Now the paradox begins. The minority advances: b4, the smaller force marching at the larger. Black slows it the standard way. White supports and keeps coming. Black regroups toward the kingside — the other half of the trade, since each side attacks where their file points. The lever lands on b5, touching both a6 and c6. Whichever way the trades resolve, some Black queenside pawn ends up weak on an open or half-open file — that guarantee, not any won pawn, is what two White pawns spent themselves to buy."]]
The minority attack is strategy's best-named paradox: advancing fewer pawns against more — classically White's a- and b-pawns against Black's a-, b-, and c-pawns in the Carlsbad structure above — not to win the pawns but to wound them. The marching minority trades itself off at the moment of contact, and simple arithmetic does the rest: after the exchanges, the majority side has more pawns left on that wing, and at least one of them sits weak on a file the attacker's rooks already own.
