Thinking questions in this lesson
You can ask yourself these thinking questions in any position. They help you find a good move.
- Which piece could be better placed?
Step 1 of 6
Look first
The black pawns are still on their starting squares. That is the seventh rank, directly in front of Black’s back rank.
Tap the square where your rook can reach the seventh rank.
Arrow keys move the focus across the squares. Enter or Space marks a square or removes the mark.
Choose a square from a list
Position as a list
White
- King g1
- Rook d1
- Pawn a2
- Pawn b2
- Pawn f2
- Pawn g2
- Pawn h3
Black
- King h8
- Rook a8
- Pawn a7
- Pawn b7
- Pawn f7
- Pawn g7
- Pawn h7
Step 2 of 6
Decide
Which piece could be better placed? Here it is your rook on the open d-file.
Which plan makes the best use of your rook?
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.
Position as a list
White
- King g1
- Rook d1
- Pawn a2
- Pawn b2
- Pawn f2
- Pawn g2
- Pawn h3
Black
- King h8
- Rook a8
- Pawn a7
- Pawn b7
- Pawn f7
- Pawn g7
- Pawn h7
Step 3 of 6
Try it
Your rook is on d7. Black has protected f7 with the king. Which pawn do you capture now?
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.
Choose a move from a list
Position as a list
White
- King g1
- Rook d7
- Pawn a2
- Pawn b2
- Pawn f2
- Pawn g2
- Pawn h3
Black
- King g8
- Rook a8
- Pawn a7
- Pawn b7
- Pawn f7
- Pawn g7
- Pawn h7
Step 4 of 6
Why does it work?
Several pawns often still stand side by side on the seventh rank. Pawns on the same rank cannot protect each other.
Your rook attacks them from the side. Choose a target: a pawn your opponent cannot protect well.
Key idea
Bring your rook to the seventh rank if there is a target there.
When does this apply?
A target could be a pawn your opponent cannot protect well. First check that your rook will be safe there and that your own back rank will remain safe.
Step 5 of 6
New position, same idea
The board is turned round: rank 8 is now at the bottom.
You are playing Black. Bring your rook to your seventh rank.
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.
Choose a move from a list

- Pawn a7

Nimzowitsch and today
Source
Nimzowitsch calls the invasion of the seventh and eighth ranks the logical consequence of play on an open file. He sees it mainly as an endgame advantage. He advises choosing an attacking target from the start, a pawn or a square, instead of moving back and forth without a goal. Learners should try to break in early, even if it goes wrong at first. The text and positions are newly written for the course.

Today’s view (editorial note)
A rook on the seventh rank is still considered a typical endgame advantage today. It is strong when it attacks pawns or keeps the king on the back rank. But first check that it is safe there. If there is no target, another move is often better, for example a king move.
