The Classics I (a first look)



In recent posts I have suggested that those who play, and those who face, the Jerome Gambit, would benefit from becoming familiar with "the classics" of that line.

That got me thinking: What would those classics be?


I have come up with a preliminary sketch. I think all of the games (except one) have appeared on this blog.


0. Jerome - Dougherty


Alonzo Wheeler Jerome has written that his first Jerome Gambit was played against George Dougherty. Although I have not yet been able to find the game, it most likely occurred before the April, 1874 issue of the Dubuque Chess Journal, where the first analysis of the Jerome Gambit was presented. Of Dougherty I know little, but the following notice occurred in the Dubuque Chess Journal, May 1875

Our Portfolio

Chess Challenge
George J. Dougherty, of Mineola, Queen's County, New York, hereby respectfully invites John G. Belden, Esq., of Hartford, Conn., to play him two games of chess by Postal Card, at his convenience, Mr. Belden taking the attack in one game and Mr. Dougherty in the other; the object being to test the soundness of Jerome's Double Opening, published in the April No. (50) of this Chess Journal.


1. Jerome - Shinkman, Iowa, 1874


The first published Jerome Gambit played by Jerome that I have been able to uncover (in the July issue of the Dubuque Chess Journal) was a loss by White.


2. Jerome - Whistler, correspondence, 1876


Largely lost to the chess-playing public, the correspondence match between Jerome and Lt. G.N. Whistler (one game survives) tested the latter's defense to the Jerome Gambit. Alas, a crushing defeat for White - who rarely, if ever, seemed to remember to mention the line thereafter.


3. Vazquez - Giraudy, exhibition, Mexico, 1876


In perhaps the most outrageous Jerome Gambit played, the Mexican champion, giving Rook odds, checkmated his opponent in 18 moves.


4. Vazquez - Carrington, 2nd Match, Mexico, 1876

This is actually a "composite" listing, as the Mexican champion played the Jerome Gambit three times (games 1, 5 and 9) in his match with William Carrington, winning them all.


5.  D'Aumiller - A. P., Livorno, 1878



This miniature played in Livorno, Italy - lasting 19 moves, at which point White announced a mate in 4 - was published in the May 1878 issue of Nuova Rivista degli Scacchi, showing that the Jerome Gambit had already hurdled the ocean.

The Wisdom of The Database (Part 1)


It's time again (see the earlier "Opening Report" parts 1, 2, and 3) to use ChessBase's Opening Report function to take a look at the games in The Database. 

The Report gathers what lines are being played, and what lines are being used by the top players in the database. It gives a good "real life" view of the play of the Jerome Gambit, even if it does not always identify the objectively best move or line. (That would require a process called backsolving, which is not available in my ChessBase8.)


The Opening Report again also highlights a number of games from an interesting 2008 30-game human vs computers match (starting with "Jerome Gambit: Drilling Down (1)"

This post starts an extended series (which may be interrupted from time-to-time for news, games or analysis) wherein the intrepid "RevvedUp" (a good chess player) and his trusted companions Hiarcs 8, Shredder 8, Yace Paderborn, Crafty 19.19 and Fritz 8 explore the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) by taking turns playing the White and Black pieces. 

The human moves first, and takes notice of the defense the computer plays. In the next game, where he moves second, the human plays that defense against a new computer – and sees how it attacks. In the third game, the human plays the recent attack against his new computer foe. Collectively, the players drill deeper and deeper into the Jerome Gambit.

Opening Report (Part 1)


I decided to have ChessBase8 give me an Opening Report on the Jerome Gambit, based on The Database. I got a whole lot of information, and I was only dealing with the first few moves...

Maybe I'll ask it, later, to look deeper.

A Day in the Life of the Jerome Gambit



Some Jerome Gambit games are instructive, from beginning to end, showing what a player must face and accomplish in order to be successful.

Wall,B - Guest903719 
playchess.com, 2013

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


4...Kxf7 5.Nxe5+ Nxe5 6.d4 



6...Bxd4 7.Qxd4 d6 8.0-0 Nf6 9.f3 



This is an interesting Theoretical Novelty. Previous play has centered around White working quickly for e5 or f5, while Black counters with pressure from his Rook along the e- or f-file.

9.f4 is a continuation going back to Jerome,A - Shinkman,W, Iowa, 1876 (½-½, 42).

9...Rf8 10.Nc3 Kg8 11.b3 Bd7 12.Bb2 Qe8 13.Nd5 Nxd5 14.Qxd5+ Qf7 

White is planning another episode of "You can't play like that!"

