The idea
Black pins the knight on c3 and fights for e4 with pieces, giving the game a Nimzo-Indian character inside a Queen's Gambit structure.
Main line: 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Bb4 5.Bg5 h6 6.Bxf6 Qxf6 7.e3 O-O
What White wants
- Develop e3 and complete castling before opening the centre
- Choose Bxf6 according to its tactical and structural consequences
- Prepare e4 while watching the pin on the c3 knight
What Black wants
- Use ...Bb4 to pin c3 and increase central pressure
- Consider ...Bxc3 only when the damaged pawns justify the bishop trade
- Challenge the centre with ...c5 and active piece play
Key idea
Understand this and the moves stop needing to be memorised.
The pin contests White's central expansion
The b4 bishop pins the c3 knight to the king, making e4 harder to support. Bxf6 Qxf6 exchanges White's bishop for a knight and leaves Black with the bishop pair. If Black later plays ...Bxc3, both sides instead have one bishop and one knight.
Common mistake
Exchanging minor pieces without counting what remains. In the example, Bxf6 and ...Bxc3 remove one bishop and one knight from each side; White has doubled c-pawns, but neither side retains a bishop pair. Judge activity and structure, not a nonexistent two-bishop advantage.
Mistake example: O-O.
