10.d3
The main move is 10.Re1, preventing 10...e5.
10...e5 11.Ba3?!
This has been played by a 2268, but initiating a swop of dark-square bishops seems strange.
11...Bxa3!?
Hoping the queen's knight will be misplaced on a3, but it was perhaps better to let White swop.
12.Nxa3 Bf5 13.Nh4 Bg4 14.Qd2 Re8 15.h3 Bh5!?
Stockfish15 and Komodo13.02 much prefer 15...Be6 or 15...Bd7.
16.Rfe1 Qd7 17.Kh2!?
The engines strongly dislike this, preferring 17.c5!?
17...Re7!?
Here the engines suggest 17...h6.
18.b4 Rae8 19.c5
How should Black proceed?

19...Nd5?!
Best, according to the engines, is the consistent 19...e4.
20.Nc4 Ncxb4?
Possibly best is 20...Nc3, but 21.Nd6 leaves White on top.
21.Nd6 Rb8?
Black should give up the exchange.
22.a3 Na6 23.Bxd5 Nxc5 24.Nhf5 Re6
There is no defence.
25.Qg5 Bg6 26.Bxe6 Nxe6 27.Ne7+ Kf8 28.Nxg6+ hxg6 29.Qxe5
White emerges up a rook for a pawn.
The game finished:
29...Rd8 30.Nc4 Re8 31.Rab1 f6 32.Qd6+ 1-0
