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. After the exchange on d5, White keeps pawns on a2, b2, d4 and e3, while Black has a7, b7, c6 and d5: White's c-pawn has been traded for Black's e-pawn. White gets a half-open c-file and Black a half-open e-file. The natural knight posts are e5 for White and e4 for Black. White's best-known plan is the [minority attack](https://georgelichess.com/glossary/minority-attack.md): two queenside pawns advance against three. After Rb1 and b4-b5, White aims to trade on c6 or force ...c5, leaving a [backward pawn](https://georgelichess.com/glossary/backward-pawn.md) on c6 or an [isolated pawn](https://georgelichess.com/glossary/isolated-pawn.md) on d5 to attack. Pieces help with Qc2, a rook on b1 or c1, and the bishop on d3 aimed at the kingside. Another plan is Nge2, f3 and e4, using the extra central pawn to grab space. Black should not sit and wait. Typical [counterplay](https://georgelichess.com/glossary/counterplay.md) is a kingside push with ...Ne4, ...f5 and a rook on the f-file, or the [central break](https://georgelichess.com/glossary/central-break.md) ...e5 when it can be supported. Black can also meet b5 with ...cxb5, getting a safe queenside file and trading the [weak pawn](https://georgelichess.com/glossary/weak-pawn.md) for activity. Common errors include White pushing b5 before the pieces are in place, which lets Black close the queenside, and Black passively allowing the attack without any counterplay. A useful tip: count how fast each side can bring a rook and a knight into action before choosing a plan. ## Example position White has pawns on d4 and e3 against Black's c6 and d5. Look for the queenside minority attack with b4 and b5. Position (FEN): `r1bqr1k1/pp1nbppp/2p2n2/3p2B1/3P4/2NBPN2/PPQ2PPP/R3K2R w KQ -` A neighboring idea is [Queenside majority structure](https://georgelichess.com/glossary/queenside-majority-structure.md). 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. Also worth reading is [Slav structure](https://georgelichess.com/glossary/slav-structure.md). 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.
