Chumpionship Chess

PLAYED in the Battersea club championship last night.

Venerando Bermudez (1599) - Spanton (1971)
Jobava-Prié
1.d4 d5 2.Bf4 e6 3.Nc3 Bd6 4.Bd2?!
White can get away with a retreat like this in the opening, thanks to having the first move. By "get away" I mean such a move can be played without dire consequences; nevertheless Black is already at least equal.
4...Nf6 5.e3 Nbd7 6.Bd3 e5
The game resembles, with colours reversed, a French Defence, but one with questionable play.
7.f3?!
Preventing, or at least delaying ...e4, but weakening the white kingside.
7...0-0 8.Nge2 Re8 9.0-0 e4?!
Probably premature. After ...
10.fxe4 dxe4 11.Bc4
... Black has gained space but White has a half-open file for the king's rook and an improved diagonal for the light-square bishop.
11...Nb6 12.Bb3 Bg4
Not 12...Bxh2+?? 13.Kxh2 Ng4+ 14.Kg1 Qh4 as the white king escapes checks easily enough and meanwhile Black's f and e pawns are vulnerable. However possibly better than the text is 12...Be6, relieving pressure on f7.
13.Be1 a5!?
Stockfish15 and Komodo13.02 strongly dislike this, reckoning Black is slightly better after 13...c5.
14.a4 c5 15.Bh4 c4 16.Ba2 Re6?
Simpler and better is 16...Be7.
17.b3?
White is well on top after 17.h3, according to the engines.
17...Bxe2?
Giving up the bishop-pair and developing the white queen. Black has an edge after 17...Bb4, according to the engines.
18.Qxe2 Qc7?
Still best is ...Bb4, according to the engines, but by now they much prefer White.
19.Nb5
Also strong is 19.dxc4.
19...Bxh2+ 20.Kh1 Qb8 21.bxc4 Bg3
Or 21...Nbd7 22.c5, eg 22...Rc6 23.g4!
22.Bxf6 Rxf6 23.Rxf6 gxf6 24.c5
What should Black play?

24...Nd7?
This loses trivially, but not much better is 24...Nxa4, eg 25.Qh5 Qf8 26.Bd5 f5 27.Qg5+ Qg7 28.Qxg7+ Kxg7 29.Rxa4.
25.Qg4+ Kh8 26.Qxd7 (1-0, 38 moves).
