Jerome Gambit: History in Play



My first win with the Jerome Gambit, in the second round of the "Italian Game Classic" tournament at Chess.com, was a bit of a journey through the opening's history.

An unfortunate slip by my opponent allowed me a tactical shot that brought the game to an early conclusion.

perrypawnpusher - PDX84
Italian Game Classic, Chess.com, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 




Black courageously thinks of holding onto both sacrificed pieces. The compter chess analysis at Chess.com, after the game, identified the move as "best".

7.Qf5+

Alonzo Wheeler Jerome first suggested this move in the April 4, 1874 issue of the Dubuque Chess Journal. He also played 7.f4 and 7.O-O in correspondence games against S.A. Charles, and suggested 7.b4 "for analysis"; this was covered in the October, 1881 issue of Brentano's Chess Monthly.

A check of The Database shows 507 games with 7.Qf5+, with White scoring 48%, as opposed to 517 games with 7.f4, with White scoring 61%. There are no games with 7.b4.

7...Kd6 8.f4 Qf6 9.fxe5+ Qxe5 10.Qf3 



Not 10.Qxe5+ this time. That move has given me mixed results, and a loss most recently: perrypawnpusher - djdave28, Italian Game Tournament, Chess.com, 2014, (1-0, 22); perrypawnpusher - djdave28, Italian Game Tournament, Chess.com 2015, (1-0, 32); and perrypawnpusher - Altotemmi, Giuoco Piano Tournament, Chess.com, 2016, (0-1, 51). 

The Queen exchange is at least as old as Jerome, A - Jaeger, D, correspondence, 1878 (0-1, 68).

10...Nf6 

This move makes a lot of sense.

Jerome faced 10...Ne7 in a correspondence game against Jaeger in 1878 (0-1, 68).

 Lowe,E - Cudmore,D, correspondence, 1881, continued 10...b5 (½-½, 48).

Keeble,J - Cubitt,J, Norwich 1886, continued 10...c6 (1-0, 17).

11.d3 Ke7 

Black dodges the crudest of threats - 12.Bf4, pinning his Queen to his King. The idea is at least as old as Vazquez - Giraudy, Mexico, 1876 (remove White's Queen Rook) 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.d4 Bxd4 9.c3 Bb6 10.f4 Qf6 11.fxe5+ Qxe5 12.Bf4 Qxf4 13.Qxf4+ Ke7 14.Rf1 Nh6 15.Qe5+ Kd8 16.Qxg7 Re8 17.Qg5+ Re7 18.Rf8 checkmate. Still, I've scored points from this "Optical Illusion" variation of the Jerome Gambit - see "Optical Illusion (1)", "Optical Illusion (2)" and "Disdainful Defender Defense".

Instead, 11...Kc6 was seen in Jerome, A - Colburn, correspondence 1879 (0-1, 34) and Jerome, A - Charles, S.A., correspondence, 1881 (unfinished).

12.Nc3 Bb4 

Pinning the White Knight to keep it off of d5.

Instead:

12...g5 was seen in Jerome, A - Shinkman, W, Iowa, 1874 (0-1, 21);

12...d6 was seen in Jerome, A - Brownson, O, Iowa, 1875 (1-0, 43);

12...c6 was seen in Jerome, A - Amateur, off hand game, 1876 (1-0, 20); and

12...d5 was seen in Jerome, A - Pane, M, correspondence, 1878 (1-0, 41).

13.Bd2

I was amused to see that I had played 13.O-O here, years ago, in perrypawnpusher - PREMK, blitz, FICS, 2005. The idea was that 13...Bxc3 14.bxc3 Qxc3 15.Qg3!? would give White good play for the sacrificed pawn.

13...Rf8 14.O-O d6 

Instead, in the post mortem, Komodo 10 recommended the brutal 14...Bd6, with the idea of forcing exchanges to eliminate White's attacking chances and highlight Black's piece-for-a-pawn advantage, e.g. 15.g3 c6 16.Bf4 Bc5+ 17.Kg2 Qh5 18.Na4 Qxf3+ 19.Rxf3 d6 20.Nxc5 dxc5 21.Raf1 Bg4 22.R3f2 Be6 

15.Nd5+ Black resigned

White will recover his sacrificed piece. He will be a pawn up, with better development and King safety. Black decided not to play on.

Say, what...?


While playing against an opponent who has a sense of what is going on in the Jerome Gambit is one thing (see, for example, "La la la la la..."), playing against an opponent who seems to be bamboozled can be quite another, as axykk demonstrates...


axykk - bromby
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


When Black makes this move it usually means that either he is new to the Jerome Gambit, and wants to hang on to the second piece, or that he has studied the Jerome Gambit and this is the defensive system that he is most comfortable with.

The Database indicates that bromby faced and defeated a "modern" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3) in 2006; and drew and won against Petasluk in 2009 in a couple of 5.Nxe5+ Nxe5 6.Qh5+ Ng6 games. So: not necessarily "new" to the Jerome Gambit, but is he prepared ?

7.Qf5+ Kd6 8.f4 Qf6


A solid defense, as we know from analysis dating back to Alonzo Wheeler Jerome and the April 1874 issue of the Dubuque Chess Journal. Over the years, Shinkman, Jaeger, Colburn and Charles beat the opening's "inventor" with it.

9.fxe5+ Qxe5 10.Qxe5+

This is a relatively new idea, as opposed to retreating the Queen to f3. The Database has games with this move by Louis Morin in each of 2001, 2002, and 2003, all wins.

I don't think that bromby was quite prepared for it.

10...Kxe5 11.b4

" 'Freedom' 's just another word for 'nothing left to lose' " as the song goes. Axykk can play freely with the White pieces, as he's already had a "lost" game since move 4. What is the worst thing that can happen now?

11...Bb6

Suspicious of White's motives, Black retreats.

It seems silly to point out that 11...Bd4 12.c3 Bb6 13.d4+ Kxe4 was better – not everyone wants to know what happens after 14.Nd2+ Kf5 15.0-0+, especially against a higher-rated player at blitz speed.

12.Bb2+ Kxe4

Befuddled. At a distance we can recommend the same notion as above, with 12...Bd4 13.c3 Bb6 14.d4+ and even after 14...Kxe4 Black will be better.

13.Bxg7

Black resigned

It might have been worth hanging around to try (wait for it...) 13...Bd4, as White would have to find 14.Nc3+ to keep his edge, i.e. 14...Bxc3 (nothing else comes close to working) 15.dxc3 Ne7 16.Bxh8 when White would be a solid exchange ahead, and his Kingside pawn majority would spell future trouble for Black.

Jerome Gambit Nomenclature

Jerome Gambit Gemeinde member Bill Wall has been working on an orderly way of naming the various Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) variations.

Sometimes a move or line is given a generic label (e.g. "5.a3 Variation"), but when possible it is given the name of the person known to have played it first.

(This is based upon my 9 years of research into the Jerome Gambit. Of course, further discoveries may change things.)

There are a few exceptions (e.g. 5...Kf8, the "Sorensen Variation"), where the name given refers to someone who did significant analysis of the line, or greatly popularized it (e.g. 7...d6, the "Blackburne Variation").
