Jerome Gambit: Peering Back

Today I was peering back at Jerome Gambit: A New Look at an Older Line, where I looked at the game 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#

Here are some of my comments, with updates, and updates of updates...

It is interesting to review what I wrote back then. Modern comments are in red. [Today's 2025 comments are in pink.]

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% { In 2025, this is now 110 games, White scores 72%}] 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. {Unchanged in 2025}]

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.

The Database in 2025 has 9 games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Ke8 6.Nxc6 Qh4, with White scoring 4 - 5. 

Thus, 6...Qh4 remains the strongest response for Black to 6.Nxc6. Stockfish 16.1 agrees, assessing the position as slightly better (+/=) for White.
