I don't see anything unorthodox in gambiting a pawn for a lead in development, some open lines and central domination. You would not call the Danish, the Evans and the KG unorthodox either, would you? They have an equally rich history in WCh matches. 

Neither the BDG nor 1.e4 d6 2.d4 Nf6 3.f3 is unorthodox. And the exchange manoeuvre Bh6 is as old as the Pirc itself.

The secret to success in chess is to choose your opponents carefully.

Actually, the move order should be 1 d4 Nf6 2 f3 d6 3 e4 g6 4 Be3 Bg7 5 Qd2 00 6 Bh6. In other words, 
getting an early e2-e4 first by White.

I was analysing without sight of board, so a typo crept in. As for the line 1 d4 Nf6 2 f3 c5, I usually play
3 d5 here. Of late I discovered a few real interesting moves here, but will keep my analyses secret. Suffice to say I beat some strong players on Internet Chess Club with this novelty.

As for 1 d4 Nf6 2 f3 d5 3  e4 e6 4 f4 c5 5 c3! Note that this move allows a nice pawn chain. 5...Nc6 6 Nf3
Qb6 7 Qb3 =

Point is, this whole line is a transposition into the French Defence. I have played it quite a few times as White, with good results.

Now, you ask about 3...Nbd7, 4...e5. I assume you talk about the line 1 d4 Nf6 2 f3 d6 3 e4 Nbd7 4 Be3 e5 5 d5

Pretty even. I have played against this line many times. Once I find some of my old games, I will post them here.

Lane includes the Hubsch is his BDG book.  I mean no offense but you seem upset over a fact.  The fact is that the Hubsch disallows you pet lines.  Isn't that the point of opening preparation...to get positions you know and like and your opponent knows less and likes less?  There are pros and cons to any opening move.  Why shouldn't the black Indian player take advantage of the fact that the Hubsch is favorable for him?  He'd be foolish not to IMHO.  Goodness knows there are enough unfavorable facts for the Indian player to contend with later on.    BTW, aren't you avoiding others' pet lines by playing the BDG in the 1st place?  Again, sincerely, I mean no offense.

Any decent Pirc-player knows and that is something I know from my own experience. One of the opening lines I really know something about is the Argentinean Attack 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f3 followed by 5.Be3 and 6.Qd2. I have played and studied it for more than 25 years. A few short remarks about it.
1) this move order is imprecise because Black will not castle if he has looked into a book on the Pirc for more than 5 seconds. (S)he will play b7-b5 and Qd8-a5 instead. The black king is safer in the centre.
2) so these days White choses another move order (4.Be3) and only plays f2-f3 after Black has castled. I have scored more than 80% with this.
3) after 4.f3 Black does not even need to play ...Bg7; again ...b5 is superior.

Conclusion: 1.d4 Nf6 2.f3 g6 3.Be3 (are you sure you don't mean 3.e4 first?) d6 4.Qd2 Black plays c6. Oh! 5.Bh6 is a loss of tempo! What to do! Trust me, even LDZ does not know. At least he does not tell us; as usual founding his conclusions on at least one inferior move by Black (0-0?!).
Even worse - maybe ...0-0 is not inferior at all. I refer to Vigus' work on it for more details.

And that's the first justification of 1.d4 Nf6 2.f3 g6!? - if White plays Nc3 Black gets a good version of the Pirc. So White should enter the Sämisch. I imagine that quite a few KID-players will be very happy with that.

Another suggestion: 1.d4 Nf6 2.f3 d6 3...Nbd7 and 4...e5. Oh! The idea Be3, Qd2, Bh6 loses a piece! What to do! LDZ is on a loss!
Anyhow, this is (or 2...c5) is what a player as Black should do if (s)he wants to enter the Hübsch.

After 1 d4 Nf6 2 f3 g6 3 Be3 Bg7 4 Qd2 00 we have a Pirc Defense. Personally, I prefer to exchange the pesky Bg7 via Bh6! as soon as possible. This prevents any cheapo tricks on the long a1-h8 diagonal and confuses the vast majority of my opponents. Oh, the Bg7 is gone! Now what to do? Trust me, not everyone knows!

With regard to 1 d4 Nf6 2 f3 c5, the move 3 d5 is perfectly playable. I have played against both 2...c5 and 2...g6, so I know what to do here.

Now, Matrixx's suggestion about the French looks good. However, I have played against this line many times myself. This isn't anything that is not covered in books about the French Defense or opening databases. A good knowledge of that should be enough to give White the edge.

I am talking about 1 d4 Nf6 2 f3 d5 3 e4 c5 4 e5 Nfd7 5 c3 Nc6, of course. In fact, this line is good for White, since the c3-pawn supplements the White defense of d4. In other lines, such as 1 d4 Nf6 2 Nc3 d5 3 e4 e6, that is not possible, because the Nc3 blocks the c2-pawn.

[Rude remark removed by Markovich]

Finally, my lines are well-named, because it was I who invented or popularized them. If you have a problem with that, then don't you invent a few gambits or lines yourself? Then you can name it all you want, however you want.

Oh, wait... I think I have some games against Yelena Dembo on the ICC... with the BDG!

Will post these next time.
