Attacking the base of the chain

Undermine a pawn chain at its root — the rear pawn that supports the whole structure.

A pawn chain is only as strong as its base — the rear pawn that props up all the others. Rather than batter the well-defended head of the chain, you strike at its base with a pawn lever (e.g. …c5 against a d4-e5 chain, or …f6 against e5) so that when the base falls, the whole chain crumbles.

Nimzowitsch's rule 'play against the base of the pawn chain' is the guiding idea in blocked structures like the French and King's Indian. Identifying the base — and the lever that hits it — turns a static position into a concrete plan.

Why it matters

Blocked pawn-chain middlegames are won by hitting the base, not the head — knowing which pawn to attack (and with which lever) is the plan in whole opening families.

The mistake everyone makes

Piling pieces against the strong head of the chain instead of preparing the pawn break that undermines its base.
