Key ideas behind this line

  • The thematic Nb5 jump hits the soft c7/d6 squares and provokes concessions like ...a6 or an awkward ...Na6; if Black ever allows Nc7+ it forks the king and rook.
  • White's standard development is e3, Bd3 (or Be2) and Nf3, keeping the powerful Bf4-Nc3 duo intact and retaining the option to castle on either wing.
  • Against a ...g6 fianchetto, White launches a kingside pawn storm with h4-h5 to pry open lines toward the black king.
