Jerome Gambit: Success At Last (Sort of)

Image result for free clip art tiny award
For some players, a draw is equivalent to losing a half point. To others, it is the same as winning a half point. In the following game, Bill was probably slightly disappointed, but his opponent had every reason to be glad - unless, of course, you think that drawing against a "refuted" opening is underperforming.

Wall, Bill - NN
Florida, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Kf8

Black is either happy with accepting only one sacrificed piece, or he is trying to throw White off of his game, by playing something "different". This latter strategy needs to be examined, as the main lines of the offbeat Jerome Gambit are often stronger for Black than the backroads.

The Database has 269 games with 5...Kf8; White scores 55%. More importantly, before the current game Bill was 15-0 against the move.



6.O-O

Bill has also played 6.Nxc6 in Wall,B - WMXW, FICS, 2012 (1-0, 31), and Wall,B - Guest709079, PlayChess.com, 2017 (1-0, 30).

He has tried the interesting 6.d4 in Wall,B - Tim93612, Chess.com, 2010 (1-0, 36), Wall, B. - Guest757851, PlayChess.com, 2014, (1-0, 42), and Wall,B - Guest6399506, PlayChess.com, 2015 (1-0, 24).

6...Nf6

Or 6...Nxe5 Wall,B - Mazanbaku, lichess.org, 2017, (1-0, 15); Wall,B - Guest1442, chesstempo.com, 2017, (1-0, 21); billwall - DeDrijver, Chess.com, 2012, (1-0, 20); Wall,B - Guest423598, PlayChess.com, 2017, (1-0, 19); and Wall,B - Guest5244307, PlayChess.com, 2019 (1-0, 16).

Or 6...Qf6 as in Wall,B - NN, lichess.org, 2016, (1-0, 13); Wall,B - Computer-level 6, chess.com 2017 (by transposition), (1-0, 47);  and Wall,B -Guest4658155, PlayChess.com, 2019, (1-0, 29).

Or 6... d6 as in Wall,B - Anonymous, lichess, 2016, (1-0, 26) and Wall,B - Guest399227, PlayChess.com, 2016,(1-0, 17).

7.Nd3 

This is a novelty, according to The Database.

7...Bb6 8.e5 Ne8 

It is not immediately clear, but 8...Ng8 was stronger. The text move gives White chances that he is not particularly interested in.

9.Qf3+ Kg8 10.Nc3 

Bill refrains from repeated checks that would leade to a draw, i.e. 10.Qd5+ Kf8 11.Qf3+ Kg8 12.Qd5+, etc. Black could respond, of course, by interposing the Knight - 11...Nf6 - but after 12.exf6 Qxf6 13.Qxf6+ gxf6 he would simply be a pawn down, with no compensation.

10...a6 

This move gave me a chuckle. "Objectively", it is an error, as it allows White to pursue the draw, mentioned above, when clearly Black is still better. On the other hand, perhaps Black was okay with a draw, or sensed that his opponent would not be interested in splitting the point so early in the game.

11.Qd5+ Kf8

Just checking.

12.Na4 

Avoiding the draw.


12...Ba7

See the earlier comments. He could have taken the draw off of the table with 12...Qe7

13.b3

ibid.

13...d6 

op. cit.

14.Ba3 Qe7

There you have it: no draw. (For now.)

White is happy to continue his focus on the enemy King.

Black is happy to continue to do "a whole lot of nothing". Note the impact of his dark square Bishop.

15.exd6 cxd6 16.Rae1 Nf6 17.Qf3 Qd8 18.Nc3 h6


19.Nf4

An interesting, if complicated, alternative was 19.Ne4!? Kg8 20.Nxd6, although both 20...Bg4 and 20...Nd4 would keep the game in flux.

Instead, Bill goes with the concrete threat, and his opponent misses the idea that giving up the exchange might well be an effective sacrifice.  

19...Kg8 20.Ng6 Rh7 

Saving the Rook by burying it. There was something to be said for 20...Kh7!? 21.Nxh8 Kxh8, when White would have a Rook and two pawns for a couple of pieces - and Black might still have an edge.

21.Nd5

A move with poison. Of course, not now 21...Nxd5, as 22.Qxd5+ Be6 23.Qxd6 checkmate. Ouch. In the meantime, e7 seems to beckon to the Knights.

21...Bc5 

22.Bxc5 

Could be time pressure, otherwise Bill might have settled for simply stoking his attack with 22.Bb2. Stockfish 10 recommends 22.b4, which seems to over-complicate things. Instead, the attack seems to lag. 

