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.

Impatient vs Inattentive

Sometimes Black uses the Two Knights Defense to side-step the Jerome Gambit.

Sometimes it does not matter, as the following game shows

thunder_84 - chanegti11

3 0 blitz, lichess.org, 2022

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 

The Two Knights Defense.

4.Bxf7+

Stockfish 16.1 evaluates this position as about a pawn worse for White than it evaluates 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ for White. 

This game brought "impatience" to mind again. I had touched on the topic as recently as 3 months ago, in Jerome Gambit: Impatience 

Four years ago, in the blog post "Unasked Questions" I looked at the Two Knights line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ and commented 

This line doesn't have a name, as far as I know, but it might as well be "the impatient Jerome Gambit". The earliest game that I have with it in The Database is from 2001, but it has to be much older than that. My research is lacking here.

Subsequently (see "Jerome Gambit: Facing Up to 4.Bxf7+ in the Two Knights [Part 2]"), thanks to Dr. Timothy Harding's UltraCorr 3A (2010) collection of correspondence chess games, I uncovered Draper, Dr - Child, AW., Belfast - Dublin team correspondence match-2 1891-2, an earlier game with that "impatient" line.

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Ng6 

7.e5 Nd5 8.Qf3+ 

I suspect that one attraction of playing 4.Bxf7+ in the Two Knights Defense is that an inattentive defender might now slip with 8...Kg8, falling to 9.Qd5 checkmate. There are 89 such games in The Database.

8...Ke6 9.c4 Nb6 

In a 3-minute game it is possible to overlook 9...Bb4+ 10.Kf1 Qh4!? as 11.Qxd5+ can be met by 11...Ke7 and Black's King would be remarkably safe, while his extra piece would outweigh White's two extra pawns, e.g. 12.Nd2 c6 13.Qe4 Bxd2 14.Qxh4+ Nxh4 15.Bxd2 Nf5.

10.d5+ 

White is down two pieces, but this sacrifice leads to victory.

10...Kxe5 

If 10...Ke7 then 11.Bg5+ will win the Queen.

11.O-O 

11...Nxc4 12.Re1+ Kd6 13.Nc3 Qf6 

A slip, perhaps the clock.

14.Ne4+ Black resigned

Black's Queen is lost.

Happy New Year!

 

Dear Readers, 

Here we have an old Soviet New Year's Day postcard. 

The taxis and drivers and cold weather remind me of my own life in the USA, more than a half-century ago. 

Jerome Gambit: Overwhelmed

In the Jerome Gambit, White hopes to quickly overwhelm his opponent with a winning attack on the King.

If the first player is not careful, he can find himself the victim of an attack, as the following game shows.

NB_Chess44 - Mnakib90

10 0 rapid, lichess.org, 2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 

Here we have a typical Jerome Gambit position, as old as Charlick - Mann, correspondence, 1881 (1-0, 72).

The Database has 1,044 examples, with White scoring 63% - despite Stockfish 16.1 rating the position (32 ply) as almost 1 2/3 pawns better for Black.  

10.f4 Ng4 

It is always tempting to attack the Queen.

11.Qf3 

I suspect that White avoided 11.Qg3 because of 11...Qh4 12.Qxh4 Nxh4 but, after 13.O-O that would have been better than the text. 

11...Qh4+ 12.g3 Qh3 

13.Nc3 

Black's Queen is up to no good, and White needed to address that immediately with 13.Qf1, even though exchanging Queens would reduce his attacking chances.

13...Rf8 

This move is good, but 13...Nxf4!? would cause even more problems after 14.Qxf4 Rf8. 

14.d4 Nh4 White resigned

Black's force on the Kingside is overwhelming, and he will break through, e.g

If 15.Qe2, then 15...Ng2+ 16.Kd2 Nxf4 17.gxf4 Rxf4.

Or 15.Qf1 Ng2+ 16.Ke2 g5.

Jerome Gambit: I'm Not Supposed to Win Stuff Back

The TikTok video "Jerome Gambit in 8 Moves" by OffbeatGambits presents Eric Rosen playing a Jerome Gambit, 

The point is that I win stuff back, kind of... I'm not supposed to win stuff back, but... Wow, I won in 8 moves in the Jerome...

The game was previously shown in the blog post which featured Eric's "Winning as Quickly as Possible with TRICKY Gambits".

For that matter, "Jerome Gambit: Gambit Duel (Parts 1, 2, 3 & 4)" showed Eric defending against the Jerome.

Fun stuff.

Jerome Gambit: Ever Wins

 

The YouTube video, THE INSANE JEROME GAMBIT EVER WINS, by Cortez Chess, is less than a minute in length, but ends with a video clip that humorously illustrates how someone feels after losing to 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

Have a look.

Jerome Gambit: A Bit of A Puzzlement

I can figure out some Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games, but certainly not all of them.

The following game is a bit of a puzzlement, especially the end.

Perhaps a Reader can explain it.

Robov - sajadbahar

15 10 rapid, lichess.org, 2023

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 g6

White should have been happy with this move. There are 174 games with it in The Database. White scores 75%. 

8.Qxe5+ Kf7 9.Qxh8

Capturing the Rook is not much weaker or stronger than capturing the Bishop. 

9...Qh4+ 10.g3 Qh3 11.Qc3 

Pulling the Queen back. Later in the year, Robov tried 11.d4 Qg2 12.Rf1 Bb4+ 13.c3 Qxe4+ 14.Kd1 Qd3+ 15.Bd2 Qxf1+ 16.Kc2 Bf8 17.Qxh7+ Bg7 18.Qh4 d5 19.Qg5 Bf5+ 20.Kb3 Qf2 21.g4 Bxb1 22.Qxd5+ Kf8 23.Qc5+ Ne7 24.Rxb1 Qxd2 25.Rf1 Qg2 26.f5 Qxf1 27.fxg6 c6 28.h4 Qb5+ 29.Qxb5 cxb5 White resigned, Robov - Omgl, lichess.org, 2023. 

White's best move here might have been the novelty 11.f5!?, hoping to open the f-file against the enemy King. That would have convinced Stockfish 16.1 that the first player was better, while the text move supports the second player. 

11...Qg2 

Black's Queen slips behind enemy lines.

12.Qc4+ 

Rolling the dice, as the alternative, 12.Rf1 Qxe4+ 13.Kd1 d5 is clearly worse for him. 

12...Ke8

In turn, Black falters. With the thematic 12...d5 he could have stayed on top. 

However, here White resigned. This was unfortunate, as he had the obvious 13.Qxg8+, or 13.Rf1 d6 14.Qxg8+, or even 13.Qf1 Qxe4+ 14.Qe2, in each case with advantage.
