Jerome Gambit: Not the Gutter, Again


Should White take time to grab the enemy b-pawn? Is the material worth the time or distraction?

It depends. In the following game, angelcamina says "No, thank you" and continues to work on winning the enemy King, instead.

Jerome Gambit: Wikipedia



As a companion post to the previous one (see "Jerome Gambit: I Suppose That It Had to Happen Eventually"), I checked, and found that Wikipedia still has its article on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), including the reference



IM Gary Lane's articles have comments about the Jerome Gambit. His "Opening Lanes" were always worth a look.

It is important to note that the Wikipedia article is a look at early history of Jerome gambit - the end of the 19th century. Theory and practice have advanced quite a bit, this blog being one example.

Jerome Gambit: I Suppose That It Had to Happen, Eventually



I suppose that it had to happen, eventually.

To keep up with things Jerome, I set up a Google Alert for "Jerome Gambit". It has linked me to games, videos and articles.

Most recently, it has linked me to this blog.

What goes around, comes around, I guess.

Jerome Gambit: Training Game #10

                        

Here is another Jerome Gambit game, as I have noted,

From a webpage about the Russian-language chess book, Gambit, by Natalia Ryabova ["A book about gambits as a way of playing. It covers both popular and rarely encountered gambits in tournament practice. For a wide range of chess fans." - Google translate]

NN - NN

#10 Training Game, Gambit, Ryabova

2024

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 


The Database has 713 games with this position, with White scoring 61% - although Stockfish 16.1 (35 ply) evaluates the position as about 1 1/2 pawns better for Black.

These numbers remind me of a series of posts on this blog from over a dozen years ago. I wondered, was playing the Jerome Gambit a help or a hindrance for me? Check out "The Jerome Gambit: Helping or Hurting?", "Furthermore", "And Then", and "Still".

10.O-O 

Or 10.h4!? as in NN - NN, 2024 (1-0, 43), see "Jerome Gambit: Training Game #6". 

10...Qe8

Instead, 10...Kf7 was seen in Vazquez,A-  Carrington,W, Mexico, 2nd match, 1876 (1-0, 34). 

11.Nc3 Be6 

Or 11...Kf7, as in NN - NN, 2024 (1-0, 34), see Jerome Gambit: Training Game #5.


The position of Black's Bishop and Knight (at g6) encourages White's next move, and Black's response to that causes difficulties.

12.f4 Ng4 

Yielding to temptation, attacking the enemy Queen. The discreet 12...Ne7 was more in line with the position. 

13.Qg3 Kf7 

Hoping to castle-by-hand? Acceding to the return of a piece? There is too much enemy firepower nearby for this to be successful.

14.f5 Bc4 15.fxg6+ Kg8 16.Qxg4 Bxf1 17.Kxf1 Qxg6 18.Qxg6 hxg6 


The smoke has cleared, and White has two pieces and a pawn for a Rook.

19.Kg1 Rh5 20.d3 Rd8 21.h4

Cute, if now the incautious 21...Rxh4, then 22.Bg5 would fork both enemy Rooks.

21...Rd7 

22.Bg5 Rh7 

This Rook can't seem to stay out of trouble.

23.g3 c6 24.Kg2 Rh5 25.a4 Rf7 26.Ne2 Kf8 27.Nf4 Rh8 28.Nxg6+ Ke8 

29.Re1 

White decides upon a center pawn break (or advance).

There was nothing wrong with 29.Nxh8 - which never happens.

29...Kd7 30.e5 Rf5 31.g4 Rxg5 32.e6+ Kd8 33.hxg5 


My guess is that the clock was a factor at this point. Otherwise, why continue? White's advantage is overwhelming.

33...d5 

Just move?

White now has a forced checkmate.

34.e7+ Ke8 35.Rf1 Kd7 36.Rf8 Kc7 37.e8=Q 

37...Kb6 38.Qd8+ Ka6 39.b4 Rh2+ 

Spite check? Hoping for an eventual, unlikely stalemate??

40.Kxh2 b5 41.Qc8+ Kb6 42.a5 checkmate

Jerome Gambit: Black Overlooks Something


Tactical awareness is paramount in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

When the defender makes a slip, the attacker must pounce.



Amir_hou_Ma - olgaKIRILL2016

10 5 blitz, lichess.org, 2025

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke7 

The Paulsen variation - creative, surprising, and favoring White. The Database has 47 games with this line. White scores 72%

6.Nxc6+ 

White exchanges his Knight, with check. 

Stockfish 16.1 suggests, instead, 6.Qh5 Bxf2+ 7.Kxf2 Qf8+ 8.Nf3 Nf6 

6...dxc6 

7.O-O Nf6 8.e5 Nd5 

This looks reasonable and standard, but Black overlooks something.

9.d4 Bb6 10.Bg5+ Black resigned

Jerome Gambit: 2600+ vs 2600+


Both players in the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) are rated 2600+.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

This counter-attack goes back at least to Sorensen - X, Denmark, 1888 (1-0, 27).

7.O-O d6

Black prefers to focus on development, instead of grabbing a pawn with 7...Qxe4, although the capture is a bit better.

Black casually goes about his game.

11...Bg4 

Black adds yet another piece to the attack. But is g4 the right square?

12.Qb5 


White's Queen abandons the Kingside defense for counter-attack on the Queenside. It looks risky.

12...Nc6 13.Qxb7 Rb8

The tactics are heating up. Stockfish 16.1 recommends 13...Be2 14.Qxc7+ Rd7 15.Qxc6 Bxf1 16.Bd2 (not 16.Qxa8 Ng4 and mate in 4) Re8 17.e5 Re6 18.Qf3 Ba6

White has three pawns for the exchange.

After the exchange of Queens, White's advanced d-pawn will fall, but he will remain a piece and a pawn ahead.

Jerome Gambit: Ten Move Checkmate


The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is a 10-move win, by checkmate.

It is another light-hearted answer to the question Why play the Jerome?

Whew! To summarize, after 9...Qg6, White's best move is 10.Qe2.

Oh, and of course, after 9.fxe5, as in the game, Black can not recapture with 9...Qxe5 because of  10.Qf7 checkmate. 

But 9...Qe7 leads to a quick end.

10.Qf5 checkmate

Regular readers of this blog may notice that this checkmate appears familiar. Indeed, it is similar to the end of Idusha2010 - Egor_Shtanko. 30 0, lichess.org, 2022.
