Benidorm U2000 Games: Round Three

PLAYED on Monday.

Bob Holliman (1946) - Spanton (1829)
London System
1.d4 d5 2.Nf3 Nc6 3.Bf4 Bg4 4.Nbd2 e6 5.e3 Bd6 6.Bg3 Nf6
Possible is 6...e5!?, which is a main objective behind Black playing a Pseudo-Chigorin set-up.
7.Be2 0-0 8.0-0 Re8?!
Having missed the chance to get in ...e5, there is little point in putting the king's rook on the e file. Komodo12.1.1 suggests 8...Ne7!?, claiming equality, while Stockfish14.1 gives 8...Bxg3 9.hxg3 Nb8!?, awarding White a slight edge.
9.c4 Ne7 10.Ne5 Bxe2 11.Qxe2 Nf5 12.f4?!
This does White's bishop no favours and makes e3 weak.
12...h5
Good for Black, according to the engines, is 12...c5, when White is more-or-less obliged to play 13.dxc5 Bxc5 14.Bf2, with advantage to Black.
13.Bf2 c6 14.c5 Bxe5 15.fxe5
The engines slightly prefer 15.dxe5!?, meeting 15...Ng4 with 16.e4.
15...Ng4 16.h3
Now 16.e4 can be met by 16...dxe4 17.Nxe4 Nxd4, winning a pawn, although White has some compensation (but not enough, according to Stockfish14.1; sufficient, according to Komodo12.1.1).
16...Nxf2 17.Rxf2 Qg5 18.Re1
How should Black proceed?

18...h4?!
This is weakening, according to the engines; they reckon 18...b6 favours Black.
19.Rf3?!
BH moved the rook to f4, without letting go of the piece, then dropped it back to f3. He explained after the game that he somehow thought the rook would be en prise on f4.
19...Rf8 20.Rf4 f6 21.Rg4 Qh6 22.exf6 Rxf6 23.Nf3 Raf8 24.Qd3 Rg6 25.Ne5 Rxg4 26.Nxg4 Qg5
How should White proceed?

27.e4?
At first glance it looks logical to open the e file for White's rook, but better is a move such as 27.Rf1 or 27.Qb3, in both cases with equality, according to the engines.
27...Ng3 28.exd5 exd5 29.Ne5 Qf4 30.Nf3 Ne4 31.Qe3 Qg3 32.Ne5?
Correct is 32.Rd1 or 32.Re2, according to the engines, but Black maintains pressure.
Black to play and win

32...Qxe3+?
Missing 32...Rf2 33.Qxg3 hxg3 34.Rb1 (34.Nd3 Rd2 35.Re3 Rd1+ 36.Ne1 Rxd4) Rc2 35.Nf3 Nd2 36.Nxd2 Rxd2 and ...Rxd4.
33.Rxe3 Ng3
Not 33...Rf2?? 34.Rxe4.
34.Nf3 Nf5 35.Re6 Rf6 36.Re8+
There is no progress to be made on the kingside after 36.Rxf6 gxf6, but White must be slightly better and can try expanding on the queenside.
36...Rf8 37.Re6 ½–½