22...dxc5 23.c4 Qd6 24.Qd3 Nd4 



Black's Rooks are still parked in their respective garages, but the advantage in material threatens to become a factor.

25.Nxf6+ 

Another way was 25.Nge7+ Kh8 26.Ng6+ Kg8 27.Nge7+, etc.

25...gxf6 26.Re8+ Kf7 27.Re7+ Kg8 28.Re8+ Kf7 29.Re7+ Kg8 Draw

Happy New Year! (A Hysterical/Historical Jerome Gambit, Part 2)



                               [Continued from Christmas.] 


So far, the close look at my recent Jerome Gambit game has progressed a half-dozen moves. See "Merry Christmas! A Hysterical/Historical Jerome Gambit, Part 1".

Again, I have historical information from my never-published article submitted to Stefan Bucker for his magazine Kaissiber (and revised, and revised, and revised, and revised, and reassessed).

This position was reached in his first article with analysis of the Jerome Gambit (Dubuque Chess Journal 4/1874) by Alonzo Wheeler Jerome

As early as July 1874 it was clear that Alonzo Wheeler Jerome had no illusions about his gambit, as the Dubuque Chess Journal noted

It should be understood that Mr. Jerome claims in this New Opening "only a pleasant variation of the Giuoco Piano, which may win or lose according to the skill of the players, but which is capable of affording many new positions and opportunities for heavy blows unexpectedly.
This modesty did not prevent Jerome from debating for months with William Hallock, who produced the American Chess Journal in the years following the demise of the Dubuque Chess Journal. While testing his invention in over-the-board and correspondence play, Jerome claimed
…that the opening has a “reasonable chance of winning,” which is sufficient to constitute a “sound opening.” It is not required that an Opening shall be sure to win. There is no such opening contained in chess; at least none that I know of.
In the exchanges of games and analysis that appeared in the American Chess Journal in 1876 and 1877, Hallock progressed from referring to “Jerome’s Double Opening” to “Jerome’s Gambit” to “Jerome’s Absurdity.”
                       
This light-hearted approach found full form in the May 1877 issue of the Danish chess magazine Nordisk Skaktidende, where Lieutenant Sorensen, analyzed the Jerome Gambit in his “Chess Theory for Beginners” column:
With this answering move of the Bishop [1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5] we have the fundamental position for that good old game which the Italians, hundreds of years ago, when they were masters of the Chessboard, called "Giuoco Piano," even game, but the later age, for generality of explanation, the "Italian game." On this basis the usual continuation is 4.c3, whereby the QP at the next move threatens to advance, and the White middle Pawns to occupy the centre. In the next articles we will make mention of that regular fight for the maintenance or destruction of the center, which is the essential point of the Italian game; in this, on the contrary, we will occupy ourselves with a Bashi-Bazouk attack, over which the learned Italians would have crossed themselves had they known it came under the idea of piano, but which is in reality of very recent date - 1874, and takes it origin from an American, A.W. Jerome. It consists in the sacrifice of a piece by 4.Bxf7+. Naturally we immediately remark that it is unsound, and that Black must obtain the advantage; but the attack is pretty sharp, and Black must take exact care, if he does not wish to go quickly to the dogs. A little analysis of it will, therefore, be highly instructive, not to say necessary, for less practiced players, and will be in its right place in our Theory, especially since it is not found in any handbook. The Americans call the game "Jerome's double opening," an allusion, probably, to the fresh sacrifice of a piece which follows at the next move, but we shall prefer to use the short and sufficiently clear designation, Jerome Gambit.
The August 1877 issue of the British Chess Player’s Chronicle and the December 1877 issue of the Italian Nuova Rivista Degli Scacci, reprinted Sorensen’s article (in English and Italian, respectively), introducing the Jerome Gambit to an even wider audience. Almost every Jerome Gambit analyst since has leaned heavily on Sorensen.

Interest in the Jerome Gambit did not remain just among beginning chess players. A couple of years later, Andres Clemente Vazquez included three wins with the Gambit, from his 1876 match against     Carrington, in his Algunas Partidas de Ajedrez Jugadas in Mexico por Andres Clemente Vazquez.

