Key ideas for both sides

White

  • Play 3.d4, then h3 to force ...Bxf3, getting the bishop pair as in the top line.
  • After Qxf3, develop with Be3 and Nc3, with a strong center and quick queenside castling ideas.
  • Against ...e5, keep the d4 and e4 tension and use the bishop pair once the center opens.

Black

  • Play ...Nd7 and ...e5 to build a solid center after the pin.
  • Trade on f3 when White plays h3, then develop with ...g6 and ...Bg7.
  • Use ...c5 and ...Nd7 to fight for d4 in the 3.h3 line.

Plans and pawn structure

White aims for d4 and h3 to win the bishop pair and keep a strong center. Black trades on f3 and plays ...e5, ...g6 and ...Bg7 for a solid setup. The tension between d4 and e5 decides the game. If White takes on e5 or Black takes on d4, lines open and the bishop pair grows stronger. If the center locks with d5, Black's knights find good squares like c5 and the game gets slower.

Where the engine's main line heads: Central tension: d4 and e4 against e5. Central tension: d4 and e4 against e5. One capture changes the character of the game.

How to play against it

As White, play 3.d4 and h3 to win the bishop pair. Don't let Black get ...e5 without pressure. Develop with Be3 and Nc3 and keep the center tense. Do not rush d5, which closes the position and makes the bishop pair less useful.
