Now we'll look at the mainline in the Alekhine Variation. It occours after:
1.d4 f5 2.g3 Nf6 3.Bg2 e6 4.Nf3 Be7 5.0-0 0-0 6.c4 d6 7.Nc3 Ne4
White has some alternatives here:
A) 8.Qc2 Nxc3 9.bxc3
B) 8.Qc2 Nxc3 9.Qxc3
C) 8.Nxe4 fxe4 9.Nd2
D) 8.Nxe4 fxe4 9.Ne1
E) other less frequent played moves: 8.Nd2, 8.Bd2, 8.Bf4, 8.Qb3
F) White plays 7.Nbd2!?
A) 8.Qc2 White takes control over e4 and attcks the knight Nxc3 9.bxc3 White opens the b-file for his rook and the diagonal for the c1-bishop which could come to a3 sometimes. Black often gets counterplay against the weak c4-pawn.
9.bxc3!? Nc6!! 10.d5
a) 10.e4 e5! 11.Ba3 f4!?

Conclusion: White cannot gain any advantage here .
B) 8.Qc2 Nxc3 9.Qxc3 In my opinion this is better than 9.bxc3

Conclusion: A sound line.
C) 8.Sxe4 8...fxe4 9.Sd2!? This move shall black lure to play 9...e3, which would only be good, if white played 10.Nb3; but after 10.Nb1 white comes on to top. So black should play here, as if white had played 10.Ne1.
