting back rank mate: a rook can deliver it, and your own king can fall to it.
