It would be good to explain why the white knight goes to c1 through b3 and not d3.
(5. Nd3? Rd2 6. Nc1 Rd6!! -+ {crucial, surprisingly deep and difficult to notice move that pins the white pawn f6 and forces the white king to leave the good g6 square, 6… Rd1 is waste of time}). After 5. Nb3!! Rb2?? with 6. Nc1 Rb6 is impossible.