15.Qxb7 Bc6 16.Qa6 

Threatening 17.Bxe5. 

16...Qd7 17.Rfd1 

Threatening 18.Bxe5 

17...Bb5 18.Qb7 Ng6 

White has grabbed a second pawn to compensate for his sacrificed piece, he has a strong Bishop at b2, and there are weaknesses on the light squares in Black's position.

A computer would still like Black, but this is a human vs human contest.

19.e5 Nf4?! 

Bill recommends, instead, 19...Bc6 20.Qb4 d5.

20.exd6 cxd6 21.Qxd7 Bxd7 22.Rxd6 



All Jerome Gambit players should become familiar with playing this kind of position for White. With three pawns for a piece, White has gained material equality, but his "Jerome pawns" give him "means, motive and opportunity" to try for more.

22...Bf5 23.Re1 Bxc2 24.Re7 Rf7 25.Rxf7 Kxf7 26.Rd7+ Ke6 27.Rd2 Rc8 28.Bxg7 Bg6 



29.g3 Nd3 30.Kg2 Rc1 31.g4 Re1 32.Bd4 a6 33.h4 Kd5 34.Bf2 Ra1? 

Black misses the opportunity to exchange down to a drawn Bishops-of-opposite-colors endgame with 34...Re2 35.Rxe2 Nf4+ 36.Kf1 Bd3 37.Ke1 Bxe2 38.Be3 Bxf3 39.Bxf4 Bxg4.

This blog has presented many examples of the resources and pitfalls of such endings.

35.h5 Be4 36.fxe4+ Kxe4 37.Kg3 Nc1 



This may have been what Black had in mind when he gave up his Bishop for a pawn (the White Queenside pawns fall), but White has seen further.

38.Rd4+ Ke5 39.Rd7 Rxa2 40.Rxh7 Nxb3 41.Re7+ Kf6 



42.h6! Kxe7 43.h7 Kf6 44.h8Q+ Ke7 45.Qe5+ Kd7 46.Qd5+ Ke7 47.Qxb3 Black resigned

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.

The Norton - Hallock Game (Part 2)

After the correspondence game Norton - Hallock – a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) – appeared in the February issue of the American Chess Journal – see "The Norton - Hallock Game (Part 1)" – the Gambit's creator was quick to respond.

Jerome's letter to editor William Hallock, below, is from the February 1877 American Chess Journal.
The Jerome Gambit
A.W. Jerome Defends His Opening as tested in game 79.
Paxton, ILL March 7, 1877
Editor, American Chess Journal,
Your card received this morning, and I thank you for your kind offer of room in The Journal for an article on the "Jerome Double Opening," alias "Jerome's Absurdity."

I have neither the time nor the ability to prepare such an article, for it would require analyses without number almost, and I have satisfied myself that my head is not level enough for such work. Of this I need not be very much ashamed when even Mr. Carpenter oversights occasionally.

Besides I believe "the proof of the pudding" is in the eating therov and not in "chewing the string." Norton, Shinkman and Kinnier have beaten me in "eating the pudding" more in consequence of dexterity in handling the "chess sticks" than in any superiority of their pudding over mine. In most of their tests they have made dough of my pastry, by reason of the lack of one essential ingredient in my part, viz foresight.

