Catastrophe In The Opening

IAKOV Neishtadt compiled Catastrophe In The Opening, which was translated by Kenneth Neat as a Pergamon book in 1980.
If a later edition were to be published, the following game, played on board three (of eight) in division one of the London League last night, could be a candidate for inclusion.

Spanton (1976 - Battersea) - Seny Denisov (1830 - Imperial College)
Sicilian Accelerated Dragon
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3
From a Hyper-Accelerated move-order, the game has transposed to the main non-Maróczy Bind line of the Accelerated dragon.
5...Nc6 6.Nxc6!? bxc6 7.Bc4 Nf6?!
The mainline in ChessBase's 2023 Mega database runs 7...d6 8.0-0, and then 8...Nf6, with an equal game according to Stockfish15 and Komodo13.02.
8.e5 Ng8
The engines give 8...Ng4!? 9.Qxg4 d5, claiming White has only a slight edge.
9.Qf3 e6
9...f5 is, at best, a tiny improvement, according to the engines.
10.Bf4 Qa5 11.Qe2?
I rejected 11.0-0-0 because of 11...Bxe5 12.Bxe5 Qxe5 13.Rhe1, when Black, although massively behind in development, has an extra pawn and the only central pawns. However that is how a game of mine went at the 2019 South Wales Open in Bridgend, and the engines reckon White is well on top.
How should Black proceed?

11...d5!
Only one of four games in Mega23 to reach the diagrammed position saw 11...d5!, but it gives Black the advantage.
12.0-0-0?
Not 12.exd6? Bxc3+ etc, but missing that 12.Bb3 d4? can be met by 13.Qe4 (or 13.Qc4), when the advantage has swung back to White. Instead the engines reckon 12...Ne7 gives Black at least a slight edge.
12...dxc4 13.Qxc4?!
The engines prefer 13.Ne4!? or 13.Qd2.
13...Ne7 14.Bg5 Ba6 15.Qd4 Nd5 16.Ne4 0-0 17.c4 Nb6 18.Nf6+ Bxf6 19.Bxf6
White is three tempi from delivering mate, but that is far too long

19...Qxa2 20.b3 Qxb3 21.Qd2 Qxc4+ 22.Kb1 Nd5 23.Ka1 Qa4+ 0-1
Battersea won the match 4.5-3.5.
