Sac a pawn, or a piece, or a...

Why, oh why, do people play such a scary thing as the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)?

I play the opening myself, and I still ask that question. I found one kind of answer in a recent Chess Cafe book review by Steve Goldberg. He was writing about Timothy Taylor's new Pawn Sacrifice! (Everyman Chess, 2008)

Of course, in the Jerome Gambit White sacrifices more than a pawn, but often his two-pawns-for-a-piece material disadvantage is on the same level of loss.

Chapter 12, titled "Confusion," represents an interesting use of pawn sacrifices. Taylor explains, "Sometimes your opponent is just too smug. You look across the board, and there he is, wearing his Andy Warhol t-shirt, dreamily calm in the midst of his prepared variation/middlegame he’s crushed GMs with/grinding ending, and he just knows he’s going to win, and you’re just going to have to sit there and suffer, and he’s going to enjoy it."

Taylor’s advice is to "rip the gauzy comfort zone right off his smiling face! What do you do? You sacrifice a pawn for no other reason than to confuse your opponent! He says to himself, ‘That can’t be good!’ Then he thinks: ‘But why did he do it? – there must be some idea!’ Then, ‘I can refute this, but I have to leave my beloved comfort zone! Ohhhhh no!’"

Five games are presented in this chapter, and four of these "go from objectively lost, to confused, to winning." Fritz doesn’t approve any of these sacrifices, but Taylor states, "The confusion sacrifice is a very effective weapon against humans … The next time you have a bad position, or a position you simply don’t like, cheer yourself up! Sac a pawn just for confusion, then watch your opponent flounder! You will win many more games this way than if you drearily and unhappily defend."

More Jerome-izing

As we've seen in "King of Bxf7" there are many way's to Jerome-ize an opening. Here are a couple more, the first coming not too long after Alonzo Wheeler Jerome presented the world with his Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) analysis.

Jerome Gambit: Computer vs Computer


Wanting to test my conviction that the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) could be used as a way for a stronger player go give odds to a weaker player, I set up a 4-game blitz match (4 minutes, 2 second increment) on my computer between Fritz8 and Fritz5, with the stronger program playing White each game.

The result was initially quite surprising: Fritz8 / White / the Jerome Gambit won three games, and lost one.

A closer examination revealed, however, that Games 1, 3 and 4 – White's wins – were identical, with Fritz5 / Black resigning at move 29 each time. Fritz8 had varied at move 13 in the second game and had gone on to lose.

So, it was more like Fritz5 played it's "older brother" even in defending against the Jerome Gambit, winning one unique game and losing one unique game. On the other hand, Fritz8 bettered the 40% - 45% score we've seen White achieve in recent Jerome Gambit thematic tournaments.

Further research is certainly needed!

"Review of Mr. Gossip's Book" Theory of the Chess Openings
(1879)

...The Jerome Gambit

We do not well know why this opening (a branch of the "Giuoco") is styled a gambit, as it consists in White sacrificing a piece on the fourth move, and Staunton in his Handbook defines a gambit as a sacrifice of a Pawn.The Americans recognize the force of this by styling the opening "Jerome's double opening," although we don't quite see the meaning of this. How "double"? We think that the simple and natural definition of Jerome's Attack - as Cochrane's attack in the "Petroff" where a piece is also given up by White on his fourth move - would suffice.Like all presents of a piece early in the opening, the party so venturesome comes to early disaster. Mr. Gossip was right, therefore, in not devoting too much space to a debut which he could not establish as sound...

[Gossip replied next month, August 1879, but said nothing about the Jerome]

We are somewhat disappointed that the "Thorold Variation" of the "Allgaier Gambit" should be dismissed with only a casual note in the appendix, and that the "Jerome Gambit" should be utterly (even if deservedly) ignored.

"Chess and Checkers"
"The Jerome Gambit"

Chess Editor Commercial Gazette
I notice in your chess column of to-day a review (copied from The New Orleans Times Democrat) of some analyses published in the American Supplement to Cook's Synopsis including my own analysis of the Jerome Gambit...The principal portion of the analysis is based on a number of correspondence games played between Mr. Jerome and myself, with some few compilations from other sources, including the above-mentioned. The result led me to regard the sacrifice of the Bishop as unsound, but that Black may easily err in his defense and lose...

Very respectfully,
S. A. Charles

The "Jerome Gambit," 4.BxPch, involves an unsound sacrifice; but it is not an attack to be trifled with. The defense requires study, and is somewhat difficult.

