Jerome Gambit: Refutation


A recent visit to the Chess Only site -"This site will improve your Chess. Learn chess openings, chess endgame, chess traps. See best chess games of top chess players."- put me in touch with a post on the "Jerome Gambit Trap".

Included is the Refutation to the Jerome Gambit.

Do yourselves a favor, take advantage of Chess Only's generosity, check out the refutation. If you don't you might fall into the same ignominity that Black did in Banks - Karmmark, 2007, a 10-move checkmate that the site leads off with.

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...

A Long Day's Journey Into Checkmate

Welton Vaz shows that if you can't win a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game quickly (see "Provoked!", "Moment of Truth" and "Another Miniature from Brazil") it's okay to once again win it slowly.

Ghandybh  - nosseir
Chess.com, 2010

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


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


6...Ke6 7.Qf5+ Kd6 8.d3


This is an unusual alternative to the more frequently played 8.f4. Clearly White avoids the complexities associated with that move – 8...Qh4+ 9.g3 Nf3+, for starters – while preparing to put pressure on the Knight at e5 with Bc1-f4. On the other hand, he battles along lines where White remains two pieces down. 

8...Nh6

Black, in turn, takes immediate aim at the White Queen.

Two alternatives have been seen: 8...Qf6 9.Be3 Bxe3 10.fxe3 Ke7 11.d4 Nc4 12.Qc5+ Nd6 13.e5 Qh4+ 14.g3 Qe4 15.exd6+ Ke6 16.Qe5+ Qxe5 17.dxe5 cxd6 18.exd6 Kxd6 19.Nc3 Nf6 20.Nb5+ Ke7 21.0-0-0 b6 22.Rd4 Bb7 23.Rhd1 Bc6 24.Nc7 Rac8 25.Na6 Rhe8 26.Nb4 Kf8 27.Kd2 Re4 28.Re1 Rxd4+ 29.exd4 Re8 30.Rg1 Bb5 31.b3 Ne4+ 32.Kc1 Nc3 33.Kb2 Ne2 34.c4 Bc6 35.Rd1 Be4 36.d5 Kg8 37.Rd2 Ng1 38.Na6 Nf3 39.Rf2 Ne5 40.Kc3 Ng4 41.Rd2 Rf8 42.Rd4 Rf3+ 43.Kb4 Nf6 44.a4 Bc2 45.Nc5 bxc5+ 46.Kxc5 Ne4+ 47.Rxe4 Bxe4 48.b4 Rf6 49.a5 Kf8 50.Kd4 Bc2 51.b5 Ke7 52.c5 d6 53.c6 Kd8 54.b6 axb6 55.axb6 Bb3 56.Ke4 g6 57.h4 Rf5 White resigned, dott - dj-travis, GameKnot.com, 2004;

and 8...Nf6 9.Bf4 Qe7 10.0-0 g6 11.Bxe5+ Qxe5 12.Qxe5+ Kxe5 13.c3 Be7 14.Nd2 d6 15.g3 Bh3 16.Rfe1 Rhf8 17.d4+ Ke6 18.e5 dxe5 19.Rxe5+ Kd7 20.Rae1 Rae8 21.f3 Bd6 22.Rxe8 Rxe8 23.Rxe8 Kxe8 24.g4 h5 25.Nc4 Bf4 26.Ne5 Be3+ 27.Kh1 g5 28.Nc4 hxg4 29.Nxe3 gxf3 30.Kg1 g4 31.Kf2 Ne4+ 32.Ke1 Kd7 33.c4 c6 34.d5 c5 35.Nf5 b6 36.Ng3 Nxg3 37.hxg3 Kd6 38.Kf2 a6 39.b3 b5 40.a3 bxc4 41.bxc4 Ke5 42.Ke3 Bf1 White resigned, Nestor250168 - karmmark, thematic, Chessworld.net 2008.

9.Bxh6 gxh6

Rybka's assessment is that things have already entered the Twilight Zone, suggesting instead: 9...Rf8 10.Bg5 Rxf5 11.Bxd8 Rxf2 with a clear advantage to Black.

10.Nc3


Here 10.f4 would have led to the recover of a piece as well. 

10...Rf8 11.Nb5+ Kc6 12.Qxe5 d6


Capturing the White Knight with the King would have only led to an exchange of pieces (12...Kxb5 13.a4+ followed by 14.Qxc5), so Black protects his Bishop first.

He had sharper play in 12...Bxf2+ 13.Ke2 d5 14.a4 Bg4+ 15.Kd2 Qg5+ 16.Qxg5 hxg5 17.exd5+ Kb6 but it can be difficult to think of "attack" when your King needs "defense."




analysis diagram







13.Nd4+

Rybka points out the sneaky alternative 13.Qd5+, as 13...Kxb5 leads to checkmate, while 13...Kb6 and 13...Kd7 allow 14.d4.

