Key ideas for both sides

White

  • Take with 3.cxd5, the top engine move, and after 3...Bxb1 4.Rxb1 Qxd5 develop with e3 and Nf3.
  • The 3.Qb3 Queen Attack hits b7 and d5; after ...dxc4 Qxb7 Black's queenside gets loose.
  • Develop with Nc3 and Qb3 to pressure b7 and d5 together before Black finishes.
  • Use the bishop pair after Black trades on b1, opening lines with e4 later.

Black

  • Answer cxd5 with ...Bxb1 and ...Qxd5, getting the queen active quickly in the center.
  • Against Qb3, play ...dxc4 and ...Nd7 to defend and counterattack the queen.
  • Use ...e6 and ...Nf6 for a solid setup once the bishop is out.
  • Keep b7 covered with ...Nc6 or ...Qc8 when the queen comes to b3.

Plans and pawn structure

Black develops the bishop early, so b7 is weak. White's main plans are cxd5 with the bishop pair, or Qb3 to hit b7 and d5. After 3.cxd5 Bxb1 4.Rxb1 Qxd5, White has the two bishops and Black has quick development but no light-squared bishop. In the Qb3 lines, Black can grab c4 and use the open b-file. Black's long-term setup is ...e6, ...Nf6 and ...c6.

How to play against it

As White, play 3.cxd5 or 3.Qb3 to exploit b7. As Black, know these lines in advance and develop quickly. Avoid leaving b7 weak for long; ...e6 and ...Nc6 should follow soon. The bishop on f5 is an asset only if b7 holds.
