Key ideas for both sides

White

  • Castle and then push d4 to trade the e-pawn for Black's d-pawn, leaving a healthy kingside majority.
  • After ...dxc6, Nxe5 does not win a pawn because ...Qd4 hits the knight and e4.
  • Against ...bxc6, Nc3 and d4 open the center quickly to target the loose queenside pawns.

Black

  • Recapture with ...dxc6 to open the d-file and free the c8 bishop.
  • ...bxc6 keeps central pawns and leads to the Lutikov lines with ...Qf6.
  • Never play ...Nf6 here: the bishop retreats with Ba4 and White is simply a piece up.

Plans and pawn structure

White gives up the bishop pair to gain a structural plus: after d4 and the exchange of central pawns, White has four pawns against three on the kingside, while Black's doubled c-pawns cannot make a passed pawn. White aims for an endgame. Black uses the two bishops, the open d-file and quick development with ...Bg4, ...Qd6 or ...Qf6 to keep the middlegame lively and avoid simple trades.
