Key ideas for both sides
White
- Play 5.Bxc4, the top engine choice, then castle and decide how to meet ...c5.
- The slower 5.h3 keeps the pawn on c4 for now and waits for Black to commit with ...b5.
- Prepare Qe2 and Rd1 so the d-file is ready when the c-pawn trades on d4.
- Use Nc3 and e4 later to build a center once Black's queenside is set.
Black
- Answer Bxc4 with ...a6 and ...c5, matching the main engine line and freeing the queenside.
- After b3 ideas, trade on d4 and swap queens for a quiet, equal game.
- Develop the f8 bishop to e7 and castle before opening the center.
- Against 5.h3, ...b5 grabs queenside space and keeps the c4 pawn for a while.
Plans and pawn structure
Black's ...e6 opens the f8 bishop and closes in the c8 bishop, which usually comes out via b7 after ...a6 and ...b5. White recaptures on c4, castles and keeps the center flexible. The main clash comes when Black plays ...c5: White may take on c5, allow an isolated d4 pawn, or play b3 as in 7.b3 cxd4 8.Qxd4 Qxd4. Piece activity and the d-file decide most games from here.
