10.Bd2 g6 and then either 11.0-0-0 Bg7 (11...0-0-0 runs into 12.h4) 12.h4 or 11.h4 Bg7 12.0-0-0.  Probably 10.h4 is more precise.

I am not quite ready to claim that White is better, but my investigations seem to show that at best, Black must play very precisely and even then may just manage to equalize.  OTB I would be much happier to be White.  That is with 12...0-0, which is a very risky move. 

12...h6 looks to be the sort of move that admits g7-g6 was a mistake, and I believe it's probably +=, but I haven't looked very deeply.  But Black's best play after an early f2-f4 and later h2-h4 is essentially never to play h7-h6, so White must gain if his early h2-h4 is answered with that move.  So it would seem to me, anyway.

Really, the short answer is "Yes."

If I'm right, we'll see a decline in Black's use of 11...Bb7, 12...g6.

Why don't I have that game?!  The Elos are high enough to make it into my db.  What, wasn't it in TWIC?

Anyway, yes, it shows the danger for Black.  I had earlier analyzed the position after 14.Qg4 and I believe that 14...d5 (as played) was a mistake.  Best, I believe, is the retrograde 14...Bc8, which looks terrible but is necessary because Black desperately needs to impede White's setting up a battery on the h-file (the positions with White's queen on h7 and Black's king of f8 are mostly lost for Black), and the c8 bishop will speak for some important kingside light squares.  One line I looked at was 15.hxg6 fxg6 16.Qh4 h5 17.Bd3 (Black also has to reckon with 17.g4) 17...Qd6! (this works because Bc2 loosens c4, Rh3 deprives the Q of h3, and any move of the d2 B is awkward) and, after either 18.Bc2 or 18.Rh3, 18...Qf6.  I am not sure that Black can hold after 14...Bc8, but I am fairly sure that more cosmetically attractive moves are worse.

As in this one?

an improvement may be 19...Qf6 20.Nf3 Kb7 21.Qb3+ Ka8 22.Nxe5 Rxe5 23.Bc3 Nxc3 24.Qxc3 Re6 25.Qxf6 Rxf6

That thread is not quite the same because, after 10.Bd2, it only looks at 10...0-0-0, not 10...g6, which is the new idea.  But the part about 10.h4 is relevant.

I would appreciate anyone's criticism of 10.f4 0-0-0 11.Be3 f6 12.c5 Nd5 13.Nxd5 cxd5 14.exf6 Qe4!?.

I think 11...c5 is better here

Kuzmin (Yearbook 98) gives 10.f4!? as an interesting try for an advantage:

10.f4!? 0-0-0 11.Be3! f6 12.c5 Nd5 13.Nd5 cd5 14.ef6 Qf6 15.0-0-0 d4 16.Bd4+=
