Every page is also served as markdown at its URL plus .md. A blockade is the plan of stopping an enemy pawn by occupying the square it must move to next, most often a passed or isolated pawn. A blockade is the plan of stopping an enemy pawn by occupying the square it must move to next, most often a passed or isolated pawn, with a piece that stays safe and useful there. A pawn that cannot step forward cannot become a queen. Blockading means putting one of your pieces on the square in front of the pawn and keeping it there, so the pawn is held by a body instead of by [tactics](https://georgelichess.com/glossary/tactic.md). Aron Nimzowitsch made the idea central to his teaching, and he stressed which pawns deserve it: [passed pawns](https://georgelichess.com/glossary/passed-pawn.md), which no enemy pawn can stop, and [isolated pawns](https://georgelichess.com/glossary/isolated-pawn.md), whose neighbors cannot support a push. [Knights](https://georgelichess.com/glossary/knight.md) make the best blockaders. From the blockade square a knight still attacks several important squares, while a bishop that stands in the path of a pawn sees much less, and a rook is happier on an [open file](https://georgelichess.com/glossary/open-file.md). A queen should not be tied to the job. A good blockade does two jobs at once. It freezes the pawn and it places your piece on a strong central square, where the pawn itself shields it from some attacks. The frozen pawn then becomes a target, and its owner may have to defend it with pieces. Before you commit, check that no enemy pawn can chase the blockader away, and that the piece has other work besides guarding the square. Otherwise a [pawn lever](https://georgelichess.com/glossary/pawn-lever.md) or a single exchange can set the pawn free. ## Example position Black's pawn on d5 is passed, because White has no pawns on the c, d or e files, and isolated, because Black has none on the c or e files. White's knight on d4 stands on the square in front of it and blocks its advance. Position (FEN): `3r2k1/pp4pp/3b4/3p4/3N4/8/PP3PPP/4R1K1 w - - 0 1` Compare it with [Isolated queen's pawn structure](https://georgelichess.com/glossary/isolated-queens-pawn-structure.md). A structure in which one side has a pawn on d4 (or d5) with no friendly pawns on the c- or e-files, giving active pieces and attacking chances but a long-term weakness in endgames. It sits close to [Overprotection](https://georgelichess.com/glossary/overprotection.md). Overprotection is the practice of guarding an important pawn, square or piece more times than the opponent's threats demand, so the point is rock solid and the guarding pieces can take useful posts around it. It sits close to [Stonewall structure](https://georgelichess.com/glossary/stonewall-structure.md). A pawn formation with pawns on c6, d5, e6 and f5 (for Black) or c3, d4, e3 and f4 (for White) that builds a solid wall controlling e5 or e4 but leaves the light-squared bishop passive.
