Alistair Hill (2190) - Spanton (1889)
Pseudo-Chigorin
1.Nf3 Nc6 2.d4 d5 3.g3 Bg4 4.Bg2 Qd7 5.0-0!?
More popular is 5.h3 to avoid ...Bh3, but Stockfish15 and Komodo13.02 prefer the text.

5...h5!?
The mainline runs 5...0-0-0 6.c3 (6.c4 is also common) f6 7.b4 with advantage to White, according to the engines, which reckon 5...Bh3 6.c4 Bxg2 7.Kxg2 e6 also favours White.
6.c4 Bxf3?!
This may be a novelty. Known moves are 6...e6 and 6...e5?, while 6...dxc4 7.d5 0-0-0?! 8.Nc3 strongly favours White, according to the engines.
7.Bxf3 h4?
Better is 7...dxc4, and if 8.d5 then 8...Ne5.
8.cxd5 Nb4
I had originally intended 8...hxg3 9.hxg3 Qh3, missing the simple 10.Re1, and also missing that White could play 9.fxg3 Qh3 10.Rf2.
9.Qb3 e6 10.dxe6 fxe6 11.Bd2 Nd5?
As AH pointed out in the postmortem, better is 11...a5, meeting 12.a3 with 12...a4.
12.Qxb7
Preventing long castling as well as grabbing a pawn.
12...Rd8 13.Nc3 hxg3 14.hxg3 Ngf6 15.Bg5 Be7 16.e4 Nxc3 17.bxc3 e5 18.Bg2
The engines point out also possible is 18.dxe5 as 18...Qh3 19.Rfd1 Ng4 can be met by 20.Qc6+ Kf7 21.Qc4+ Ke8 22.Rxd8+ Bxd8 23.Qe6+ Kf8 24.Bg2 Qh2+ 25.Kf1 Bxg5 26.Rb1. If in this line 21...Kg6 then 22.Qe6+, eg 22...Kxg5 23.Qf5+ Kh6 24.Bxg4.
18...0-0 19.dxe5 Ng4 20.Qb3+ Kh8 21.Rad1 Qe8 22.Rxd8 Bxd8 23.Bxd8 Qxd8 24.Qe6
White has a massive advantage.
The game finished:
24...Nxf2 25.Rxf2 Qd1+ 26.Bf1 Rxf2 27.Rxf2 1-0
