A lesser-known weapon against the Dragon

Hmm, Bg7xh6 seems like a pretty viable move, and after Qh4xh6, then the pawn could go to f4 to continue a decently strong attack on your pieces, while making his light squared bishop stronger in that position. But I'm a newb at chess, so you can correct me :P

i play the dragon and im not sure about this, but isnt the dragon the best defence to the grand prix attack anyway?

Black's set up was fine, except he omitted to play e6 early enough to slow White's ambitions viz-a-viz playing f5. He certainly pays the price for his untimely expansion on the Queen-side, well played.

I play GPA with White as well...good results with low rating players and medium rating players in blitz chess...but is tough to win with it with a good player in a tournament...as GPA plan is pretty easy to grasp

Chessowns, please give me move #'s and a variation. Bxh6 for black could have happened on many moves, so it's hard for me to identify your idea. Generally, black does not want to give up his dark squared bishop in the Dragon because it is so vital in the defence of the dark squares around his King, thanks for your post!

Quite untimely indeed. When I saw him playing on that side of the board I thought to myself...bend him over hes got blinders on.

Chessowns, thanks for your post. On ...13. Bxh6 14.Qxh6 fxe4 15.Ng5 15... almost any legal move for Black, seriously, think of anything in this positiion, like 15...Nbd4(to try and back up the f6 knight which white will soon kill for a mating attack @ h7 via Rxf6.
After 16.Nxd4 in this position, Black has every right and reason to resign (if 16... Nxd4, 17. Qxh7#)
Now earlier, I highlighted 14...fxe4 , which looks like a totally legit, natural move for Black but ultimately loses because of the opening of the f-file. Instead of 14...fxe4, a well prepared Black player should play 14...e6! to try and keep the f-file closed momentarily.
The reason I like playing the GPA for white is because unprepared Black players can make natural moves like 14...fxe4 and white can contiune with a vicous (and often times fatal) attack.

Streetfighter,
I don't play open Sicilians from the White side very often. However, your move order seems favorable and I will eventually give it a try as I will need to learn to play open Sicilians eventually. Thanks for your input!
Also, what do you feel like White's plan should be after
1.e4 c5 2. Nc3 e6 3. f4 d5 ? in which Black goes for the d5 thrust right away.
