Jerome Gambit: Carelessness


The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a chess opening with a list of refutations. Yet, it is growing in popularity among club players who not only like the exciting play it produces - they like the wins the Jerome brings as well.

How does someone lose to a refuted opening? There are many ways, but a major one is carelessness.

The following game is a good example of the defender's position being better, right up to the point where he is checkmated.

It is also a good example of White being constantly alert, making threats, and taking advantage of his opportunities.

Jerome Gambit: The Proper Medicine

After an interesting opening, White outplays his opponent in the following game. Solid strategy and effective tactics can cure even the most "refuted" of openings.

Emit79 - dimbenes1

10 0 blitz, Chess.com

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 


The Semi-Italian Opening.

4.Bxf7+ 

This is one of what I call the "impatient Jerome Gambit", lines where White does not wait for ...Bc5 before sacrificing his Bishop. It gains in immediacy of surprise, but lacks a target on c5 that sometimes allows White to recover some material.

Both 4.0-0 Bc5 5.Bxf7+ and 4.Nc3 Bc5 5.Bxf7+ are referred to at the Semi-Italian Jerome Gambit.

4...Kxf7 5.Nxe5+ Nxe5 

Black survived the odd 5...Ke7 with 6.O-O (6.Ng6+) Nf6 (6...Nxe5) 7.d4 (7.Nxg6+) Nxe5 8.dxe5 Nxe4 9.Qg4 d5 10.exd6+ Qxd6 (10...Nxd6) 11.Qxe4+ Be6 12.Bf4 Qb6 13.b3 Rd8 14.Nc3 Kd7 15.Rad1+ Kc8 16.Rxd8+ Kxd8 17.Rd1+ Kc8 18.a4 Bc5 19.Nb5 Bxf2+ 20.Kh1 Re8 21.c4 (21.Nxc7) a6 (21...Bd7) 22.a5 (22.Nxc7) Qc5 (22...Qc6) 23.Nxc7 Rf8 24.Nxe6 Re8 Black won on time, MrBizkit - erkhestheasswhooper, 3 0 blitz, Chess.com, 2020.

6.Qh5+ Ke7 


Also seen recently was 6...g6 7.Qxe5 Nf6 8.Nc3 d6 9.Qf4 Bg7 10.b3 Qe7 11.Bb2 Kg8 12.f3 Ng4 13.O-O Ne5 14.Nd5 Qd7 15.Nf6+ Bxf6 16.Qxf6 Qb5 17.Bxe5 Qc5+ 18.Kh1 dxe519.Qxg6+ Kf8 20.Qf6+ Kg8 21.f4 Qd4 22.fxe5 Qxe4 23.Qf7 checkmate, Taymur - NarvalAlbatre, 5 0 blitz, lichess.org, 2020. 

Black did better with 6...Ng6 (there is no Bishop to capture on c5, see the note to move 4) 7.Qd5+ Ke8 8.O-O N8e7 9.Qh5 d6 10.Nc3 Be6 11.d3 c6 12.Be3 d5 13.exd5 Nxd5 14.Qxg6+ Kd7 15.Nxd5 cxd5 16.c3 Qf6 17.Qg3 g5 18.c4 dxc4 19.dxc4 Bd6 20.Rfd1 Ke7 21.Qxd6+ Kf7 22.Qc7+ Qe7 23.Rd7 Bxd7 24.Bc5 Qd8 25.Qd6 Qe7 26.Qd5+ Be6 27.Qf3+ Qf6 28.Qxb7+ Kg6 29.Re1 Rab8 30.Qe4+ Bf5 31.Qd4 Rhe8 32.Qxf6+ Kxf6 33.Rxe8 Rxe8 34.Bxa7 Re1 checkmate, vrajeshpadiyar - petrochemicals, Chess.com, 2020

7.Qxe5+ Kf7 


Now "objectively" best is 8.Qf5+ Ke7 9.Qe5+ Kf7 10.Qf5+, etc., with a draw by repetition.

8.d4 d6 9.Qh5+ Ke7 10.Nc3 Nf6 11.Nd5+ Nxd5 12.exd5 Qe8

13.Qh4+ Kd7+ 14.Be3 Be7 15.Qg4+ Kd8 16.Qe2 Bf5 17.O-O a6 


White has two pawns for the sacrificed piece, and his King is a bit safer than Black's. Whose attack will succeed?

18.Qc4 Kd7 19.Qa4+ Kc8 20.Qb4 Kb8 21.c4 Ka7 22.c5 Rb8 23.Rfe1 Ka8 24.a4 Qg6 

25.Bf4 Rhf8 

This looks like a mouse-slip.

26.Rxe7 Be4 27.Bg3 Rf5 28.Re6 Qg5 29.Rxe4 Rbf8 

Black has his heavy pieces in place, but White's attack arrives first.

30.a5 h5 31.c6 bxc6 32.dxc6 Rb5 33.Qc4 

A slip that his opponent doesn't notice. Better was 33.Qc3. Now Black has 33...d5.

