Tobias Pettersson (2090) - Spanton (1824)
Réti
1.c4 e6 2.Nf3 d5 3.e3
Richard Réti liked to play 3.g3, although there is a game from 1923 when he tried 3.b3. He won the latter game, and scored +7=1-1 with 3.g3 in games in ChessBase's 2023 Mega database.
3...c5 4.b3 d4!?
Stockfish15.1 and Komodo14.1 like this grab of space.

10.b4!?
A common idea in lines of the Réti where Black pushes on with ...d4.
10...Nxb4 11.Nxe5 Qc7?!
The engines strongly dislike this, preferring castling.
12.a3
Also quite promising is 12.Qa4+ Bd7 13.Nxd7 Qxd7 and 14.Qb3 with a slight edge, according to the engines, but not 14.Qxd7+ Kxd7 15.Bxb7? Nc2!
12...Nc6
The engines prefer 12...Na6!?
13.Nxc6 bxc6 14.d3 Rb8?
Grabbing an open file but creating an unfortunate line-up on the h2-b8 diagonal. Again better is castling.
15.Nd2 0-0
Black can prevent Ne4 with 15...f5?, but then 16.Qh5+ is extremely strong.
16.Ne4
The engines point out 16.c5! Bxc5 17.Ne4 with Bf4 to come, and if 17...Rb5 then 18.a4 Ra5 19.Nxc5 Rxc5 20.Ba3 Re5 21.Rxe5 Qxe5 22.Qe1 Qxe1+ 23.Rxe1 etc.
16...Ng6 17.h4 c5?
Better is 17...f6, although the engines reckon 18.h5 Ne5 19.Bf4 gives White the upper hand, eg 19...h6 20.c5 Be7 21.Rc1 Be6 22.Nd2!?, threatening to continue with 23.Nf3 or 23.Qa4.
18.h5 Ne5 19.h6
Even stronger is 19.Nxd6 Qxd6 20.Rxe5! Qxe5 21.Bf4 and 22.Bxb8.
19...Bg4 20.Qd2
This is better than 20.f3 Bf5, after which Black is probably fine.

20...f5??
Black is just about still in the game after 20...Be7 (20...f6 is also much better than the text), eg 21.Qf4 f6 22.hxg7 Rf7, although White has at least the upper hand, according to the engines.
21.Nxd6 Qxd6 22.Qg5 g6 23.Bf4
This wins easily enough, but the engines give 23.Rxe5!, the point being 23...Qxe5 24.Bf4 leads to mate, eg 24...Qe6 25.Bxb8 Rxb8 26.Bd5 etc.
23...Rfe8 24.Rxe5 Rxe5 25.f3 Rb2!?
Desperately trying to create tactical counterplay.
26.Bxe5 Qxe5 27.Qd8+ Kf7 28.Qd7+ Kf8 29.Qg7+
Not 29.fxg4?? Qe3+ with a draw by repetition.
29...Qxg7 30.hxg7+ Kxg7 31.fxg4

31...Rd2?
Now White invades via the open b file. More resistance was put up by 31...fxg4.
The game finished:
32.Bf1 fxg4 33.Rb1 h5 34.Rb7+ Kf6 35.Rxa7 g5 36.Rc7 h4 37.Rc6+ Kg7 38.Rxc5 Kh6 39.Re5 Kh5 40.gxh4 Kxh4 41.Re2 Rxd3 42.Rh2+ Rh3 43.c5!? Kg3 44.Bxh3 1-0
