Thanks kylemeister, I forget to even check NCO these days. When i did it only mentions Ndf6, although there is a possible transposition to the position it reaches.
Still, I wonder why Schandorff would recommend allowing Nf6+ ef ?

In a recent tournament I was surprised by my opponent playing this variation. We continued 3...,de 4.Ne4 Nf6 5.Bc4 Nbd7 6.Nf6+. Checking in my copy of Schandorff's book I found that I had remembered the first few moves of the recommended antidote. However, after 4..., Nf6 White had the option of 5.Nf6+ ef which may be okay but does not thrill me. Are there any drawbacks to playing 4.Ne4 Nd7 intending 5.Bc4 Ngf6 6.d4 Nb6 and taking the d4 pawn as recommended by Schandorff ? If not and I've not been able to discover any, why play 4...., Nf6 allowing white the option of doubling Black's pawns ?
