I recently ran across a very short Jerome Gambit game, which allowed me to update some assessments I made of the line, years ago.
Cristopher_Sonido13 - Stefcho2020
3 0 blitz, lichess.org, 2024
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Ke8 6.Qh5+ Kf8 7.Qf7#
Checking The Database showed that I had found 5 previous games that ended the same way.
I was surprised to see that perrypawnpusher - platel, 10 3 blitz, FICS, 2011 was one of them.
Was that covered on this blog? Indeed, yes, 13 years ago.
It is interesting to review what I wrote back then. Modern comments are in red.
6.Qh5+
At the time that I played this move, I knew that the "right" choice was 6.Nxc6, [today's The Database shows 102 games, White scores 73%] since either 6...dxc6 or 6...bxc6 would allow White to play 7.Qh5+ followed by capturing the Bishop; for example, as in perrypawnpusher - rodrigojalpa, blitz, FICS, 2008 (1-0, 25) and Wall,B - Qwerty, chess.com, 2010 (1-0, 9).
Looking at 6.Nxc6 now, I still think that it is best for White, but I wanted to point out two untested responses that might surprise the first player.
a) 6...Bxf2+ (as long as Black is going to lose this piece, he decides to get a pawn for it) 7.Kxf2 Qf6+ 8.Qf3 Qxc6 (avoiding doubled c-pawns) when White is a bit better. He has to be careful because of the loose pawn on c2 and the King and Queen being on the same file (vulnerable to ...Ne7 and ...Rf8).

[Today's The Database shows 4 games with 6...Bxf2+, all wins for White, including one by mwafakalhaswa and two by chessriddler. Stockfish 16.1 shows White to have a winning position.]
Black also has the untried counter-attacking
b) 6...Qh4, (which I mentioned about 3 years ago in this blog) may be better than the capture of the Knight at c6, as well. White's best response is 7.d4, and after 7...Qxe4+ 8.Qe2 Qxe2+ 9.Kxe2 Bb6 material is even, i.e. 10.Nb4 Bxd4.
analysis diagram
[Today's The Database shows 9 games with 6...Qh4, with White winning 4 of them - 44%. Stockfish 16.1 agrees that 7.d4 is White's best response, although after 7...Qxe4+ it slightly prefers 8.Be3 over 8.Qe2, while it still gives White an edge after 8...Qxe2+ 9.Kxe2 Bb6.]
I suppose Black can side-step some of this excitement by capturing the Knight with 5...Nxe5, or by retreating his King to f8, instead of e8, as in the game.
