English 65+ Round One

John Morrish (1644 ECF/1786 Fide) - Spanton (1985 ECF/1922 Fide)
Evans Gambit
1.e4 e5 2.Bc4 Bc5 3.Nf3 Nc6 4.b4
The Evans Gambit is a rare bird in the modern tournament scene.
4...Bxb4 5.c3 Bd6!?
The Stone-Ware Defence is an even rarer riposte - there are just 541 examples of 5...Bd6!? in ChessBase's 2025 Mega database.
How should White respond?

6.d4
This is easily the most popular move, and is liked by Stockfish17 and Dragon1 along with 6.0-0
6...Nf6 7.dxe5!?
The main line in Mega25 runs 7.0-0 0-0 8.Re1 h6!? 9.Nbd2 Re8 10.Bd3!? (10.Qb3 is also popular, and is preferred by the engines) Bf8 11.Nxe5 Nxe5 12.dxe5 Rxe5, with White having full compensation for a pawn, according to the engines.
7...Bxe5
Not 7...Nxe5? 8.Nxe5 Bxe5 9.f4 Bd6 10.e5, and if 10...Qe7 then simply 11.Qe2.
8.Nxe5 Nxe5 9.Bb3
White has the bishop-pair and easy development, but that is not enough for a pawn, according to the engines

9...0-0 10.Bg5
The engines prefer castling, as after the text ...
10...h6
... puts White in a predicament.
11.Bh4
This looks natural, but the engines much prefer giving up the bishop-pair by capturing on f6, or keeping the bishop-pair while maintaining a pin on the black king's knight by 11.f4!? Ng6 12.f5!? Ne5 13.Bh4.
11...Ng6 12.Bg3!?
Offering a second pawn, presumably on the basis that 12.Bxf6 Qxf6 leaves White with no compensation for a single pawn.
12...Nxe4 13.0-0 Nxg3 14.fxg3 d6 15.Nd2 Ne5 16.Qc2 Bd7 17.Rf4 a5!? 18.a3
On 18.Raf1 Black has 18...a4!?, when 19.Bxa4 Bxa4 20.Rxa4 Rxa4 21.Qxa4 Qg5 leaves Black 'only' a pawn up materially, but in a simplified position in which White has queenside pawn-weaknesses.
18...Qe7 19.Raf1 Bb5 20.c4
There appears to be nothing better.
20...Bc6 21.Ne4?
This loses further material

21...Ng6 22.Rg4
Or 22.Nf6+ gxf6 23.Rxf6 Qe3+ 24.Kh1 Be4.
22...h5 23.Rxg6
If 23.Nf6+ gxf6 24.Rxg6+ fxg6 25.Qxg6+, Black has 25...Qg7.
23...Bxe4 24.Qe2 fxg6 25.Re1 Qf6!? 0-1
