Minority attack
A minority attack is a plan in which two or three pawns advance against a bigger enemy pawn group on the same wing, aiming to leave a lasting weakness behind rather than to make a passed pawn.
The usual instinct says that the side with more pawns on a wing should be happy. A minority attack turns that instinct around. You take the smaller group and push it forward on purpose, not to promote a pawn but to trade pawns off until what remains on that wing is a target.
The textbook setting is the Carlsbad structure, which comes from the Exchange Variation of the Queen's Gambit Declined. White has pawns on a2 and b2, Black has a7, b7 and c6, and White's pieces stand ready behind the advance: a rook on b1, a knight on c3, the queen near the queenside. White plays b4, often a4, and then b5. If White captures on c6 and Black recaptures with the b-pawn, the c6 pawn becomes a backward target on a half-open file and the a-pawn is left isolated. If Black captures on b5 first, the queenside opens and White's pieces gain squares and files there.
There is a price. The attack takes several tempi, it removes your own queenside pawns from the board, and an opponent who strikes in the center or on the kingside while you are busy can make you regret it. Be sure your pieces are well placed before the first push.
The lesson reaches beyond this one structure: judge a wing by what it does to the pawn structure, not by the pawn count. Ask which pawn will be left weak after the exchanges and whether you can win it.
Compare it with Queenside majority structure. A pawn structure where one side has more pawns on the queenside than the opponent, such as three against two, and can create a passed pawn there while the other side holds a kingside majority.
It sits close to Slav structure. The solid Black setup with pawns on c6 and d5 that supports the center while keeping the c8 bishop free to develop outside the pawn chain, usually on f5 or g4.
Where "Minority attack" fits your own play is easier to judge with a coach reading your games; the first lesson is a paid one-on-one review that ends in a written plan.

A pawn majority is a larger number of pawns on one wing or in one area of the board than the opponent has there, giving the chance to create a passed pawn.
A weak pawn is a pawn that is hard to defend with other pawns and so must be protected by pieces, making it a long-term target for the opponent.
A backward pawn is a pawn that has fallen behind the pawns on neighboring files and cannot safely advance, because the square in front of it is controlled by an enemy pawn.
The pawn setup from the Queen's Gambit Declined Exchange Variation, with White pawns on d4 and e3 against Black pawns on c6 and d5, where White often launches a queenside minority attack with b4 and b5.
A half-open file is a file on which one side has no pawn while the opponent still does, giving the side without a pawn a line along which to attack the enemy pawn.
An isolated pawn is a pawn with no friendly pawn on either neighboring file, so no other pawn can ever defend it and the square in front of it is a lasting weakness.