G. H. D. Gossip’s 1879 book, Theory of the Chess Openings, included an analysis of the Jerome Gambit, “substantially the same” as that which appeared in the Chess Player’s Chronicle, as the latter noted in a review of the work. At about the same time, the American daily newspaper, the Cincinnati Commercial Gazette, in its chess column, struck the right tone in its review of Theory, noting gleefully
...the Jerome Gambit, which high-toned players sometimes affect to despise because it is radically unsound, finds a place, and to this it is certainly entitled.
The next year, in 1880, when the 6th edition of the illustrious Handbuch des Schachspiels was published, the Commercial Gazette’s chess columnist was again ready to “complain” about the state of affairs


…that the "Jerome Gambit" should be utterly (even if
deservedly) ignored.

The Cincinnati connection is an important one in the story of the development of the Jerome Gambit. In the 1870 and 1880s, the chess column of the Commercial Gazette, conducted by J. W. Miller, was considered to be one of the best in the United States. It occasionally ran opening analysis presented by S. A. Charles, a member of the local chess club. By January 1881, Charles had switched to sending his analyses to the Pittsburgh Telegraph (later, the Chronicle-Telegraph).

In October 1881, the Jerome Gambit broke onto the international scene again, in Brentano's Chess Monthly, (edited by H.C. Allen & J.N. Babson), with a letter and analysis from S. A. Charles.


The November 2, 1881 chess column in the Pittsburgh Telegraph ran Charles’ corrected and slightly updated version of his analysis from Brentano's Chess Monthly.


The year 1882 brought yet more attention, from respectable sources, to the Jerome Gambit. William Cook, with the assistance of E. Freeborough and C. E. Ranken, brought out the third edition of his Modern Chess Openings-style Cook's Synopsis of the Chess Openings A Tabulated Analysis. 



7.0-0


Like in the "annoying defense" against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5+ 6.Qh5+ Ke6 7.f4 d6 8.fxe5 dxe5, etc.), Black has returned a piece to achieve a static position that limits White's attacking chances.

Here, though, White has the long-term plan of developing and deliberately advancing his "Jerome pawns". If Black is watchful during this process, he can probably return a second piece for two pawns and sue for peace.

Also played (often transposing) has been 7.d3, as in perrypawnpusher - Jore, blitz, FICS, 2011 (0-1, 16); perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 13); perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 29); perrypawnpusher - Lark, blitz, FICS,  2011 (1-0, 12); perrypawnpusher - pitrisko, blitz, FICS, 2011 (0-1, 30); and Wall,B - WMXW, FICS, 2012 (1-0, 31).


7.Nc3 (followed by 8.d3 and 9.0-0 ) was seen in perrypawnpusher - Ykcir, FICS, 14 0 blitz, 2009 (½-½, 11).


7.c3 was seen in Vazquez,A - Carrington,Wm, Mexico, 2nd match 1876 (1-0, 43).


7...Be6 


7...Nf6 was popular in the early games of this line, as in Jerome,A - Brownson,O, Iowa 1875 (½-½, 29); Norton,D - Hallock,A, correspondence, 1877 (0-1,18), Lowe,E - Parker,J, correspondence, 1879,  (0-1, 25);  and Lowe,E - Parker,J, correspondence, 1879 (1-0, 37).


Subsequent analysis has generally followed Jerome - Brownson, Iowa, 1875, with 7.O-O Nf6 8.Qf3 (Sorensen said 8.e5 would be met by 8…Bg4 9.Qe1 Kf7! which was how Norton – Hallock had continued ) Qd4 9.d3 Bg4 10.Qg3. At this point, Brownson played 10…Bb6. Jerome responded with 11.e5, and drew the game, with help from his opponent, in 29 moves. Brownson, in the Dubuque Chess Journal (3/1875), suggested 11.Kh1 and 12.f4 as an improvement for White.


Sorensen, Nordisk Skaktidende, (5/1877) gave the alternative line 10…Bd6, attacking White’s Queen, and followed this up with 11.Bf4 g5 12.Bxd6+ cd 13.h3 Be6 14.Qxg5 Rg8 15.Qh6+ Ke7 16.Nc3 Rg6 17.Qh4 Rag8 with a better game for Black. However, Charles later in the Pittsburg Telegraph (4/27/81) offered 11.c3 as an improvement, suggested to him by Jerome, which they believed reversed the valuation of the line.


As an historical aside, later sources, relying on - read: copying - Sorensen’s analysis, miss 11.c3; those that follow - read: copy - Charles’ work, based on his Brentano article or on the American Supplement, include it.


8.d3 


Better than my goofball 8.Qf3+ from perrypawnpusher - CorH, blitz, FICS, 2009 (0-1, 74). 


8...Qf6 9.Nc3 Ne7 10.Be3 Bd6
