Key ideas for both sides

White

  • Hit the bishop with Ng3, the top engine move, then gain space with h4 and h5 to cramp Black's kingside.
  • Try Nc5, eyeing b7 and the bishop on f5, which leads to sharp play after ...e5.
  • The calm Qf3 with c3, Bd3 and Ne2 is a quieter way to keep a small edge.

Black

  • Retreat ...Bg6 when the bishop is hit, keeping it on the h7-b1 diagonal.
  • Build a compact setup with ...e6, ...Nd7 and ...Ngf6, and only then decide where to castle.
  • Against Nc5 hit back with ...e5 and ...Qb6, using the open center to punish the knight's trip.
  • Use ...h6 when White pushes h4, so the bishop can drop back to h7 instead of being trapped.

Plans and pawn structure

Black's bishop on f5 is the main topic. White chases it with Ng3, Nf3, h4 and h5, gaining space on the kingside, and later trades it off with Bd3. White often castles long and keeps the h5 pawn as a spike. Black keeps every pawn protected with ...e6, ...Nd7 and ...Ngf6, plays ...Qc7 and ...O-O-O or short castling, and later breaks with ...c5 against the d4 pawn. The pawn structure is White's d4 against Black's c6 and e6.

Where the engine's main line heads: White pawn d4, no e-pawns for White, no d-pawn for Black. White has a pawn on d4 and no e-pawn; Black has no d-pawn. White has more central space; Black's pieces are free and the d4 pawn is a target.

Where it goes next

How to play against it

As White, play 5.Ng3 and use the time to gain space with h4. Do not chase pawns: the slow squeeze is your plan. As Black, never let the bishop get trapped. Have ...h6 ready against h5 and keep the bishop able to retreat to h7.
