Key ideas for both sides

White

  • Push 3.d5, the engine's first choice, to kick the knight back to b8 and gain a full tempo.
  • Follow with Be3, Qd2 and Nc3, as in the main engine line, and consider castling long with a kingside pawn storm.
  • Against ...e5 in the Nf3 lines, use Bb5 to pin the c6 knight and add pressure on the center.
  • After ...exd4, recapture with the knight on d4 and keep a comfortable space edge in the center.

Black

  • After 3.d5, retreat with ...Nb8 and set up with ...g6, ...Bg7 and ...c6 to hit the d5 pawn.
  • If White develops with Nf3 and Nc3, play ...Nf6 and ...e5 for a solid open game.
  • Use ...Bd7, as in the engine lines, to break the pin when White plays Bb5.
  • Do not let the c6 knight get stuck; if d5 comes, reroute it quickly to b8 and later d7.

Plans and pawn structure

Black's ...d6 keeps the e-pawn flexible. After 3.d5 the knight retreats to b8, and Black often builds a Pirc-style setup with ...g6, ...Bg7 and ...c6, while White uses Be3, Qd2 and Nc3 for space and a possible kingside attack. If White develops with Nf3 and Nc3 instead, Black plays ...Nf6 and ...e5, and after ...exd4 Nxd4 the game resembles a Philidor with active White pieces and Black's bishop on d7.

How to play against it

White, 3.d5 is the most testing reply because Black's knight loses time. Then develop with Be3 and Qd2. Black, after 3.d5, play ...Nb8 and ...g6 and look for ...c6 or ...e6 to hit the d5 pawn before White completes development.
