Key ideas for both sides

White

  • Play e3 and Be2 or Bd3, then castle short; the first engine line shows Be2.
  • Answer ...Bd6 with Bg3 to keep the tension, as in the third engine line.
  • Take on c5 at the right moment and play c4 to hit d5.
  • Use Nbd2 and a3 to restrain ...Bb4 and ...Nb4 ideas.

Black

  • 3...c5 and ...Nc6 hit d4; after ...cxd4 and exd4 the structure becomes symmetrical.
  • ...Bd6 offers a trade of the f4 bishop, White's most active minor piece.
  • ...Qb6 pressures b2 and d4 if White develops the light bishop too early.
  • Plan ...b6 and a later bishop move to b7 to give the locked c8 bishop a future.

Plans and pawn structure

Black's light bishop is passive, so the plan is ...c5, ...Nc6 and ...Bd6, with ...b6 and the bishop to b7 later. White's plan is Bd3, Nbd2, O-O and Ne5 or c4. If Black trades on d4 and White recaptures with the e-pawn, the open e-file and the e5 square become important. If the dark bishops come off, the game becomes calm and balanced.

How to play against it

As Black, play ...c5 and ...Bd6 early so White cannot build the full setup without pressure. As White, keep the bishop with Bg3 if you want more tension, or accept the trade and use the e5 square.
