Sicilian Accelerated Dragon
1.e4 c5 2.Nc3 g6 3.Nf3 Bg7 4.h4!?
This has been tried by grandmasters.
4...Nf6 5.d4!?
Playing on the flank and opening the centre is somewhat unusual, but the analysis engines Stockfish10 and Komodo10 are not unduly bothered.
5...cxd4 6.Nxd4 Nc6
More circumspect is 6...d6, which has been played by grandmaster Yunguo Wan.
7.Nxc6 bxc6 8.e5 Nd5!?
The engines prefer 8...Ng8 to this pawn-sac.
9.Nxd5 cxd5 10.Qxd5 Rb8 11.Bd2?!
The engines suggest 11.Qc5 0-0 12.h5, with a slight edge for White according to Stockfish10, but Komodo10 reckons Black has full compensation for the pawn.

11...Qc7?
I rejected 11...Rxb2 because of 12.Ba5, missing 12...Bb7, when Black is better.
12.Bc3 Bb7 13.Qd4 0-0 14.h5 Qc6?!
The engines give 14...d6 15.hxg6 hxg6 16.Qxa7 dxe5, but with advantage - a winning one, according to Stockfish10 - for White.
15.hxg6 fxg6 16.Bc4+ e6 17.f3 Rf5 18.f4?
18.0-0-0 is strong as 18...Bxe5? 19.Qxd7 Qxd7 20.Rxd7 Bd5 21.Bxe5 Rxe5 22.Rdxh7 wins for White.
18...Qe4+?!
I rejected 18...Qxg2 because of 19.0-0-0, but the engines point out 19...Qg4, when Black has good counterplay.
19.Qxe4 Bxe4 20.0-0
Castling long is also good.
20...Bxc2 21.Rac1 Be4 22.Rcd1 Bc6?
White now gets a winning initiative with his kingside pawns.
Correct is 22...Rf7, when White is better but the game is far from over.
23.g4 Rff8 24.f5 gxf5 25.gxf5 Bb5?
Better is 25...Kh8, but 26.fxe6 leaves White on top.
26.Bxb5 Rxb5 27.f6 Bh6 28.Rxd7 (1-0, 41 moves).
