The book arrived at my house this morning

Indeed I was immediately reminded of Fischer-Robatsch (which was one of Fischer's 60 Memorable Games), but the two cases don't seem very comparable.  For instance, it would seem that in the BDG case it might be quite a decent idea for Black to play ...Bg4 at some point, which in the Fischer case would have just run into f3.

Still I wonder how to compare this with 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd8 4.d4 Nf6 5.Nf3 g6 6.Bf4 Bg7 7.Qd2.

This reminds me of the old discussions on the Englund Gambit where Black "prepares" the ...e5-thrust with ...a6 and/or ...h6, e.g. 1.e4 h6 2.d4 e5.   I also note that White actually lost the game given!

For now I'll stick to meeting 5...g6 with 6.Bf4 and 7.Qd2 (unless this new book casts doubt on the idea, but I doubt that it will- the queenside castling, h-pawn hack idea is a common motif against a kingside fianchetto, think of the Yugoslav Attack for instance).  That is, if I ever meet 5...g6!

Yes, my apologies- it wasn't obvious from the chapter & variation list, but it is certainly covered (as is the 5...Bf5 6.Bd3 suggestion earlier).  Looks like a very comprehensive coverage then, even though the foreword implies otherwise!

Looking at Amazon's preview, which shows the main variations covered, I'm intrigued to see that 5...c6 (and by implication 4...c6 5.Bc4) focuses on the traditional 7.0-0 approach rather than the newer ideas following 7.Bg5.  I've long had the impression that 7.0-0 e6 8.Ne5 Bg6! is better for Black while 8.Ng5 Bg6! doesn't quite work for White either.

Another lesser one is 5...Bf5 met by 6.Ne5, I remember that in the latest Chesspub analysis this move appeared to give White some chances but that 6.Bd3 looked more promising.

Another reason to get the book and see what turns up, as I'm left wondering what Scheerer has found for White in those lines!

That might be interesting. I should point out however, that 8 h3 Nc6 is hardly critical according to a recent game I played. The event was the Gambit Tournament in Ridgewood, New Jersey. We had to play two games with each opponent in a 4-player quad. In the first round, all players had to start with the King's Gambit Accepted, 1 e4 e5 2 f4 ef4; in the second, BDG Accepted; in the third, Smith Morra Gambit Accepted. I scored 4.5/6 and took first place.

BDG: Bogoljubow Defense

1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 ef3 5 Nxf3 g6 6 Bc4 Bg7 7 00 00 8 h3 Nc6 9 a3!?

This is a new move. Much better than the speculative and tricky 9 Qe1 Nxd4 10 Qh4 Nf5.

9...Na5 10 Ba2 b6 11 b4 Nb7 12 Bg5 Nd6 13 Rfe1 Bf5 14 Ne5 e6 15 Qf3 Qe7 16 Nc6 Qd7 17 Ne5 Qe7 18 Nc6 Qd7 19 Rad1 Nh7 20 Be3 Ne8? 21 Ne7+ Qxe7 22 Qxa8 Qd6 23 Qxa7 eventually 0:1 much later.

So, after 8 h3 Nc6 9 a3!? seems to be a good move!

Yes, correct. But some people still play ...Bxc2. Not that this move is any good, though.