The position has become complicated for both players, a situation that favors the one more familiar and comfortable with this kind of play.

13...Bxd4 14.Qd5+ Kd7 15.Qxd4


15...Qf6 16.Qxf6 Rxf6 17.f3


Black has managed to remove the immediate danger to his King, and he has the standard small advantage of a piece for two pawns, but this kind of position is like one's own back yard to a Jerome Gambit player. 

17...b6 18.Rf1 Bb7 19.Kd2 Rg8 20.g3 Kc8


21.f4 Rf7 22.f5 Rg5 23.Rae1 Rh5


Black has underestimated or overlooked his opponent's reply.

24.h4 Rg7 25.Rf3


25...d5

This only unleashes the "Jerome pawns".  

26.f6 Rf7 27.e5 d4 28.e6 Rf8 29.e7 Rh8


30.Rf4

Finally, Black catches a small break. White does not really need to worry about saving his Rook: after 30.f7 Bxf3 he can play 31.f8/Q+ Kb7 32.Qxf3+ Ka6 33.Qxh5 and be a Queen ahead, with another pawn ready to promote!

 30...Bd5 31.f7 Bxf7 32.Rxf7 Re8


Perhaps Black even chuckled here, and reminded himself of the old saying All Rook and pawn endings are drawn.

33.Re4 c5 34.Rf8 Kd7 35.Rf7


At this point, this Rook and pawn ending does look drawn.

But looks can be deceiving.

35...a5 36.a4 b5 37.axb5 Rd5 38.Rxh7 Rd6


White's pawns are beginning to look like ants at a picnic.

39.c3 dxc3+ 40.Kxc3 Re6


41.Rxe6 Kxe6 42.b6 Kd6


43.Rxh6+ Kd7 44.b7 Kc7 45.Re6 Kxb7 46.Kc4 Kc7


47.Kxc5 Kd7 48.Kd5 Rxe7 49.Rxe7+ Kxe7


Black keeps capturing pawns, and his position keeps getting worse.

50.h5 Kf6 51.g4 Kg5 52.Kd6 Kxg4 53.h6 Kg5 54.h7 Kf4


55.h8Q Ke3 56.Qe8+ Kxd3 57.Qg6+ Kd2 58.Qb1 Ke3 59.Qa2 Kf4 60.Qxa5 Ke3 61.Qd5 Black resigned

Battle Fatigue (1)

Slam-bang chess battles can be exhausting, especially when they involve off-beat openings like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). Picking a good move, time after time, builds pressure, and sometimes the result is picking a not-so-good move, simply out of battle fatigue. Here is an example.

9.f4 Ng4 10.e5 Qh4 11.h3 Nf5 12.Qf3 Ng3 13.Re1 Nh1

Black's counter-attack is quite scary. White can hold on, and even drive back the enemy, according to Rybka 3, with 14.Bd2 Ng6 15.Rd1 Nf5 16.Be1 Qe2 17.hxg4, but that's a computer talking, not a human being.

SIRMO

While preparing "Jerome Gambit for Dummies (5)" I realized that I had published only two games of the Jerome Gambit thematic tournament winner, SIRMO: plummy - SIRMO, chessworld.net, 2007 (0-1, 49) and Bullit52 - SIRMO, chessworld.net, 2007 (0-1, 12).
I think I may have unfairly shied away from his games because SIRMO prefers the "modern" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) variations – not playing 5.Nxe5+ after 4...Kxf7 – and because a number of his wins feature a certain amount of wizardry...
Here are SIRMO's Jerome Gambit wins with white.

An International Master Refutes the Jerome Gambit


International Master Gary Lane's latest book, The Greatest Ever Chess Tricks and Traps (Everyman Chess, 2008) is a very entertaining and educational collection addressing the notion that "There is no easier way to win a game of chess than by luring your opponent into a devious trap."

Lane covers the Jerome Gambit of course, and annotates the game Banks - Karmark, internet, 2007, (although he mistakenly labels it a blitz game).

His main analysis of the Jerome:

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6!


I think this is the best way to defend: allowing one of the extra pieces to be taken, and in return obtaining a solid position with extra material.

8.fxe5 dxe5 9.Nc3
This is the right time for White to offer a draw, but if the offer is declined you should remember that it is frowned upon to cry at the board.

9...Nf6 10.Qh4 Rf8 11.d3 Kf7 12.Bg5 Kg8
Black has artificially castled and now has a big advantage, thanks to his extra piece for just one pawn.



I was pleased to see that 9.Nc3 was not in my Jerome Gambit database – but if that is the move IM Lane sees as best for White, I will add it to my repertoire!