Our readers will perhaps remember that about two years ago we published an analysis of the Jerome Gambit which was furnished by its author. The following is from the New Orleans Times-Democrat, in an extended review of the American Edition of Cook's Synopsis. The "brilliant but unsound" (why, may we ask, is this antithesis so common that one would almost infer it to be necessary?) Jerome Gambit, invented by Mr. Jerome, of Paxton, Ill., about a decade ago, constitutes the next of the Americana, and concerning the analysis given by Mr. S. A. Charles we can only venture to say that it seems to combine much careful original work with variations compiled from such investigations as have been published upon this hazardous attack...

Pittsburgh Chronicle-Telegraph

February 27, 1884

In Cincinnati we met a number of players in the Mercantile Library, the chess room of which... We also had the pleasure of contesting several games with Mr. Jerome, of Paxton, Ill. He is well known as the author of the so-called Jerome Gambit, in which white sacrifices the Bishop by taking KBP on the fourth move of the Giuoco Piano game. Neither the gambit nor its author proved strong in the contest.

The Jerome Gambit Gemeinde (modern)


I start the "modern" era of the Jerome Gambit Gemeinde somewhat arbitrarily, taking note of the contribution of L. Elliott Fletcher, whose quite enjoyable Gambits Accepted, a survey of opening sacrifices (1954) contains an interesting Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game. Alas, the players are listed as anonymous, and the location and date are not given.


Invented by an American named Jerome in the latter part of the nineteenth century much of the analysis given below was originated by another American, S. A. Charles, and subsequently revised by Freeborough and Ranken. The opening is frankly unsound but Black's task is by no means easy and he can quite likely go wrong...
Micah Fisher-Kirshner (see"A Few Words With... Micah Fisher-Kirshner") certainly deserves membership, for defending the honor of the Jerome Gambit against an early chess program, Knight Stalker (aka Fritz1) in a 1993 match.Certainly Master Jack Young ("Bozo" of "Bozo's Chess Emporium") should have his enthusiasm for the Jerome Gambit in his "Meet Jerome" article in Randspringer #6, 1990-1991 rewarded with membership.

Although FIDE Master Eric Schiller might shrug off the honor, he deserves a place in the Gemeinde for writing about the Jerome Gambit during a time when few even thought or knew about it, let alone analyzed it or shared their assessments. Unorthodox Chess Openings (1998, 2002), Gambit Chess Openings (2002), and Survive and Beat Annoying Chess Openings (2003) have new analysis, although the author's attitude was less tongue-in-cheek than thumb-in-eye
This is another cyberspace gambit. Virtually no attention was paid to this reckless move [4.Bxf7+] until its supporters started talking about it on the Internet. It can't be found in recent tournament games, and there is a good reason: It stinks. White whips up a brief attack, easily parried, and then spends a long time trying to justify the sacrifice. A popular gambit in cyberspace, but in the real world, it only succeeds in games where Black is a very weak player.

It is important to include Tim McGrew (see "A Few Words With... Tim McGrew") author of "The Gambit Cartel" series of articles at ChessCafe, and explorer of some of the vicissitudes of the Jerome Gambit.

The Gemeinde likewise has membership for Life Master Brian Wall, who has a 100% record with the Jerome Gambit (at least after one game) and who has presented devestating analysis of the Whistler Defense (see "Jerome Gambit Tournament: Chapter VIII") – one of the best refutations of the Jerome Gambit to date.

It's not every day (month, year, decade, century...) that an International Master mentions or makes a suggestion concerning the play of the Jerome Gambit, and because he has, IM Gary Lane (see "International Master Gary Lane") has a place in the Gemeinde; although this is not likely to be mentioned on the FIDE website.

There also are a number of players who deserve mention for their brave commitment to playing the Jerome Gambit, starting with Pete Banks ("blackburne"), whose game GM Lane analyzed in one of his "Opening Lanes" columns at ChessCafe.

Of note also are Louis Morin, whose name should have been mentioned here much earlier for his Jerome Gambit swash-buckling, and A.B. Hailey, who has produced his share of theoretical games.

Gary Gifford, current editor and publisher of the Unorthodox Openings Newsletter (and co-author of the brand new and exciting Winning with the Krazy Kat and Old Hippo) – see "But - Is this stuff playable??" – has been supportive of Jerome Gambit discoveries.

