The move ...d5, without first playing ...d6, is thematic in the Accelerated Dragon, and 8...d5!? here is also the top choice of Stockfish19 and Dragon1.
9.exd5 Na5 10.0-0
A main line has yet to be established, it is probably fair to say, but this is the most popular continuation in Mega26, and scores an excellent 64%.
10...Nxb3 11.Nxb3
11.axb3!? has been played, but Black immediately regains the pawn with 11...Nxd5.
11...b6 12.d6!?
The engines agree with giving the pawn back, but saddling Black with an isolani.
12...exd6 13.Qf3 Bg4 14.Qg3 Bh5?!
Apparently a novelty, and almost certainly not a good one. Known moves are 14...Bf5 and 14...Rc8.
15.Bd4
The unsubtle 15.f3!? is also strong.
15...Re8
This is Dragon1's top choice, at least for a while, but better may be 15...h6 16.f3!? g5!?, although the engines reckon 17.f4!? gives White a positionally won game.
16.f3!? Qd7?
Reducing the protection of f6 causes Black big problems. Perhaps best is 16...Rc8!?, and if, as in the game, 17.Qh4, then 17...Rc4, as 18.g4? Rxd4! 19.Nxd4 Nxg4! 20.Qxd8 Bxd4+ 21.Kh1 Rxd8 22.fxg4 Bxg4 23.Rf4 Bxc3 24.bxc3 Bf5 sees Black emerge with two pawns for the exchange, and the much better pawn-structure, the engines reckoning Black would enjoy the upper hand. However, White improves with 18.Rae1, gaining at least the upper hand, according to the engines.
17.Qh4

17...Re6
There is nothing better.

20.f4!
This looks double-edged as every white kingside pawn advance leaves White's king a little more vulnerable, but the engines agree it is best, although Dragon1 also likes 20.Qd2!?
20...h6 21.Qh4 Rae8?
The engines prefer 21...Bxc2, when 22.f5 forces Black to give up the exchange with 22...Re5.
22.f5 Re4!? 23.Nxe4 Rxe4 24.h3

24...Bxf5!? 25.Bxf6 Bxf6 26.Qxf6 Bxg4 27.Kh2!?
Simplest is probably 27.Rf4, but the text is plenty good enough.
27...Bxh3 28.Qf3!? Qe6
There is no perpetual, let alone checkmate, after 28...Bxf1 29.Qxf3 Qh3+ 30.Kg1.
29.Rf2 Re3 30.Rg1+ Kf8 31.Qa8+ Ke7 32.Qxa7+ 1-0
