Schuyler's book about a repertoire with 1...Nc6 looks interesting, but in one of the first lines I examined I'm not totally convinced by his analysis:

p. 21: After 1.d4 Nc6 2.Nf3 d6 3.c4 g6! 4.d5! Nb8 5.Nc3 Bg7 6.e4 Nf6 7.Be2 0-0 8.h3 Nbd7 9.Be3 Nc5! 10.Qc2 a5 11.0-0 Nfd7! (all his punctuations) he gives 12.Nd4 e5 13.Ndb5 f5 with good play.

In my opinion White has the better game after the typical 14.exf5 gxf5 15.f4!
