Fewer pawns, but they go first
In a minority attack the pawns advance on the wing where you have fewer than your opponent. The goal is not to break through but to trade pawns, so that your opponent is left with a pawn that no other pawn can protect. The pieces can then go after it.
The position often comes from the Exchange Variation of the Queen's Gambit. The pawn structure is often called the Carlsbad structure, and it is described on the page about pawn structures.
The plan step by step
- The rook first. A rook on the b-file or the c-file helps the pawns forward and is ready when the file opens.
- The b-pawn advances, to b4 and b5, often with the a-pawn in support.
- Trade on c6. If Black recaptures with the b-pawn, the pawn on c6 becomes weak on a half-open file. If Black takes on b5 with the c-pawn, the pawn on d5 becomes isolated.
- Attack the weakness with the pieces: the rooks on the c-file, a knight against c6 or d5.
Petrosian's minority attack
Tigran Petrosian played it at the USSR Championship in Tbilisi in 1959. The game had begun with a different opening, but the structure on the queenside was the same: two white pawns against three black ones.
- 12.…
- 13.
- 14.…
The minority attack rarely wins anything right away, and the position was balanced when the b-pawn advanced. But the weakness came. Eight moves after 14.b5 Black's queenside pawns were broken up, and Petrosian won the game.
Black's counterplay
The minority attack takes time, and meanwhile Black looks for counterplay on the other side of the board, often against White's king. Another way is to meet the pawns on the queenside with …a5 and try to make White's b-pawn the weak one instead.
Common mistakes
- Pawns without pieces. If the b-pawn advances without the rook behind it, it can become the weak pawn itself.
- Forgetting the king. While White plays on the queenside, Black can attack on the kingside.
- The wrong capture for Black. Taking on b5 with the c-pawn without thinking leaves an isolated pawn on d5.
Remember
- The minority advances to trade, not to break through.
- The goal is a weakness, a pawn on c6 or d5 that no other pawn can protect.
- The plan is slow. Keep an eye on the kingside meanwhile.
Frequently asked questions
What is a minority attack?
A plan where the pawns on the wing where you have fewer pawns advance, to trade and leave your opponent with a weak pawn. Usually it is White's a- and b-pawns against Black's a-, b- and c-pawns.
In which openings is the minority attack played?
Often in the Exchange Variation of the Queen's Gambit, where White gets two pawns against three on the queenside. The same pawn structure, with the colors reversed, can arise in the Exchange Variation of the Caro-Kann. Then it is Black who has the minority.
How do you defend against the minority attack?
With counterplay on the other side of the board, often against the king, while White is busy on the queenside. Another way is to meet the pawns with …a5 and try to make White's b-pawn the weak one instead.