Finally, there are the many players who have ventured Jerome's Double Opening. It is not possible to mention all, but certainly those who have played in the five thematic Jerome Gambit tournaments mentioned on this blog should be welcomed into the Gemeinde: bobbob78, brain50, braken, breaker, calchess10, Capt.Mandrake, Carlos Azcarate, casker, dandoo, delboy138, drewbear, eddie43, Gary_Seven, gobo, hogmaster, HPotter, jelgava, jemasc, Kevin the fruitbat, koloman, mediax, mika76, panga74, Piratepaul, queen st, Rail2Rail, Sir Osis of the Liver, splott, Temmo, TJay2465, tonik, TWODOGS, vlad-tepes, willitfw and yorkypuddn.

The Jerome Gambit Gemeinde (early)

Followers of Emil J. Diemer and the Blackmar Diemer Gambit (1.d4 d5 2.e4 dxe4 3.Nc3 Nf6) composed a community they referred to as the Blackmar Diemer Gemeinde.

It only seems fitting to outline such a community for those associated with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

Among the early members would of course be Alonzo Wheeler Jerome (1834-1902), credited with inventing the gambit, exploring it in over-the-board and correspondence play, and discussing it in the pages of the Dubuque Chess Journal and American Chess Journal.

Orestes A. Brownson, editor of the Dubuque Chess Journal, deserves membership in the Gemeinde, as he was enthusiastic about the Jerome Gambit, and from 1874 to 1876 published games played by Jerome and others.

William Hallock, editor of the American Chess Journal, was skeptical about the merits of the Jerome Gambit, referring to it at one point as "Jerome's Absurdity," but he carried on a discussion of the opening with Alonzo Jerome in the pages of the ACJ during the years 1876 and 1877. He can be considered part of the "loyal opposition" in the Jerome Gambit Gemeinde, (a role Gerhard Gunderam often took in the Blackmar Diemer Gemeinde).

Andres Clemente Vazquez, Mexican Chess Champion, played the Jerome Gambit three times in his 1876 match against William Carrington, scoring 3-0. The second (1885) and third (1889) editions of his Analisis del juego de ajedrez contain analysis of the gambit.

Henry Charlick, of Australia, who experimented with 1.d4 e5, played the Jerome Gambit in his 1881 match with J. Mann; and earlier experimented in his 1877 game against Holloway with what might be called the "Evans Jerome Gambit": 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Bc5 6.Bxf7 (1-0, 76).

Lt. S. A. Sorensen, whose "Skaktheori for Segyndere" ("Chess Theory for Beginners") in the May 1877 Nordisk Skaktidende analyzed the Jerome Gambit, saw his work translated and published all around the world. His 1888 game against an anonymous player (the first example of 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4 Qh4 that I have found) shows that he played the Jerome as well.

S. A. Charles, a member of the Cincinnati (Ohio, USA) Chess Club, wrote opening analyses, first for the Cincinnati Commercial Gazette, then later for the Pittsburgh Telegraph. It is in the latter paper that in 1881 he presented his examination of the Jerome Gambit. That year he also played an incomplete Jerome Gambit correspondence match with Alonzo Jerome.

J.W. Miller
, also of the Cincinnati Chess Club, published in 1884 Cook's Synopsis of Chess Openings A Tabular Analysis by William Cook, With American Inventions in the Openings and Fresh Analysis since 1882. It included a reprint of Cook's Synopsis, 3rd edition (1882) which had been very popular and was already out of print. The Synopsis contained analysis of the Jerome Gambit which was based largely on Sorensen's article. The American supplement portion of the book contained Jerome Gambit analysis based largely on the work of S.A. Charles.

E. Freeborough and and C. E. Ranken included analysis of the Jerome Gambit in their Chess Openings Ancient and Modern (1st edition 1889, 2nd edition 1893, 3rd edition 1896, 4th edition 1910), a book that has been reprinted at least once in the modern era (Hippocrene Books, 1974) and which has been the introduction to the Jerome for a good number of players.


There are others who played or wrote about the Jerome Gambit in its early days, and I hope to welcome them into the Gemeinde in future posts.

The Evans Jerome Gambit

From the Adelaide Observer, May 12, 1877
"Chess"
H. Charlick
"Chess in Adelaide"

The following long and stubbornly-contested game was fought April 4, 1877, on the occasion of the visit to Adelaide, during the Easter holidays, of Mr. A. Holloway, of Williamstown, formerly of the Bristol Chess Club. The other game, between the same pair of players, won, at the Kt odds, by Mr. Holloway, was published a few weeks ago. The present partie was played on equal terms.
