A knight fighting to intercept a distant passed pawn.
Why it matters
A knight can stop a passed pawn, but it needs the right route and it cannot do it from a distance the way a bishop or rook can. Working out whether it arrives in time is a counting exercise, and the counting is not obvious.
The knight's weakness is the rook's pawn. On the edge of the board the knight has half the squares it usually has, and a pawn on a7 or h7 can be genuinely impossible to stop.
See it on a board
The knight has exactly enough time. It steps to b3 and c1, which covers a2, and the pawn walks into the square the knight is already watching.
Checked: this line reaches a drawn position.
How to play it
- Find the square in front of the pawn that the knight can reach, and count the moves.
- Prefer routes that give check or attack the pawn on the way, so the pawn cannot simply run.
- Aim to reach the square directly in front of the pawn, or the one two ahead of it, from where the knight covers the promotion square.
At each level
The same idea, said the way it is taught at each age.
Bishop · ages 5–7
A knight can catch a passed pawn if it gets to a square in front of it. Count the moves before you decide it is too far.
Rook · ages 6–9
Rook's pawns are the exception. On the a- or h-file the knight loses half its squares, and pawns that look easy to catch are often not.
What goes wrong
- Chasing the pawn from behind, which a knight can never do fast enough.
- Blockading on a square where the enemy king simply drives the knight away.
Questions people ask
- Can a knight stop a pawn on the seventh rank?
- Sometimes, if it can reach the promotion square or the square in front. Against a rook's pawn on the seventh with the king nearby, usually not.