But in game 7 with Norton, and in the variation of that game from 22nd move, I think my side has been played as well as it could be, and the outcome will probably justify your opinion expressed in the November Journal, that "against careful, steady play the opening cannot win." A master might make a draw from the present position in each game. I probably cannot do that against Norton.
To those who like a lively, exciting game, I would say, try an "absurdity." If the first player gets no fun out of it, the second will.
But all joking aside, I maintain that the loss of the King's and Kings' Bishop's pawns, and privilege of castling comes very close in value to the one piece which has been sacrificed, and the second player must be on the alert or he will be quickly defeated.
Your game with Mr. Norton would seem to show the reverse to be truth but Norton's first mistake was in playing 5.e5 instead of 5.Qf3 as in game 472, Dubuque Chess Journal where the defense was the same. That game was drawn, but should have been won. Note (a) to your game with Norton says 5...Kf8 "seems equally good with 5...Nxe5" which is a mistake in fact and theory. 5...Nxe5 if properly followed up wins White's KBP, wheras 5...Kf8 leaves White's pawns intact while Black has lost two strong pawns and doubled another. This defense was adopted by G.J. Dougherty of Mineola, NY, a strong amateur, against whom I first played the opening, and I think he will agree that 5...Kf8 is not a good defense. He generally played 6.bc and that was the play of Mr. J. C. Young of Danville, KY, who subsequently abandoned the game. Why, I do not know, as it was not necessarily lost to either of us. It is a question with which Pawn it is best to take.
The move suggested in note (b) 6.Qh5, is not my idea, but belongs to Mr. Norton himself, and I have to acknowledge that I thought it unsound when he suggested it to me, during the process of the game, because 6...Qf6 gets up a counter attack at once; but 7.Ng4 compels Black to "crawfish" and permits White to castle with a good game. However if Black play 7...Qe7 it makes White 's game uncomfortable. But White may play 7.Nxd7+ Bxd7 8.Qxc5+ with 3 Pawns for his Knight which the books hold to be an equivalent. And I would not hesitate to exchange Queens if offered. Norton thinks 6...Qe7 best; I think 6...Nxe5 best; if 7.Qxe5 Qe7
Ending notes (c) and (d) at the first glance, seems as safe as endorsing U.S. Treasury notes, but closer examination will show that 8...Bg4 loses Bishop as I think I will prove in the correction of note (f).Note (e) says "waste of time" not so; on the contrary is much better than 10.c3, for it 10...Re8 11.d4 Bxd4 12.cd Qxd4 and the KP is lost and Black has the best position. 10.Kh1 is good and safe. In note (f) there seems to me to be quite an oversight for if 13...Nxf2 14.Rxf2 and then if 14...Qf6 as suggested in the note, 15.d4 and it is Black's goose which is immediately done brown. Of course 13...Nxf2 is not best. Again I cannot see the easy win after 15...Rxe5 the attack is with White.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Kf8 6.Nxc6 [6.Qh5 Qf6 (6...Nxe5 7.Qxe5 Qe7) 7.Ng4 (7.Nxd7+ Bxd7 8.Qxc5+) 7...Qe7] 6...dxc6 7.0-0 Nf6 8.e5 Bg4 9.Qe1 Kf7 10.h3 Re8 11.Kh2 Rxe5! 12.Qxe5 Bd6 13.f4 Bxe5 14.fxe5 Be2 15.Rf2 Qd4 16.Rxe2 Re8 17.d3 Rxe5 18.c3 Qd5 White resigned

Never fear, good readers: tomorrow's post will apply Hallock's and Jerome's comments to the Norton - Hallock game in a much more understandable fashion.

(Un)Seen Before (sort of)

I was surprised to meet my opponent so soon after out last game (see "More Than Meets the Eye") but he didn't seem surprised to see my Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) again.

Although udofink had played a workable defense the first time, he switched up on me for our second game.

Unfortunately, he wandered into what I've casually referred to as an "optical illusion" – Bill Wall correctly does not include this "name" in his "Jerome Gambit Nomenclature" – that I've posted about before: see "Optical Illusion (I)" and "Optical Illusion (II)".

perrypawnpusher - udofink

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


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


The earlier perrypawnpusher  - udofink,  blitz FICS, 2010 continued 6...Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6 10.f4 Qh4+ 11.g3 Qg4 12.f5 Bf7 13.fxg6 Bxg6 14.d3 Kd7 15.0-0 Nf6 16.Nc3 c6 17.Qf4 Qe6 18.Bd2 Rhf8 19.Qg5 Rf7 20.Rae1 Raf8 21.e5 dxe5 22.Qxe5 Qh3 23.Bf4 Ne8 24.Qd4+ Kc8 25.Qxa7 Nd6 26.Qa8+ Kd7 27.Qa3 Nc8 28.Qc5 b6 29.Qd4+ Black resigned

7.Qf5+ Kd6 8.f4 Qf6


Racing the Queen to the Black King's defense, a wise idea mentioned as early as in Alonzo Wheeler Jerome's analysis ("New Chess Opening") in the April 1874 issue of the Dubuque Chess Journal. Black gives back a piece, but he adds to his development and threatens a Queen trade, which could break White's attack.

9.fxe5+ Qxe5 10.Qf3 Nf6 11.d3


From the Dubuque Chess Journal
compelling either K or Q to move as White threatens Bf4; or Black can play ...g5
Or at least you would think so.

Over the years Jerome faced 11...Ke7 (Amateur, Brownson, Kinnieu, Pane and Shinkman) and 11...Kc6 (Neufville and Charles).

This is the sixth time that I have reached this position, having seen 11...Ke7, 11...Bd4, 11...Re8, 11...Bb4+ and

11...Rf8 

12.Bf4 Black resigned


I can't explain Black's oversight, except to guess that it had to do with the time limit or that he was facing an opening that was so terrible that it didn't require all of his attention. 

Maybe he just didn't see my move.

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").
