Nc3 dxe4 4. d5 Ne5 5. f3 exf3 6. Nxf3 Nxf3+ (6... Bg4 $2 {would be a disaster as White can play} 7. Nxe5 $1 Bxd1 8. Bb5+ c6 9. dxc6 a6 10. c7+ axb5 11. cxd8=Q+ Rxd8 12. Nxd1 { and White has won a piece.}) 7. Qxf3 Nf6 8. Bf4 {and White has more than enough compensation. The pawn on d5 is a thorn in Black's position and White's position is much easier to play. One sample line may go} a6 {to avoid any Nb5 or Bb5 tricks.} ({e.g. If} 8... g6 9. Nb5 {is strong.}) (8... Bd7 {to try and play c6.} 9. O-O-O c6 (9... Bg4 10. Bb5+ Bd7 11. Rhe1 {and White's development lead is overwhelming. It is difficult to find a defence to Black.}) 10. dxc6 bxc6 11. Ba6 Qb6 12. Nb5 $1 {is pure chess engine great analysis!}) 9. h3 { to prevent Bg4 and enable queen side castling.} g6 {what else?} 10. O-O-O Bg7 11. g4 O-O 12. Qe3 b5 13. Bg2 Bb7 14. d6 Bxg2 15. dxe7 Qe8 16. exf8=Q+ Qxf8 17. Rh2 {and White is much better. Maybe in the Nimzowitsch Defence, accepting the BDG pawn on f3 is simply bad but how many players of the Black pieces would know that?} *
