Key ideas for both sides

White

  • Push d4 to trade the e-pawn for Black's d-pawn and reach a favorable structure.
  • Answer ...Bg4 with h3, and if ...h5 comes, do not take the bishop with hxg4.
  • After ...Qf6, Bg5 hits the queen and helps the center, as in the third engine line.

Black

  • Pin with ...Bg4 and meet h3 with ...h5, offering the bishop to open the h-file.
  • ...Bd6 and ...f6 protect e5 solidly, leading to the King's Bishop setup.
  • ...Qf6 defends e5 and prepares ...Bg4 or long castling with active rooks.

Plans and pawn structure

White wants d4 to trade the e-pawn for Black's d-pawn, leaving a kingside majority for the endgame. Black uses the bishop pair and active pieces: ...Bg4 pins the f3 knight, ...h5 offers sharp play on the h-file, and ...Qf6 or ...Bd6 keep e5 protected. If Black castles long, the game can turn sharp, with White pushing queenside pawns and Black aiming at the white king.
