Blockading a passed pawn

Parking a piece squarely in front of an enemy passed pawn to stop it dead.

A passed pawn is dangerous only if it can advance, so the first response is to blockade it — plant a piece on the square directly in front so it can't move. The knight is the ideal blockader (it still controls squares around it), and the blockading piece is often immune because the pawn can't capture straight ahead.

Nimzowitsch's dictum 'the passed pawn is a criminal that must be kept under lock and key' captures it: blockade first, then round the pawn up at leisure. A well-blockaded passer is neutralised; an unblockaded one wins games.

Why it matters

Blockading is the standard, reliable way to defuse a passed pawn — knowing to blockade (and with which piece) turns a dangerous passer into a harmless one.

The mistake everyone makes

Trying to attack a passed pawn without first blockading it, so it simply advances or queens while you're busy.