The extraordinary and forgotten Jerome Gambit



I always enjoy John Elburg's book reviews.

Of course, who wouldn't enjoy his look at International Master Gary Lane's latest title, The Greatest Ever Chess Tricks and Traps ? --




Gary Lane provides the reader in this greatest ever chess tricks and traps book with a amazing collection short cuts.
Some are well known as the seven move lost from the poor Ree against Petrosian,at the Wijk aan Zee tournament from 1971, but many others as for example the game Banks – Karmmark, Internet Blitz 2007, are brand new.
Where white went for the extraordinary and forgotten Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+?
These moves, as we can read in this entertaining work from Lane is named after the American player Alonzo Wheeler Jerome 1834-1902 of Paxton, Illinois, and was analysed in the American Chess Journal in 1874. It has to be remembered that in the 19th century people liked to attack and never defend.
This book from Lane is not only a very exciting game collection but above all, a very good read.
Nearly all major openings are divided with a instructive example of play and all games in this book are pleasantly indexed with names and openings.
All together I counted around 110 complete games where some are good for over two pages of text!
As for example the following victory in the opening: Skurski, Jan (2069) - Gasik, Piotr (2189) [B12] POL-ch sf Polanczyk (6), 09.11.2000 1.e4 c6 2.d4 d5 3.f3 dxe4 4.fxe4 e5 5.Nf3 exd4 6.Bc4 Bb4+ 7.c3 dxc3 8.Bxf7+ Kxf7 9.Qxd8 cxb2+ 10.Ke2 bxa1Q 11.Ng5+ Kg6 12.Qe8+ Kh6 13.Ne6+ g5 14.Bxg5# 1-0
As we can read in the book from Lane black has tried to avoid defeat at this point with no success.

Conclusion: This book is overloaded with unbelievable shortcuts!

International Master Gary Lane

International Master Gary Lane's "Opening Lanes" column at ChessCafe is a constant source of information and merriment for club players looking to add lines that are a bit unusual (or more than a bit) to their opening play.
In two recent columns, IM Lane took a look at the Jerome Gambit, with the encouragement of Jerome Gambit Gemeinde member Pete Banks, who provided an introduction via several games. In fact, he began coverage in the second column with the note
Finally, last month’s feature on the bizarre Jerome Gambit prompted a flood of e-mails; the majority of which were delighted to see this wacky opening.
Surprisingly, the Jerome Gambit can have that effect on people.
Go figure.

I was intrigued because this gambit was unknown to me, but after some research I think it is has an interesting history. The opening is named after the American player Alonzo Wheeler Jerome (1834-1902) of Paxton, Illinois, which was analysed in the American Chess Journal 1874.
It has to be remembered that over 100 years ago people liked to attack and never defend, but even so his gambit is extraordinary.
IM Lane then annotates a game (given in "My Jerome Gambit Database" as "blackburne - karmmark") and it's hard not to at least give his jumping-off points...

Let us first look at the perfect example: Pete Banks-Karmmark Internet 2007 1 e4 e5 2 Nf3 Nc6 3 Bc4 Bc5 4 Bxf7+? The starting point of the Jerome Gambit. The great benefit of playing this on the Internet is that it is the last move your opponent is expecting. 4…Kxf7 5 Nxe5+ Yes, this really is an established line. I think anyone with good manners playing Black would now kindly ask their opponent if they wanted to take their move back.

When White wraps the game up quickly and in good style, the annotator wryly comments

Yes, the Jerome Gambit does look like a forced win, but Black has one or two defences at his disposal. I think Mr. Banks benefits from being stronger than his opponent, but it is a fun way to test the opening.


That is some of what makes International Master Gary Lane such a hit with the average player: he's willing to consider ideas off of the beaten path, and he rarely overlooks the critical ingredient, "fun," which makes chess such a tasty dish!

My Jerome Gambit Database


I have over 950 Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games in my database, allowing for transpositions.


I'm always looking for more.

Some are historical

Some are tragic modern over-the-board games

Some are sleepy affairs

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


In all about 7% are over-the-board games, 12% involve computers (person vs computer or computer vs computer), 2% are traditional (snail mail) correspondence games and 79% are games played on the internet (various time controls).

These statistics reflect the explosion of chess in general on the internet – as well as the continued challenge of unearthing historical games, as reflected in the two smallest per centages above. With good reason National Master Eric Schiller includes the Jerome Gambit, despite its untamed early life, among those he calls a "cyberspace gambit" in his Gambit Chess Openings (2002).

In fact, a ChessBase-generated graph of the games, distributed by year played, looks like a very skinny Bozo the Clown taking a nap on his back: his nose beeps up in the mid-1870s to mid-1880s and then there's very little in the sillouette until his large clown shoes explode in the 2000 to present era...