33...Rh8 34.Rae1 h4 

35.Bf4 Qg4 36.Qf7 h3 37.Re8+ Rxe8 38.Rxe8+ Ka7 39.Qxc7+ Rb7 40.Qxb7 checkmate

Jerome Gambit: Unravelling A Mystery

 



I receive many Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games from generous readers of this blog, mostly via email.

Sometimes the email contains a link to the chess website where the game was played, so I can go there and obtain a pgn file of it. Sometimes the email contains the pgn file itself.

Occasionally, the reader includes the raw moves of the games. A few times, I have received videos of the game - and I have been able to watch them, and write down the moves myself.

All of these contributions help build The Database, my collection of over 62,700 Jerome Gambit and related games. (For example, there are almost 15,500 games with the original move order; over 2,700 games with the Italian Four Knights Jerome Gambit; about 6,450 games with the Blackburn Shilling Jerome Gambit; and that's just a sample.)

A while back I received an email with a game's moves and the names of the players. One move was ambiguous, and I wrote the reader a couple of times for clarification, as the game was quite interesting, either way. Alas, I have not heard back. I would like to present the game, anyhow.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 

Here is the confusion, already. The move, as sent, was "3...b5". 







I am not sure what to make of the game, if that is not a transcription error. On the one hand, White can simply play 4.Bxb5, winning a pawn in an odd Ruy Lopez. I actually found 15 games with 3...b5, and White scored 13 - 1 - 1 - not exactly a result that calls for an improvement  in the line.

On the other hand, the Jerome Gambit has a way of upsetting everything, so it's not impossible that the reader played a novelty, 4.Bxf7+, and saw the game continue 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe8 







Here, White can capture a Rook, with advantage - 8.Qd5+ followed by 9.Qxa8.

However, the game continued with the capture of the other Rook, 8.Qxh8 - and Black resigned, unaware that he had the brutal 8...Qxe4+, similar to the counter in Whistler's Defense. One line would be 9.Kf1 Bg7 10.Qxh7 Qxc3 11.Nc3 b4 and White is going to lose more material.

That is interesting, in and of itself, but what if Black had actually played 3...Bc5 ?

4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Qe8 


The Database has only one example of 7...Qe8. See Role Reversal.

Moving Black's Queen to the e-file is similar to the idea behind Whistler's Defense, although in that line, 7...Qe7, the Bishop is defended.

White should now pick up the Bishop, with an edge, after 8.Qxc5 Qxd4+ 9.Kf1. Instead, he went after the Knight.

8.Qxh8 Black resigned


Instead, with 8...Qxe4+, Black could have transposed into Whistler's Defense, with a clear advantage. Once recent example can be seen in "Jerome Gambit: Scared Silly"

So, whichever way the game actually went, Black wound up with a significant advantage, but he resigned, anyway. How very Jerome!

Jerome Gambit: In the End, A Win

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game is a hard-fought battle, as both players work to make something out of a relatively balanced position. At first, White makes progress, but the clock seems to undo that. Then, Black's chances slip by. Finally, in a drawn position, the defender makes one last play - and then must surrender the full point.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+ 


Along with several Readers, I have begun to think of this line as a "double Jerome Gambit". It is often used as a psychological counter gambit by Black, with a return of material leading to a forced exchange of Queens, blunting White's attack.

In this game, however, Black prefers to keep the Queens on the board, so perhaps his move choice was based on "You sacrificed a Bishop to keep me from castling, so I will do the same to you".

The position is not an exciting one, but White has an extra pawn to work with.

White is a piece and a pawn ahead. He just has to find a plan to make it all work.

24.h3 Kg5 25.g4 Bd7 26.Re5+ Kh4 27.Re7 Bc6  28.Rxh7+ Kg3 29.Bd6+ Kf3 30.Nd4+ 

Missing 30.Re7, and then 31.Nd4#.

30...Ke3 31.Nxc6 Rxc6 32.Bxb4 Rxc2

Black now manages a bit of counter play, but it is nothing that White can not handle.

39.Rxg6 d3 40.Rd6 Ra2+ 41.Ke1 Ra1+ 42.Kd2 Ra2+ 43.Ke1 Rh2 


Black adds threatening the enemy pawns to his plan to advance his passed pawn. White's Bishop should help hold things together, however.

44.Rh6 Kf3 45.g5 d2+ 46.Kd1 Ke3 47.Bc5+ Kd3 48.Rd6+ Kc3 49.Rxd2  

This looks like a time error. Instead, 49.Bd4+ Kb4 50.g6 Rxh3 51.g7 Rg3 52.Kxd2 is how to use his advantages and advance to the win.

49...Rxd2+ 50.Kc1 Rg2 51.Be7 Kd4 


Black pursues the draw, instead of the win with 51...Rg1#. This has got to be due to a shortage of time.

Black has effectively blockaded the pawns and kept the enemy King at bay. A draw would be an honorable result.

63.Ke3 Rc4 64.Kd3 Rh4 65.Ke3 Rg4 66.Kf3 Ra4 67.Ke3 Ra6 68.Kf4 Rxf6+ 

A miscalculation. White's King is one step too close to the pawns.

