New Year - New Championship

THE top division of the Battersea club championship got underway last night, with me paired against reigning champion Paul Stokes.
Stokes (158) - Spanton (168)
Catalan/Dutch Stonewall
1.Nf3 d5 2.d4 e6 3.g3 c6
Not liked by Stockfish10 or Komodo10, it is a viable option and has been chosen by grandmasters. The main moves are 3...Nf6 and 3...c5.
4.Bg2 f5 5.0-0 Nf6 6.c4 Be7
Magnus Carlsen has played the much more popular 6...Bd6.
7.b3 0-0 8.Ba3!?
Exchanging dark-square bishops is the main plan, but is strongly disliked by the engines. I guess they regard it as too time-consuming.
8...Bxa3 9.Nxa3 Qe7 10.Nb1
More popular are 10.Nc2 and 10.Qc1!?
10...Ne4 11.Nfd2!?
The main line goes 11.Qc2 Nd7 12.Nbd2, when Black is at least equal, according to the engines.
11...e5!?
Probably a new move. The engines prefer the known 11...Nd7.
12.Nxe4 fxe4?
An 'automatic' move played much too quickly. Black seems fine after 12...dxe4, when the engines continue 13.Nc3 Rd8 14.d5 with an unclear but roughly equal position.
13.cxd5?!
White poses more problems with 13.Nc3 according to the engines. They continue 13...Be6 14.dxe5 Rd8 15.Qd4 dxc4!? 16.Qxe4, giving White the upper hand.
13...cxd5 14.Nc3 Be6?
Better is 14...Rd8 15.dxe5 Nc6 (not 15...Qxe5?? 16.Nxe4) 16.Rc1 Qxe5.
15.dxe5 Rd8 16.Rc1
Not 16.f4?? Qc5+.
16...Nc6 17.Nb5
Also strong is 17.f4.
17...Nxe5 18.Nc7 Rac8?
Black had to play the modest 18...Rab8.

How should White proceed?

19.Nxe6?
19.Nxd5 wins substantial material, eg 19...Qf7 (or 19...Rxd5 20.Rxc8+) 20.Rxc8 Bxc8 21.Bxe4.
19...Qxe6 20.Qd2 Nc6 21.Qe3 Re8 22.f3 Rcd8 23.fxe4 d4!?
23...dxe4 24.Rc4.
24.Qd2 Ne5 25.Qg5 d3?!
The engines prefer 25...h6 26.Qf5 Qe7 with reasonable, if not complete, compensation for a pawn.
26.exd3 Nxd3 27.Rc2 Qb6+ 28.Kh1 Re5 29.Qg4 Ree8 30.Qe2 Ne5
Black's threats are over.
31.Rd1 Qa5?!
Almost certainly better is 31...Rxd1+ 32.Qxd1 h6, asking White how he will break the blockade.
32.Rd5 Qb6 33.Rxd8
Activating the bishop with 33.Bh3 is natural, but White is also much better after the text.
33...Rxd8 34.Rd2 Rc8 35.Bh3 Rc1+ 36.Rd1 Rc3?
Missing White's reply. After 36...Rxd1+ 37.Qxd1 Qc6 Black still has defensive chances.
37.Qh5 Nf7
Not 37...Ng6? 38.Qd5+ Kf8 39.Rf1+.
38.Qd5 Qc6?
But 38...Rc5 39.Qe6 Qxe6 40.Bxe6 Kf8 41.Rf1 Rc7 42.Kg2 also wins.
39.Be6 Qxd5 40.exd5 Kf8 41.Rf1 1-0
