Intro
1. d41… Nf62. c42… e63. Nc33… Bb44. e34… O-O
What you're training
Pin White's c3-knight with ...Bb4, control the e4 square, and be ready to trade the bishop for the knight to leave White with doubled, vulnerable c-pawns in return for the bishop pair.
Strengths
- ...Bb4 pins the c3-knight, the main piece defending the e4 square — so White can't easily push e4 and build the broad centre.
- The signature trade is ...Bxc3: Black surrenders the dark-squared bishop to inflict doubled c-pawns on White, a long-term structural target.
- Black plays a piece-and-pawn game against the centre — ...d5, ...c5 and ...b6 with ...Bb7 all fight for e4 rather than occupying the centre directly.
- It's a balanced, strategic defence: sound, flexible, and rich in the classic struggle of bishop pair versus pawn structure.
Watch out for
- Don't trade ...Bxc3 automatically — only do it when the doubled pawns are a real, lasting weakness, or you just hand White the bishop pair for nothing.
- Letting White play e4 unhindered surrenders the whole point of the pin; keep the pressure on that square.
- If you damage White's pawns but then let the centre open for the bishop pair, the two bishops can outweigh the structural defect — keep the position controlled.