Jerome Gambit: More Research


More research from Dan Watson on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). His source is The Earth (Burlington Vt)  January 7, 1899, page 8. 

I have added diagrams. My notes are in blue - Rick.


Barnett - Gingras

Vermont, 1899


The game between Barnett of Burlington and Gingras of Winoski resulted in a win for the latter, showing that the Jerome gambit is too hazardous when the opponent is a strong player, as Mr. Gingras is, and the loss of the bishop and knight at the outset, can not be compensated for by the advantages of position. Following is the game.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 


The usual continuation here is 6.Qh5+ and is probably better than 6.d4

6...Qh4 

Well played, leading to a strong defense.

I have only one earlier example of this line in The Database, Sorensen - X,  Denmark, 1888 (1-0, 27). - Rick

7.O-O d6 8.dxe5 

In this complicated line, White would have done better to capture the Bishop. - Rick

8...Qxe4 9.Nd2 Qd5 10.exd6 Bxd6


11.c4 Qd3 12.Qh5+ Qg6 13.Qh4 


This was ill considered, and led to the exchange of queens, which White was anxious to avoid. 

13...Qh6 14.Nf3 Qxh4 15.Nxh4 Nf6 16.Be3 b6 17.Nf3 h6 


It is difficult to see any compensation for the sacrificed piece, beyond the extra pawn. - Rick

18.Rac1 c5 19.Rfe1 Bb7 20.Nh4 Rad8 21.h3 Ng8


The beginning of a well devised and strong attack.

22.Rc3 Ne7 23.g3 Rhe8 24.Ra3 a5 25.Rb3 Bc7 26.Bxc5


Well planned, but premature, not having well considered Black's next move, which was the closing tour of the Kt in his ferocious perigrinations. Mr. Gingras is, undoubtedly, one of the strongest players in the state, and this game demonstrates his superior ability.

26...Nf5 27.Be3 Nd4 28.Rd3 Ne2+ 29.Kh2 Rxd3 30.Rxe2 Rd1 

31.f3 Rd3 32.Ng2 Bxf3 White resigned


I would have enjoyed seeing a rematch, where the winner of this game played White - with the Jerome Gambit. - Rick

Jerome Gambit: Startling Discovery


Dan Watson continues to do research on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and its inventor (see "Alonzo Wheeler Jerome Update"). He has recently shared some historical news stories, and an over-the-board game that I never seen before.

Most interesting, he has a correction to the year that a particular Jerome Gambit game was played - instead of about 25 years after Jerome's analysis in the Dubuque Chess Journal, it appeared about a decade before Alonzo Wheeler Jerome debuted his opening.

His source is The New York Clipper,  vol. 38 no. 27, Saturday September 13, 1890, which I quote, below, while adding diagrams. My notes are in blue - Rick.


Tonetti - Ruggieri

Rome, 1863

Up until I received this article, I had dated this game 1890. - Rick

The following dashing skirmish is historically interesting as a commentary on the propensity to multiply the nomenclature of the gambits. It was played at Rome in September 1863 - Nuova Riviste.

The Chess columnist in the Clipper is referring to Nuovoa rivista degli scacchi, Genn. - Febb. - Marzo, 1890, Anno XVI, p.34. - Rick

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

But we never heard that the brilliant Italian master ever demanded that it be dubbed the "Tonetti gambit;" in fact, we suppose that the variation has been known ever since there was a "Giuoco Piano".

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 


7.Qf5+ Kd6 8.d4 Bxd4


To this point the game may be found in Miller's Cook's Synopsis. White's 9.. [sic] seems a strong and important variation.

In 1884, J.W. Miller, of Cincinnati, published Cook's Synopsis of Chess Openings A Tabular Analysis by William Cook, With American Inventions in the Openings and Fresh Analysis since 1882 - Rick

9.Bg5 Nf6 10.c3 Bc5 11.b4 Bb6 12.O-O Re8 


13.Rd1+ Kc6 14.b5+ Kxb5 15.Na3+ Ka5 16.Nc4+ Kb5 17.Nxe5 d6

18.Rab1+ Ka6 19.Qf3 c6 20.Qd3+ Ka5 21.Nc4+ Ka6 22.Nxb6+ Ka5 23.c4 Black resigned


Dan also sent an English translation of Italian commentary on the game

This game played in Rome in September 1863 proves how the originate attack, of modern origin, put into vogue in 1874 by A. W. Jerome, an American player, practiced much earlier in the Roman academy. Unfortunately, Italians often leave the glory and the name of their discoveries to foreigners.

This game is the earliest Jerome Gambit that I have in The Database. I have focused my research on 1874 (the date of Alonzo Wheeler Jerome's first published article on the gambit) and later. Clearly, I need to return to the Morphy era to search some more.

By the way, in 1877 Nuovoa rivista degli scacchi published a game by Alonzo Jerome playing his gambit, as well as Sorensen's analysis of the Jerome Gambit, and in both cases, did not mention the Tonetti - Ruggieri game. 

Any Reader who has more information on this game, Tonetti - Ruggieri, Rome, 1863, is encouraged to share.
